部の構造に改良を施したガス絶縁開閉装置に係る。[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a gas-insulated switchgear, and in particular, to a connection section of each device of a gas-insulated switchgear that is assembled on-site. This relates to a gas insulated switchgear with an improved structure.

At the fi1M site, due to land availability and salt damage countermeasures, the electrical equipment that makes up the substation and the l7t111'1 site is sealed with an insulating medium that has excellent insulation and arc-extinguishing properties, such as SF6 gas. Gas insulated switchgear is used. The gas-insulated switchgear for this scale is constructed by arranging the disconnectors, disconnectors, and other necessary equipment three-dimensionally, narrowing the distance between each piece of equipment, and significantly reducing the site area. There is.
ところで、この様なガス絶縁開閉装置のうち、第２図に
示した様に、上部に２つの口出し部１ａ。By the way, in such a gas insulated switchgear, as shown in FIG. 2, there are two openings 1a at the top.

に輸送して、現地にてそれらを組立てていた。A current transformer 2 and a disconnector 3 are installed above a gas breaker 1 having a voltage class of 275KV to 50KV.
In J3, which is as high as 0KV, the height of each piece of equipment was so high that it was impossible to assemble and integrate them and then transport them to the site. Therefore, the gas breaker 1 and current transformer 2 can be connected in advance and integrated into a unit, and then the disconnector 3 can be connected after transporting the unit to the site, or each device can be transported separately and transported to the site. I was assembling them.

われていた。However, when assembling each component on-site, as shown in Figure 3, foreign matter 4 generated during the connection work may enter the gas-insulated switchgear. If it falls and adheres to an insulating material such as the insulating spacer 5 disposed at the connection part, there is a risk of voltage resistance failure at a later date, and the reliability of the gas insulated switchgear is significantly impaired.
