Description

L'invention est relative à un disjoncteur télécommandé formé par l'assemblage d'un bloc de télécommande et d'un disjoncteur multipolaire à boîtier isolant,
le disjoncteur renfermant:

  • un premier mécanisme à genouillère associée à un déclencheur automatique, et à une manette de commande,
  • un système de contacts séparables par pôle, actionné par un barreau de commutation en liaison mécanique avec le premier mécanisme,
The invention relates to a remote controlled circuit breaker formed by the assembly of a remote control unit and a multipole circuit breaker with insulating housing,
the circuit breaker containing:
  • a first toggle mechanism associated with an automatic trigger, and with a control lever,
  • a system of contacts separable by pole, actuated by a switching bar in mechanical connection with the first mechanism,

le bloc de télécommande étant adaptable à la face avant du boîtier et comportant :

  • un tiroir de transmission dans lequel s'engage la manette du disjoncteur,
  • un deuxième mécanisme relié au tiroir par un levier entraîneur , et équipé d'une came de réarmement entraînée par un organe moto-réducteur ou par une commande manuelle de secours, pour accumuler de l'énergie mécanique dans au moins un ressort de fermeture, ladite came ayant un premier secteur d'armement, et un deuxième secteur de libération d'un galet solidaire du levier entraîneur.
the remote control unit being adaptable to the front face of the housing and comprising:
  • a transmission drawer into which the circuit breaker handle engages,
  • a second mechanism connected to the drawer by a driving lever, and equipped with a rearming cam driven by a geared motor or by a manual emergency control, for accumulating mechanical energy in at least one closing spring, said cam having a first arming sector, and a second sector for releasing a roller secured to the driving lever.

Les mécanismes de réarmement faisant coopérer une came de commande et un galet d'un levier entraîneur sont bien connus pour assurer l'actionnement d'un ressort de fermeture dans le sens de la compression et de la détente. Un tel dispositif est illustré dans le document EP-A-222.645, qui forme la base du préambule de la revendication 1, dans lequel un étage d'accrochage spécial assure le maintien de la came du mécanisme dans l'état armé. L'étage d'accrochage comporte à cet effet un cliquet de fermeture associé à un verrou à demi-lune, lequel est piloté soit manuellement par un bouton poussoir, soit électriquement par excitation d'un électroaimant d'enclenchement. La présence du cliquet est indispensable, à cause de l'action antagoniste d'un couple de déséquilibre sur la came, le couple résultant de la tension du ressort et de l'angle formé par la réaction du galet sur la came, et la ligne passant par le galet et l'axe de la came. La réalisation d'un tel dispositif est compliqué, et augmente le coût de revient du mécanisme.The reset mechanisms making a control cam and a roller of a driving lever cooperate are well known for ensuring the actuation of a closing spring in the direction of compression and expansion. Such a device is illustrated in document EP-A-222,645, which forms the base of the preamble of claim 1, in which a special hooking stage maintains the cam of the mechanism in the armed state. The attachment stage comprises for this purpose a closing pawl associated with a half-moon lock, which is controlled either manually by a push button, or electrically by excitation of an engagement electromagnet. The presence of the pawl is essential, because of the antagonistic action of an imbalance torque on the cam, the torque resulting from the spring tension and the angle formed by the reaction of the roller on the cam, and the line passing through the roller and the axis of the cam. The production of such a device is complicated, and increases the cost price of the mechanism.

L'objet de l'invention consiste à améliorer la réalisation d'un mécanisme de télécommande pour un disjoncteur multipolaire.The object of the invention is to improve the production of a remote control mechanism for a multipole circuit breaker.

Le disjoncteur télécommandé est caractérisé en ce que la came de réarmement comporte un surface d'appui conformée pour stabiliser le galet en position armée du levier entraîneur grâce au passage de la ligne d'action de la réaction R du galet par l'arbre de transmission de la came de réarmement, et que l'organe moto-réducteur est doté de moyens pour assurer un arrêt quasi-instantané de la came de réarmement lorsque le galet arrive au voisinage de la surface d'appui.The remote-controlled circuit breaker is characterized in that the resetting cam has a shaped support surface to stabilize the roller in the armed position of the driving lever thanks to the passage of the action line of the reaction R of the roller by the drive shaft of the reset cam, and that the geared motor member is provided with means for ensuring an almost instantaneous stop of the reset cam when the roller arrives in the vicinity of the bearing surface.

