<p>A gas-insulated substation comprises at least two transformers (11a, 11b) arranged side by side on a first floor (FL1), gas insulated switching apparatus including disconnecting switches (12a, 12b) disposed on a second floor (FL2) at a level different from that of the first floor, and branch bus-bars (17a, 17b) extending vertically and parallelly from lead boxes (11c, 11 d) which project from facing sides of the respective transformers, the branch bus, bars being connected to the disconnecting switches. The substation further comprises main bus-bars (19) each interconnecting the tranformers through the branch bus-bars and the disconnecting switches, so that the length of a main bus-bar is made to be substantially equal to the distance between the lead boxes projecting from the facing sides of the respective transformers.</p> |
