晶闸管软启动控制器与变频器在中小型煤矿大功率电动机上的选择与应用

Selection and Application of Soft Starting Controller Via Thyristor and Variable Frequency Drive(VFD) in High Power Motors on Medium and Small Coal Mine

对晶闸管软启动控制器与变频器控制方式下的三相异步电动机的输出特性进行了较为详细的分析与对比,并对中小型煤矿大功率电动机软启动控制方式进行了选择,说明了软启动的必要性和可行性。

A specific analysis and comparison on the output characteristics of the three-phase asynchronous motor under the control mode of thyristor controller and VFD have been present,as well as the selection of the soft-start control mode on the high power motors on the medium and small coal mine. Also the necessity and accessibility of soft-start has been discussed.
