HIGH VOLTAGE HYBRID CIRCUIT BREAKER ACTUATION DEVICE AND CIRCUIT BREAKER THUS EQUIPPED

摘要

The present invention relates to an actuating device providing by a single command the movement between an open position and a closed position of the movable contacts of a dielectric gas interrupt chamber and a vacuum interrupter ( 2) of a hybrid circuit breaker, actuating means (1) ensuring the synchronization of displacement of said movable contacts.According to the invention, said actuating means comprise at least one disk (1A) rotatable about an axis ( 1) perpendicular to said two axes and two connecting rods (1C, 1D) respectively connecting each movable contact to this disk (1A), this disc abutting against a fixed member (1A ") in the closed position of the contacts, the effort exerted by said closing pressure arrangement (3) in this closing position pushing the disc (1A) against this stop member (1A "). / P
