| 摘 要： | 交流耐压试验是考核电力设备绝缘性能最直接、最有效的方法。介绍了在1 000 kV南阳开关站对特高压电抗器进行外施交流耐压试验的情况,利用串联谐振的方法进行特高压电抗器的交流耐压试验,通过对补偿电容器和电抗器的合理组合,可以将试验频率控制在工频45～65 Hz之内,满足试验要求。试验所需设备少,对试验电源容量要求不高,适合在现场使用。

| Abstract: | AC voltage withstand test is the most direct and effective method to judge the Insulation Performance of Electrical Equipments.In this paper,an AC voltage withstand test of ultra high voltage(UHV for short) shunt reactors at 1 000 kV AC Nanyang switch-gear station was conducted.The test frequency could be limited within 45 ～65 Hz by adopting serial resonance method and properly combining compensating capacitors and reactors.This test needs less test devices and lower power supply capacity,thus to be suitable for field AC voltage withstand test of UHV Shunt Reactors. |
