HYBRID GAS SWITCH TYPE suppressant for switchgear gas-insulated switchgear

摘要

1. A hybrid-type gas circuit breaker for extinguishing switchgear gas insulated switchgear comprising a fixed part (10) comprising an arcuate contact portion (13); a movable part (20) comprising a cylinder (21), the piston (22) mounted within the cylinder (21), a wind box (24) and the chamber (25) of thermal expansion formed by a partition wall (23) and a working electrode (26) extending through the interior of the piston (22) and the cylinder (21) and comprising an arcuate contact portion (26a), which can be provided close to the arc contact portion (13) of the fixed part, the one side surface of the partition wall (23) is equipped with a movable valve (30), comprising adhering portion (31) movable drop ohm pressure and adjacent to the dividing wall (23) and a movable part (32) extending from the adhering portion (31) and permit the passage therethrough of the working electrode (26) and opening and closing the chamber (25) of the heat rasshireniya.2. The switch of claim 1, wherein the adhering portion (31) forming the movable valve (30) has one or more outlets (31a), letting out the arc extinguishing gas from the wind box (24), wherein each discharge opening (31a ) connected to a nonreturn valve (31b), a a movable part (32) is formed by the through hole (32a) .3. Switch according to claim 1, characterized in that the chamber (25) is equipped with thermal expansion outlet (25a), which produces an arc extinguishing gas to the fixed part (10) as one surface of the chamber (25) of thermal expansion and the outlet (25a ) fitted with a check valve (25b), and provides support tube (25c), made from slipping
