安荣220kV变电站110kV西母气室异常声响分析

Abnormal Sound Analysis of Anrong 220kV Substation 110kV West Bus Chamber

GIS组合电器具有结构简单、紧凑、体积小、灭弧能力强等优点,被广泛应用于电网。本文介绍了一例因母线气室声响异常引起专业人员注意,进而进一步观察检测,发现的重大故障隐患及故障的诊断分析与处理,起到了及时避免该设备放电导致停电的重要作用。同时也表明了局部放电测试技术和SF6分解产物检测技术的联合使用是运行中GIS设备故障检测的有效手段。

The GIS combined electrical apparatus has advantages of simple structure, compact, small size and strong arc-quenching ability, so it is widely used in the power grid. This article describes a case of significant hidden fault found through abnormal sound of bus chamber and the diagnosis analysis and treatment of fault, avoiding the power failure caused by discharge of the device. Also this article suggests that the combination of partial discharge test technology and SF6 breakdown products detection technology is the effective tool for fault detection of GIS equipment in operation.
