三相变压器12种联接组的测定原理

Principle of Measuring 12 Kinds of Linking Group of Three-phase transformer

三相变压器联接组的测定通常采用交流法。这种方法是通过测量五个电压判断变压器的联接组。本文通过分析,得出了这五个电压数量关系的普遍公式,使得分析、判断简便易行。

Vsually we measure linking groups of threephase transformer in alternating current method.The method could be used to judge linking groups of transformer through measurement and analyses of five voltages.This paper concludes the five voltages equations can be used easily and conveniently,and they have universality.
