<p>PROBLEM TO BE SOLVED: To provide a gas-insulated switchgear in which the lengths of the branch bus-bars of bus-bar sectioning lines are reduced to reduce an installation area. SOLUTION: The left side bus-bar unit 1a and the right side bus-bar unit 1b of an (A) main bus-bar 1 and the left side bus-bar unit 2a and the right side bus bar unit 2b of a (B) main bus-bar unit 2 are horizontally arranged in parallel with an installation plane, so as to have the respective axial lines in parallel with each other and have the respective end parts overlap each other. In the overlapping parts, bus-bar sectioning lines 9 are connected in directions approximately perpendicular to the axial lines of the (A) and (B) main bus bars 1 and 2. Disconnectors 3 and ground switches 4 are integrally provided with the bus-bars and are provided on both the main bus-bar units 1a, 1b, 2a and 2b.</p> |
