三相变压器联结组别的口诀判定法浅探

Discussion on Three-phase Transformer Connection Groups Formula Determining Method

利用口诀的形式介绍三相变压器联结组别的组合形式和联结特点;揭示影响联结组别钟点数的三个因素及影响结果;并结合实例用口诀法对三相变压器联结组别的判定进行验证;同时提出联结组别的新的表示形式,从而用口诀法实现了联结组别判定的可逆性。

This paper presents groups combinations and coupling characteristics ot three-phase transIormer connec- tion by using pithy formulas; reveals the three factors influencing connection symbol clock points and the effect on outcome; and combines examples with the formula method to verify three-phase transformer connection groups judg- ment. At the same time, the paper also puts forward the new representation in connection set, thus the formula method realizes the decision reversibility in connection groups.
