摘要
电力变压器空载合闸时会产生数值相当大的励磁涌流,这将会造成很多不利影响,容易造成变压器差动保护装置和敏感电力电子元器件的误动作,影响电力系统的安全稳定运行等。针对这一问题,本文介绍了几种抑制励磁涌流的方法。并加以比较分析。
The electric power transformer no-load closing will produce a large inrush current,which will cause many adverse effects,likely to cause the transformer differential protection devices and power-sensitive electronic components malfunction,affecting power system security and stability and so on.To solve this problem,this article will describe several methods of magnetizing inrush current suppression and comparative analysis.
