Problems solved by technology
Because the chassis car successfully uses the electromagnetic clutch as the clutch part for power transmission, this chassis car makes full use of the advantages of small size and simple structure of the electromagnetic clutch, which can significantly reduce the required space and completely solve the problem of the chassis car's carrying capacity and space. Contradictions between restrictions, so as to realize the electrification of circuit breakers, especially the 40.5kV voltage level, creates conditions for automatic control, and then solves the technical problem that the 40.5KV circuit breaker chassis has been unable to implement automatic operation.

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.
Description
technical field [0001] The invention relates to a circuit breaker chassis vehicle in a power system, in particular to a circuit breaker electric chassis vehicle. Background technique [0002] In the existing insulated switchgear, in order to enable the vacuum circuit breaker to conveniently realize the function of advancing and withdrawing (propelling refers to advancing from the test position to the working position, and withdrawing refers to withdrawing from the working position to the test position), a chassis is generally used The vehicle carries the vacuum circuit breaker, and moves forward or backward on the track in the switch cabinet through the driving wheels installed on the chassis vehicle. In order to realize the movement of the chassis car in the switch cabinet, a screw rod can be set on the chassis car, and a screw nut fixed on the chassis frame is sleeved on the screw rod, and the handle is put on the end of the screw rod, and the screw rod is rotated to make ...
