| 摘 要： | 为了分析在不同合闸方式下断路器合闸电阻阻值对变压器励磁涌流的影响,使用EMTP软件进行了仿真计算,计算结果表明,断路器合闸电阻对变压器励磁涌流峰值有明显的削弱作用,在确定是否取消断路器合闸电阻时,应考虑到它对励磁涌流的影响。

| Abstract: | Simulations by EMTP were done in order to analyze the effect of closing resistor on the inrush current of transformer in different closing types.Results show that closing resi stor inside circuit breaker can reduce the inrush current greatly,so the effect of closing resistor on limiting inrush current should be considered when the clo sing resistor is determined to be eliminated or not. |
