Abstract (en)
[origin: EP0369844A1] The locking mechanism according to the invention comprises two levers (4a, 4b) which act respectively on two tappets (2a, 2b) for activating the breakers (1a, 1b) of an inverter-contactor. Each of these levers, hinged about a fixed axis (5a, 5b) comprises a roller (6a, 6b) applied to the profile of a rotating cam (7) by a spring (9a, 9b). This cam (7) can go from a locked position of automatic action in which it authorises the closing of the breakers (1a, 1b) by keeping the levers (4a, 4b) away from the tappets (2a, 2b), to a tripped position in which the lever (4a, 4b) acts on the tappets (2a, 2b) to keep the breakers (1a, 1b) in the open position. <??>The tripping of this mechanism can be ensured by a trigger activated by one or more default detection relays. <IMAGE>
