Abstract
The utility model relates to a lightning arrester high voltage porcelain bushing with 750 KV, which comprises a porcelain body and flanges on the two ends of the porcelain body, and is characterized in that the porcelain body is entire with the length of 1845mm, and a hollow structure which is provided with a large shed and a small shed on the outer side thereof is arranged on the middle portion of the porcelain body. Therefore, the lightning arrester high-voltage porcelain bushing with the structure has the advantages of excellent mechanical strength, high water pressure failure strength resistance and well electric property, and has good anti-pollution characteristic and high pollution class owing to adopting open type large and small sheds, can reach the favorable effects of high pressure resistance and dust prevention, and can be widely applied in industries of mine, electrical power, metallurgy, railway and the like.
Description
Technical field
Technical field under the utility model relates to a kind of electrical materials and appliances, specifically relates to the lightning arrester high voltage porcelain bushing of a kind of 750KV of applying to.
Background technology
At present, relating to the lightning arrester high voltage porcelain bushing that applies to the such voltage levels of 750KV mostly is that employing is adhered, such lightning arrester high voltage porcelain bushing 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 high voltage porcelain bushing of a kind of 750KV of satisfying high voltage requirement.
Technical solution adopted in the utility model is; The lightning arrester high voltage porcelain bushing comprises the ring flange at 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; The length of described porcelain body is 1845mm; Also has the structure that there are gamp and umbellule in hollow parts, an outside in the middle of the described porcelain body; Described gamp and umbellule are spaced; The diameter of described hollow parts is 238mm; Described gamp diameter is 492mm.
Because the utility model taked above structure, make needs that just can satisfy the such voltage levels of 750KV of such lightning arrester high voltage porcelain bushing, and have conveniently install, stability by force, overall structure is rigorous, insulation effect is good characteristics.
