Abstract
The utility model relates to an arrestor porcelain bushing, which is applied on 330KV, and comprises a porcelain body and flanges arranged on two ends of the porcelain body. The arrestor porcelain bushing is characterized in that the porcelain body is in an integral type, whose length is 1824mm, the middle portion of the porcelain body is further provided with a hollow structure, and the outside is provided with a big umbrella and a small umbrella, and then, the arrestor porcelain bushing has excellent mechanical intensity, high water-pressure resistance collapsing strength and excellent electrical performance. The umbrellas adopt an opened-type big umbrella and a small umbrella. The arrestor porcelain bushing has excellent anti-pollution behaviour and high pollution grade, can reach better effects of high pressure resistance and dust prevention, and can be widely used in the industries such as mines, electric 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 a kind of lightning arrester insulator of a kind of 330KV of applying to.
Background technology
At present, relating to a kind of lightning arrester insulator that applies to the such voltage levels of 330KV mostly is that employing is adhered, a kind of lightning arrester insulator like this 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 a kind of lightning arrester insulator of integral type of a kind of 330KV of satisfying high voltage requirement.
Technical solution adopted in the utility model is; A kind of lightning arrester insulator 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 1824mm; 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 145mm; Described gamp diameter is 365mm.
Because the utility model taked above structure, make such needs that just can satisfy the such voltage levels of 330KV of a kind of lightning arrester insulator, and have conveniently install, stability by force, overall structure is rigorous, insulation effect is good characteristics.
