变压器励磁涌流试验研究与分析

Test and Research of Transformer Inrush Current

本文中作者通过对单台变压器在相同初始合闸相角下进行重复多次空载合闸试验以及单台变压器在不同初始合闸相角下的重复多次空载合闸试验,研究了励磁涌流峰值的出现规律。

Through repeated no-loadinrush tests at the same initial closing phase angle and repeated no-load inrush tests at different initial closing phase angles, the occurrence law of peak excitation inrush current is studied, and the influencing factors of residual magnetism and initial closing phase angle on the magnitude of excitation inrush current are discussed.
