高压电缆隧道供配电和照明系统设计

摘要

With the improvement of urbanization level,the overhead lines with large area occupied are being replaced by the HV /EHV cables.Moreover,the low voltage power supply and distribution system is necessary for the ventilating system,lighting system,and drainage facility in the cable tunnels.Based on the engineering practice,the power supply and distribution system as well as the lighting system in high voltage cable tunnels were discussed in order to provide references for the relevant projects.%随着城市规划程度的提高，受规划制约，高压电缆正逐步取代占地较大的架空线。电缆隧道中的通风、照明、排水等设施都需要低压供配电系统。结合工程实际，介绍了高压电缆隧道的供配电和照明系统设计，旨在为相关高压电缆隧道供配电和照明系统设计提供参考。
