摘要

文中基于一起220 kV GIS隔离开关气室异响，阐述了隔离开关动作原理、拨叉结构，设备解体后发现传动机构拨叉与轴销处有明显的电弧烧伤痕迹，其间等电位接触弹簧消失不见。结合Comsol有限元仿真分析，推断接触弹簧变形、损坏，导致拨叉与轴销无法可靠等电位连接，产生悬浮电位，造成气室内电场畸变，进而击穿放电发出异常声响。据此，开展同型号隔离开关隐患排查，更换拨叉接触弹簧，加强运行巡视等运检措施，为类似缺陷的检测和处理提供了经验参考。

Abstract

Based on the abnormal sound in the gas compartment of 220 kV GIS disconnector，the operation principle and the structure of the shifting fork of the dsiconnector are described. It is found after disassembly of the equipment that obvious arc ablation marks at the shifting fork and shaft pin of the drive mechanism are founded，and the equipotential contact spring between them is disappeared. It is inferred in combination with Comsol finite element simulation analysis that the contact spring is deformed and damaged，resulting in the unreliable equipotential connection between the shifting fork and the shaft pin，then generating suspension potential，causing electric field distortion in the compartment，breakdown discharge and abnormal sound. Based on this，the hidden trouble of the same type of disconnector and such measures as replacement of the contact spring of the fork and intensification of inspection measures are developed so to provide experience and reference for the detection and treatment of similar defects.