La position armée du galet sur la surface d'appui de la came est stable et aucune motricité ne s'exerce sur la came, étant donné que la réaction sur la came est alignée avec la ligne passant par le galet et l'arbre de la came. Un cliquet de verrouillage spécial n'est donc pas nécessaire pour maintenir la came en équilibre. Il est également possible de supprimer l'électro-aimant de fermeture, étant donné que l'ordre électrique de fermeture est appliqué directement au moto-réducteur. La structure du deuxième mécanisme est ainsi simplifiée.The armed position of the roller on the bearing surface of the cam is stable and no traction is exerted on the cam, since the reaction on the cam is aligned with the line passing through the roller and the shaft of the cam. A special locking pawl is therefore not necessary to keep the cam in balance. It is also possible to suppress the closing electromagnet, since the electric closing order is applied directly to the gear motor. The structure of the second mechanism is thus simplified.

L'ouverture du disjoncteur, et l'accumulation d'énergie dans le ressort de fermeture s'effectuent au moyen de l'ensemble came et galet, l'arbre de la came étant actionné électriquement par l'organe moto-réducteur, ou manuellement par la commande de secours. La fermeture brusque du disjoncteur résulte du franchissement d'un point dur du galet sur la came, cette dernière étant actionné électriquement par l'organe moto-réducteur ou manuellement au moyen d'un bouton poussoir de fermeture.The opening of the circuit breaker, and the accumulation of energy in the closing spring is effected by means of the cam and roller assembly, the cam shaft being actuated electrically by the gear motor, or manually by the emergency command. The sudden closing of the circuit breaker results from the crossing of a hard point of the roller on the cam, the latter being actuated electrically by the gear motor or manually by means of a closing push button.

De préférence, la forme de la surface d'appui de la came d'armement est plane ou incurvée.Preferably, the shape of the bearing surface of the cocking cam is flat or curved.

L'usage d'un moteur du type vibrant permet d'obtenir un arrêt instantané de la came d'armement en position armée.The use of a motor of the vibrating type makes it possible to obtain an instantaneous stop of the arming cam in the armed position.

Selon une caractéristique préférée de l'invention, le deuxième mécanisme est pourvu d'un premier bouton poussoir de fermeture manuelle coopérant avec des moyens de déplacement de la came de réarmement vers la position désarmée, dans laquelle le galet se trouve au voisinage du deuxième secteur autorisant la détente brusque du ressort de fermeture.According to a preferred characteristic of the invention, the second mechanism is provided with a first manual closing push-button cooperating with means for moving the reset cam to the disarmed position, in which the roller is in the vicinity of the second sector. allowing the abrupt relaxation of the closing spring.

Selon une autre caractéristique préférée de l'invention, le deuxième mécanisme est doté d'un deuxième bouton poussoir d'ouverture manuelle coopérant avec un poussoir de déclenchement du premier mécanisme .According to another preferred characteristic of the invention, the second mechanism is provided with a second manual opening push-button cooperating with a push-button for triggering the first mechanism.

D'autres avantages et caractéristiques préférées ressortiront plus clairement de la description qui va suivre d'un mode de mise en oeuvre de l'invention, donné à titre d'exemple et représenté aux dessins annexés, dans lesquels:Other preferred advantages and characteristics will emerge more clearly from the description which follows of an embodiment of the invention, given by way of example and shown in the appended drawings, in which:

La figure 1 est une vue en perspective d'un mode de réalisation du disjoncteur télécommandé selon l'invention.Figure 1 is a perspective view of an embodiment of the remote controlled circuit breaker according to the invention.

Les figures 2 et 3 montrent deux vues en perspective de droite et de gauche du bloc de télécommande selon un mode de réalisation de l'invention.Figures 2 and 3 show two perspective views of right and left of the remote control unit according to an embodiment of the invention.

