Abstract

Dieser Leistungsschalter weist mindestens eine zylindrisch ausgebildete Löschkammer (1) auf, welche mit einem feststehenden Kontakt (4), mit einem beweglichen Kontakt (5) und mit einer Löschzone (17) zwischen den beiden Kontakten (4,5) versehen ist. Ein Schaft (7) des beweglichen Kontakts (5) ist mit einem Blasvolumen (9) fest verbundenen, welches festkontaktseitig durch eine von mindestens einem Strömungskanal (16) durchsetzte Isolierdüse (11) abgeschlossen wird. Die Löschkammer (1) weist ein erstes Kompressionsvolumen (21) auf, welches mit dem Blasvolumen (9) und einem zweiten Kompressionsvolumen (23) in Wirkverbindung steht.This circuit breaker has at least one cylindrical trained quenching chamber (1), which with a fixed contact (4), with a movable contact (5) and with an erase zone (17) between the two contacts (4,5) is provided. A shaft (7) of the movable contact (5) is firmly connected to a blowing volume (9), which on the fixed contact side by one of at least one Insulated nozzle (11) through flow channel (16) is completed. The quenching chamber (1) has a first one Compression volume (21), which corresponds to the blowing volume (9) and a second compression volume (23) in Active connection is established.

Es soll ein Leistungsschalter geschaffen werden, bei welchem mit einfachen Mitteln die Beblasung des Lichtbogens mit sauberem SF6-Gas verstärkt ist. Dies wird dadurch erreicht, dass zwischen dem ersten (21) und dem zweiten Kompressionsvolumen (23) ein beweglicher Hilfskolben (22) vorgesehen ist, und dass der Hilfskolben (22) über eine Umlenkung (31) mit dem beweglichen Kontakt (5) verbunden ist.

Figure 00000001
A circuit breaker is to be created in which the blowing of the arc with clean SF 6 gas is reinforced with simple means. This is achieved in that a movable auxiliary piston (22) is provided between the first (21) and the second compression volume (23) and in that the auxiliary piston (22) is connected to the movable contact (5) via a deflection (31) .
