摘要
从氧化锌避雷器(MOA)带电检测的方法和原理出发,分析了利用阻性电流测试和红外测温对氧化锌避雷器进行故障诊断的有效性。结合利用带电检测手段发现设备故障的案例,通过停电试验和解体分析证实了避雷器故障的存在,验证了带电测试在避雷器绝缘诊断中的有效性。
The effectiveness of fault diagnosis of Metal Oxide Arrester（MOA） by means of resistance current test and infrared temperature measurement is analyzed based on the method and principles of energized test for MOA.Illustrated with a case of the equipment fault detection with energized test,the arrester fault is confirmed through outage test and disassembly analysis.The effectiveness of energized test for MOA insulation diagnosis is verified.
