<p><P>PROBLEM TO BE SOLVED: To provide a gas-insulated switchgear which is excellent in reliability by reducing the gas processing range in the case where a bus is broken up, and preventing the drop of insulation performance due to foreign matter generated at opening and closing of a earthing switch for inspection on bus side. <P>SOLUTION: A sealed container 15a for under connection, which has housed a connecting conductor 8 electrically connected to one end of a breaker 6, is arranged roughly vertically, and an sealed container 15b for upper connection is connected to the top of this sealed container 15a for under connection, and sealed containers 1 and 2 for buses arranged each roughly horizontally are connected to the upper parts of the sealed container 3 for a breaker, which are positioned on both sides of this sealed container 15b for upper connection, and the earthing switch 5 for inspection on bus side is arranged at the middle in the axial direction of the sealed container 15a for under connection positioned under a horizontal arrangement type gas-dividing insulating spacer 9. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
