摘要

文中以一起220kV GIS隔离开关故障分析处理及其他同类设备的测试数据为基础

对该类型GIS隔离开关的机械特性进行深入研究

提出了GIS隔离开关装用的弹簧机构机械特性不稳定

应更换为电动机构;同时提出66kV及以上GIS隔离开关出厂机械特性测试及现场机械特性测试时

均应将测试仪的脉冲时间设置为120

00 ms

确保测试仪与站内后台设置的分合闸脉冲时间保持一致

以便全面检查机构箱内电气接线的正确性。为检查测试GIS内隔离开关分合闸是否到位提供了一个行之有效的检测方法。

Abstract

In this paper

based on a fault analysis of 220 kV GIS disconnector and the test data of other similar equipment

the mechanical characteristics of this type of GIS disconnector are studied in depth. It is proposed that the mechanical characteristic of the spring mechanism used for GIS disconnector is not stable

and should be replaced as anmotor-driving mechanism. At the same time

it is proposed that when the mechanical characteristics of the GIS isolating switch and the field mechanical characteristics test are 66 kV or above

the pulse time of the tester should be set to 120

00 ms

so as to ensure that the test instrument is consistent with the time of switching closing pulse in the background

therefore

the correctness of the electrical wi

ring in mechanism box is checked in an all-round way. This is a good method for checking if the disconnector switching closing in the right position.
