摘要
运用超声波法和特高频法相结合的局部放电检测技术,发现和定位了运行中的220 kV站GIS(全封闭组合电器)避雷器气室内部的局部放电,对放电源的类型进行了详细的分析和判断,确定为浮电位部件放电类型。通过停电解体检查证实了检测和分析诊断结果的准确性,为应用带电测试技术积累了经验。
The partial discharge （PD）detection was performed to a 220 kV GIS by the UHF sensing method and the ultrasonic sensing method. A partial discharge was found and located in the arrester chamber. Based on the analysis of the PD signal pattern, a PD of floating part was determined. The detection and diagnosis results were confirmed by the afterward maintance, which provided a valuable sample for the GIS PD on-line detection.
