| 摘 要： | 气体绝缘组合电器(简称GIS)在输变电系统中的应用越来越广泛,为了更好地保证GIS在运行中的稳定性,本文研究了三相共筒式GIS在运行中常见的故障类型,根据具体的试验条件,设计了三种典型的绝缘缺陷模型,并采用超高频法(UHF)对存在故障的GIS进行了局部放电检测,分析了几种绝缘缺陷放电的典型图谱,为GIS的稳定运行和故障的及时检修提供了依据。

| Abstract: | Gas insulated switchgear（GIS） is widely used in power transmission system. In order toensure the stability of GIS in operation better, the paper studies the common fault types in theoperation of three-phase-common GIS. Based on the test conditions, three typical insulation defectmodels are designed, and the UHF method is applied to detect the partial discharge existing inGIS. Typical spectrums of insulation defects partial discharge are analyzed, which will provide abasis for the future of GIS stable operation and timely maintenance of faults. |
