| 摘 要： | 变压器在空载合闸时会产生相当大的励磁涌流,这对变压器的稳定运行非常不利。文章主要分析了励磁涌流产生的机理,并介绍了一种利用控制三相开关合闸时间的方法来削弱励磁涌流。

| Abstract: | The excitation inrush current increase sharply when the transformer closing under the condition of no-load. The transformer working wiU be affected by it. The mechanism which cauls the excitation inrush current was analyzed in this paper, and a method that controUing the closing time of the three-phase switch to reduce the excitation inrush current was introduced. |
