Abstract

A gas insulated circuit breaker (100) disclosed herein includes: a housing (50) defining a gas space for a dielectric gas; a nominal contact system; and an interrupting contact system having a pin (122) and a tulip ( 124), they can be electrically connected and disconnected from each other along the axis (A). The gas insulated circuit breaker (100) further has a pilot assembly (150), which includes a pilot bushing (152) and a pilot member (154) coupled to the pin (122); and a gas damming assembly (140), which It is configured to dampen the breaking movement of the pin (122) by compressing the dielectric gas in the absorber space (125). The movable absorption element (142) and the absorber space (125) are arranged radially inside 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 flow 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 in the housing. The nominal contact system and the break contact system may be provided in the housing. The nominal contact system may include nominal contacts and may selectively establish a nominal current path, ie the nominal current may be conducted by the nominal contact system. The break contact system can include pins and tulips that can selectively establish a power current path. After the breaking c...
