Abstract (en)
[origin: EP0817228A2] The circuit breaker switch has a contact zone that is filled with an insulation gas SF6 and has a metallic contact pin Ä3Ü that normally passes through a nozzle section and into a contact bush Ä8Ü. The contact region is within a cover Ä5Ü and this is within an isolating cylinder Ä12Ü. When the contact cylinder retracts the pin moves to break contact. A gap exists Ä36Ü and in this region effective mixing of the hot and cold gases takes place.
