Abstract
The utility model relates to a porcelain lightning arrester bushing applied to 110kV. The porcelain lightning arrester bushing comprises a porcelain body and flanges arranged on both ends of the porcelain body. The porcelain lightning arrester bushing has the following characteristics: the porcelain body is integrated; the porcelain body is made of high alumina material; the flanges on both ends of the porcelain body are ductile cast iron flanges which are made of high-strength cast aluminium alloy or hot-dip galvanized; the porcelain body and the flanges are bound together by adopting portland cement adhesive equal to or larger than No.500; the porcelain body is 1331mm long; the porcelain body is shaped like a cylinder; the middle of the porcelain body is hollow; a structure of large and small umbrellas is arranged on the outside of the porcelain body; the large and the small umbrellas are arranged at intervals; consequently, the porcelain lightning arrester bushing has the advantages of good mechanical strength, good stain-resistant performance and high pollution grade; and the porcelain lightning arrester bushing can have good high-voltage-resistant and dust-proofing effects and can be widely used in industries such as mines, electric power, metallurgy and railways.
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 110KV of applying to.
Background technology
At present, relating to what apply to the such voltage levels of 110KV 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 110KV 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 〉=500# portland cement adhesive mucilage binding; The length of described porcelain body is 1331mm, 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 124mm, and the gamp diameter is 304mm; Described ring flange height is 120mm, and the height that flange portions does not connect porcelain body is 33mm; The screw that it is 14mm that lower flange is provided with 4 diameters, upper flange plate are provided with the screw of 8 8mm; The distance of center circle diameter of two screws by lower flange center of circle correspondence is 276mm, and the distance of center circle diameter of two screws by upper flange plate center of circle correspondence is 229mm.
Because the utility model has been taked above structure, make needs that just can satisfy the such voltage levels of 110KV 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.
