Abstract

The invention relates to an electrified repair device for an earthing cable, which is used in the process of repairing the earthing cable in an electrical power system. The electrified repair device comprises a hollow clamp body, wherein an oil cylinder, a hydraulic device and an insulated handle are sequentially connected to the rear end of the clamp body; a piston of the oil cylinder extends into the inner space of the clamp body; a cable pre-tightening chuck is in sliding fit with the front end of the piston; a compressed spring is arranged between the cable pre-tightening chuck and the piston; a puncturing mechanism is arranged in the cable pre-tightening chuck and assembled on the end head of the piston; an insulation hydraulic operation rod is arranged on the lateral surface of the hydraulic device; and a hydraulic reflux device is arranged on the hydraulic operation rod. In the electrified repair device, a puncturing nail can be pushed into the earthing cable safely, quickly and reliably by hydraulic thrust to achieve the effect of temporary earthing.

Description

Technical field [0001] The invention relates to a temporary grounding tool used in the repairing process of a grounding cable of a power system, in particular to a live repairing device for a grounding cable. Background technique [0002] With the development of the economy, the use of high-voltage power cables continues to increase, the voltage level continues to increase, and the cross section continues to increase. The total amount of copper-core insulated wires in the power cable grounding system is increasing, and the cross-section is also increasing. It has become one of the key targets of theft and external damage. The theft or damage of the copper core insulated grounding wire (including grounding wire, coaxial cable, return wire) or damage caused by external force changes the cable grounding system, resulting in potential safety hazards in the operation of the cable line. Therefore, timely repairs are necessary. [0003] After the insulated wire of the cable grounding sys...
