摘　　要：通过对新乡火电厂＃５炉＃１引风机电机的双速节电改造．将定子绕组接法由ＹＹ／△改造为Ａ．消除了原控制方式中的一系列隐患，使该电机可根据锅炉负荷情况进行双速运行．达到大量节电的目的．This Paper deale with the two- speed asynchronous motor transformation for the energy saving in draught fan No. I of furnace No. 5 of Xinxiang heat power station. It is discussed how YY/△ conneCtion of the Stator winding is changed into △/A conneCtion. Mean while,the data of energy saving have been collected in this Paper.
