| 摘 要： | 本文首先分析了变压器空载合闸时的瞬变过程、变压器励磁涌流形成的机理以及现有的变压器励磁涌流抑制技术，然后阐述了预充磁是通过改变变压器合闸时的初始状态来达到减小变压器励磁涌流的目的，最后利用仿真验证了在原方预充磁可以显著抑制励磁涌流。

| Abstract: | This paper firstly analyses the instantaneous change process during the transformer no-load switching and the reason of inrush current. It explains that pro-magnetization is to reduce the inrush current through changing the initial state of the transformer. Finally by using the simulation it prove that pro-magnetization at the original side can observably restrain the inrush current. |
