Sparkproof closing equipment for power grid

The invention relates to the technical field of closing equipment, in particular to spark-proof closing equipment for a power grid, and the spark-proof closing equipment comprises a wiring mechanism which is fixedly connected to one side of a closing equipment body and is provided with the wiring mechanism, and the purpose of fixing a cable is achieved through the arrangement of a clamping block, a spring and a built-in thread in the structure. The cable is limited through combination of the spring and the clamping block, one end of the cable is in threaded connection with the wiring socket through the built-in thread, the friction force between the wiring socket and the cable sheath is increased through the rubber layer, the cable is prevented from slipping off, and the insulating coating is arranged on the inner wall of the wiring socket, so that the cable is prevented from slipping off; and the insulating necklace is arranged at one end of the wiring socket, so that the risk of electric leakage is greatly
