摘要
本文对干式浇注变压器励磁涌流进行分析,实现在空载合闸前,在变压器内建立漏磁场产生磁通,让变压器在空载合闸前产生励磁涌流。在系统中实现降低励磁涌流电流值以达到空载顺利合闸目的。
This paper analyzes the excitation inrush current of dry cast transformers,and realizes the establishment of a leakage magnetic field in the transformer to generate magnetic flux before the no-load closing,so that the transformer generates an inrush current before the no-load closing.In the system,the value of excitation inrush current is reduced to achieve the goal of smooth closing with no load.
