Description

Die Erfindung bezieht sich auf eine Kraftsteckdose mit Kraftstecker für Drehstrommotoren, aus Eisen oder Leichtmetall hergestellt und ausgerüstet mit Einsätzen von Isoliermaterial (Steatit usw.) zur Aufnahme der Stromabnehmerkontakte für die Phasen und Nullung.The invention relates to a power socket with a power plug for three-phase motors, made of iron or light metal and equipped with Use of insulating material (steatite, etc.) to accommodate the current collector contacts for the phases and zeroing.

Gekennzeichnet ist die Kraftsteckdose mit dem Kraftstecker dadurch, daß die drei Phasenanschlüsse des Motors in der Kraftsteckdose im Dreieck angeordnet sind und der Nulleiteranschluß bzw. die Nulleitersteckerbuchse in der Mitte des Dreiecks der Phasenanschlüsse ist. Die mittlere Phase ist in der Kraftsteckdose an zwei senkrecht übereinanderliegenden und elektrisch miteinander verbundenen Steckerbuchsen derart angeschlossen,, daß beim Umstecken oder Umwechseln des Kraftsteckers eine Drehrichtungsumkehr des Motors erzielt und die vorschriftsmäßige Nullung erreicht ist, was die Kraftsteckdose besonders kennzeichnet.The power socket with the power plug is characterized by that the three phase connections of the motor in the power socket are arranged in a triangle and the neutral connection or the neutral connector in the middle of the Triangle of phase connections is. The middle phase is in the power socket at two vertically one above the other and electrically connected to each other so connected ,, that when plugging or changing the power connector a Reversal of the direction of rotation of the motor achieved and the correct zeroing achieved is what characterizes the power socket.

Bei der bisherigen Anordnung der Kontakt-Buchsen in den Kraftsteckdosen mit drei und selbst auch mit vier Kontaktstiften war es nicht möglich, durch Umstecken oder Umwechseln des Kraftsteckers eine Drehrichtungsumkehr des Motors. zu erreichen und zugleich auch die vorschriftsmäßige Nullung zu erzielen. Durch die Erfindung, Anordnung der drei Phasenanschlüsse in der Kraftsteckdose im Dreieck, wobei die mittlere Phase mit zwei Steckerbuchsen ausgerüstet ist, die elektrisch miteinander verbunden sind, ist es möglich, durch Umstecken oder Umwechseln des Kraftsteckers eine Drehrichtungsumkehr beim Motor zu erreichen und zugleich die vorschriftsmäßige Nul-Ittng zu erzielen, was bisher nicht möglich war.With the previous arrangement of the contact sockets in the power sockets with three or even four contact pins it was not possible by repositioning or changing the power connector, reversing the direction of rotation of the motor. to reach and at the same time to achieve the correct zeroing. Through the invention, Arrangement of the three phase connections in the power socket in a triangle, with the middle phase is equipped with two sockets, which are electrically connected to each other connected, it is possible by plugging or changing the power connector to achieve a reversal of the direction of rotation of the motor and at the same time the correct To achieve zero-ittng, which was previously not possible.

Ferner fällt der bisherige notwendige Umschalter zur Drehrichtungsumkehr weg, welcher vor allem in landwirtschaftlichen Betrieben immer Anlaß zu Störungen gab und auch zu Motordefekten führte, neben den hohen Anschaffungskosten. Die Kraftsteckdose vereinfacht auch noch die Motorbedienung wesentlich.Furthermore, the previous switch for reversing the direction of rotation is no longer necessary away, which is always a cause of disturbances, especially in agricultural operations existed and also led to engine defects, in addition to the high acquisition costs. The power socket also simplifies the motor operation considerably.
