摘要
分析了封闭式组合电器(GIS)发生闪络的原因,建立了闪络过程的模型,并采用超声波的方法对故障点进行检测和定位,并在实验室对550 k V GIS设备在耐压过程中进行尖端和气隙闪络放电试验,利用该方法对故障点进行定位,验证了该模型和方法的有效性。
The cause of flashover emergence is discussed and the flashover process model is established. Ultrasonic detection method is used to test the flashover fault and locate fault spot. Through an actual 550 kV GIS AC withstand voltage test, the method proposed in this paper is utilized to detect the inside point and gas gap flashover. The result verifies that the proposed model and the test method are feasible and effective in the handover stage test.
