GAS-INSULATED CIRCUIT BREAKER AND A METHOD FOR BREAKING AN ELECTRICAL CONNECTION

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). 本文公开的气体绝缘断路器(100)包括：壳体(50)，其限定用于介电气体的气体空间；标称接触系统；以及中断接触系统，其具有销(122)和郁金香形件(124)，它们可沿着轴线(A)彼此电连接和脱开。气体绝缘断路器(100)进步具有导引组件(150)，其包括导引套管(152)和联接到销(122)的导引部件(154)；以及气体阻抑组件(140)，其构造成通过压缩吸收器空间(125)中的介电气体而阻抑销(122)的断开运动。可动吸收元件(142)和吸收器空间(125)布置在导引套管(152)的径向内侧。
