摘要
通过对金庄煤矿矿井供电系统的探讨,得出结论:该矿地面变电所设两台S9-315电力变压器,主通风机以及该设备的控制回路和辅助设备各有两回路分别由风井变电所380 V低压配电柜供电,全矿井无功补偿集中于地面变电所10kV侧,通过无功补偿使电网的功率因数由0.696提高为0.902。井下供配电系统设有一座中央变电所,双回路供电,担负井下全部负荷用电。
The exploration of the power supply system in Jinzhuang mine shows that： there are two power transformers （$9-315） in the surface substation; main fan and its control loop and auxiliary equipments have two circuits respectively which are powered by 380V low voltage switch box in the air shaft substation; the reactive compensation of the mine focuses on the 10kv side of the surface substation and the reactive compensation leads to the increase of power factor from 0.696 to 0.902. The power supply and distribution in underground coal mine is equipped with a central substation with double-circuit power supply to undertake the power load of the overall mine.
