Problems solved by technology

[0002] When high-voltage equipment such as substations, transmission lines, and distribution lines are powered off for maintenance, in order to ensure the safety of the staff, it is necessary to install a grounding wire on the side where the incoming power may come. The tension and contraction force is relatively large, and a large force is required to pull it apart, which is not conducive to efficient work and is easy to damage the high-voltage line

Abstract

The invention discloses a high-voltage ground wire easy for assembling and disassembling. The ground wire comprises an operating head and an operating supporting part which is detachably connected with the operating head; the operating head comprises a cable clip main body, a connecting piece, an upper clamping head and a lower clamping head; the upper clamping head is fixedly connected with the top of the cable clip main body through the connecting piece; the bottom of the lower clamping head is provided with a pin; the cable clip main body is provided with a through hole which matches with the pin and the pin passes through the through hole to the outside and is provided with a suspension ring; the pin is sleeved by a spring; the operating supporting part comprises an insulated support bar; the insulated support bar is provided with an insulated operating bar; the insulated operating bar is provided with an insulated draw hook bar; the top of the insulated draw hook bar is provided with a draw hook which matches with the suspension ring; the upper end of the insulated support bar is provided with two sector gears which are symmetrically arranged; the top of the insulated operating bar is provided with a bidirectional gear rack which matches with the section gears; each of the section gears is provided with a clamp arm which matches with the cable clip main body. It is convenient to assemble the ground wire on high-voltage lines; and high-voltage lines will not be damaged when the ground wire is disassembled; the ground wire is simple and convenient to use, and is safe and practical.

Description

technical field [0001] The invention mainly relates to the technical field of electric power safety, in particular to a high-voltage grounding wire that is easy to install and disassemble. Background technique [0002] When high-voltage equipment such as substations, transmission lines, and distribution lines are powered off for maintenance, in order to ensure the safety of the staff, it is necessary to install grounding wires on the side where the power may come in. The part of the grounding wire connected to the high-voltage equipment often uses spring clips. The tension and contraction force is relatively large, and a large force is required to pull it apart, which is not conducive to efficient work and is easy to damage the high-voltage line. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides a high-voltage grounding wire that is easy to install and disassemble. It is convenient to install the operatio...