La figure 4 est une vue schématique en élévation du deuxième mécanisme du bloc de télécommande, représenté en position armée.Figure 4 is a schematic elevational view of the second mechanism of the remote control unit, shown in the armed position.

La figure 5 est une vue en coupe du deuxième mécanisme selon la ligne 5-5 de la figure 3.FIG. 5 is a sectional view of the second mechanism along line 5-5 of FIG. 3.

La figure 6 montre le disjoncteur en position ouvert, et la télécommande à l'état armé, sans action sur le bouton poussoir de fermeture.Figure 6 shows the circuit breaker in the open position, and the remote control in the armed state, without action on the closing push button.

La figure 7 représente le disjoncteur en position fermé, et la télécommande à l'état désarmé après enfoncement du bouton poussoir de fermeture.Figure 7 shows the circuit breaker in the closed position, and the remote control in the disarmed state after pressing the close push button.

Les figures 8 et 9 sont des vues similaires aux figures 6 et 7, respectivement avant et après action sur le bouton poussoir d'ouverture.Figures 8 and 9 are views similar to Figures 6 and 7, respectively before and after action on the opening push button.

Les figures 1 et 6 à 9 montrent un disjoncteur télécommandé 10 formé par l'assemblage d'un bloc de télécommande 11 à accumulation d'énergie, et d'un disjoncteur 12 à boîtier 13 isolant moulé. Le disjoncteur 12 est du type multipolaire renfermant un système de contacts séparables 14 (figures 6 et 8), dont le contact mobile 16 de chaque pôle est positionné dans un orifice du barreau 18 de commutation.Figures 1 and 6 to 9 show a remote controlled circuit breaker 10 formed by the assembly of a remote control unit 11 with energy accumulation, and a circuit breaker 12 with molded insulating housing 13. The circuit breaker 12 is of the multipolar type containing a separable contact system 14 (FIGS. 6 and 8), the movable contact 16 of each pole is positioned in an orifice of the switching bar 18.

Le barreau 18 est actionné par un premier mécanisme 20 de commande piloté par un déclencheur 22 sensible à un courant de surcharge, et coopérant avec un maneton ou manette 24 pivotante faisant saillie du boîtier 13. Le déclencheur 22 peut être électronique ou magnétothermique. Un crochet 26 de déclenchement (figures 8 et 9) est monté à pivotement sur un axe 28 fixe, et est équipé d'une surface d'accrochage 30 coopérant en position de verrouillage avec un verrou 32 articulé sur un axe 34. Le verrou 32 est maintenu en position de verrouillage par un accrochage 36 en forme de demi-lune, commandé par le déclencheur 22 de manière à provoquer l'ouverture automatique du disjoncteur lors de l'apparition d'un défaut. Le crochet 26 est relié au barreau 18 par une genouillère (non représentée), et la manette 24 peut occuper trois positions distinctes comprenant :

  • une première position fermée (figures 7 et 8) correspondant à la fermeture du système de contacts 14, et à l'extension de la genouillère suite à l'intervention du bloc de télécommande 11 après réception d'un ordre de fermeture;
  • une deuxième position d'ouverture correspondant à l'ouverture du système de contacts 14 suite à l'intervention du bloc de télécommande 11 après réception d'un ordre d'ouverture;
  • une troisième position de déclenchement (non représentée) correspondant à la séparation des contacts 14 suite à la brisure de la genouillère après déverrouillage du crochet 26 par le verrou 32 suite à l'émission d'un ordre de déclenchement issu du déclencheur 22.
The bar 18 is actuated by a first control mechanism 20 piloted by a trigger 22 sensitive to an overload current, and cooperating with a pivoting lever or lever 24 projecting from the housing 13. The trigger 22 can be electronic or magnetothermal. A trigger hook 26 (FIGS. 8 and 9) is pivotally mounted on a fixed axis 28, and is equipped with a hooking surface 30 cooperating in the locking position with a lock 32 articulated on an axis 34. The lock 32 is held in the locked position by a hook 36 in the shape of a half-moon, controlled by the release 22 so as to cause the automatic opening of the circuit breaker when a fault occurs. The hook 26 is connected to the bar 18 by a toggle joint (not shown), and the lever 24 can occupy three distinct positions comprising:
  • a first closed position (FIGS. 7 and 8) corresponding to the closing of the contact system 14, and to the extension of the toggle switch following the intervention of the remote control unit 11 after receipt of a closing order;
  • a second opening position corresponding to the opening of the contact system 14 following the intervention of the remote control unit 11 after receipt of an opening order;
  • a third tripping position (not shown) corresponding to the separation of the contacts 14 following the breaking of the toggle joint after unlocking the hook 26 by the latch 32 following the issuance of a tripping order originating from the tripping device 22.

