变频电源在三相异步电动机型式试验中的优劣势

Advantages and Disadvantages of the Application of Variable Frequency Power Supply into Type Test of the 3-phase Asynchronous Motor

主要介绍了变频电源用于电机型式试验时所具有的可随意调节试验电源的电压和频率、输出电压平衡度好、不易受电网的影响和能节省大量的电能等优势。但不容置否,变频电源也存在某些缺点。

Such advantages of the application of variable frequency power supply into type test of the 3-phase asynchronous motor as the adjustable voltage&frequency,well-balanced output voltage,not easy to be affected by the power grid and large quantity of electric energy saving,are mainly introduced,however,there are undoubtedly disadvantages of the variable frequency power supply either.
