Abstract
The utility model relates to a base porcelain bushing of lightning arrester, which is used in 800kV. The base porcelain bushing of lightning arrester comprises a porcelain body and flange plates on two ends of the porcelain body. The base porcelain bushing of lightning arrester is characterized in that the porcelain body is a whole and is made of high alumina materials, the flange plates on two ends of the porcelain body are high-intensity aluminum cast alloy or hot galvanizing nodular graphite cast iron flange plates, the porcelain body and the flange plates are packaged through using Portland cement glue bigger than or equal to No.500, the porcelain body has fixed size and structure, and the porcelain bushing can satisfy high voltage grade demands of 800kV. The base porcelain bushing of lightning arrester is characterized in that the installation is convenient, the stability is strong, the integral structure is precise, and the insulating effect is good.
Description
Technical field
Technical field under the utility model relates to a kind of electrical materials and appliances, specifically relates to the porcelain bushing for lightning protector base of a kind of 800KV of applying to.
Background technology
At present, relating to the porcelain bushing for lightning protector base that applies to the such voltage levels of 800KV mostly is to adopt organic (or inorganic) adhered, such porcelain bushing for lightning protector base 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 off size reason in addition and influence the problem of properties of product product.
Summary of the invention
Technical problem to be solved in the utility model provides the integral type porcelain bushing for lightning protector base of a kind of 800KV of satisfying high voltage requirement.
Technical solution adopted in the utility model is: porcelain bushing for lightning protector base: the ring flange that comprises porcelain body and porcelain body two ends, it is characterized in that: the length of porcelain bushing for lightning protector base is 1222～1226mm, porcelain body is whole one, described porcelain body is a high alumina refractories, and the ring flange at described porcelain body two ends is measure-alike; Ring flange has the spheroidal graphite cast-iron ring flange of high strength cast aluminium alloy or hot galvanizing; Porcelain body is connected with being not less than 500# portland cement adhesive mucilage binding with ring flange; Described porcelain body profile is: have the cylinder that gamp and umbellule structure, bosom have hollow parts in the middle of outside; The diameter of described hollow parts is 315～325mm, and removing umbrella leaf cylinder external diameter is 375～385mm, and the gamp diameter is 520mm, and the umbellule diameter is 490mm, and gamp and umbellule are alternately arranged.
Because the utility model has been taked above structure, make needs that just can satisfy the such voltage levels of 800KV of such porcelain bushing for lightning protector base, and have conveniently install, stability is strong, overall structure is rigorous, the characteristics of external insulation electric property and good mechanical property.
