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。Aiming at the fault of CAM 5.133-592-1W capacitor in series compensation device of a 500 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.
