ABB中压传动系统在钢管轧制中的应用

Application of ABB Medium Voltage Drive System in Steel Pipe Rolling Line

在天津钢管公司168新型钢管厂钢管轧制中,穿孔机主传动同步电机驱动应用了ABB公司先进的ACS6000中压变频调速传动系统。该系统是以IGCT为功率元件的一种中性点钳位整流变换器。详细介绍了该厂ACS6000中压变频传动系统的组成结构、送电、停机操作和在轧钢系统的应用以及常见的故障处理方法,提供了运行曲线。经过实践,证明了该系统具有响应速度快,控制精度高,运行稳定,可靠性好等特点,并提高了生产效率。

In the steel pipe rolling of 168 New Pipe Mill Plant of Tianjin Pipe （Group） Corporation （TPCO）, ABB advanced ACS6000 medium voltage variable speed drive system is used for driving piercing mill main drive synchronous motor. This system is a neutral-point-clamped （NPC） converter equipped with so called integrated gate commutated thyristors （IGCT）. Detailed described the configuration of the system, power on and off operation, the application in rolling mills, some common faults handling methods and running curves. The practical application shows that the designed system has fast and accurate torque and speed response,runs well and reliable. And that will be helpful for improving the productivity in the seamless pipe rolling line.
