In a conventional gas insulated switchgear device, when transposing bus line phases, a separate unit which extends bus lines is provided and the bus line phase transposition was performed with the extension unit. However, because of the use of such extension unit, a bay interval in the gas insulated switchgear device is elongated and the installation area thereof is enlarged. In the present invention, a phase transposing unit for bus line conductors is provided in a bus line tank disposed within the conventional bay interval without providing the separate bus line extending unit. Thereby, a structure for transposing bus line phases without using the extension unit while keeping the installation area of the conventional gas insulated switchgear device unchanged.
A bus line container constituted by a plurality of tanks connected in a straight line shape in which three phase inclusive main bus line conductors are accommodated and which includes connecting ports through which connecting conductors to be connected with the bus line conductors are led out, characterized in that terminal portions near connecting portions for respective phases of the three phase bus line conductors in at least one of the tanks are extended so as to match an arrangement position of three phase bus line conductors in an adjacent tank.
A bus line container being constituted by connecting a plurality of tanks in a straight line shape each accommodates inclusively three phase main bus line conductors and the arrangement position of the respective phase bus line conductors is differentiated for every tank, characterized in that the bus line container comprising the three phase bus line conductors in the tank are arranged at apex positions of a triangle in such a manner that one side of the triangle extends perpendicularly to the horizontal direction;
