直流配电在城市步道照明设计中的应用研究

Research on the Application of DC Distribution in Design of Urban Footpath Lighting

近年来,随着高效直流电压转换器的出现,直流输配电问题得到解决,直流配电越来越受关注。以LED照明为代表的直流驱动照明技术的成熟,加速了直流配电在照明行业的推广,并得到越来越多的应用。以实际项目为例,比较交、直流照明系统方案及造价差异,对直流照明系统中,直流电源总控制柜内直流转换模块配置、各回路参数选择进行分析和总结。

In recent years,with the emergence of high efficiency DC voltage converter,DC transmission and distribution problems have been solved,and DC distribution has attracted more and more attention.Meanwhile,the maturity of DC drive lighting technology represented by LED lighting has accelerated the promotion of DC distribution in lighting industry,and has been more and more applied.Taking the actual project as an example,this paper compares the differences in lighting system scheme and project costs between AC and DC,analyses and summarizes the configuration of DC conversion module and parameter selection of each circuit loop about total control cabinet of DC power in DC lighting system.
