软起动技术在泵站中的应用研究

Research on Application of Soft Startup Technique in Pumping Station

软起动装置不仅可根据负载的要求选择不同的起、停方式 ,从而调整起动转矩和起动时间 ,而且起动过程无电流冲击 ,停机过程可控制 ,因而其应用越来越受到重视。通过对传统电机起动装置和软起动装置起动、停机等性能的比较 ,认为 :软起动技术非常适合水泵机组的起停 ,它不仅在技术上已经成熟 。

Soft startup technique can not only select different mode of startup or stop to adjust the torque and time of startup according to the requirement of loading, but also avoid electric impulsion in the process of startup and be easily controlled in the process of stop. Thus, its application is more and more recognized. Through comparison with the startup and stop performances of traditional electric motor startup device, it is recognized that soft startup technique suits for startup and stop of pump unit, and it is technologically mature and economically reasonable.