Le système de contacts 14 comporte à titre d'exemple un pont de contact 16 rotatif à double coupure coopérant avec une paire de contacts fixes 38, 40, tel que décrit dans le document FR-A-2.622.347 de la demanderesse. Il est bien entendu que tout autre dispositif, notamment à simple coupure, peut être utilisé.The contact system 14 comprises, by way of example, a rotary double-contact contact bridge 16 cooperating with a pair of fixed contacts 38, 40, as described in document FR-A-2.622.347 of the applicant. It is understood that any other device, in particular a single cut-out device, can be used.

A l'intérieur du bloc de télécommande 11 se trouve un deuxième mécanisme 42 agencé entre deux platines 44, 46 de support, s'étendant parallèlement l'une à l'autre dans la partie centrale du bloc. Le mécanisme 42 est doté d'un système accumulateur d'énergie 48 comprenant un ressort de fermeture 50 monté sur un support télescopique 52 agencé entre une butée 54 fixe, et un doigt 56 de transmission d'un levier entraîneur 58. Un tel système accumulateur d'énergie 48 est décrit à titre d'exemple dans le document EP-A-222.645.Inside the remote control unit 11 is a second mechanism 42 arranged between two support plates 44, 46, extending parallel to one another in the central part of the unit.

Le profil de la came 64 présente un premier secteur 70 d'armement du ressort de fermeture, et un deuxième secteur 72 de libération du galet 68 autorisant un mouvement de pivotement brusque du levier entraîneur 58 dans le sens des aiguilles d'une montre sous l'action de détente du ressort de fermeture 50.The driving lever 58 is pivotally mounted on an axis 60 integral with the plates 44, 46, and is equipped, opposite the axis 60, with a cleat 62 for driving intended to come into engagement with the lever 24 to ensure closing the contacts 38, 40, 16 of the circuit breaker 12. The mechanism 42 further comprises a reset cam 64 mounted on a transverse transmission shaft 66 extending perpendicularly to the plates 44, 46 and to the driving lever 58. The cam resetting 64 cooperates with a roller 68 mounted for free rotation on the driving lever 58. The profile of the cam 64 has a first sector 70 for arming the closing spring, and a second sector 72 for releasing the roller 68 allowing movement of abrupt pivoting of driving lever 58 clockwise under the detent action of the closing spring 50.

Le deuxième mécanisme 42 est intercalé entre un organe moto-réducteur 74 (à gauche sur la figure 5), et une commande manuelle 76 de secours (à droite sur la figure 5). L'une des extrémités de l'arbre de transmission 66 est reliée à une première roue 78 dentée coopérant à engrenage avec une deuxième roue 80 dentée entraînée par le moteur 82. La deuxième roue 80 présente un diamètre inférieur à celui de la première roue 78 pour former un étage de réduction de vitesse. L'autre extrémité de l'arbre 66 est solidaire de la commande manuelle 76 comprenant un levier de manoeuvre 84 à mouvement alternatif associé à un cliquet 86 en engagement avec une troisième roue dentée 88 de l'arbre 66.The second mechanism 42 is interposed between a motor-reducing member 74 (on the left in FIG. 5), and a manual emergency control 76 (on the right in FIG. 5). One of the ends of the transmission shaft 66 is connected to a first toothed wheel 78 cooperating with a gear with a second toothed wheel 80 driven by the motor 82. The second wheel 80 has a diameter smaller than that of the first wheel 78 to form a speed reduction stage. The other end of the shaft 66 is integral with the manual control 76 comprising an operating lever 84 with reciprocating movement associated with a pawl 86 in engagement with a third toothed wheel 88 of the shaft 66.

