摘要
详细介绍了四象限变频调速系统在下行皮带运输机中的应用。分析了三相交流异步电动机双机软驱动的变频传动系统运行特点、负载在主/从传动单元之间均匀分配的DROOP RATE控制方法、远距离电气控制方式、制动方式等。
The application of four-quadrant variable frequency speed regulating system in the dowward belt conveyor is introduced in detail. The operation characteristics of variable frequency drive system for three-phase AC asynchronous motor double soft drive, the DROOP RATE control method of load uniform distribution in the master/slave drive units, the remote electric control mode and braking modes are also analyzed.
