Abstract

The invention relates to a hollow composite insulator used in 1100kV composite apparatus in power industry, and a producing method of the insulator. The insulator comprises an end connecting part, an insulation tube and an umbrella. The end connecting parts are stuck on the two ends of the winding tube. The invention is characterized in that: an integrated umbrella is stuck at the out side of an insulation tube; the insulation tube is a wound tube with an inner liner; the umbrella is an injecting-formed part made of high-temperature vulcanization silicon rubber, and because the inner liner of the insulation tube is an epoxy resin adhesive and SF6 decomposition mixing and solidifying structure, the anti-corrosion performance of the product is greatly increased; the umbrella is hot-solidified on the surface of the insulation tube at high vacuum and high temperature, so the connecting strength between the umbrella and the insulation tube is high, and the product performance is more stable and reliable. When winding the insulation tube, a track is first simulated on a computer, and then pins are fixed on both shaft ends of the mold core. When winding, a mechanism with even and constant tension force is used for control, thus realizing even paving of the glass fiber.

Description

technical field [0001] The invention relates to a hollow composite insulator for high-voltage power transmission and transformation in the power industry, in particular to a hollow composite insulator for 1100kV combined electrical appliances and a manufacturing method thereof. Background technique [0002] After retrieving the relevant patent documents, the hollow composite insulator and its manufacturing method for 1100kV combined electrical appliances with the same structure as the present invention have not yet been retrieved. The existing power transmission and transformation insulators are mainly divided into two categories: porcelain sleeves made of porcelain materials and silicone rubber hollow composite insulators. The weight of the porcelain sleeve is heavy, and it is easy to damage other equipment after an explosion. The pollution resistance is low, the firing process is complicated, and the yield of large porcelain sleeves is low. Due to the high requirements fo...
