节约能源是当前调整国民经济中一项刻不容缓的重要任务。电能是能源的重要组成部分,就冶金工业而言,电能约占总能耗的四分之一,而冶金矿山由于产品产量吨位重,设备动力大,而地区分散,加之配变数量多,设备的负荷率及功率因素低等原因,电耗占总能耗的比重高达60—80％。 Saving energy is an urgent and important task in adjusting the national economy. Electricity is an important part of energy. In terms of metallurgical industry, electricity accounts for about one quarter of the total energy consumption. Due to the heavy tonnage of products and equipment, the power of metallurgical mines is large and the area is fragmented. In addition, The low load factor and low power factor, the proportion of total power consumption of up to 60-80%.
