摘要
低压直流配用电技术在民用建筑中的应用尚处于起步阶段,由于相关标准、产品和案例欠缺,不仅系统架构、电压等级等关键技术问题有待研究,行业内对其在建筑中应用的价值也有不同观点。为此,从民用建筑用电场景特点分析和建筑节能发展趋势入手,首先对直流配用电技术在民用建筑领域的应用价值进行分析;其次结合“十三五”国家重点研发计划的净零能耗建筑示范工程的建设和运行情况,分别从建筑直流配电和用电2个方面介绍低压直流技术在净零能耗建筑应用中的特点和关键技术,以期为低压直流配用电在民用建筑中的规模化工程应用提供参考。
The application of low-voltage DC power distribution technology in buildings is still in the preliminary stage.Due to the lack of relevant standards,products and cases,not only the system architecture,voltage level and other key technical issues need to be studied,its application value and merits are also under discussion.Therefore,starting with the analysis of the characteristics of building power consumption and the development trend of building energy conservation,this paper firstly analyzes the application value of DC power distribution technology in the civil buildings.Secondly,combining the construction and operation of the demonstration project of the national key research and development plan of the 13 th five-year plan,it respectively introduces the characteristics and key technologies of low-voltage DC technology in net zero energy consumption buildings from the perspectives of both power distribution and utilization,so as to provide references for the application of low-voltage DC power distribution and utilization in civil buildings.
