Abstract

The invention discloses a composite insulator. The composite insulator comprises an insulation pipe and an umbrella skirt, wherein the umbrella skirt wraps the outer side of the insulation pipe, the insulation pipe comprises a first winding layer, a first semiconductor material layer and a second winding layer, the first winding layer deviates from the umbrella skirt, and the first semiconductor material layer is arranged between the first winding layer and the second winding layer and is arranged on a part of the cross section of an outer side of the first winding layer. The invention also discloses a manufacturing method of the composite insulator and a composite sleeve. By the mode, the semiconductor material layer is arranged in the insulation pipe, the interference of an electric field in the composite insulator can be reduced, the distribution of a local electric field is improved, the concentration of the electric field is reduced, the umbrella skirt is prevented from being electrically corroded by surface discharging, the shortening of the lifetime of the insulation pipe after long-term application is prevented, and the composite insulator can be applied to a strut insulator, the composite sleeve or other high-voltage power equipment.

Description

technical field [0001] The invention relates to the technical field of power transmission external insulation, and more specifically relates to a composite insulator, a manufacturing method thereof, and a composite bushing. Background technique [0002] At present, composite 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. The composite bushing includes a composite insulator and an internal center conductor. The composite insulator includes a fiberglass insulating tube and an outer silicone rubber shed. The center conductor is fixed on the upper and lower flanges at both ends of the fiberglass insulating tube. Terminals are arranged on the outer side of the upper flange. And has a high potential, one end of the lower flange is in contact with the shell of the high-voltage equipment, which is the shielding part close to the ground, the lower part of the composite bushing ...
