Abstract

Dieser Leistungsschalter weist eine mit einem isolierenden Medium gefüllte, zylindrisch ausgebildete Löschkammer auf, welche eine entlang einer Längsachse (2) erstreckte Löschzone (1) aufweist. Er weist zudem eine im Zuge einer Leistungsstrombahn angeordnete feststehende Kontaktanordnung (3) und eine bewegliche Kontaktanordnung (4) auf. Ferner ist ein den bei einem Ausschaltvorgang auftretenden, erhöhten Druck des isolierenden Mediums speicherndes Blasvolumen (12) vorgesehen.This circuit breaker has one with an insulating Medium-filled, cylindrical quenching chamber, which an extinguishing zone extending along a longitudinal axis (2) (1). He also assigns one in the course of a Power contact arranged fixed contact arrangement (3) and a movable contact arrangement (4). Further is an increased that occurs during a switch-off process Blowing volume storing pressure of the insulating medium (12) intended.

Es soll ein Leistungsschalter geschaffen werden, bei welchem mit einfachen Mitteln erreicht wird, dass auch stromschwache Lichtbögen sicher gelöscht werden. Dies wird dadurch erreicht, dass in der Einschaltstellung mindestens eine, zwei Auflagestellen (7,8) aufweisende Kontaktbrücke (5) die feststehende Kontaktanordnung (3) und die bewegliche Kontaktanordnung (4) elektrisch leitend miteinander verbindet. Die mindestens eine Kontaktbrücke (5) ist in einer Halterung (6) drehbar gelagert. Die mit der feststehenden Kontaktanordnung (3) zusammenwirkende Seite der mindestens einen Kontaktbrücke (5), wird bezogen auf die Längsachse (2) in radialer Richtung nach aussen, durch eine Kraft beaufschlagt.

Figure 00000001
A circuit breaker is to be created in which simple means ensure that even low-current arcs are reliably extinguished. This is achieved in that, in the switched-on position, at least one contact bridge (5) having two contact points (7, 8) connects the fixed contact arrangement (3) and the movable contact arrangement (4) to one another in an electrically conductive manner. The at least one contact bridge (5) is rotatably mounted in a holder (6). The side of the at least one contact bridge (5) which interacts with the fixed contact arrangement (3) is acted upon in the radial direction outwards in relation to the longitudinal axis (2) by a force.
