摘要
交流异步电动机在恒流软起动过程中由于自身阻抗角的变化,导致SCR的触发区间、触发角、触发方式都有特殊的要求,详细分析了恒流软起动器可靠触发方法,在实践中证明这种方法是可行的,并且对于软起动的设计具有很强的指导意义。
During the soft starting period,because the impendence angle of the asynchronous motor changes,the trigger interval,trigger angle,trigger mode are specially demand.The method of reliable trigger is analyzed.This method is proved to be correct and useful in the practical application and is instructive for the design of the soft starter.
