市政隧道工程中供配电系统特点及电气设计探讨

Discussion on the Characteristics and Electrical Design of Power Supply and Distribution System in Municipal Tunnel Engineering

随着我国的城市的高速发展,高效而快速的通行需求越发重要。城市各类主干道中的隧道工程优势明显,方便人们出行的同时,带动了当地区域经济的发展。但便利的同时也时常伴随着各类安全隐患,因此对市政隧道工程设计内容中涉及的供电、消防以及交通安全设施等可靠性和稳定性关注度逐渐提高。我国的市政隧道工程仍处于高速发展中,供配电系统的安全与可靠运行是关键,因此在隧道工程设计时要充分考虑其负荷等级、负荷容量及相关设计内容,确保工程完工时的整体质量能够达到标准。本文从市政隧道工程供配电系统的自身特点并结合相关规范入手分析,探讨电气系统设计存在的问题和解决办法。

With the rapid development of China's cities and the concentration of traffic,efficient and fast traffic demand is more and more important.Tunnel engineering has obvious advantages in all kinds of main roads in cities,which facilitates people to travel and promotes the development of local regional economy.However,the convenience is often accompanied by all kinds of safety risks,so the attention to the reliability and stability of power supply,fire protection and traffic safety facilities involved in the design of municipal tunnel engineering is gradually increasing.The municipal tunnel engineering in China is still in rapid development,and the safe and reliable operation of the power supply and distribution system is the key.Therefore,in the design of tunnel engineering,it is necessary to fully consider its load grade,load capacity and related design content,to ensure that the overall quality of the completion of the project can reach the required standard.In this paper,the characteristics of the power supply and distribution system of municipal tunnel engineering and the relevant specifications are analyzed to discuss the problems existing in the design of the electrical system and the solutions.
