ELECTRIC CHASSIS VEHICLE FOR CIRCUIT BREAKER

摘要

An electric chassis vehicle for a circuit breaker comprises a static frame and a movable frame (9) moving relative to the static frame. A lead screw (8) is mounted on the static frame, and a lead screw block (7) fixed to the movable frame (9) is assembled on the lead screw (8). A motor assembly (1) is also mounted on the movable frame (9). Rotation of the motor assembly (1) is transferred to the lead screw (8) through a transmission mechanism so as to drive the lead screw block (7), the movable frame (9), and the motor assembly (1) to move along an axial direction of the lead screw (8). An electromagnetic clutch is mounted between the motor assembly (1) and the transmission mechanism. The electric chassis vehicle for the circuit breaker is of a simple structure and small in size, and has a great carrying capacity.
