通过对煤矿井下提升绞车现行的三种电控系统的分析,指出交流电动机变频调速是一种最有发展前途的控制方式,而交一交变频控制系统更能适应煤矿井下的工作特点,是矿井提升绞车的理想控制系统,可在井下1.5～2 m提升绞车拖动系统中采用。
Through the analysis of the current three kinds of electric control system in the coal mine hoisting winch, it is pointed out that AC motor frequency conversion speed regulation is one of the most promising control methods, while the AC frequency conversion control system can better adapt to the coal mine work characteristics The ideal control system for mine hoist, which can be used in hoisting system of hoisting winch of 1.5 ~ 2 m downhole.
