隧道直流照明供配电设计要点分析

Analysis of Key Problems in Design of DC Lighting Power Supply and Distribution in Tunnel

结合浙江某城市交通隧道工程案例,对隧道直流照明供配电设计中的电压选择、线缆截面选择、供配电方案等重点问题进行分析,并指出现行隧道直流供配电设计存在的问题,提出优化方案。结果可为同类项目提供参考。

In this paper,based on a case of urban traffic tunnel project in Zhejiang Province,the key problems in the design of DC lighting power supply and distribution in tunnel,such as voltage selection,power quality and cable cross-section selection,load classification and power supply and distribution scheme,are analyzed.The problems existing in the current tunnel DC power supply and distribution scheme are pointed out and an optimization scheme is proposed.In order to discuss with the majority of colleagues.The results can provide reference for similar projects.
