一起励磁涌流过大造成交流滤波器过负荷保护动作分析

Analysis of Overload Protection Action of AC filter Caused by Excessive Magnetizing Inrush Current

本文分析保护动作时刻故障录波,判断出选相合闸装置未能正确控制合闸的初相角是导致励磁涌流过大原因,并对保护装置在本次故障中的动作行为进行评价。

This paper analyzes the fault recording of the protection action time and judges that the primary phase angle of the phase selection switching device being not properly controlled is the cause of excessive magnetizing inrush current,Tt also evaluates the action of the protection device in this fault.
