摘要
针对目前轧钢工艺场合较多地采用交流同步电动机传动的情况,论述了利用6SE70系列逆变器、6RA70直流调速器及可编程控制器研发同步机交-直-交传动系统,并成功应用于安阳、北台、宁波1 780 mm热连轧卷取机上,此方案的研发及成功实施,为中型容量交流同步电机提供了一个性价比很高的解决方案。
Aim at the situation of AC-synchronous speed adjustable system in many main drive of steel rolling technological,the electric control system of voltage source AC- DC- AC based on 6SE70 inverters,6RA70 serial DC speed regulating device and PLC was introduced. And the electric control system has been successfully applied to synchronous coiler of 1 780 mm Hot Strip Mill in Anyang, Ningbo and Beitai Iron ＆ Steel Group Co. Ltd. The control system steady and reliable which provides a very cost-effective solutions for middle sized AC-synchronous motors frequency controlled speed regulating system based.
