<p>PROBLEM TO BE SOLVED: To provide a gas-insulated switchgear which enables the reverse- engineering range of equipment to be made small when it is connected to a power cable without causing the overall dimension of the equipment to become large. SOLUTION: A breaker 2, a current transformer 4, a line isolator 5 and a lightning arrester 6 are contained inside a tank 1 filled with an insulating gas to constitute an incoming switching unit 7. Three leading parts 8 to 10 are provided at the same side of the tank 1 and a leading part 11 is provided at the side opposite to these leading parts. Bus isolators 12, 13 are respectively connected and arranged to the leading parts 8 and 9 neighboring to each other. A line grounding switch 14 is connected and arranged to the leading part 10, while a cable connecting part 15 is connected and arranged to the leading part 11.</p> |
