Abstract

Es wird ein Schlatgerät, insbesondere ein Schütz beschrieben das wenigstens eine Doppelkontaktstelle (6,7) aufweist, zu der wenigstens ein Halbleiterventil (4) parallel geschaltet ist. Aufgrund des bei dem Öffnen der Doppelkon­ taktstelle entstehenden Lichtbogens wird das Halbleiterventil (4) angesteuert, so daß der Lichtbogenstrom auf das Halblei­ terventil kommutiert und in seinem Nulldurchgang durch die Halbleiterventil gelöscht wird. Zur Zündung des Halbleiter­ ventiles wird der Lichtbogen ausgenutzt; dabei ist der Steueranschluß über eine Litze mit der Kontaktbrücke ver­ bunden. It becomes a Schlatgerät, especially a contactor described the at least one double contact point (6,7) has at least one semiconductor valve (4) in parallel is switched. Because of the opening of the double con the semiconductor valve (4) driven so that the arc current on the half lead valve commutates and in its zero crossing through the Semiconductor valve is deleted. To ignite the semiconductor valves the arc is used; here is the Ver control connection via a wire with the contact bridge bound.
