Power transmission line grounding wire horizontal installation device

Abstract

The invention belongs to the field of power transmission line repair and installation grounding wire operating tools, and particularly relates to a power transmission line grounding wire horizontal installation device. The device comprises a supporting body, a telescopic horizontal rod is installed on the top of the supporting body, a fixing sleeve is arranged at the end of the telescopic horizontal rod and connected with a grounding wire installation jig through a connector, a steel wire rope is arranged corresponding to the grounding wire installation jig, the two ends of the steel wire rope are fastened to the inner sides of the tops of wire clamps respectively, and an annealed copper wire is fixed to the outer side of the wire clamp on one side. An original method that a grounding wire is installed in an artificial wire lead-out method is changed into a method that the grounding wire is installed on a power transmission line tower cross beam remotely and horizontally so that personal safety of operating personnel can be effectively guaranteed, labor intensity is lightened, work efficiency is improved, and the method is easy and convenient to operate; the method is suitable for installation of tension tower grounding wires of various voltage levels.

Description

technical field [0001] The invention relates to a device for horizontally installing a grounding wire on a power transmission line, belonging to the field of operating tools for the maintenance and installation of a grounding wire on a power transmission line. Background technique [0002] Grounding wire is a safety tool often used in electric power safety production. Power outage, power inspection, and grounding wire are important technical measures to ensure the safety of transmission line power outage maintenance. An important guarantee for personnel safety and equipment safety. For a long time, the installation of grounding wires has always been the focus of line power outage work. Especially in recent years, with the gradual application of synthetic insulators on straight poles and towers, most of the installation work of grounding wires has been concentrated on tension towers. Therefore, an effective remote The operating device for horizontally installing the groundin...

AI Technical Summary

Problems solved by technology

[0003] The method of horizontally installing grounding wires on existing transmission lines is relatively simple. In the actual maintenance and line reconstruction construction, the installation process of tension tower grounding wires requires workers to climb over the insulator strings and then connect the grounding wires. The risk factor is high. The labor intensity is high and the efficiency is low; at the same time, according to the "State Grid Corporation Electricity Safety Work Regulations (Line Part)", both ends of the operation point need to be connected to the ground wire, so the current method of installing the ground wire on the tension tower is illegal.

Moreover, the higher the voltage level of the pole-climbing work, the greater the distance between the grounding point and the wire, and the more difficult it is for high-altitude workers to complete the installation of the grounding wire. The longer the installation time, the greater the labor intensity, and it is easy to cause muscle fatigue. Hazards, especially tower operators, are prone to high-altitude fall accidents

Due to the long installation time of the grounding wire, the working section is not protected, and other working groups cannot start working, which will affect the work progress and delay the work time
