摘要
阐述了进行气体绝缘组合电器(GIS)现场交流耐压试验的基本方法,并对局部放电检测诊断内部绝缘的方法进行了讨论。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部放电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,还可以实现实时掌握绝缘运行状态。
The gas-insulated switchgear test is very important to find insulation faults in time and to increase the reliability of power supply. The study of test technique of gas-insulated switchgear 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,it is introduced that AC voltage withstanding test combining PD detection is more effective in diagnosing defects of GIS. Also it is suggested that available PD on line monitoring system should be used for real-time information of the operation insulation in GIS.
