<p>PURPOSE:To provide a gas insulation switching device whose occupation space can be reduced by shortening a distance between a transformer and the gas insulation switching device when connecting the single-phase transformers with gas insulation buses. CONSTITUTION:Single-phase transformers A-C have first and second bushings, B1 and B2, B3 and B4, B5 and B6, respectively. The second bushing of the A-phase transformer and the first bushing of the B-phase transformer are connected with gas insulation buses G1 and G2, each having a gas insulation switch, and the second bushing of the B-phase transformer and the first bushing of the C-phase transformer are connected with gas insulation buses, G3 and G4, each having a gas insulation switch, and the second bushing of the C-phase transformer and the first bushing of the A-phase transformer are connected with gas insulation buses G5 and G6, each having a gas insulation switch. Each gas insulation bus is stack in double-layer vertically to the ground.</p> |
