摘要

针对500 kV某乙线线路串联补偿装置中的CAM 5.133-592-1W电容器出现故障

导致串补不平衡电流保护动作

串补重投不成功

通过对电容器设备解体分析其故障原因

指出电容器漏液致使第1串联段的12个元件出现击穿现象是主因

结合日常巡视和定期维护提出了相应预防措施

为同类设备的安全可靠运行提供出指导性的建议。

Abstract

Aiming at the fault of CAM 5.133-592-1W capacitor in series compensation device of a500 kV line

which results in unsuccessful reclose of series compensation after the action of imbalance current protection due to the fault

the main causes of such fault are the breakdown occurred in 12 elements in the first series section due to liquid leakage of capacitor through disassembling the fault capacitor.The corresponding preventive measures are proposed with combination of routine patrol and periodic maintenance

which provides instructive suggestion to the safe and reliable operation of similar type of equipment.
