This utility model provides a fully gravity-fed drainage structure for a switchyard, belonging to the field of water conservancy and hydropower technology. It includes a switchyard site, and a relay protection building and a GIS building respectively installed on top of the site. Both the relay protection building and the GIS building have basements for cable laying at their bases. The two basements are connected by a cable corridor. A site drainage ditch is installed around the outer perimeter of the switchyard site, and an indoor drainage ditch is installed around the inner perimeter of the basements. A corridor drainage ditch is installed inside the cable corridor, and a collection well is also installed in the basement of the GIS building. This utility model, through its gravity-fed and centralized drainage design, solves the problem of flooding caused by water pumps used for drainage when indoor water seepage occurs, especially in cases of pump equipment failure or power outage.
