对于特长的城市交通隧道工程,传统的低压供电方式难以满足用电设备的基本要求,而国家规范又明文规定隧道内严禁设置高压电线电缆。针对这一矛盾,从高压10 kV电源引入特长城市隧道工程的必要性、可行性和实施方案角度展开研究,表明将高压10 kV电源引入特长城市隧道工程是必要的、可行的和完备的技术方案,可有效指导工程设计。城市隧道一般指交通隧道,是连接公路、城市道路的重要节点,也包括水运隧道与管线隧道等。随着城市规模的扩大,特别是新老城区之间的交通往来形势严峻,综合考虑工程造价、施工周
For the characteristics of urban traffic tunnels, the traditional way of low-voltage power supply is difficult to meet the basic requirements of electrical equipment, and national regulations and expressly provides that the tunnel is strictly prohibited to set high-voltage wire and cable. In view of this contradiction, the necessity, feasibility and implementation of high-voltage 10 kV power supply are introduced in this paper. The results show that it is necessary to introduce high-voltage 10 kV power supply into the special urban tunnel project. The feasible and complete technical solutions , Can effectively guide the engineering design. Urban tunnel generally refers to the traffic tunnel, is an important node connecting roads, urban roads, including water tunnels and pipeline tunnels. With the expansion of the city scale, especially the transportation between the old and new urban areas, the situation is grim, taking into account the construction cost, construction week
