变压器绕组中的短路电流峰值的确定

Determination of Peak Value of Short-Circuit Current in Transformer Windings

阐述了变压器低压侧端口三相短路后，变压器绕组中短路电流的变化规律，论证了电源电压过零时短路，短路电流峰值有最大值的结论，并给出了一种确定短路电流最大值的数值计算方法。

The rules of short-circuit current variance under three-phase short-circuit condition at LV side of transformer are expounded in this paper. It is proved that short-circuit current has a maximum value while power voltage passes zero. A new numerical method of determining the maximum value of short-circuit is given.
