Abstract:
Drive mechanism for the synchronous operation of a plurality of vacuum circuit breakers (35). It comprises energy storage means (6), conversion means (37) for converting energy stored in the energy storage means (6) into an operation of switching off the vacuum circuit breakers (35) and for switching on the vacuum circuit breakers (35), in which latter process energy is simultaneously stored in the energy storage means (6). The conversion means (37) comprise first transfer means which can move substantially in a first direction and second transfer means which can move substantially in a second direction. The conversion means also comprise at least one connecting rod (4, 4'), which on one side (23, 23') is rotatably secured to the first transfer means and on a second side (22, 22') is rotatably secured to the second transfer means. The drive mechanism also comprises a trip mechanism which interacts with the drive mechanism and a disconnector drive mechanism (70) for the simultaneous operation of disconnectors (73).

Abstract:
Latching device for a circuit breaker comprising - a manual operating toggle (2) which is moveable arranged between an OFF-position and an operation-readiness position, - a moveable contact (52) and a fixed contact (51), wherein the moveable contact (52) is adapted to open and close the main circuit of the circuit breaker, - an energy storage mechanism which stores an actuating force of the toggle (2) when the toggle (2) is moved from the OFF-position to the operation-readiness position and is adapted to exert the stored force to the moveable contact (52) to close the main circuit of the circuit breaker, characterized in that the latching device further comprises a removable retention lever (4) for preventing the movement of the moveable contact (52) into a closing position if the energy storage mechanism exerts the stored force to the moveable contact (52).
