基于和利时PLC控制的矿用组合开关的研究

Research of Switch Combination used in Mining Based on Hollysys PLC Controller

采用和利时LM系列PLC作为主控单元的组合开关设计,不仅可以对系统进行短路、过载、断相、漏电闭锁、过压和欠压等保护,还可以对系统进行监测监控,使被控电动机的工作可靠性大大提高.采用超大、触摸式全中文彩色液晶显示屏,对组合开关的工作状态、参数和故障类型显示和记忆,友好的用户界面,具有良好的人机对话功能,提高了判断故障和排除故障的效率.

Adopting Hollysys LM series PLC as the main control unit can not only serve as protection against short circuit, overload, phase failure, undervohage and overvoltage, but also system monitoring and control. Motor under control can work more reliably. Large, touch-sensitive Chinese interface color LCD are used to display and memorize the switch combination. The user-friendly interface has good man-machine dialogue functionality and raises the efficiency of error probing and elimination.
