Abstract

Es wird eine Flachlöschkammer 36 für einen Lasttrennschalter 10 mit schwenkbar gelagertem Schleppmesser 30 beschrieben. Diese besteht aus einem einen Schleppmesserkontakt 38 aufnehmenden Flachgehäuse, das seitliche Löschplatten 42 umfaßt, die aus Löschgas abgebendem Material bestehen und zwischen sich einen Löschspalt definieren. Der Löschspalt ist durch einen sich über einen Schleppmesserschwenkbereich erstreckenden, in der Schwenkebene des Schleppmessers 30 betrachtet schmalen Löschkanal 34 gebildet, wobei die Löschplatten 42 vorzugsweise durch mehrere, insbesondere entlang des schmalen Löschkanals 34 vorgesehene Verbindungselemente 52 so abgestützt und/oder fixiert sind, daß der Querschnitt des Löschkanals 34 unabhängig von dem jeweiligen Abschaltstrom und dem jeweiligen Gasdruck in dem Flachgehäuse zumindest im wesentlichen gleich bleibt.
