鼠笼型异步电动机的软起动技术

Soft Start Technique for Squirrel?cage Type Asynchronous Motor

普通结构的三相鼠笼型异步电机直接起动时起动电流很大,为避免对电网和负载设备造成冲击,采取了种种软起动方法,重点叙述了固态软起动法、变频器软起动法这两种新的起动方式及其应用。

There was large current in direct start of conventional three?鄄phrase squirrel?鄄cage type asynchronous motor. To avoid impact on network and devices loaded, soft start methods were used, and the two new start methods and applications of solid soft start method and soft start method of frequency converter were presented in detail.
