Claims

[Scope of utility model registration request]

(1) In a gas insulated bushing that is inserted into an insulating tube filled with insulating gas and has a cylindrical potential control capacitor around a center conductor made up of a lower conductor, a cylindrical potential control capacitor is provided on the inner surface of the upper end of the potential control capacitor. A connecting fitting is arranged between the upper and lower conductors and connected to each other, and the radial dimension of the connecting fitting is approximately the same as the diameter of the center conductor so that they are flush with each other. Insulating bushing.

(2) Request for utility model registration in which a contact is fastened with bolts to the upper and lower surfaces of the connecting fitting on the inner surface of the upper end of a potential control capacitor, and this contact forms the center conductor and the lower conductor is connected to it. Gas insulated bushing according to item 1.

(3) The gas insulating bushing according to claim 1, wherein the gas is separated at the joint surface between the connecting fitting and the contact on the inner surface of the upper end of the potential control capacitor.
