摘　　要：本文分析了其主变110kV侧发生铁磁谐振的可能性,仿真计算了铁磁谐振引起的过电压和过电流。提出了在电磁式电压互感器一次侧中性点与地之间串接金属氧化物避雷器的铁磁谐振抑制措施。The possibility of ferromagnetic resonance at 110 kV side of the main transformer is analyzed, and the overvoltage and overcurrent caused by ferroresonance are calculated. In this paper, the ferromagnetic resonance suppression measure of employing a metal oxide surge arrester between the neutral point of electromagnetic voltage transformer and ground is proposed.
