摘　　要：为了对被试高压电机在不能采用直接负载法或降压负载法时进行温升试验,介绍了叠频试验法;通过采用变频机组提供试验电源,实现电源电压与频率的调节。试验数据的自动采集采用WT3000数字功率计与计算机通信,实现数据处理、存储和监控一体化。When the temperature-rise test on high-voltage motor cannot be carried out by means of the direct load method or the dropping-voltage load method, this article suggests the superposing-frequency method. The frequency changer set is adopted to providing test power, which regulates the electric voltage and frequency. The experiment data was collected automatically based on WT3000 digital power meter communicated with computer. It makes data processing, storing and monitoring as a whole come to true.
