协庄煤矿是一座产能为200万t/a以上的大中型现代化矿井,现有-50、-300、-550、-8504个开采水平。整个矿井用电设备繁多,供电系统复杂,电网的平均功率因数非常低。尽管在地面变电站对6 kV供电进行了集中无功补偿,取得了一些效果,但对处于矿井深处的用电设备却收效甚微,尤其是一些采掘大功率用电设备,由于位于电网末端,线路压降和电能损耗都较大,根本不能正常使用。使用BBW1系列矿用隔爆型无功功率自动补偿装
Xiezhuang Coal Mine is a large and medium-sized modern mine with a production capacity of over 2 million t / a. There are currently -50, -300, -550 and -8504 production levels. There are many power plants in the entire mine, the power supply system is complex, and the average power factor of the power grid is very low. Although the 6kV power supply in the ground substation has been centralized reactive power compensation, and achieved some results, but in the depths of the mine has little effect on the use of electrical equipment, in particular, some mining high-power electrical equipment, as located at the end of the grid, Line voltage drop and power loss are larger, simply can not be used normally. Use BBW1 series mine explosion-proof reactive power automatic compensation installed
