摘要
通过对千秋煤矿矸石山绞车的变频调速电控系统的改造,改善了矸石山绞车的运行状况,提高了矸石山绞车的排矸能力,降低了提升电耗,创造了十分可观的经济效益。
By the fact that the frequency conversion speed regulation electricity to thousand years coal mine hillock winch charges systematic reforming,the operational state having improved the hillock winch, has improved the hillock winch row cash ability , having reduced the lifting electricity has consumed , created the very considerable economic effect.
