摘要

GW4（A）-40.5DW型户外高压隔离开关在电网中应用广泛

而该型隔离开关导电带存在结构性缺陷

经常出现导电带过热问题。为保证电网安全

针对该型隔离开关导电带结构进行分析

设计出新型导电带并在现场成功实施更换改造。改造后的导电带端部设计为铝质结构并一次焊接成型

将导电带紧固部分设计为对穿螺丝的结构

将导电带软连接设计为铝质结构

解决原有结构性缺陷。

Abstract

GW4（A）-40.5DW outdoor high-voltage disconnectors are widely used in the power grid.There is a structural defect in the conductive strip of this kind of disconnectors

causing a heat conduction problem frequently.To ensure the power grid safety

the internal structure of this conductive strip structure is analyzed

and a new conductive strip is designed

implemented replacement and reform in the scene successfully.Using aluminum in the end of the conductive strip structure and welding it at a time;designing the structure of conductive strip tighten part into blot core structure;using aluminum in the soft conductive strip connection to address the existing structural defect.
