Description
Gegenstand der Erfindung ist eine Anordnung zum Einschalten, von Schaltern unter Verwendung eines in den Stromkreis der Einschaltspule des Schalters eingeschalteten Zwischenrelais bzw. Zwischenschützes, dessen Erregerkreis durch einen Hilfskontakt am Schalter unterbrochen wird.The invention relates to an arrangement for switching on switches below Use of a switched on in the circuit of the closing coil of the switch Intermediate relay or contactor whose excitation circuit is connected to an auxiliary contact on the Switch is interrupted.
Gemäß der Erfindung wird der Hilfskontakt bereits bei Beginn der Schalterbewegung geöffnet, und es wird parallel zur Erregerwicklung des Relais (Schützes) ein Gleichrichter geschaltet, der den beim Unterbrechen des Erregerstromkreises auftretenden Ausgleichstrom Mndurchläßt, so daß der Abfall des Zwischenrelais so lange verzögert wird, bis der Schalter mit Sicherheit eingelegt wird. Reicht die Induktivität der Erregerwicklung nicht aus, um eine genügend große Verzögerungszeit zu erhalten, so kann man in Reihe mit der Erregerwicklung des Zwischenschützes noch eine Drosselspule schalten und parallel zu dieser Reihenschaltung den Gleichrichter legen. Als Gleichrichter eignen sich insbesondere Trockengleichrichter, beispielsweise Kupfer-Kupferoxyd-Gleichiichter. Durch die Anordnung nach der Erfindung erhält man gegenüber einer Anordnung, bei welcher der Erregerstromkreis des Zwischenrelais (-schützes) durch einen Hilfskontakt am Schalter erst dann geöffnet wird, wenn der Schalter eingelegt ist, den Vorteil, daß ein Ausschalten der Erregerspule des Zwischenrelais und damit der Einschaltspule des Schalters auch dann erfolgt, wenn der Schalter etwa auf halbem Wege hängenbleiben sollte.According to the invention, the auxiliary contact is already at the beginning of the switch movement opened, and a rectifier is connected in parallel to the excitation winding of the relay (contactor) to control the interruption of the excitation circuit occurring equalizing current Mnpasses, so that the drop of the intermediate relay is delayed until the switch is safely engaged will. If the inductance of the field winding is not sufficient to create a sufficiently large one To obtain delay time, one can in series with the field winding of the intermediate contactor still switch a choke coil and parallel to this series connection the Place rectifier. Dry rectifiers, for example, are particularly suitable as rectifiers Copper-copper oxide equalizers. By the arrangement according to the invention one obtains compared to an arrangement in which the excitation circuit of the intermediate relay (contactor) through an auxiliary contact the switch is only opened when the switch is inserted, the advantage that switching off the excitation coil of the intermediate relay and thus the switch-on coil of the Switch also takes place when the switch gets stuck about halfway should.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.
ι ist das Zwischenschütz, dessen Erregerwicklung über eine Drosselspule 4 und die Ruhekontakte 2 eines Schalters 5 mit der Gleichstromquelle verbunden ist. Zum Einschalten des Schützes dient ein Handschalter 6. Parallel zum Schütz und der Drosselspule liegt der Gleichrichter 7. Wird das Schütz eingeschaltet, so schließt es seinen Kontakt8 und erregt damit die Einschaltspule 3 des Schalters 5. Der Schalter wird eingeschaltet und unterbricht bereits im Beginn seiner Schaltbewegung den Ruhekontakt 2, so daß der Stromkreis für das Schütz unterbrochen wird. Durch den parallel liegenden Gleichrichter wird erreicht, daß die Unterbrechung funkenlos erfolgt und gleichzeitig der Abfall des Zwischenschützes so lange verzögert wird, bis der Schalter mit Sicherheit eingelegt worden ist. Nach einer gewissen Zeit öffnet dann das Schütz seinen Kontakt 8 und unterbricht damit die Einschaltspule 3 des Schalters. Die Erfindung kann auch angewendet werden für Relais, welche von einem Wechselstromnetz über Gleichrichter (Einweg-, Doppelweg- oder Mehrphasengleichrichter) gespeist werden.ι is the intermediate contactor, its field winding is connected to the direct current source via a choke coil 4 and the normally closed contacts 2 of a switch 5. To switch on a manual switch 6 serves for the contactor. The rectifier 7 is parallel to the contactor and the choke coil If the contactor is switched on, it closes its contact 8 and thus excites the closing coil 3 of switch 5. The switch is switched on and interrupts at the beginning its switching movement the normally closed contact 2, so that the circuit for the contactor is interrupted. By the parallel lying Rectifier ensures that the interruption takes place without spark and at the same time the dropping of the intermediate contactor is delayed until the switch has been inserted with certainty. After a The contactor then opens its contact 8 for a certain period of time, thereby interrupting the closing coil 3 of the switch. The invention can also be used for relays that are powered by an alternating current network via rectifiers (one-way, two-way or multi-phase rectifier).
