摘要
本文针对节能绕组——三相“Y—△”串接“正弦”绕组的外部九根引出线之间的连接出错后所引起的后果及现象,从理论上进行了分析,并提出了如何判定接线错误的两个实用方法和一个改接的方法,在电机的节能改造中,具有一定的指导意义。
This paper has analysesed the phenomena and the consequences causedby the wrong connection among the nine leading-out wires from the outside of the three-phase “Y-△” series sine winding. Two practical methods to judge the errors produced inconnecting wires and one to correct these errors was proposed. These methods have a direc-tive significance to the energy-saving and to the reformation of a electric motor.
