摘　　要：在工程设计中,变压器容量选型是供配电设计的基础也是最为重要的环节。变压器的容量首先应满足负荷计算的要求。通常采用综合单位指标法和需要系数法相结合的方式。地下车库因为其用电的特殊性,消防负荷往往大于非消防负荷,采用需要系数法进行负荷计算时,要对比消防和非消防两种状态下的负荷总容量,并结合变压器的经济运行选择合理的变压器容量。In engineering design,transformer capacity selection is the basis and the most important link of power supply and distribution design.The capacity of transformer shall first meet the requirements of load calculation.Generally,the comprehensive unit index method and the demand coefficient method are combined.Because of the particularity of the underground garage,the fire load is often greater than the non fire load.When using the demand coefficient method to calculate the load,it is necessary to compare the total load capacity under the fire and non fire conditions,and select a reasonable transformer capacity in combination with the economic operation of the transformer.
