  • Patent number: 6509522
    Abstract: In a three-phase integrated gas insulated bus, three vertical outlets 3 are formed in the longitudinal direction of a cylindrical bus enclosure 1 and three horizontal outlets are formed in almost the same axial position as these vertical outlets 3 in the circumferential direction. The three-phase main bus conductors 7 are laid out to ensure that one side of a triangle having the apexes where three-phase main bus conductors 7 are located is approximately parallel to these horizontal outlets 4. The main bus conductors 7 are extended to the three vertical outlets 3 sequentially starting from the main bus of the phase closest to the vertical outlets 3, and branch buses 8 and 9 are led from the tip positions thereof to the vertical outlets 5 and horizontal outlets 6.
