Abstract

The present invention relates to a no-partial-discharge type disc-shaped suspended composite insulator. The inner cavity of a metal steel cap is provided with a metal steel foot. A metal wire mesh are preset and laid at the inner cavity surface of the metal steel cap and the upper half part of the outer surface of the metal steel foot. Resin is cast and filled into the gap between the metal steel cap and the metal steel foot to be heated to be cured into a main insulation body with an umbrella disc, and the outer surface is coated with a silicone rubber umbrella skirt. Compared with the porcelain (or glass) composite insulator in the prior art, the embodiment of the present invention has the advantages that the production process is convenient, the mechanical performance and electrical insulation performance are more excellent, and the pollution flashover prevention performance is excellent. The most significant technical advantage of the invention is that the internal partial discharge phenomenon is eliminated and the product service life is prolonged.

Description

technical field [0001] The invention relates to an insulator for high-voltage power transmission, in particular to a non-partial discharge disc suspension composite insulator. Background technique [0002] The disk-shaped suspension porcelain (or glass) insulators widely used in the prior art, and the rod-shaped suspension composite insulators that have been vigorously promoted and applied in recent years have different advantages and have been widely used. However, the above two structures Due to the limitations of structural characteristics and properties of insulating materials, the products have their own shortcomings in performance. For example, disc-shaped suspension porcelain (or glass) insulators: due to their large capacitance, the voltage they bear during live operation is naturally and evenly distributed according to the capacitance, which is the main advantage of this type of product. However, due to the poor surface hydrophobicity of the ceramic (or glass) mate...
