双频法测三相异步电动机温升实验

Experiment of Three-phase Asynchronous Motor Temperature Measure Using Double-frequency Method

介绍绕线异步电动机双频测温方法和原理,该方法设备简单,使用方便。通过三组实验数据对直接测量和双频测量进行温升比较。

This paper illustrates the method and theory of slip-ring rotor asynchronous motor temperature measure used double-frequency method.This method is simple and convenient to put in practice.The experiment data of three groups are shown to compare the double-frequency method with direct-measure method.
