用电流相量图判定三相变压器联接组别的方法

A Method to Distinguishing the Connection Number of Three-phase Transformer with the Current Phasor Diagram

介绍了三相变压器联接组的电流相量原理，并基于此原理提出了解决三相变压器联接组别问题的一种新方法——电流相量图法，说明了其判定原则和步骤，并通过一些实例对三相变压器联接组别的确定进行了分析。

The principle about the current phasor of three-phase transformer is introduced, and it puts forward a new method ＂＇Current Phasor Diagram＂, which is based on the principle in order to solve the problem of the connection number. By the explanation of the rules and steps, several examples to analyzing the connection number of the three-phase transformer are demonstrated.
