摘　　要：为了挖掘轻载电动机的节能潜力,根据电工原理,用图解的方法分3段分析了晶闸管三相调压器在改变控制角α时的调压工作过程,特别是α>90°以后,晶闸管在应导通区内导通不导电的现象.阐明了晶闸管三相调压工作时与单相调压具有不同的特点.指出晶闸管三相全程调压工作时,晶闸管需要宽范围跟踪触发.实验结果表明,晶闸管三相调压供电对降低轻载电动机的能耗有明显的效果.In order to explore the energy saving potential of the light load motor, on the basis of the principles of electrotechnology, the process of the three phase thyristors regulator adjusting voltage is analyzed in three segment with graphic methods when the control angle is changed, especially the phenomenon that the thyristor closing in onstate areas but nonconducting after big in 90 degrees. The differences of the three phase voltage and single phase voltage are discussed. When thyristor is working, the thyristor needs a wide range tracking touch when it is in three phase adjusting voltage. The experimental result shows that the thyristor three phase booster can save the energy of the light load motor obviously.
