Summary:Sutong GIL Integrated Pipe Gallery Project is a 1000 kV AC UHV transmission project, which is the world's first long-distance 1000kV GIL equipment cross-river power tunnel. The long distance of this project, the large amount of heat generated by the equipment, and the possibility of SF6 gas leakage inside the tunnel make the design difficult for the ventilation system. In this paper, the ventilation problem of Sutong GIL integrated pipe gallery is studied to determine the ventilation condition in this pipe gallery.
