Abstract

The invention provides a preparation technology of a composite porcelain insulator. 18 to 25 parts of epoxy resin, 20 to 30 parts of glass fibers, 10 to 15 parts of nylon, 5 to 12 parts of boron nitride, 3 to 5 parts of curing agent, 1 to 3 parts of accelerant, 3 to 5 parts of flame retardant and 1 to 3 parts of release agent are reasonably and scientifically matched and are poured to obtain a insulator prototype; substances with high mechanical properties such as the glass fibers, the nylon, quartz sand and boron nitride are reasonably matched, so that the mechanical properties of porcelain insulators are greatly improved; by adding a proper flame retardant, the composite porcelain insulator has good flame retardancy; the mechanical strength of the rod core is enhanced by optimizing the preparation process of the rod core; by spraying and coating a layer of self-cleaning coating on the outer surface of the porcelain insulator, better pollution flashover resistance is realized; compared with the traditional porcelain insulator, the composite porcelain insulator prepared technology disclosed by the invention has the characteristics of high mechanical properties, safety, reliability,pollution flashover resistance and the like.

Description

technical field [0001] The invention relates to a manufacturing process of an insulator, in particular to a manufacturing process of a composite porcelain insulator. Background technique [0002] Insulator is a special insulation control, which is widely used in overhead transmission and distribution line terminals, tension and corner poles, and plays the role of insulating and fixing wires. Its reasonable application plays an important role in the safe operation of transmission lines. With the development of EHV / UHV large-capacity transmission technology, insulators are required to have high-quality mechanical strength, safety, anti-pollution flashover and other functions. Traditional insulators are mostly porcelain insulators, which can no longer meet the needs of modern power work due to their bulkiness, ease of cleaning, easy pollution flashover accidents, and difficult maintenance. Therefore, the development of porcelain insulators with high mechanical strength, safety...
