由于矿山生产和建设规模的不断发展,使用的感应电动机、变压器等用电设备逐年增多,无功功率增大,矿山功率因数降低,致使发电设备效率和输变电设施的供电能力降低,网路损耗增加,电压损失增大,因此,提高功率因数对生产企业和整个电力系统的经济运行和降低产品成本都是有意义的。老企业应根据实际情况,通过技术经济方案比较来选定提高功率因素的措施,而不能简单地采用增加大量电力电容器的方法。
Due to the continuous development of mine production and construction scale, the use of induction motors, transformers and other electrical equipment increased year by year, reactive power increased, mine power factor decreased, resulting in power generation equipment efficiency and power transmission facilities to reduce power supply capacity, the network Losses increase and voltage losses increase, so increasing power factor makes sense for both the economy of the manufacturing enterprise and the entire power system and the cost of the product. Old enterprises should be based on the actual situation, through technical and economic programs to compare the selection of measures to increase the power factor, rather than simply the method of increasing a large number of power capacitors.
