Abstract
The utility model relates to an anti-falling device of a ground wire, comprising a ground wire clamp. The ground wire clamp comprises a U-shaped clip and a ground wire rod. A fixed seat is arranged on the ground wire rod. The fixed seat comprises a main fixing piece and a clamping piece. The fixed seat is detachably connected with the round wire rod through the clamping piece. The main fixing piece is provided with a threaded hole. A screw is arranged in the threaded hole. A threaded part 1 matching with the threaded hole is arranged on the upper part of the screw. A threaded part 2 matching with the threaded hole is arranged on the lower part of the screw. An operational rod is fixed at the lower part of the screw. The anti-falling device has the beneficial effects that, after the anti-falling device of the ground wire is adopted, the ground wire is prevented from falling off from the lead when electrical equipment such as a breaker or an isolation switch is replaced at a power plant and a transformer station, hence, reliable grounding is ensured and personal safety of the working personnel is ensured.
