<p>PURPOSE:To provide a GIS comprising power supply side buses and load side buses arranged vertically in parallel on the same side of a VCT in which the connection bus in each connection duct is arranged rationally. CONSTITUTION:In a GIS where power supply side buses 21 and load side buses 22 are arranged vertically in parallel on the same side of a VCT 1, a bus connection duct 28 is disposed between the VCT and both buses. A VCT connection duct 29 connecting the bus connection duct and the VCT is disposed above the VCT and a bus being connected reciprocally with the current transformer of the VCT is constituted of a coaxial bus 31, 34, 39 in each connection duct. Since a coaxial bus is employed, arrangement of the connection bus can be rationalized and the required space can be reduced.</p> |
