晶闸管调压软起动器的应用研究

Research on Application of Thyristor Soft Starter Controlled by Voltage

介绍了晶闸管软起动器的工作原理和起动方式,通过改变晶闸管控制角调节电动机两端的电压同时电路产生谐波,分析了谐波对电动机起动特性的影响和最佳起动方法,以及晶闸管软起动器的选择和应用场合。

This paper introduces the working principle and start methods of the thyristor soft starter. The terminal voltage of motor can be regulated by change of the control angle of thyristor, and the control circuit generate harmonics. In this paper, the influence of harmonic on the start characteristics of motor and the best start method are analyzed, as well as the choice and application field of thyristor soft starter.
