摘要
负载变压器会在双电源切换装置动作后产生严重的励磁涌流现象。本文分析了双电源切换装置切换流程及负载变压器磁通在电源切换各阶段的变化过程,得出切换过程中产生的磁通直流分量是引起励磁涌流现象发生的结论。
The load transformer will produce serious inrush current after the action of dual power transfer equipment(DPT).This paper analyzes the transfer process of DPT and the change process of load transformer flux in each stage of transfer process.It is concluded that the DC component of magnetic flux produced in the switching process is the cause of inrush current.
