摘要
针对特高频局部放电检测在气体绝缘全封闭组合电器(Gas Insulated Switchgear,GIS)测试中存在的问题,对现场典型案例进行研究,分析相关案例在资料检查、仪器和工具准备、测试点选择、测试操作、典型图谱对比、故障点精准定位等环节中可能出现的问题,提出了特高频局部放电检测要领,提高了局部放电检测的准确性,对保证电网安全运行具有重要意义.
Abstract
In allusion to the problems encountered in the testing of gas insulated switchgear(GIS)with ultra-high frequency partial discharge detection,the typical on-site cases are studied,and the problems that may arise in processes,such as data examination,preparation of instruments and tools,test point selection,testing operation,comparison with typical waveforms and precise fault lo-cation,are analyzed.The key points of ultra-high frequency partial discharge detection are proposed,the accuracy of partial dis-charge detection is improved,which is of great significance to ensure the safe operation of power grid.
