Abstract

A gas-insulated circuit breaker (100) disclosed here includes a housing (50) defining a gas volume for a dielectric gas; a nominal contact system and an interruption contact system with a pin (122) and a tulip (124) that they are electrically connectable to and disconnectable from one another along an axis (A). It further has a guiding assembly (150) including a guide sleeve (152) and a guiding member (154) that is coupled to the pin (122); and a gas damping assembly (140) configured to damp a breaking movement of the pin (122) by compressing the dielectric gas in an absorber volume (125). A movable absorption element (142) and the absorber volume (125) are arranged radially inward of the guide sleeve (152).

Description

technical field [0001] The present application relates to gas insulated circuit breakers and methods for breaking electrical connections, and in particular to high voltage gas insulated circuit breakers and methods for breaking electrical connections of high voltage gas insulated circuit breakers. Background technique [0002] Gas insulated circuit breakers are designed to interrupt current by separating two contacts in a dielectric gas with excellent dielectric and arc extinguishing properties, such as sulfur hexafluoride (SF6). A dielectric gas may be contained within the housing. A nominal contact system and an interrupt contact system may be provided in the housing. The nominal contact system can comprise nominal contacts and can optionally establish a rated current path, ie the rated current can be conducted by the nominal contact system. An interrupt contact system may include pins and tulips that selectively establish a power current path. After breaking apart the ...
