工业级车载交换机,-40~70℃宽温,M12连接头,5年质保今年春节假期期间的冠状病毒疫情波及整个中华大地,给全国人民的幸福生活、经济生产带来很大的不便。原定于年初四到鄂尔多斯某煤矿调试3台主井皮带高压变频器的工作也受到了影响,如果不能及时投产,将会影响部分北方地区供暖需求,给全国抗击疫情增加难度。结合对现场的实际情况的了解及新时达产品的易用性考量,采用备用方案----远程调试。
煤矿主井皮带系统情况介绍:
原系统配置:
皮带运输能力:1500吨/小时;
胶带:宽度1400mm,强度ST3150,钢丝绳芯;
带速:3.15米/秒;
运输长度:1110米;
倾角:+16°;
驱动功率:3*710kW,变频驱动;
主电机电压:6000V;
升级改造部分:驱动功率由原来的3*710kW(变频驱动),提高为3*1000kW(变频器驱动)。
本次升级改造方向:扩大产能,电机和变频器系统扩容,升级后的皮带运输能力预计可达到2000吨/小时。
现场控制方案确认:
原系统情况:该煤矿现场原系统同样采用高压变频器驱动,随着产能提高,原系统已经无法满足生产运输需要,原系统采用分别控制方案,三台变频器分别给定运行信号,通过手动调整运行频率来实现转矩平衡。
改造目标:新时达变频器采用主从控制droop功能alarm and printing of production process, processing of real-time collected data, control operation, analysis and statistics, etc. Through the high-resolution LCD and DLP splicing screen, the real-time working conditions of each process section and the trend picture of each process parameter of the whole plant can be displayed intuitively and dynamically, so that the operators can master the operation of the whole plant in time. At the same time, the central control room is also equipped with professional industrial database software. The number of variables required for historical data storage of the project is more than 8000. At the same time, the storage frequency of data is very high. Ordinary variables require 30 seconds to record one data. For variables with high data accuracy, such as "instantaneous flow", it is required to record once in 10 seconds. The stored data include water quality data, instantaneous flow and cumulative flow at each monitoring point, voltage, current, power and power consumption of lifting pump, gate, sludge pump, sludge scraper, mixer, blower and other equipment, start and stop
