Abstract
The utility model relates to a porcelain bushing for a 500KV lightning protector, which comprises a porcelain body and ring flanges arranged 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 500; the length of the porcelain body is 320mm; the porcelain body adopts a shape that an umbrella structure is arranged at the outer middle part; the upper ring flange is provided with a round coupling flange on one side of the main body of the ring flange, and the main body of the ring flange and the coupling flange are integrated through the connection of strengthening ribs; and the lower ring flange is provided with a round coupling flange on one side of the main body of the ring flange, and the main body of the ring flange and the coupling flange are integrated through the connection of strengthening ribs. The porcelain bushing can satisfy the requirement of the high voltage grade as 500KV, and has the advantages of convenient installation, high stability, compact integral structure and excellent insulation effect.
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 500KV of applying to.
Background technology
At present, relating to the lightning arrester insulator that applies to the such voltage levels of 500KV 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 to product, also have the structure of design and off size reason in addition and influence the problem of properties of product, particularly no reinforcement is connected between the main body of ring flange and the terminal pad, has caused ring flange fragile.
Summary of the invention
Technical problem to be solved in the utility model provides the integral type lightning arrester insulator of a kind of 500KV of satisfying high voltage requirement.
Technical solution adopted in the utility model is: the lightning arrester insulator: the ring flange that comprises porcelain body and porcelain body two ends, it is characterized in that: porcelain body is whole one, described porcelain body is a high alumina refractories, and the ring flange at described porcelain body two ends is divided into upper flange plate and lower flange; Ring flange is the ring flange with spheroidal graphite cast-iron 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, and the length of whole lightning arrester insulator is 400mm; Described porcelain body profile is: the structure, the umbrella that have a umbrella leaf in the middle of outside directly are 414mm; Bosom has the cylinder that diameter is the hollow parts of 160mm; Described upper flange plate height is 141mm, upper flange plate has the terminal pad of the circle of ring flange main body one side, ring flange main body and terminal pad are to have an integrative-structure that reinforcement is connected, at the screw that 4 34mm are arranged on the 484mm diameter with upper flange plate terminal pad center; Described lower flange height is 141mm, and lower flange has the terminal pad of the circle of ring flange main body one side, and ring flange main body and terminal pad are to have an integrative-structure that reinforcement is connected, at the screw that 4 34mm are arranged on the 484mm diameter with ring flange terminal pad center.
Because the utility model has been taked above structure, make needs that just can satisfy the such voltage levels of 500KV 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.
