Abstract
The invention relates to a porcelain bushing for a lightning protector base of 800KV. The porcelain bushing for the lightning protector base comprises a porcelain body and flange plates arranged at two ends of the porcelain body. The porcelain bushing for the lightning protector base is characterized in that the porcelain body is a whole body and is made of high aluminum materials; the flange plates at 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 and connected by using silicate cement glue of more than or equal to No.500; and the porcelain body has fixed size and structure. Therefore, the porcelain bushing can meet the requirement of high voltage grade such as 800KV, and has the characteristics of convenient assembly, strong stability, compact integral structure and good insulating effect.
Description
Technical field
Technical field under the present invention 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 by this invention provides the integral type porcelain bushing for lightning protector base of a kind of 800KV of satisfying high voltage requirement.
The technical solution used in the present invention 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 1477～1481mm, 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 present invention has 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.
