Abstract
The invention relates to a compound porcelain sleeve for a 350 KV lightning arrester, comprising a porcelain body and ring flanges positioned on both ends of the porcelain body. The compound porcelain sleeve is characterized in that the porcelain body is an integer and has the length of 802 mm; the middle of the porcelain body is also provided with a hollow part, and a large umbrella structure and a small umbrella structure are arranged outside the porcelain body. The compound porcelain sleeve for the 350 KV lightning arrester has good mechanical strength, high water pressure breaking strength resistance and good electrical property and adopts an umbrella form of open type large and small umbrellas, thereby having good pollution resistance and high pollution class; in addition, the invention can achieve the better effects of high voltage resistance and dust prevention and be widely used for industries, such as mines, electricity, metallurgy, railways, and the like.
Description
Technical field
Technical field under the present invention relates to a kind of electrical materials and appliances, specifically relates to the compound porcelain sleeve for lightning arrester of a kind of 350KV of applying to.
Background technology
At present, relating to the compound porcelain sleeve for lightning arrester that applies to the such voltage levels of 350KV mostly is that employing is adhered, such compound porcelain sleeve for lightning arrester 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 by this invention provides the integral type compound porcelain sleeve for lightning arrester of a kind of 350KV of satisfying high voltage requirement.
The technical solution used in the present invention is; Compound porcelain sleeve for lightning arrester 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 802mm; 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 85mm; Described gamp diameter is 250mm.
Because the present invention taked above structure, make needs that just can satisfy the such voltage levels of 350KV of such compound porcelain sleeve for lightning arrester, and have conveniently install, stability by force, overall structure is rigorous, insulation effect is good characteristics.
