摘要/Abstract

摘要： 介绍了3起基于气态分解产物测试和局部放电测试发现的典型SF₆全封闭组合电器（GIS）内部潜伏性故障案例。这些案例各有特点：能检出气态分解产物但未检出局部放电信号;未检出气态分解产物但检出局部放电信号;检出气态分解产物的同时也检出局部放电信号。通过解体检查,均验证了设备存在缺陷。因此,气态分解产物和局部放电测试技术在GIS潜伏性故障诊断方面具有广阔的应用前景。

关键词: GIS, 内部潜伏性故障, 气态分解产物测试, 局部放电测试

Abstract: Based on gaseous DPD (decomposition products detection) and PD(partial discharge) detection, three typical cases of internal latent fault cases of GIS are introduced, which have different characteristics: the gaseous DPD result is abnormal but the PD signal is not detected; the gaseous DPD result is normal but the PD signal is detected; the gaseous DPD result is abnormal and the PD signal is detected. The equipment are verified to have defects through disintegration examination. Therefore, gaseous DPD and PD detection technologies have expectable application prospect in the internal latent fault detecting of GIS.

Key words: GIS, internal latent fault, gaseous decomposition products detection, partial discharge detection
