Fig. 2 is that release shown in Figure 1 moves signal when reset of breaker.
Embodiment
As shown in Figure 1, the structural representation of the automatic reset mechanism of the magnetictrip that the present invention relates to for the present invention.This resetting device is located between the upper and lower shell (see among the figure 10), comprise contact mechanism 1, handle 2, described contact mechanism 1 is around first rotating shaft, 5 rotations, and handle 2 is around second rotating shaft, 6 rotations, be provided with connecting rod 9 between contact mechanism 1 and the handle 2, so contact mechanism 1 links with handle 2.When contact mechanism 1 rotated, handle 2 also can and then rotate; Perhaps when handle 2 rotated, contact mechanism 1 and then rotated.Contact mechanism 1 is provided with snap close piece 11, and this snap close piece 11 equally can be around first rotating shaft, 5 rotations, and the bottom of snap close piece 11 (away from an end of first rotating shaft 5) is triggering portion 12.On Shell of circuit breaker, also be provided with the 3rd rotating shaft 7, have a release link 4 to be located in the 3rd rotating shaft 7, and rotate around the 3rd rotating shaft 7.See Fig. 1, the centre of handle 2, snap close piece 11 and magnetictrip 3 is located in the 3rd rotating shaft 7, and between magnetictrip 3 and the triggering portion 12 certain clearance is arranged.Release link 4 comprises that the rotor 41 of a cylindrical shape and two are from rotor 41 extended first, second faller 42,43 respectively.Described rotor 41 is articulated in the 3rd rotating shaft 7, can rotate around the 3rd rotating shaft 7.Described first faller 42 is located in the gap between push rod 31 and the triggering portion 12, when magnetictrip 3 is not worked, need leave the gap between first faller 42 and the triggering portion 12,, remove to promote snap close piece 11 for first faller, 42 enough impulsive forces to guarantee that push rod 31 stretches out.First faller 42 comprises is located at two not first, second contact sites 44,45 on the ipsilateral.Described first contact site 44 is used for contacting with triggering portion 12, and described second contact site 45 is used for contacting with the push rod 31 of magnetictrip 3.See figure, in the present embodiment, the head of first faller 42 (right side) is that the left side of first contact site, 44, the first fallers, 42 bodies is second contact site 45.When release link 4 is rotated counterclockwise around the 3rd rotating shaft 7, first contact site 44 can be run into triggering portion 12; When release link 4 turns clockwise around the 3rd rotating shaft 7, second contact site 45 can be run into push rod 31.Described second faller 42 comprises that the 3rd contact site 46, the three contact sites 46 need and second contact site, 45 homonymies.In the present embodiment, the 3rd contact site 46 is in the left side of second faller 43.Handle 2 is provided with driving lever 21, and when handle 2 rotates counterclockwise, driving lever 21 contacts with the 3rd contact site 46, release link 4 is done around the 3rd rotating shaft 7 clockwise rotated.Release link 4 has certain elasticity and rigidity, can produce a certain amount of twist and warping under moderate forces is used.The rotor 41 of release link 4 and the 3rd rotating shaft 7 are matched in clearance, that is to say that release link 4 and the 3rd rotating shaft 7 have certain clearance in rotating shaft axially, and release link 4 can freely be rotated around the 3rd rotating shaft 7 like this.Excessive for preventing that release link 4 from rotating counterclockwise angle, on housing, also be provided with limit shaft 8, this limit shaft 8 is located at the left side of second faller 43, can limit the slewing area that second faller 43 rotates counterclockwise.In addition, also be with torsion spring 22 in second rotating shaft 6, when handle 2 is rotated counterclockwise, torsion spring 22 can discharge the energy of storage.
The present invention's operation principle of the present invention is as follows:
As shown in Figure 1, breaker closing breaks down as circuit, and this moment, magnetictrip 3 obtained extraneous fault-signal, made magnetictrip 3 liftout attachments that push rod 31 is ejected (as shown by arrows).Ejecting force by push rod 31 promotes release link 4, and release link 4 rotates counterclockwise, and (snap close piece 11 rotates around first rotating shaft 5 the triggering portion 12 on first contact site, the 44 promotion snap close pieces 11 of first faller 42, as shown by arrows), thereby makes the smooth separating brake of circuit breaker.For the impulsive force that guarantees to promote snap close piece 11 enough big, release link 4 can freely be rotated (as shown by arrows) around the 3rd rotating shaft 7, effectively reduced the frictional force between release link 4 and the 3rd rotating shaft 7 like this, and push rod 31 has certain clearance with triggering portion 12, make release link 4 promote snap close piece 11 at short notice, circuit breaker generation separating brake.
In the process of circuit breaker tripping separating brake, as shown in Figure 2, contact mechanism 1 rotates counterclockwise, this moment, handle 2 also rotated counterclockwise (as shown by arrows) simultaneously, driving lever 21 on the handle 2 (with handle 2 one) utilizes the torsion of the torsion spring 22 of handle 2 to run into the 3rd contact site 46 of second faller 43, and promotion release link 4 clockwise rotates (as shown by arrows), and second contact site 45 on release link 4 first fallers 42 is being pressed the push rod 31 of magnetictrip 3, forces push rod 31 to be moved to the left push rod 31 up to magnetictrip 3 reset (as shown by arrows).Automatically finish electrical equipment release 3 by breaker open operation thus and reset, and ready for closing a floodgate.
Described release link 4 can freely be rotated around the 3rd rotating shaft 7 (when limit shaft 8 does not exist, but release link 4 complete cycles rotate), to act on very big impulsive force on the release link 4 in the moment that magnetictrip 3 liftout attachments eject push rod 31, thereby the amount of spin of release link 4 can't be determined.So add the amount of spin of a limit shaft 8 in release link 4 left sides, guarantee that also the driving lever 21 of handle 2 can reliably push second faller 43 of release link 4, make push rod 31 reliable reset of magnetictrip 3, thereby the button again of finishing circuit breaker resets simultaneously with restriction release link 4.
