<p>PROBLEM TO BE SOLVED: To provide a gas insulation device which does not show deterioration of insulation performance even when the lightning impulse is applied later even if the insulation spacer surface is charged after application of opening/ closing impulse and application of a DC voltage. SOLUTION: The conductor connecting portions 40, 41 are provided at the position where a perpendicular lines (broken lines 44, 45 in the figure) on the center axis of conductors 30, 31, 32 from the end portions 42, 43 of the spacer side of the conductor connection portion do not become closer to the recessed surface of the insulation spacers 20, 21 than the end portions 52, 53 near to the flange surfaces 24, 25 in the projected surface side of the insulation spacers 20, 21 of the electrodes 50, 51 embedded to the flange portions 22, 23 of the insulation spacers 20, 21. Therefore, drop of deterioration of insulation dielectric strength when the lightning impulse is applied can be prevented without influence of the charges when the opening/closing impulse is applied to the insulation spacer.</p> |
