摘　　要：在高速公路隧道照明供电中,直流供电系统因其成本更低、可靠性更高、节能环保及施工快捷等优势,逐渐取代了交流供电系统。该系统在安徽、浙江、江苏、江西、山东等省的高速公路隧道照明实际应用中,取得了良好的效果。以安徽省池(州)—祁(门)高速公路重阳2号特长隧道照明供电为例,介绍了直流供电的意义和实施方案,并通过数据对比了直流供电与交流供电在节约能源方面的优势。希望能够为今后高速公路供电选择提供参考。In the lighting power supply of highway tunnels,DC power supply system has gradually replaced the AC power supply system due to its advantages such as lower cost,higher reliability,energy saving,environmental protection,and fast construction.This system has achieved good results in the practical application of highway tunnel lighting in Anhui,Zhejiang,Jiangsu,Jiangxi,Shandong and other provinces.This article takes the lighting power supply of the Chongyang No.2 extra-long tunnel on the Chi(zhou)-Qi(men)Expressway in Anhui Province as an example,introduces the significance and implementation plan of DC power supply,and compares the energy saving effects of DC power supply and AC power supply through data.It is hoped that this article can provide a reference for future highway power supply selection.