Sur l'arbre 66 est monté d'autre part une première came auxiliaire 90 de commande de fermeture destinée à coopérer avec un levier d'entraînement 92 sous l'action d'un premier bouton poussoir 94 de fermeture. La première came auxiliaire 90 et le levier d'entraînement 92 se trouvent sensiblement dans le même plan, en étant intercalé entre la platine 46 et une deuxième came auxiliaire 96 de commande d'un système de contacts de signalisation (non représenté).On the shaft 66 is mounted on the other hand a first auxiliary cam 90 for closing control intended to cooperate with a drive lever 92 under the action of a first push button 94 for closing. The first auxiliary cam 90 and the drive lever 92 are substantially in the same plane, being interposed between the plate 46 and a second auxiliary cam 96 for controlling a signaling contact system (not shown).

Le moteur 82 comporte avantageusement un électro-aimant 98 à circuit magnétique en U équipé de deux bobines d'excitation, et d'une armature 100 montée à oscillation sur un axe 102 et coopérant avec un système de transmission unidirectionnel à roues libres (non représenté), transformant le mouvement de vibration de l'armature 100 en un mouvement de rotation progressif ou pas à pas de la deuxième roue 80 dentée. Un tel moteur est décrit à titre d'exemple dans le document FR-A-2.654.254. Il est clair que tout autre type de moteur peut être utilisé pour entraîner l'arbre 66 dans un même sens de rotation.The motor 82 advantageously comprises an electromagnet 98 with a U-shaped magnetic circuit equipped with two excitation coils, and an armature 100 mounted to oscillate on an axis 102 and cooperating with a unidirectional freewheel transmission system (not shown). ), transforming the vibration movement of the armature 100 into a progressive or step-by-step rotation movement of the second toothed wheel 80. Such an engine is described by way of example in document FR-A-2,654,254. It is clear that any other type of motor can be used to drive the shaft 66 in the same direction of rotation.

La came de réarmement 64 est pourvue d'une troisième surface d'appui 104 agencée entre le premier secteur 70 et le deuxième secteur 72 pour le maintien stable du galet 68 en position armée du deuxième mécanisme 42 de télécommande. La forme de la surface d'appui 104 est sensiblement plane, ou légèrement incurvée selon une cuvette, et la ligne d'action de la réaction R (figure 4) du galet 68 sur la surface d'appui 104 passe en position armée par l'axe 66 de la came 64. La force de réaction R est sensiblement perpendiculaire à la surface d'appui 104, et n'engendre aucun couple tendant à rompre l'état d'équilibre de la came 64 et du levier entraîneur 58.The reset cam 64 is provided with a third bearing surface 104 arranged between the first sector 70 and the second sector 72 for the stable maintenance of the roller 68 in the armed position of the second remote control mechanism 42. The shape of the support surface 104 is substantially flat, or slightly curved in a bowl, and the line of action of the reaction R (FIG. 4) of the roller 68 on the support surface 104 passes into the position armed by the the axis 66 of the cam 64. The reaction force R is substantially perpendicular to the bearing surface 104, and does not generate any torque tending to break the state of equilibrium of the cam 64 and of the driving lever 58.

Le deuxième mécanisme 42 est équipé en plus d'un deuxième bouton poussoir 106 d'ouverture (figures 8 et 9) coopérant avec un poussoir de déclenchement 108 de l'accrochage 36 du premier mécanisme 20. Le poussoir 106 est intercalé entre la demi-lune de l'accrochage 36 et l'extrémité inférieure du bouton poussoir 106.The second mechanism 42 is additionally equipped with a second opening push button 106 (FIGS. 8 and 9) cooperating with a push button for triggering 108 of the attachment 36 of the first mechanism 20. The push button 106 is interposed between the half moon of the attachment 36 and the lower end of the push button 106.

