摘要
针对电容式电压互感器油箱上部温度异常的问题,通过现场外观检查、电气试验和解体吊心检查发现电容式电压互感器防护铁磁谐振过电压装置损坏,详细分析了此类故障发生的原因并提出防护措施。
In view of Temperature abnormality of upper part of oil tank in capacitor voltage transformer, through appearance detecting, electric test, and suspended core examination, it is discovered that the ferromagnetic resonance over-voltage device has been destructed, the reasons of such fault is analyzed and specific measures of protection are improved.
