摘要
在有色金属矿山实际生产中,供电系统短路容量,以及电力变压器额定容量,对于矿山用电设备的启动方式的确定,是十分重要的计算依据;同时在选择用电设备启动方式时,还需根据其供电线路距离,结合供电线缆截面进行校验,控制电压偏差,以便确定合理的启动方式,为矿山用电设备的安全运行提供基础保障。
In the actual production of non-ferrous metal mines, the short circuit capacity of power supply system and the rated capacity of power transformer are very important for the determination of starting mode of mine electrical equipment. At the same time, when choosing the starting mode of electric equipment, it is necessary to check the voltage deviation according to the distance of the power supply line and the cross section of the power supply cable, so as to determine the reasonable starting mode and provide the basic guarantee for the safe operation of mine electric equipment.
