摘　　要：在通常情况下,绝缘子沿面闪络电压都是在工频或者雷电冲击电压波形下标定,传统的测量大多能够满足绝缘子的耐压要求。当绝缘子遭受高频高压脉冲作用时,绝缘子表面会发生闪络,从而威胁电力系统安全稳定运行。设计了一款高频高压设备变压器(Tesla变压器)和低容值电容分压器,通过试验检验设计的电容分压器能够适用于特斯拉变压器电压的测量。最后通过Tesla变压器对3种类型的绝缘子进行沿面闪络试验,分析了绝缘子的沿面闪络特性。In general, the flashover voltage along the surface of the insulator is calibrated under the power frequency or the lightning impulse voltage waveform, and most of the traditional measurements can meet the requirements of insulator voltage resistance. When the insulator is subjected to high frequency and high voltage pulse, flashover will occur on the surface of the insulator, thus threatening the safe and stable operation of the power system. This research designed a high-frequency and high-voltage equipment transformer(Tesla transformer) and low capacity capacitance voltage divider. The designed capacitive voltage divider can be used to measure the voltage of Tesla transformer. Finally, the surface flashover characteristics of three types of insulators were analyzed by means of the Tesla transformer.
