三相变压器12种连接组规律探析

An Inquiry into Laws on 12 Kinds Linking Group of Three-phase Transformer

三相变压器连接组问题分为两类 :第一类是已知三相变压器的连接方法 ,判定其组号 ;第二类是给定了组号 ,确定三相变压器的连接 .通过分析得出了三相变压器 1 2种连接组的连接规律 。

s:There are two types of problems on three-phase transformer linking groups:one is to mark the grorp's numbers when the linking manner of the transformer is known,and the other is to determine the linking manner when the group's numbers are given.This paper intends to draw conclusions by analyze 12 kinds linking groups of the three-phase transformer.These laws can be used for the solution of the tow types of problems.
