WIPO Patent Application WO/2019/132432
Kind Code:
A1
Abstract:
The present invention relates to a movable part of a circuit breaker for a gas-insulated switchgear. The movable part (50) of the present invention includes a puffer cylinder (52), a nozzle (60), a main contact point (64), and the like. Here, an outer rib (62) at the rear end of the nozzle (60) is hooked on a hook rib (58) at a front end of a hook part (56) of the puffer cylinder (52). A chamber guide (54) is provided in the puffer cylinder (52) to prevent the nozzle (60) from being moved. The main contact point (64) is mounted on the outer surface of the front end of the hook part (56). The present invention has the following advantages: the number of parts for constituting a movable part of a circuit breaker is reduced, the number of bolting parts is reduced, and thus, the number of assembling operations is greatly reduced, and a main contact point separation phenomenon due to bolt loosening does not occur.
