摘　　要：地铁车站低压用电负荷多,负荷类别复杂,在计算用电容量时要综合考虑负荷的同时系数和需要系数。根据车站变压器的运行方式,结合动照专业的低压负荷需求,对数据分析计算,合理确定用电负荷大小,选择合理容量的变压器。There are many low-voltage power loads in metro stations,and the load categories are complex.The simultaneous coefficient and demand factor of load should be considered comprehensively when calculating the power consumption capacity.According to the operation mode of station transformer,combined with the low-voltage load demand of dynamic lighting specialty,the data is analyzed and calculated to reasonably determine the power load and select the transformer with reasonable capacity.

关 键 词：动力照明 低压负荷 变压器容量 需要系数
