The utility model discloses a 110kV HGIS double-bus double-column type power distribution device, which effectively saves land occupation and saves an arrangement scheme of framework steel. A combinedbus framework 5 is of a door-shaped structure formed by two stand columns and a cross beam, two sets of tubular buses 2 are hung below the cross beam and connected with SF6 inflation sleeves 4 of incoming line HGIS equipment 7 respectively, and an incoming line 1 is connected into the SF6 inflation sleeves 4 of the incoming line HGIS equipment 7; wherein the outgoing line HGIS equipment 8 and theincoming line HGIS equipment 7 are arranged side by side in a single-row manner, and the two groups of tubular buses 2 and the outgoing line 9 are respectively connected with the SF6 inflatable sleeve 4 of the outgoing line HGIS equipment 8. The bus framework has the beneficial effects that the framework column between the two groups of suspension tube buses is canceled, so that the width of thebus framework is reduced, the framework steel quantity is effectively saved, and the occupied area is saved; after a framework column is canceled, the height of the direct lightning protection protected object is obviously reduced to 9.0 m; and the anti-seismic level of electrical facilities is improved, and the application range is wider.
