节能减排是我国的一项基本国策,电气设计必须贯彻的重要技术政策。本文阐述了建筑工程电气设计的节能原则,节能途径,从电压选择,供配电系统、变压器选择、减少线路损耗、提高功率因数、电机起动和运行设备选择、照明节能等环节进行探讨。
Energy-saving emission reduction is a basic national policy of our country, the important technical policy that electrical design must carry out. This paper describes the energy-saving principles and energy-saving approaches for electrical design of buildings, and discusses the aspects of voltage selection, power supply and distribution system, transformer selection, reduction of line losses, improvement of power factor, selection of starting and running equipment, and lighting energy saving.
