摘要
为了解决高压大功率电机软启动技术实现难的问题,文中介绍一种基于单元级联型高压变频器的电机软起动应用方法,利用高压大功率变频器的特点,用其作为高压大功率电机的软启动器,使得高压大功率电机能够平稳、无冲击、大转矩启动。
In order to solves the problems which hard to achieve in the soft-start technology of high-vohage high-power motor, A soft-start application which is base on a unit cascade-type high-voltage inverter is introduced. Take advantage of the characteristics of the high-vohage high-power inverter is used as high-voltage high-power motor soft starter which making high- voltage high-power motor can have a smooth, non-impact, large torque start.
