The present invention reduces an area for installing a gas-insulated switchgear used as a power receiving equipment. This gas-insulated switchgear is constructed by installing multiple panels (1) side by side in line, each of said panels having the functions of an incoming panel (R), a transformer panel (F), and a VCT (V). The switchgear is provided with horizontal three-phase bus bars (12-15), which are used to connect the panels (1) together, for a maximum of four circuits. The space for installing the four circuits' worth of horizontal three-phase bus bars (12-15) is divided into two rows in the front-back direction and two stages in the vertical direction in the upper or the lower section of a case for the panels (1) in order to accommodate the maximum of four circuits, and the horizontal three-phase bus bars (12-15) for connecting the panels (1) together are arranged such that conductors of the respective phases are positioned horizontally in the front-back direction of the panels (1) at predetermined intervals. The horizontal three-phase bus bars (12-15) are provided with bushings (18-21) on both ends and arranged to run through the installation space, said bushings penetrating through a bus bar connection tank (8) from above or below the bus bar connection tank (8). |
