摘要
针对目前中小型煤矿提升机变频调速系统稳定性差、故障发生率高、能耗较多等诸多不足,提出了一种使用PLC与变频器相结合实现的新型煤矿提升机控制方案,对传统提升机调速系统进行改造,完成后系统运行稳定可靠、节能显著。
According to mine hoist control system has many disadvanges such as bad reliability, high fault rate ,large energy wasting and low efficiency. We adopt PLC and transducer to reform for original control system, so as to raise the safety, reliability, control precision and speed regulation performance of the whole electric controlled system.
