摘要
在分析了变压器励磁涌流产生机理和现有变压器励磁涌流抑制技术的基础上,提出了一种新的方法来抑制变压器励磁涌流——在变压器的一次侧采用Zigzag接法。这种方法的基本原理是通过降低空载合闸过程中变压器铁心的饱和程度,从而达到减小变压器励磁涌流的目的。理论分析和Pspice仿真结果表明,这种方法能够减小变压器空载合闸时的励磁涌流。
A new approach, which adopted zigzag winding connection in primary side of transformer, is proposed in restraining inrush current for switching-in no-load transformer. The approach can decrease the saturation of the iron core, as well as the inrush current. After theoretic analyses and simulation by Pspice, this conclusion is obtained： The approach is effective to restrain inrush current for switching-in no-load transformer.
