摘要
根据矿井供配电系统现状,以及改造后的矿井电力负荷校验现有电源线路(按功率因素为0.9考虑),对凉山州益门煤矿机械化改造后的供配电系统进行了方案设计和设备选型。经验算,改造后矿井电源线路除经济电流密度不满足要求外,其余如温升(载流量)、电压损失均满足要求;本次为机械化改造供配电设计满足相关规程、规范的要求。
According to the present situation of the mine power supply and distribution system and the reformed mine power load to check the existing power line (considering the power factor of 0.9),the scheme design and equipment selection of the power supply and distribution system after mechanization transformation in Liangshanzhou Yimen Coal Mine are carried out.Empirical calculation shows that after the transformation,except for the economic current density,the rest of the mine power supply line,such as temperature rise (carrying capacity) and voltage loss,all meet the requirements.This time,the design of power supply and distribution for mechanization transformation meets the requirements of relevant regulations and specifications.
