变压器T型等效电路中,一次侧和二次侧电势平衡方程式中的负号较多,在工程计算时非常不便.本文以单相双绕组变压器为基础,对变压器T型等效电路进行分析推导后得出结论:变压器电势平衡方程式中的负号来源于右手螺旋定则、楞次定律和基尔霍夫电压定律.为了除去不必要的负号,方便工程应用,指定另一种变压器一次侧和二次侧的电动势正方向,简化了变压器T型等效电路图.

As far as T-type equivalent circuit of the transformer is concerned, there are more negative signs in the potentials balance equation both in the primary side and the secondary side. It is very inconvenient in en- gineering calculations. In this paper, based on single-phase two-winding transformer, we analyse the transformer T-type equivalent circuit. The result shows that: negative signs in transformer balanced equation for the potential comes from the right-hand screw rule, Lenz's law and Kirchhoff's voltage law. In order to remove the unnecessa- ry negative signs and easily to be used in engineering, another positive direction for electromotive force both in primary side and the secondary side is put forword. In the end, the transformer T type equivalent circuit ...
