Abstract

The invention discloses an insulation sleeve. The insulation sleeve comprises a terminal, an upper flange, an upper sealing plate, an insulating tube, a conducting rod, a lower flange, a lower sealingplate and a shielding electrode. The conducting rod is coaxially installed in the insulating tube and passes through the shielding electrode. One end of the conducting rod is fixedly connected to theupper sealing plate. The upper sealing plate is fixedly arranged on one end of the insulating tube through connection with the upper flange. The lower sealing plate is provided with the shielding electrode. The lower sealing plate is fixedly arranged at the other end of the insulating tube through connection with the lower flange. A protection cover is wrapped on at least one of a peripheral surface of the upper flange and a peripheral surface of the lower flange, wherein the peripheral surface of the upper flange is connected to the upper sealing plate, and the peripheral surface of the lower flange is connected to the lower sealing plate. The invention also discloses the protection cover used for insulating sleeve repairing and a repairing method of the insulating sleeve. Through wrapping the protection cover in advance, water vapor is kept out of the protection cover, a sealing environment in the insulation sleeve is ensured, an insulation sleeve electrode breakdown phenomenon is avoided, reliability of high pressure equipment operation is increased, and a service life of the insulation sleeve is prolonged.

Description

technical field [0001] The invention relates to the technical field of power transmission external insulation, and more particularly relates to a protective cover for repairing an insulating bushing, an insulating bushing and a repairing method thereof. Background technique [0002] At present, the insulating bushings widely used in high-voltage equipment such as GIS, H-GIS, DCB, PASS, and COMPASS in power systems mostly use gas-filled (SF6) bushing structures. For insulating bushings with higher voltage levels, its structure usually includes: terminal block, upper flange, upper sealing plate, insulating tube, conductive rod, lower flange, lower sealing plate and shielding electrode, and the conductive rod is coaxially installed on the insulating sleeve. Inside the tube, the upper end of the conductive rod is connected to the upper sealing plate, and the upper sealing plate is fixed on one end of the insulating tube through the bolt connection with the upper flange. The lowe...
