    Abstract:The design rationality of power supply and distribution system of the utility tunnel has direct impacts on the safety and stability of operation of the tility tunnel. At present,many design methods of power supply and distribution system of the utility tunnel are available,but there are no corresponding national standard drawings for reference. Through the comparison and analysis of commonly-used 10 kV power supply scheme and 0. 4 kV power distribution system of the utility tunnel,the design scheme of power supply and distribution system suitable for various types of utility tunnels is summarized,and the design of power supply and distribution system of the utility tunnel in the High-Speed Rail New Area,Xinyu,Jiangxi,can provide a reference for the design of similar projects.
    Key words:utility tunnels;power supply and distribution system;load level;0. 4 kV power supply scheme;10 kV power supply scheme;0. 4 kV power distribution scheme;fire compartment;reliability of power supply
 
    摘 要:综合管廊供配电系统设计是否合理直接影响综合管廊的安全稳定运行。目前综合管廊供配电系统设计做法较多,国标图集和一些地方的标准图集做法不尽相同。对常见的综合管廊10 kV供电方案和0. 4 kV配电系统进行分析对比,总结出适用于不同类型综合管廊供配电系统设计方案,并结合江西新余高铁新区综合管廊供配电系统设计,为类似工程设计提供参考。
