Abstract
The utility model relates to a porcelain bushing for a 330KV lightning protector, which comprises a porcelain body and ring flanges at two ends thereof. The porcelain bushing is characterized in that the porcelain body is an integral part made of high alumina material; the ring flanges at two ends of the porcelain body are made of high-intensity aluminum casting alloy or hot dipping ductile iron; the porcelain body and the ring flanges are bonded through Portland cement adhesive larger than or equal to No.500; the length of the porcelain body is 1844mm; and the porcelain body adopts a shape of a column with a hollow structure arranged in the middle and big umbrella structures and small umbrella structures arranged at intervals at the external part. The utility model has the advantages of favorable mechanical strength, good pollution resistance, high dirtiness grade, and better high voltage resistant and dust proof effects, and can be widely applied in the industries such as mines, electrical power, metallurgy, railroads, etc.
Description
Technical field
Technical field under the utility model relates to a kind of electrical materials and appliances, specifically relates to the lightning arrester insulator of a kind of 330KV of applying to.
Background technology
At present, relating to what apply to the such voltage levels of 330KV mostly is to adopt organic (or inorganic) adhered, such lightning arrester insulator exists such shortcoming: bad mechanical property, bending strength is low, bonding position easy fracture, thereby influence the electric property of product, can not effectively satisfy specification requirement and instructions for use, also have the problem of the unreasonable structure of design in addition product.
Summary of the invention
Technical problem to be solved in the utility model provides the integral type lightning arrester insulator of a kind of 330KV of satisfying high voltage requirement.
Technical solution adopted in the utility model is: the lightning arrester insulator comprises the ring flange at porcelain body and porcelain body two ends; It is characterized in that: porcelain body is whole one, and described porcelain body is a high alumina refractories; The ring flange at described porcelain body two ends is divided into upper flange plate and lower flange, and ring flange is hollow; Ring flange is the spheroidal graphite cast-iron ring flange that high strength cast aluminium alloy or hot galvanizing are arranged; Porcelain body and ring flange are connected with 〉=550# portland cement adhesive mucilage binding; The total length of described insulator is 1844mm, and the porcelain body profile is cylindrical, has hollow parts in the middle of the porcelain body, and there is the structure of gamp and umbellule the outside, and gamp and umbellule are spaced; The diameter of described hollow parts is 145mm, and the gamp diameter is 349mm; Described ring flange height is 160mm, and the height that flange portions does not connect porcelain body is 80mm; The screw that it is 24mm that lower flange is provided with 4 diameters, upper flange plate are provided with the screw of 12 M10mm; The distance of center circle diameter of two screws by lower flange center of circle correspondence is 354mm, and the distance of center circle diameter of two screws by upper flange plate center of circle correspondence is 250mm.
Because the utility model has been taked above structure, make needs that just can satisfy the such voltage levels of 330KV of such lightning arrester insulator, and have conveniently install, stability is strong, overall structure is rigorous, the characteristics of external insulation electric property and good mechanical property.
