Description

Bei elektrischen Anschlußapparaten mit Induktionsapparat pflegt man der Unter,1· brechungsstelle des zu dem Induktionsapparat gehörenden Wagnerschen Hammers einen Kondensator parallel zu schalten, um durch die funkenlöschende Wirkung des Kondensators die Stromunterbrechungen an dem Wagnerschen Hammer rasch und gleichmäßig zu gestalten.In electrical connection devices with induction apparatus to maintain the sub, 1 · refraction point of the belonging to the inductor Wagner hammer to switch a capacitor in parallel to make rapidly and uniformly to the power interruptions to the Wagner's hammer by the arc-extinguishing effect of the capacitor.

ίο Bei den bekannten Einrichtungen dieser Art entlädt sich in dem Augenblick, in welchem der Primärstromkreis des Induktionsapparats durch Öffnen des in diesem Stromkreis angeordneten Schalters unterbrochen wird, an der Unterbrechungsstelle dieses Schalters die durch die Unterbrechung in der im Stromkreis liegenden Drahtwicklung, insbesondere in der Primärwicklung des Induktionsapparats erzeugte Extraspannung.ίο In the known devices of this type discharges at the moment in which the primary circuit of the induction apparatus by opening the circuit in this circuit arranged switch is interrupted, at the point of interruption of this switch by the interruption in the wire winding lying in the circuit, especially in the primary winding of the induction apparatus generated extra tension.

Dadurch entsteht ein Lichtbogen, welcher den aus Gründen des erforderlichen engen Zusammenbaues kleinen und, wenn kostspielige Bauart vermieden werden soll, nur einfach ausgeführten Schalter durch Verbrennen seiner Kontaktstücke beschädigt.This creates an arc, which for reasons of the required tight assembly small and, if costly construction is to be avoided, only simply implemented switches by burning its contacts damaged.

Dem ist bei der neuen Schaltungsanordnung abgeholfen, die in einem Ausführungs:- beispiel in der Abbildung schematisch wiedergegeben ist.This is remedied with the new circuit arrangement, which in one embodiment: example is shown schematically in the figure.

Gemäß der Erfindung ist der Kondensator c zwischen die Stromzuführung zum Schalter« und die nicht mit dem Schalter verbundene Zuleitung des Wagnerschen Hammers b geschaltet. Infolgedessen ist der Kondensatorc, wenn der Schalter« geschiossen ist, durch den Schalters dem Wagnerschen Hammer und, wenn der Schalter« geöffnet ist, durch den Wagnerschen Hammer b der Unterbrechungssbelle des Schalters a parallel geschaltet. Dadurch ist es ermöglicht, den ohnedies für den Wagnerschen Hammer erforderlichen Kondensators auch zur Funkenlöschung an dem Schalter α zu verwenden, ohne daß es irgendwelcher zusätzlicher Einrichtungen hierzu bedürfte!.-According to the invention, the capacitor c is connected between the power supply to the switch and the supply line of Wagner's hammer b that is not connected to the switch. As a result, when the switch is closed, the capacitor c is connected in parallel through the switch to the Wagner's hammer and, when the switch is open, through the Wagner's hammer b to the breaker of the switch a . This makes it possible to use the capacitor, which is required anyway for Wagner's hammer, for spark quenching on the switch α without any additional equipment being required!
