摘　　要：民用建筑供电变压器选址遵循深入负荷中心原则,且供电半径在规范、技术措施中有相应要求。通过线路电压损失计算分析10/0.4kV变压器的供电半径,并对某工程项目中变压器不同配置方式进行经济分析,为建筑电气节能设计提供理论支持。The site selection of power supply transformers for civil buildings is conducted by following the principle of going deep into load center and there are requirements for the power supply radius in codes and technical measures. The power supply radius of a 10/0. 4 kV transformer is analyzed based on the line voltage loss calculation, and an economic analysis of transformers in different configuration ways in a project is conducted, so as to provide theoretical support for the electrical energy-saving design for buildings.
