| 摘 要： | 以相同容量厂用三相△／△／△联接的幅向分裂变压器和轴向分裂变压器为例，分析分裂变压器短路事故损坏的原因。在计算变压器短路电流时，考虑到轴向分裂变压器初级两个并联绕组的排列结构。计算了其安匝分配。最后对两种分裂变压器短路电磁力进行了计算，分析轴向分裂变压器损坏较多的原因。

| Abstract: | Take an example of the three-phrase △/△/△ connection axial split and radial split transformers which are in same capacity and used for station service,the reason causing short circuit accident is studied. Considering the structure of two high voltage parallel windings of axial split transfoner, the distribution of ampere-turns in the windings is calulated. At last,the short circuit magnetic force of two kinds of transformer are computed, analyzed and compared. |
