Abstract

Bekannt sind Leistungsschalter mit sogenannten Autokompressionskammern, bei denen die Kontakte in einer Schaltkammer beim Schaltvorgang mit einem Löschgas beströmt werden. Gemäß der Erfindung hat die Autokompressionskammer (100) wenigstens eine zusätzliche Öffnung (107, 207, 307), durch die das Gas während des Ausschaltvorganges in das Volumen (100; 110, 120) der Schaltkammer (10) einströmbar ist. Damit wird der bisher notwendige Aufwand zur Bevorratung des Gases wesentlich vermindert.

Circuit breakers with so-called auto-compression chambers are known, in which the contacts in a switching chamber are supplied with an extinguishing gas during the switching process. According to the invention, the autocompression chamber (100) has at least one additional opening (107, 207, 307) through which the gas can flow into the volume (100; 110, 120) of the switching chamber (10) during the switch-off process. This significantly reduces the effort previously required to store the gas.
