市政隧道工程中供配电系统特点及电气设计

Characteristics and Electrical Design of Power Supply and Distribution System in Municipal Tunnel Works

供配电系统作为市政隧道工程建设体系的重点内容,通过合理规划设计可以保障隧道用电安全性与可靠性,保障市政隧道始终安全通畅。随着我国市政隧道工程建设规模的持续扩增,政府部门对于该类工程项目施工规划以及建设问题予以了高度重视。为更好保障车辆在隧道中安全通行,以经济可靠、节能环保为原则,对新时期市政隧道工程中供配电系统及电气设计特点进行分析,并提出了设计重点及优化措施。

As the key content of the municipal tunnel construction system,the power supply and distribution system can ensure the safety and reliability of tunnel power supply through reasonable planning and design,and ensure that the mu-nicipal tunnel is always safe and smooth.With the continuous expansion of the construction scale of municipal tunnel pro-jects in China,the government departments have attached great importance to the construction planning and construction of such projects.In order to better ensure the safe passage of vehicles in the tunnel,based on the principles of economy,reliability,energy conservation and environmental protection,this paper analyzes the characteristics of power supply and distribution system and electrical design in the municipal tunnel project in the new era,and puts forward the design focus and optimiza tion measures.
