摘　　要：串级调速系统广泛应用于绕线式异步电动机的启动和调速。然而在生产实践中因启动失控而烧毁功率开关器件的现象时有发生。本文在对事故原因进行深入分析研究的基础上,提出启动推β措施并设计了相应电路。实际证明,该措施有效地扼制了此类恶性事故的发生,提高了串级调速系统的可靠性。Tandem（speed） control system extensive is applied to winding line type induction motor start and adjustment. However in produce the inside destroy by firing the phenomenon of the power switch machine often has occurred because of start to lose control. This text put forward the measure of push β for the start in the foundation of thorough analysing and investigating the trouble reason and designed related the electric circuit. Practice proved the measure is availably, increases reliability of the tandem speed control the system.
