摘要
阐述了电力机车功率因数补偿装置的故障问题，探讨了补偿电路工作时的极限状态，指出晶闸管误导通可能出现最危险的过电压，对此进行了理论分析计算，并建议改变操作控制方式来消除此类故障．
The author described the breakdown of PFC on electric locomotive, discussed the limiting conditions for compensation circuit. It is indicated that mis-trigger of thyristor may lead to the most dangerous overvoltage. Theoretical analysis & calculations have been conducted and suggestions made to eliminate such breakdown with different control mode.
