摘要
分析了变压器直流偏磁的原因和变压器承受直流偏磁能力的影响因素,提出了一种根据变压器可承受的过电压倍数估算变压器可以承受直流能力的方法。
The reason of direct current bias of transformer and the factors to influence direct current bias withstand ability of transformer are analyzed. The method to evaluate direct current withstand ability of transformer is presented according to withstand overvoltage multiple of transformer.
