Abstract
The study analyzes the phasor relationship between the connection group of three-phase transformer and the voltage of primary and secondary winding lines,and proposes analysis method.Based on the principle of magnetic conduction circuit and coupling inductance of the conducting part of transformer,the study introduces the same end of winding,determination of winding polarity,group clock representation and group connection.The study analyzes the phasor relationship between the connection groups,and the voltage of primary and secondary winding lines in 30 different connection modes of three-phase transformer sets;and summarizes the corresponding relationship,so as to provide guidance for practical application.
