摘要
煤矿井下防爆运输绞车担负着运输人员、材料和矸石的任务,是煤矿生产的重要设备。原有的控制系统具有能耗大、调速范围小、精度低、安全可靠性差等缺点,严重地制约了煤矿的安全生产,东海矿采用的交流变频绞车电控系统从根本上解决了原有防爆电阻调速控制系统所存在的各种弊端,是现有煤矿井下防爆绞车电控装置的最佳更新换代产品。
Frequency speed- regulating system which transports workers and coal gangue is very important for coal mine. The disadvantage of older system such as large energy consumption, small speed range and insecurity had a pernicious influence on coal mine production. The Donghai coal mine emplies frequency speed -regulating system, it resolves the disadvantages of older system, think it is the best replacement to coal mine.
