变压器空载合闸励磁浪涌电流分析

Analysis of Excitation Surge Current of Transformer No-load Closing

本文分析了变压器励磁浪涌电流形成的原因,以及变压器空载合闸浪涌电流的特点;同时进行试验以验证分析的正确性;最后基于以上分析过程以及影响空载合闸涌流大小的因素,提出减小变压器空载合闸浪涌电流大小的措施。

the cause of the transformer excitation surge current and the characteristics of the transformer no-load switching surge current are analyzed. At the same time,the test is carried out to verify the correctness of the analysis. Finally,based on the above analysis process and the factors affecting the value of the no load switching inrush current,the measures to reduce the surge current of transformer no-load closing are proposed.
