摘要
为了诊断现场气体绝缘组合电器 (GIS)绝缘状况 ,需要对GIS进行现场绝缘试验。阐述了对GIS进行现场交流耐压试验的基本方法 ,并讨论了传统的局部放电测量方法 ,综合分析GIS现场绝缘试验的有效性和存在问题 ,指出交流耐压试验配合灵敏的局放测量是有效的现场试验方法。选择可行的局部放电在线监测系统 。
The Gas-insulated Substation test is very important to find insulation faults in time and increase the reliability of power supply.And the study of test technique of The Gas-insuˉlated Substation is of practical values.In this paper,radical AC voltage withstanding tests and partial discharge(PD)detection are discussed.On the base of comparison of various test methods,the author bring forward that AC voltage withstanding test combining PD detection is more efˉfective in diagnosing defects of GIS.The author also suggests that available PD on line moniˉtoring system should be used to know the state of the running insulation in GIS.
