In this way, the switch parts inside the cabinet are easily damaged when subjected to external impact. Since the switch parts inside the cabinet are exposed after the cabinet is opened, electric shock accidents are prone to occur, and the door of the cabinet is too close to the door frame after opening. , sometimes it is inconvenient for the staff to operate, and the door does not have a clamping device, so it cannot be closed temporarily

The invention relates to a protection device for a power distribution device of a power system. The protection device comprises a hollow base, a box body fixedly arranged on the top surface of the hollow base, a rubber layer fixedly arranged at the bottom end of the box body, a fixing device arranged in the box body and located on the top surface of the rubber layer, a closing device arranged on the side wall of the box body, clamping devices which are arranged on the box body and the closing device, a dustproof cover fixedly arranged at the top end of the box body and a grid plate fixedly arranged between the dustproof cover and the peripheral edge at the top of the box body. Wire through holes are formed in the side face of the box body, the base and the box body can fix and support thepower distribution device, the rubber layer can insulate and buffer the power distribution device, and the closing device can open and close the box body. The closing device can be temporarily clampedby the clamping devices, the power distribution device can be fixed by the fixing device, dust can be prevented from entering the box body by the dustproof cover, and heat generated by the power distribution device can be conveniently discharged by the grid plate.
Description
technical field [0001] The invention relates to a protection device for power distribution equipment in a power system. Background technique [0002] Power distribution equipment is a general term for high-voltage distribution cabinets, generators, transformers, power lines, circuit breakers, low-voltage switchgear, switchboards, switch boxes, and control boxes in the power system. The protective devices for power distribution equipment are usually only single-layer metal shell cabinet structures with weak protective functions. In this way, the switch parts inside the cabinet are easily damaged when subjected to external impact. Since the switch parts inside the cabinet are exposed after the cabinet is opened, electric shock accidents are prone to occur, and the door of the cabinet is too close to the door frame after opening , Sometimes it is inconvenient for the staff to operate, and the door does not have a clamping device, so it cannot be closed temporarily.
