摘　　要：详细介绍如何利用变频器的降速与制动功能来完成绕线型异步电动机断续工作制的温升试验的原理及方法。论述利用变频器的降速与制动功能代替频敏电阻器产生的节能效果,为绕线型异步电动机的"断续工作制温升"试验提供一种较为先进的试验方法。This paper introduces the principle and method of how to carry out temperature-rise test of wound-rotor induction motor at intermittent duty by reducing speed braking of inverter, and discusses energy-saving effect of inverter, which replaces the and frequency sensitive resistor, by reducing speed and braking. It is proved that this method is an advanced one for temperature-rise test of wound-rotor induction motor at intermittent duty.
