Abstract

Dieser Leistungsschalter weist eine Leistungsstrombahn auf und eine mit einem isolierenden Medium gefüllte Löschkammer (1). In der Leistungsstrombahn ist je ein bewegliches (2) und feststehendes Kontaktstück (3) angeordnet. Ferner ist in der Löschkammer (1) mindestens eine zumindest zeitweise durch Strom beaufschlagten Blasspule (22) vorgesehen und ein den bei einem Ausschaltvorgang auftretenden, erhöhten Druck des isolierenden Mediums speicherndes Blasvolumen (9).This circuit breaker has a power current path and an extinguishing chamber (1) filled with an insulating medium. There is one movable (2) and one fixed in the power path Contact piece (3) arranged. Furthermore, in the Extinguishing chamber (1) at least one at least temporarily Current-applied blow coil (22) is provided and one at a switching off occurring, increased pressure of the isolating medium storing blowing volume (9).

Es soll ein Leistungsschalter geschaffen werden, bei welchem mit einfachen Mitteln ein zu hoher Druckanstieg im Blasvolumen vermieden wird. Dies wird dadurch erreicht, dass die mindestens eine Blasspule (22) ganz oder teilweise kurzschliessbar ausgebildet ist, und dass Mittel vorgesehen sind, welche dieses Kurzschliessen ermöglichen.

Figure 00000001
A circuit breaker is to be created in which an excessive pressure rise in the blowing volume is avoided with simple means. This is achieved in that the at least one blow coil (22) is designed to be fully or partially short-circuited and that means are provided which enable this short-circuiting.
