变压器励磁涌流产生原因及解决方法

Cause and Solution of Transformer Excitation Inrush Current

为了解决变压器空载合闸瞬间所产生的励磁涌流带来的问题,避免变压器保护装置误动作,可以采取控制合闸相位角、合闸回路串联阻尼电阻或加装涌流抑制器的方法进行处理,通过参考现场实际应用情况,这些方法都能很好地解决励磁涌流问题。

In order to solve the problem of excitation inrush current during no-load closing of transformer,and to avoid the false operation of the transformer protective device,it can control the closing phase angle,connect damping resistance in the closing circuit and install an inrush current suppressor.According to the practical application cases,the methods can solve the transformer excitation inrush current.
