同塔双回(多回)线路进入等电位方法的研究与应用案例

Entering Equipotential Method for Double Circuit(Multi Circuit)Lines on the Same Tower Research and Application Cases

文章主要针对同塔双回(多回)线路中相和上相进入等电位过程中存在的因受到安全距离、组合间隙、导线对地高度及地形地貌的限制等实际问题,结合实际工作经验,提出一种进入等电位的新方法。文章主要对利用绝缘平梯法进入等电位方法及实际应用情况进行介绍,旨在通过对比和改进提高作业质量和作业效率,进而更深层次地推广、拓展输变电带电作业,提高带电作业化率和供电可靠性。

This article mainly focuses on the practical problems of entering equipotential in the middle and upper phases of double circuit(multi circuit)transmission lines on the same tower due to limitations such as safety distance,combination gap,conductor height to ground,and terrain.Based on one’s own practical work experience,a new method for entering equipotential is proposed.This article mainly introduces the use of insulation ladder method to enter equipotential method and its practical application,aiming to improve the quality and efficiency of work through a series of comparisons and improvements,and further promote and expand live working in power transmission and transformation,improve the rate of live working and power supply reliability.
