THREE-PHASE INTEGRATED GAS-INSULATED BUS-BAR

摘要

PROBLEM TO BE SOLVED: To provide a three-phase integrated gas-insulated bus-bar which enables drawing out branched bus-bars in two directions from one bus-bar container to make a gas-insulated switchgear compact.;SOLUTION: Three vertical drawing outlets 3, arranged in a longitudinal direction of a cylindrical bus-bar container 1, are formed in the bus-bar container 1 and three horizontal drawing outlets 4 are formed at axial positions approximately the same as those of the vertical drawing outlets 3 circumferentially. Three-phase main bus-bar conductors 7 are arranged so as to have one side of a triangle, having the three-phase main bus-bar conductors 7 at apices thereof, approximately in parallel with the horizontal drawing outlets 4. The leading ends of the main bus-bar conductors 7 are extended to the positions of the three vertical drawing outlets 3 successively from the main bus-bar of the phase closest to the vertical drawing outlet 3 and branched bus- bars 8 and 9 are drawn out through the vertical drawing outlets 3 and the horizontal drawing outlets 4 from the leading end positions of the main bus-bars.;COPYRIGHT: (C)2003,JPO
