摘要： A switching device for a medium-voltage electrical circuit including: a frame; a vacuum circuit breaker including a fixed electrode relative to the frame and a mobile electrode; an elastic member; and an actuating lever connected to the mobile electrode via the elastic member, The actuating lever is movable between an open position in which the electrodes are separated by an open distance, and a closed position in which the electrodes are in contact. A passage of the actuating lever from the open position to the closed position defines a displacement stroke, greater than the open distance such that the elastic member is compressed when the actuating lever passes from the first position to the second position. The switching device includes at least one removable spacer arranged between the frame and the fixed electrode.

摘要： A circuit breaker includes a frame and first, second and third single-phase vacuum interrupters and first, second and third magnetic actuators connected to respective single-phase vacuum interrupters. Each of said magnetic actuators is configured to receive an open or close signal and in response, actuate the respective vacuum interrupter connected thereto into an open or closed circuit condition. Each magnetic actuator includes a fixed core, a plurality of permanent magnets surrounding the fixed core, and a movable core received within the fixed core. A controller is connected to each of the first, second and third magnetic actuators and generates the open or close signal to a respective magnetic actuator to open or close one or more of the first, second and third single phase interrupters.

摘要： A switching apparatus including one or more electric poles. For each electric pole, the switching apparatus includes a first pole terminal, a second pole terminal, a ground terminal, and a plurality of fixed contacts spaced apart one from another. For each electric pole, the switching apparatus further includes a movable contact and a vacuum interrupter. The movable contact is reversibly movable about a corresponding rotation axis. The vacuum interrupter includes a movable arc contact reversibly movable along a corresponding translation axis. For each electric pole, the switching apparatus further includes a motion transmission mechanism operatively coupled to a contact shaft solidly coupled to the movable arc contact. The motion transmission mechanism is actuatable by the movable contact to cause a movement of said movable arc contact along said translation axis, when said movable contact moves about said rotation axis.
