摘要
针对220 kV TEMP-220SU型CVT三相输出电压不平衡问题,通过对故障CVT进行高压试验和设备解体分析,发现C2电容器元件击穿导致二次输出电压降低是CVT故障的主要原因,最后结合日常巡视和高压试验方法提出了相应预防措施,为同类设备的安全可靠运行提供指导性的建议。
As for imbalance of three-phase output voltage of 220 kV TEMP-220SU capacitor voltage transformer （CVT）. Through high voltage test and disassembly analysis for the faulty CVT, the main reason of CVT fault is the reduction of the secondary output voltage which caused by breakdown of C2 capacitor element. Finally, based on daily patrol and high voltage test method, corresponding preventive measures are proposed; and the instructive suggestions are put forward for the safe and reliable operation of similar equipment.
