<p>PURPOSE:To reduce a space for setting gas-insulated buses, to facilitate an operation for assembling the gas-insulated buses, and to improve the earthquake resistance of these buses, by arranging high-tension gas-insulated buses and medium-tension gas-insulated buses for three phases in the shape of a triangle respectively in a three-phase transformer constructed by combining single-phase transformers divided into a plurality. CONSTITUTION:A single-phase transformer 1A is arranged in the number for three phases 1A-1C, thus constituting a three-phase bank 1. Moreover, single- phase transformers 2A-2C are arranged in the same way in opposition to the above, thus constituting a three-phase bank 2. Between these three-phase banks 1 and 2, high-tension gas-insulated buses 16A-16C, 26A-26C, and medium-tension gas-insulated buses 20A-20C, 30A-30C, which are employed for connection to high-tension element and medium-tension element to gas- insulated on-off devices, are disposed. In this construction, the high-tension gas-insulated buses 16A-16C, 26A-26C, and the medium-tension gas-insulated buses 20A-20C, 30A-30C, are arranged in the shape of a triangle respectively, while each bus arranged in the triangle is coupled to others therein by a coupling metal fitting 8 or 9 so as to be fixed.</p> |
