摘　　要：针对感应电机起动电流大的问题,提出应用可变电抗式软启动器降低起动电流.建立了软启动器的数学模型,通过分析晶闸管导通角与电机电流之间的关系,得出了晶闸管导通角与电机电流的数学解析表达式,为降低起动电流提供一定的技术支持.A method of using variable reactance type soft starter to decrea propsed to solve the problem of the induction motor＇s greater starting curr mathematical model is established, the relationship between the thyristor the motor current is analysed, and the mathematics analytic expression betw duction angle and the motor current is concluded, which provide some tec crease the starting current. se starting current is ent. The soft starter conduction angle and een the thyristor con- hnical support to de-crease the starting current.
