摘　　要：随着交流调速控制理论的日趋成熟完善,轧钢主轧线电机传动控制装置开始逐步使用矢量控制的交-直-交变频器.首先,介绍了交-直-交变频器的结构和工作机理及其矢量控制理论的原理,其次,论述了宣钢型材生产线主轧线使用西门子6SE70系列变频器的传动结构和日常维护过程中故障报警的处理及对重要参数的监测.表明宣钢型材主轧线采用异步电动机交-直-交变频矢量控制系统明显优于传统直流调速传动系统.With the AC velocity modulation control theory becoming more perfect, the motor drive control device of the main rolling line has gradually begun to use vector control AC-DC-AC converter. Firstly, its structure and working mechanism and vector control theoretical principles are introduced. Then the transmission structure of Simens 6sE70 series converter used in the main rolling line section product line of Xuanhua Iron and Steel Group is presented, togethor with handling of failure clarm and monitoring of key parameters during routine maintenace. The results suggest that the AC-DC-AC converter vector control system of asynchronous motor used in main section rolling lines of Xuanhua Iron and steel Group is significantly superior to the traditional DC velocity control system.
