摘　　要：山区高速公路建设项目中隧道占比高,且隧道供电条件较困难,传统的10 kV供电方案难以满足项目远距离、大容量的供电需求。因此,对于多隧道供电的高速公路项目,有必要建设隧道群变电站向项目内所有隧道供电。主要针对隧道群变电站主接线方式、设备及导体选择等进行了研究。Due to the high proportion and the difficult power supply condition of tunnels in mountainous highway construction projects,the conventional 10 kV power supply scheme cannot meet the long-distance and large-capacity power supply demand.Therefore,for the multi-tunnel highway project,it is necessary to construct the tunnel group substation to supply power to all tunnels.This paper mainly studied the main wiring of the tunnel group substation and the selection of the equipment and conductor.
