摘　　要：随着电网日新月异的发展,封闭式组合电器设备(GIS)变电站中采用罐式金属氧化物避雷器近年来得到广泛的应用,作为提高系统运行可靠性和限制电力系统过电压的重要保护设备,其设计技术水平、生产工艺、配件材质要求和运行检测技术在不断的提高和完善。本文介绍了一起220千伏封闭式组合电器内置避雷器的异响故障诊断,通过解体检查,发现了由于GIS避雷器配件材质问题导致GIS避雷器设备故障,并针对该问题提出了若干建议。With the rapid development of the power grid, enclosed electrical equipment （GIS） substations using tank MOA has been widely used in recent years as to improve system reliability and limit over-voltage power systems important protective equipment, its design level of technology, production processes, material requirements and operating accessories detection technology continues to improve and perfect. This article describes the abnormal sound troubleshooting enclosed switchgear 220 kV arrester Built by the disintegration of inspection, found a fitting material due to problems caused GIS GIS arresters arresters equipment failures, and made a number of recommendations for the problem.
