| 摘 要： | 针对某高压系统移圈调压器故障原因进行了探讨,从理论上研究了励磁涌流对调压器的破坏机理;研究了采取在调压器前端串入限流启动电阻的方法来减小励磁涌流对调压器破坏性作用的可行性。经过实测数据对比表明,加装限流电阻后,励磁涌流的幅值和持续时间下降都非常明显,操作过电压也得到抑制,具有较强的实用性。

| Abstract: | The causes of the failure of a high-voltage system transfer regulator are discussed. The failure mechanism of the magnetizing inrush current to the voltage regulator is theoretically studied. The authors studied the feasibility of using a current-limiting starting resistor in the front end of the regulator to reduce the destructive effect of the magnetizing inrush current on the regulator. The comparison of measured data shows that after the current limiting resistor is installed,the amplitude and duration of the magnetizing inrush current are very obvious,and the operating overvoltage is also suppressed,which has strong practicability. |
