摘　　要：针对目前地下GIS设备进行工频耐压试验的现状,提出了一种采用补偿电抗器和SF6绝缘技术优化设计的新型且小型化的用于500 kV GIS工频耐压试验及局放测试系统,经试验测试新系统的自身局放只有3.2 pC,并且该系统已应用于某地下GIS变电站的工频耐压试验,实践证明此系统完全满足试验需求,且提高了局放的测试精度。In view of present situation of power frequency withstand test for underground GIS equipment,this paper proposed a new small test system of power frequency withstand and partial discharge test for 500 kV GIS based on the optimum design of compensation reactor and SF6 insulation.The partial discharge of the test system only is 3.2 pC.Besides,the test system has already been applied successfully in 500 kv GIS transformer substation.It is proved that the system can fully meet the test requirements and improve the accuracy of partial discharge test.
