摘　　要：超高层建筑配变电所设置应满足国家及地方相关规范要求，按用电性质分开设置配变电所有利于运行管理．其用电设备端子处电压降应满足规范要求．考虑设备运输方便，侧重考虑运营的安全性及经济性。通过计算某超高层建筑配变电所的有功功率损耗和电压损失。从能耗、高低压电缆造价、配变电所设备造价、设备运输等方面对超高层建筑配变电所选址进行技术分析及经济比较。建筑高度在100—150m的超高层建筑，可仅在地下层设置主配变电所，但应对低压配电线路的电压损失即电压降进行校验计算。The setting of distribution substation in super high-rise buildings should meet the requirements of national and local regulations. The distribution substation should be set up separately to facilitate the operation and management according to the nature of electricity consumption. The voltage drop at the terminal of the electrical equipment should meet the requirements of relevant regulations. Convenience in equipment transportation should be considered, and particular attention should be paid to the safety and economical efficiency of operation. By calculating the active power loss and voltage loss of the distribution substation of a certain super high-rise building, technical analysis and economic comparison are carried out from the aspects of energy consumption, cost of high and low voltage cables, cost of equipment in the distribution substation, and equipment transportation for the selection of location of distribution substation in the super high-rise building. For buildings with a height of 100- 150 m, the main distribution substation can be set up only in the underground floor, but the voltage drop in the low-voltage distribution lines, i. e. the voltage drop, should be calculated for verification.
