<p>PROBLEM TO BE SOLVED: To obviate operations of releasing and filling insulating gas by connecting the lower end of an internal conductor in a bushing and the interrupting portion of a gas-insulated switchgear main body using a connecting conductor. SOLUTION: A bushing 10 is installed at the upper part of the side of a gas-insulated switchgear(GIS) main body 4 with a mounting member 11 in between. An internal conductor is placed in the bushing 10 and a cable 13 is integrally connected with the internal conductor. A hollow tube 4a filled with insulating gas is placed in the GIS main body 4, a main circuit conductor 14 connected with the interrupter of an interrupting portion is housed in the hollow tube 4a, and a conductor 16 buried in a cable head 15 is connected with the main circuit conductor 14. A plurality of contactors 17 are placed in the conductor 16. A slip-on cable 19 is installed at the lower end of the cable 13 and a terminal 20 inserted in between the contactors 17 is installed at the end of the slip-on cable 19. The cable 13 can be connected and disconnected by inserting and withdrawing the terminal 20 into and from between the contactors 17.</p> |
