Study of Insulation Device of Fixed Drainage Line and Jumper for Live Working of 10kV Distribution Line

doi:10.11985/2017.06.004

Abstract

Abstract:

In the 10kV distribution line live work, due to the tower and the equipment without a suitable fixed position, workers disassemble and remove the drain line and disconnect jumper easily lead to short circuit or ground, and lead to security incidents. Firstly, in this paper, the shortcomings of the existing methods are analyzed and discussed in detail, and an insulation fixture is designed and developed. It consists of telescopic insulated base, insulated pole and fixture. Through the field application shows that the device versatility, easy to operate, safe and reliable. It can solve the replacement of 10kV charged column device, and the jumper no fixed location problem. It greatly improves the work efficiency and safety, shortens the user’s power outage time, improves the power supply reliability, at the same time provides the strong technical support for power grid operation and continuity of power supply. It has a high value in popularization and application.

Key words: Distribution lines, live working, drainage line, jumper
