Abstract
The utility model relates to a porcelain bushing for a 110KV 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 320mm; and the porcelain body takes the shape of a column with a hollow structure arranged in the middle and a big umbrella structure arranged 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 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 structure of design and the problem of off size reason 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, comprise the ring flange at porcelain body and porcelain body two ends, and 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, ring flange are the spheroidal graphite cast-iron ring flanges that high strength cast aluminium alloy or hot galvanizing are arranged, and porcelain body and ring flange are connected with 〉=500# portland cement adhesive mucilage binding; Ring flange is provided with the screw hole for connection, and the end face that is provided with screw hole is the flange butt plate, and the flange butt plate is divided into upper flange butt plate and lower flange butt plate; The length of described porcelain body is 288mm, and described porcelain body profile is cylindrical, and the centre has hollow parts, and there is the gamp structure outside; The diameter of described hollow parts is 100mm, and the gamp diameter is 274mm; Described ring flange height is 95mm, the thickness of flange butt plate is 16mm, the screw hole that it is 14mm that the flange butt plate is provided with 4 diameters, the distance of center circle diameter in the two-screw hole by upper flange butt plate center of circle correspondence is 276mm, and the distance of center circle diameter in the two-screw hole by lower flange butt plate center of circle correspondence is 270mm; The rated voltage of described lightning arrester insulator is 110KV, and bending moment is destroyed and is not less than 12kN.m.
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.
