摘要
部分油浸式电流互感器在运行中会出现氢气含量超标,可能引起设备故障,危及电网安全运行。通过一起油浸式电流互感器故障调查,结合故障设备油色谱和介损试验结果的特点,分析了氢气含量超标引起油浸式电流互感器故障的原因,并提出了反事故措施。
Over-range hydrogen on oil-immersed current transformer would cause equipment failure which will endanger the safe operation of power grid. The paper takes a failure investigation of oil immersed current transformer as example. Analysis about the reason of over-range hydrogen on oil-immersed current transformer based on oil chromatographic tests and dielectric loss tests. Some treatment methods to prevent similar accident from happening are provided.
