三相变压器的联接组判定方法

A Way to Determine the Connection Group of Three-phase Transformer

三相变压器绕组的联接组确定方法一般有"时钟法"和"线电压正三角形重心重合法",两种方法各有利弊。为了能快速且正确地解决判定三相变压器的联接组以及利用三相变压器的联接组号来画三相变压器的联接组图等问题,本文提出了一种有效解决三相变压器的联接组判定的方法,即"旋转线正电压三角形法"。

The general methods to determine the three-phase transformer connected group were ＂Clock law＂ and ＂Coincidence voltages are triangle of gravity＂, but they both have disadvantages. In order to quickly and accurately to solve the problems about the connection group of three-phase transformer, this paper puts forward an effective solution for three-phase transformer connection group determination methods.
