At this time, since the gas in the lower gas section m22 remains sealed, the operation of the main bus 14 can be continued, and there is no need to stop only the operation of the raw bus 1s13. Take out the insulating spacer B with the center conductor and Vc9 from the obtained work manhole and replace it with a new insulating spacer 2. After the replacement work is completed, remove the bushings 2 and 4 from the circuit breaker 1, and remove the removed bushing 2. 4 is airtightly connected to the opening 7 lange S and the opening Aranshiro via the contact plate 7, the pulp proverb is closed, and the valve 31 is closed.
Gas is filled into the intermediate gas compartment 21 from 33 and into the upper gas compartment 1120 from pulp (not shown).

! It is airtightly connected to the partition plate so that it can be installed and removed from the 1121 side, while the lower gas section = 229411
A similar effect can be obtained by airtightly connecting an insulating cover 41 that can be attached and removed from the partition plate, connecting the center conductors 27 and 28 of the two with a tulip contact 26, and forming the gas compartment 4. It will be done. In the end, the screw Wc device may be configured using two gas compartment insulating members that can be attached and removed from the gas compartments 21 and 22 sides, respectively.
