<p>PURPOSE: To provide an excellent gas-insulated switchgear whose arrangement constitution is simple and whose installation space can be reduced effectively. CONSTITUTION: Respective horizontal lead parts 1a at the upper part and the lower part of respective circuit breakers 101 to 104 are connected, via connecting buses 12, 13 extended to a direction perpendicular to the axial direction of the respective horizontal lead parts, to horizontal lead parts, at a higher order, which are installed at circuit breakers to be connected in the neighborhood. Grounding devices 2 for operations and disconnectors 3 for buses are connected, on the same axis as the respective horizontal lead parts, to the respective horizontal lead parts 1a at the upper part and the lower part. Ring-shaped buses are constituted of the respective circuit breakers 101 to 104, of the connecting buses 12, 13, of the grounding devices 2 for operations and of the disconnectors 3 for buses. Apparatuses 14, 16, for line connection,which constitute circuit units U1 to U4 are connected, on the same axis as the horizontal lead parts for the respective circuit breakers and on sides opposite to the respective circuit breakers by sandwiching the connecting buses, to the connecting buses.</p> |
