民用建筑变电所供电主接线方式(续)

Power Supply Main Wiring Modes of Electric Substation in Civil Buildings( Continued)

民用建筑变电所供电主接线方式的设计,首先应确定用电负荷等级,以保证供电系统的合理性;其次,应考虑用电负荷容量、供电距离、当地电网现状及其发展规划等因素;再次,经技术经济比较后确定。结合五个工程项目主接线实例,介绍了前期策划、中期改进和后期实施等一系列设计过程。指出电气工程师应加强与供电公司沟通,为民用建筑提供安全可靠、技术先进、经济合理的供电系统。

The design about power supply main wiring modes of electric substation in civil buildings,should determine the electricity load levels in order to ensure the rationality of power supply system,and consider the load capacity,power distance,the local power grid status and development planning and other factors;and then be determined based on technical and economic comparisons.Combined with five engineering project main wiring examples,this paper introduced a series of design processes from the early stage plans,medium-term improvements and later-term implements.It was pointed out that the electrical engineer should strengthen the communication with power supply company to provide the safe and reliable,advanced and reasonable power supply system for civil buildings.
