Abstract

Dieser Leistungsschalter weist eine mit einem isolierenden Medium gefüllte, rotationssymmetrisch ausgebildete, entlang einer zentralen Achse (2) erstreckte, mit mindestens einer Leistungsstrombahn versehene Löschkammer auf. Ferner weist er eine Kontaktabdeckung (5) und eine von ihr in axialer Richtung beabstandete Isolierdüse (6) auf. Zwischen der Isolierdüse (6) und der Kontaktabdeckung (5) ist ein in ein Heizvolumen (13) einmündender Ringspalt (36) vorgesehen. In der Leistungsstrombahn sind mindestens zwei Abbrandkontakte vorgesehen.This circuit breaker has one with an insulating Medium-filled, rotationally symmetrical, along a central axis (2), with at least one Power chamber provided extinguishing chamber. Furthermore points he a contact cover (5) and one of it in axial Direction spaced insulating nozzle (6). Between the Insulating nozzle (6) and the contact cover (5) is one in one Heating volume (13) opening annular gap (36) is provided. In the power path are at least two erosion contacts intended.

Es soll ein Leistungsschalter geschaffen werden, bei welchem die Vermischung des im Heizvolumen befindlichen kalten Isoliergases mit dem einströmenden Heissgas wesentlich verbessert ist und bei welchem der Druckanstieg im Heizvolumen keine zeitliche Verzögerung erfährt. Dies wird dadurch erreicht, dass der Ringspalt (36) unmittelbar durch einen der Abbrandkontakte abdeckbar ist und in radialer Richtung direkt in das Heizvolumen (13) übergeht.

Figure 00000001
A circuit breaker is to be created in which the mixing of the cold insulating gas in the heating volume with the inflowing hot gas is substantially improved and in which the pressure increase in the heating volume is not delayed. This is achieved in that the annular gap (36) can be covered directly by one of the erosion contacts and merges directly into the heating volume (13) in the radial direction.
