三相异步电动机△-Y改接节电的试验和分析

Power Saving Experiment and Analyses of Connecting in Three - Phase Asynchronous Electrical Motor

通过电机的型式试验,分析△-Y改接的节电情况。并根据我厂生产的JO23-7号三相异步电动机型式试验的统计数据计算出各种用控制电流的方法进行改接的转换电流数值范围及△-Y转换的临界负载率。

By practicing △-Y Connecting and analyzing power saving of electrical motor and our factory' s experiment data of JO2 3-7 three -phase asynchronous electrical motor, this paper gives its applying field and gains different ways of connecting changes and limit loading rate for referencing.
