High voltage earthing wire with telescopic short-circuit wires

Abstract

The invention provides a high voltage earthing wire with telescopic short-circuit wires. The high voltage earthing wire comprises a plurality of groups of earthing assemblies, an earthing wire, a confluence clamp and an earthing terminal, wherein each group of earthing assemblies comprises an insulating operation rod, a wire clamp installed on the top of the insulating operation rod and a short-circuit wire expansion piece; one end of the earthing wire is connected to the earthing terminal, and the other end of the earthing wire is connected with the short-circuit wires through the confluenceclamp; the other end of each group of short-circuit wires is connected to the wire clamp, and the short-circuit wire expansion piece is used for accommodating the short-circuit wires. According to thehigh voltage earthing wire with the telescopic short-circuit wires designed in the invention, the lengths of the short-circuit wires can be independently chosen when the short-circuit wires are used,and the problem that the lengths of the short-circuit wires are insufficient when non-standard type wires are repaired is effectively solved.

Description

technical field [0001] The invention relates to the technical field of high-voltage grounding wires, in particular to a high-voltage grounding wire with a retractable short-circuit wire. Background technique [0002] The high-voltage grounding wire is composed of wire terminal clamps, short-circuit wires, confluence clamps, grounding wires, terminal lugs, grounding terminal clamps or temporary grounding electrodes and grounding operating sticks. The length of the 110kV high-voltage grounding wire insulation operation rod is 2m, and the length of the short-circuit wire is generally about 1.5m. [0003] The high-voltage grounding wire is mainly used to prevent electrostatic induction electric shock or false closing of the nearby charged body to ensure safety. The use method is to connect the grounding clip first, and then connect the electric clip. The phenomenon of grounding clips, such as 10kV line maintenance, the wire is an insulated conductor, and the normal ground is at...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that the short-circuit part of the ground wire is not suitable for the work site, after many discussions, the present invention aims to provide a high-voltage ground wire with a retractable short-circuit wire, which appropriately increases the diameter of the short-circuit wire without lengthening the lock The state is in the normal state. After being stretched, the length of each of the three short-circuit wires can reach more than 2 meters, which can effectively solve the problem that the grounding wire cannot be effectively used for non-standard line maintenance.
