矿山企业(煤矿、金属矿、非金属矿)是耗电量很大的单位,如抚顺某矿日耗电量平均在57万度,而耗电量占半数以上的是四大系统,即通风、排水、提升、运输。由于这四大系统的拖动电机都采用了旧式拖动方法,所以耗电量大,无功损耗也严重。尤其是通风、排水、提升系统,在设计时还要考虑服务年限(即井下进尺深度),所以选择设备容量偏大,在若干年后才能全负荷运行,
Mining enterprises (coal mines, metal mines, and non-metallic mines) are units that consume large amounts of electricity. For example, a mine in Fushun consumes an average of 570,000 kilowatt-hours of electricity per day, while the power consumption accounts for more than half of the four major systems. , drainage, lifting, transportation. Because the drag motors of these four systems have adopted the old drag method, the power consumption is large, and the reactive power loss is also serious. Especially for ventilation, drainage, and lifting systems, the service life (that is, the depth of downhole footage) must also be considered in the design process. Therefore, the capacity of the equipment is selected to be large, and the full-load operation can be performed only after several years.