Le maneton 24 du disjoncteur est engagé dans un tiroir 110 monté à translation libre dans des glissières 112 rectilignes des deux platines 44, 46. Le tiroir 110 est sollicité par le taquet 62 du levier entraîneur 58 entre les positions d'ouverture et de fermeture du maneton 24.The crank pin 24 of the circuit breaker is engaged in a drawer 110 mounted for free translation in straight rails 112 of the two plates 44, 46. The drawer 110 is biased by the cleat 62 of the driving lever 58 between the open and closed positions of the pin 24.

Le fonctionnement du disjoncteur télécommandé 10 est le suivant :The operation of the remote-controlled circuit breaker 10 is as follows:

La figure 9 montre le disjoncteur en position ouvert déclenché, et le bloc de télécommande 11 à l'état désarmé. Le déverrouillage du verrou 32 par l'accrochage 36 provoque l'ouverture du système de contacts 14, mais le maneton 24 reste immobilisé par le levier entraîneur 58 et le tiroir 110 dans la position de gauche correspondant à la position de fermeture. La libération du verrou 32 intervient sur la figure 9 par un ordre manuel suite à l'enfoncement du deuxième bouton poussoir d'ouverture, lequel agit sur le poussoir 108 de déclenchement. Le mouvement de libération du verrou 32 peut également être opéré de manière automatique, soit par le déclencheur 22 en cas de détection d'un défaut, soit par un auxiliaire de déclenchement à distance du type MX à émission (non représenté). Le ressort 50 du système accumulateur 48 d'énergie est détendu, et le levier entraîneur 58 est en appui contre une butée 114 de fin de course.FIG. 9 shows the circuit breaker in the tripped open position, and the remote control unit 11 in the disarmed state. Unlocking the lock 32 by the hooking 36 causes the opening of the contact system 14, but the crank pin 24 remains immobilized by the driving lever 58 and the drawer 110 in the left position corresponding to the closed position. The release of the latch 32 takes place in FIG. 9 by a manual command following the depressing of the second opening push button, which acts on the push button 108 for triggering. The release movement of the latch 32 can also be operated automatically, either by the trigger 22 in the event of detection of a fault, or by an MX type remote release auxiliary with emission (not shown). The spring 50 of the energy storage system 48 is relaxed, and the driving lever 58 is in abutment against an end stop 114.

A partir de la position de la figure 9, il est possible après relâchement du bouton poussoir 106, de réarmer le bloc de télécommande 11, soit automatiquement par un ordre d'excitation transmis au moteur 82, soit manuellement par un mouvement alternatif de pompage du levier de manoeuvre 84 intégré dans la commande de secours 76. L'arbre 66 principal de transmission tourne toujours dans le même sens quel que soit le mode d'entraînement choisi.From the position of FIG. 9, it is possible after releasing the push button 106, to reset the remote control unit 11, either automatically by an excitation command transmitted to the motor 82, or manually by an alternating pumping movement of the operating lever 84 integrated in the emergency control 76. The main drive shaft 66 always rotates in the same direction regardless of the drive mode chosen.

La came de réarmement 64 tourne en rotation avec l'arbre 66 dans le sens des aiguilles d'une montre, et le premier secteur 70 coopère avec le galet 68 en entraînant le levier entraîneur 58 autour de l'axe 60 dans le sens inverse des aiguilles d'une montre, de manière à assurer une compression du ressort 50 de fermeture. L'arrêt de la came 64 intervient lorsque le galet 68 se trouve en contact avec la surface d'appui 104, après que le levier entraîneur 58 ait déplacer simultanément le maneton 24 du disjoncteur 12 vers la position d'ouverture par l'intermédiaire du tiroir 110.The reset cam 64 rotates in rotation with the shaft 66 in the clockwise direction, and the first sector 70 cooperates with the roller 68 by driving the driving lever 58 around the axis 60 in the opposite direction of the clockwise, so as to ensure compression of the closing spring 50. The cam 64 stops when the roller 68 is in contact with the bearing surface 104, after the driving lever 58 has simultaneously moved the crank pin 24 of the circuit breaker 12 to the open position by means of the drawer 110.

