矿井提升机是矿山生产的关键设备,文章叙述了变频调速控制原理,对矿井提升机电控系统进行变频改造,使整个系统具有调速平滑、智能显示、检修方便等优点。同时也阐述了与传统提升机转子串电阻调速系统存在着控制方式复杂、调速性能差、效率低等问题。实践证明提升机电控系统采用变频改造后节能效果明显,具有很高的应用价值。
Mine hoist is the key equipment of mine production. The article describes the principle of frequency control of speed control, frequency conversion transformation of the mine hoist electronic control system, so that the entire system has the advantages of smooth speed, intelligent display, easy maintenance. At the same time, the problems of complex control mode, poor speed regulation performance and low efficiency are also described with the traditional hoist rotor-string resistance speed control system. Practice has proved that the elevator electromechanical control system with frequency conversion retrofit energy-saving effect is obvious, with high application value.
