摘要
在电动机T型等效电路的基础上,充分考虑屏蔽套的影响因素,构建了屏蔽式三相异步电动机Π型精确等效电路,并提出了屏蔽套阻抗参数的计算方法,使得屏蔽套损耗可以在等效电路中计算出来。通过实例计算得到的结果与试验值对比,计算误差显著减小,具有很高的工程应用价值。
Based on T type equivalent circuit. In this paper, influence factor of the can is fully considered, type accurate equivalent circuit for canned three-phase induction motor is es- tablished, and calculation method for impedance parameter of the can is proposed, By doing this, loss of the can could be calculated in equivalent circuit. Through comparison of the practi- cal calculation result and test value, it is proved that the calculation error is significantly re- duced, and the method has higher engineering application value.
