球磨机同步电机励磁系统数字化改造

Digitization Reconstruction of Synchronous Motor Excitation System for Ball-mill Machine

针对选矿厂球磨机同步电机原励磁系统的缺点,运用西门子6RA70整流器、S7-300PLC及PROFIBUS-DP现场总线技术对励磁系统进行了数字化改造,构建了车间自动化网络,取得了良好的技术和经济效益。

Aiming at weakness of the former excitation system of ball-mill machine synchronous motor in mill run factory, succeeds in digitization reconstruction for the excitation system by applying ad- vanced Siemens 6RA70 rectifier, S7-300 PLC and PROFIBUS-DP fieldbus technique, constructs automation network of the workshop, and acquires better technique and economic benefit.
