现场总线技术和通信技术的发展,改变了传统控制系统架构,有利于上层DCS系统对设备层的监控,方便了生产控制。如,智能MCC在一些熟料生产线上的应用,大大提升了水泥工艺自动化控制水平。1智能MCC及其系统架构MCC(Motor Control Center)是指对多台低压电动机回路实现集中控制和保护的低压开关柜。传统的MCC采用普通电气元件对电动机进行控制和保护,
The development of field bus technology and communication technology has changed the traditional control system architecture, is conducive to the upper DCS system monitoring of the device layer, to facilitate the production control. For example, the application of intelligent MCC in some clinker production lines has greatly enhanced the automation control level of cement technology. 1 Intelligent MCC and its system architecture MCC (Motor Control Center) refers to a plurality of low-voltage motor circuit to achieve centralized control and protection of low-voltage switchgear. The traditional MCC uses common electrical components to control and protect the motor,
