摘要： The movable portion (35) of a vacuum circuit-breaker comprises a circular spring (46) sliding on an outer bearing surface (41) in most positions, that is suitable for entering a recess (40) on relaxing in order to define a maximally open position for the vacuum circuit-breaker in which locking is thus provided. The movable portion (35) may be made up of two sections (38, 39), of which one, made of copper, is a very good electrical conductor, and is directed towards the stationary contact (37) and receives a connection element for connection to an outside electrical circuit; the section (38) may be made of steel in order to promote sliding of the spring without wear.

摘要： A locked state for a movable part (11) of switchgear is created by deflected spring wires (15) entering a recess (12). Said device is reversible and has the advantage of being safe since it is completely passive, and it improves the dynamics of the movement of the movable part in particular by damping impacts when entering the abutment state. The invention can be applied to the drive rod of a vacuum circuit-breaker.
