<p>PROBLEM TO BE SOLVED: To obtain a gas-insulated switchgear enables a suitable connection of isolated-phase bus to a three-phase package bus in an arbitrary order of phase, appropriately using a simple constitution. SOLUTION: A three-phase package bus 17 in which each phase bus conductor is arranged in parallel at an interval from each other, a connecting tank 8 which extends in the axial direction of the three-phase package bus 17, isolated- phase buses 18 which extend in the direction perpendicular to the axis of the bus 17, and are arranged in the extending direction of the connecting tank 8 with a certain space from each other, a plurality of conductor pieces 13a, 13b, and 13c, each of which is arranged extending in the direction perpendicular to the axis of the bus 17, is connected to one of individual bus conductors of the phase-isolated buses at one end portion, respectively, and is formed causing the other end portion to correspond to one of the axes of individual bus conductors of the bus 17, respectively, and a plurality of connecting conductors 9a, 9b, and 9c, each of which connects the other end portion of each conductor piece 13a, 13b, and 13c to one of the bus conductors of the bus 17, are provided. The connection between the three-phase package bus and the isolated-phase buses is performed in a prescribed order of phase.</p> |
