Claims

[Scope of utility model registration request]

(1) In a structure in which a high voltage conductor is supported by an insulating spacer in a cylindrical airtight container containing an insulating gas, the high voltage conductor is installed along the inner circumferential surface of the airtight container and is axially attached to a part of the circumference. A cylindrical metal ring having a separated separation part, and a pressing means that is interposed in the separation part of this ring and engages with both ends of the separated ring to press and widen the gap between the separation parts in the circumferential direction. The earth potential side end of the insulating spacer to which the high voltage conductor is attached is fixed to the ring and is inserted into a predetermined position in the sealed container, and the pressing means presses the gap between the separated parts of the ring. and press the outer peripheral surface of the ring against the inner peripheral surface of the sealed container to lock and fix the ring to the sealed container and bring the ring and the sealed container into conductive contact. Characteristic conductor support structure for gas insulated electrical appliances.

(2) Utility model registration Claim 1 In the product described in claim 1, the pressing means includes an 8-part planar link whose opposite side in the circumferential direction is the end face of the ring separation part, and 2 parts forming the opposite side in the axial direction of this link. and an adjustment bolt that engages with the arms of the ring to change the distance between the arms, and by rotating the adjustment bolt, the gap size of the separated part of the ring can be changed. Conductor support structure.

(3) Utility Model Registration Scope of Claim 1 In the thing described in claim 1, the outer diameter of the ring is smaller than the inner diameter of the airtight container, and the spaced apart part of the ring is a wedge-shaped notch that opens in at least one axial direction. The pressing means includes a pressing piece having a trapezoidal part that engages with the wedge-shaped notch, and an adjusting bolt connecting the two pressing pieces, and the pressing means is configured to rotate the adjusting bolt. 1. A conductor support structure for a gas insulated electrical appliance, characterized in that the gap between the separating parts of the ring is expanded by reducing the gap between the pressing pieces facing each other.

(4) Utility Model Registration A conductor support structure for a gas insulated electrical appliance according to claim 1, characterized in that at least one insulating spacer is attached to the ring.
