摘　　要：研究了电压合闸相角对笼型三相异步电动机全压直接起动电流最大峰值的影响规律。通过解析计算从理论上分析了合闸相角与起动电流最大峰值的关系,并以一台110 k W三相异步电动机为例,通过有限元仿真及试验验证了理论分析的正确性。The influence of switching angle on the maximum starting current of squirrel-cage three phase induction motor was studied. Through theoretical analysis, the relation between switching angle and maximum starting current was concluded. And the conclusion above was validated via finite element simulation and test on a 110 kW motor.