Dans la position de la figure 6, le disjoncteur 12 est en position ouvert, et le bloc de télécommande 11 se trouve à l'état armé. L'interruption de l'alimentation du moteur 82 vibrant permet d'obtenir un arrêt instantané de la came 64 d'armement lorsque le galet 68 arrive sur la surface d'appui 104. Aucune motricité ne s'exerce sur la came 64 dans cette position d'équilibre qui reste stable, malgré l'absence d'un étage d'accrochage auxiliaire, étant donné le passage de la réaction R du galet 68 par l'axe 66 de la came de réarmement 64.In the position of Figure 6, the circuit breaker 12 is in the open position, and the remote control unit 11 is in the armed state. The interruption of the power supply to the vibrating motor 82 makes it possible to obtain an instantaneous stop of the arming cam 64 when the roller 68 arrives on the bearing surface 104. No traction is exerted on the cam 64 in this equilibrium position which remains stable, despite the absence of an auxiliary latching stage, given the passage of the reaction R of the roller 68 through the axis 66 of the reset cam 64.

A partir de la position de la figure 6, un enfoncement du premier bouton poussoir 94 de fermeture déplace la came de réarmement 64 en rotation dans le sens des aiguilles d'une montre, par l'intermédiaire du levier 92 d'entraînement de la première came auxiliaire 90. Le galet 68 quitte la surface d'appui 104, et arrive dans le deuxième secteur 72, autorisant la détente du ressort 50 accumulateur d'énergie, et la fermeture brusque des contacts du disjoncteur 12 par l'action du levier entraîneur 58 (voir figure 7). Le taquet 62 ramène le maneton 24 vers la gauche correspondant à la position de fermeture. Dans la figure 7, le disjoncteur 12 est fermé, et le bloc de télécommande 11 est désarmé.From the position of FIG. 6, a depression of the first closing push button 94 moves the reset cam 64 in rotation clockwise, by means of the lever 92 for driving the first auxiliary cam 90. The roller 68 leaves the bearing surface 104, and arrives in the second sector 72, authorizing the relaxation of the spring 50 energy accumulator, and the abrupt closing of the contacts of the circuit breaker 12 by the action of the driving lever 58 (see Figure 7). The stopper 62 brings the pin 24 to the left corresponding to the closed position. In Figure 7, the circuit breaker 12 is closed, and the remote control unit 11 is disarmed.

L'état de l'appareil dans la figure 8 correspond à celui de la figure 7, après relâchement du premier bouton poussoir 94 de fermeture. Dans cette position, on peut transiter vers l'état de la figure 9, après action sur le deuxième bouton poussoir 106 d'ouverture.The state of the device in FIG. 8 corresponds to that of FIG. 7, after releasing the first push button 94 for closing. In this position, one can transit to the state of FIG. 9, after action on the second opening push button 106.

Il est également concevable à partir de la position de la figure 7 de réarmer le bloc de télécommande 11 et d'ouvrir le disjoncteur 12 par excitation du moteur 82 ou par une action manuelle de la commande de secours 76.It is also conceivable from the position of FIG. 7 to reset the remote control unit 11 and to open the circuit breaker 12 by energizing the motor 82 or by manual action of the emergency control 76.

On remarque que l'ouverture du disjoncteur, et l'accumulation d'énergie dans le ressort 50 de fermeture s'effectue par les positions relatives de la came de réarmement 64 et du galet 68 du levier entraîneur 58, la came 64 étant actionnée électriquement par l'organe moto-réducteur 74, ou manuellement par la commande de secours 76. La fermeture brusque du disjoncteur 12 résulte du franchissement d'un point dur du galet 68 sur la came de réarmement, laquelle est actionnée électriquement par l'organe moto-réducteur 74 ou manuellement par enfoncement du bouton-poussoir de fermeture 94.Note that the opening of the circuit breaker, and the accumulation of energy in the closing spring 50 is effected by the relative positions of the reset cam 64 and the roller 68 of the driving lever 58, the cam 64 being actuated electrically. by the gear motor 74, or manually by the emergency control 76. The sudden closing of the circuit breaker 12 results from the crossing of a hard point of the roller 68 on the reset cam, which is electrically actuated by the motorcycle -reducer 74 or manually by depressing the closing push-button 94.
