摘要
对一起500 kV电容式电压互感器(CVT)运行中二次电压值异常的故障做了简要分析。介绍了CVT故障发现和分析的全过程。通过二次电压的变化及停电试验结果对缺陷进行了分析,经过对故障CVT解体验证了分析的正确性。同时,对运行CVT的状态监测提出了具体措施。
This paper provides a brief analysis of a fault of secondary voltage abnormality in a 500 kV capacitor voltage transformer, introduces the whole process of CVT fault detection and its a-nalysis. Based on secondary voltage abnormality and test results afterward, the defect has been analyzed; after CVT disassembled, the analysis correctness had been verified . At the same time, specific measures for monitoring CVT operating status have been proposed.
