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 vacuum valve includes: an insulation container; a fixed-side electrode including a fixed-side contact, a fixed-side longitudinal magnetic-field coil generating a magnetic field on a surface of the fixed-side contact in an axial direction, and a fixed-side spacer; and a movable-side electrode including a movable-side contact, a movable-side longitudinal magnetic-field coil generating a magnetic field on a surface of the movable-side contact in the axial direction, and a movable-side spacer. The fixed-side longitudinal magnetic-field coil and the movable-side longitudinal magnetic-field coil each include an outer ring portion having an arc shape and a power feeding portion protruding from an end of the outer ring portion. The fixed-side or movable-side contact is brazed to the power feeding portion. The fixed-side and movable-side spacers are made of a material with lower conductivity than materials of the fixed-side and movable-side longitudinal magnetic-field coils, or made of an insulator.
