Cable end grounding wire device

Abstract

The invention provides a cable end grounding wire device which relates to a safety protection device in electrical cable maintenance. The device comprises a grounding wire, a support frame and an insulation wire clamping head device, wherein the insulation wire clamping head device is movably connected with the support frame; the insulation wire clamping head comprises an insulation rod, a wire clamping head and an opening and closing mechanism. The wire clamping head comprises a body and a clamping block, and the clamping block is arranged in a notch of the C-shaped body. The opening and closing mechanism comprises a spring, a guide rod, a soft cable, a pull rod and a crank mechanism. The body is connected with the insulation rod through an elbow. The guide rod is fixed on and connected with the back surface of the clamping block. The spring is arranged on the guide rod between the clamping block and the body. The guide rod extends into the elbow, and then is fixed on and connected with the pull rod in the insulation rod through the soft cable. The crank mechanism is arranged on the lower part of the insulation rod, and comprises a crank type wrench and a wrench bracket. The wrench bracket is arranged outside the insulation rod. The middle part of the crank type wrench penetrates through the insulation rod, and is hinged with the pull rod. A straight handle end is hinged with the wrench bracket to form a fixed fulcrum. The grounding wire is connected with the body. The invention has the advantages of skillful concept and high reliability.

Description

technical field [0001] The invention relates to a safety protection device for power cable maintenance, in particular to a cable head grounding wire device for maintenance of user cables. Background technique [0002] In the normal power line and user power equipment maintenance work, it is often necessary to disassemble the connection joint between the power cable and the overhead line. At this time, safety measures should be taken on the power cable head (cable lug). The reason is that although the cable head at the disconnected user end has lost power, many users have their own generators. These disconnected cable ends will be charged, and then endanger the life safety of maintenance personnel. Because most of the power cable heads entering the user's place are arranged in a vertical direction, they cannot bear gravity, and the ground wire has a certain weight, making it difficult for the cable lug to support the weight of the ground wire. For this reason, when running ...

AI Technical Summary

Problems solved by technology

At present, the ordinary grounding wire hanging rod has a horizontal opening, which cannot adapt to such a use environment, and it is impossible to add a grounding wire to the power cable head with the wire head and the wire nose facing upwards.
