变压器同名端与三相异步电动机首尾端判别方法分析

Analysis on the Discriminant Method of Same Side of Transformer and Head and Tail of Three-Phase Asynchronous Motor

阐述了用直流法判断单相变压器同名端、三相异步电动机定子绕组首尾端以及三相变压器同名端和首尾端的步骤方法,介绍了用同样的方法判别变压器和三相异步电动机却得到截然相反的结论这一问题,最终总结分析了变压器同名端与三相异步电动机定子绕组首尾端概念上的区别,对相关技术人员理解和分析这类问题具有指导性意义。

The method of judging the same side of single-phase transformer and three-phase transformer,stator winding head and tail of the three-phase asynchronous motor by DC method was introduced.It was expounded that identifying transformer and three-phase asynchronous motor by the same method obtains the opposite conclusion.The conceptual differences between the same name end of transformer and the first and last end of stator winding of three-phase asynchronous motor were summarized and analyzed.It is instructive for relevant technical personnel to understand and analyze such problems.
