Abstract
The utility model relates to a porcelain sleeve for a 110KV lightning arrester, which comprises a porcelain body and flanges arranged on two ends of the porcelain body, and is characterized in that the porcelain body is integrative; the porcelain body is of a high aluminum material; the flanges arranged on two ends of the porcelain body are the flanges made of high strength cast aluminum alloy or hot galvanized ductile cast iron; the porcelain body is connected with the flanges by applying No. 500 or over No. 500 silicate cement cementing agent; the porcelain body, the upper flange arranged on the upper end of the porcelain body and the lower flange arranged on the lower end of the porcelain body are provided with a fixed dimension and a fixed structure; and the height of the flange is 100mm, a sunk part is arranged on the flange on the other side which contacts the porcelain body, and an opening is arranged on the side of the sunk part. The porcelain sleeve for a sulfur hexafluoride breaker can meet the requirement of 110KV high voltage class, and has the advantages of convenient installation, strong stability, compact integral structure and good 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 110KV of applying to.
Background technology
At present, relating to the lightning arrester insulator that applies to the such voltage levels of 110KV 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, 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 in the utility model provides the integral type lightning arrester insulator of a kind of 110KV of satisfying high voltage requirement.
Technical solution adopted in the utility model is: the lightning arrester insulator: comprise the ring flange at porcelain body and porcelain body two ends, it is characterized in that: porcelain body is whole one, and described porcelain body is a high alumina refractories, and the ring flange at described porcelain body two ends is that size is identical with structure; 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 1365mm; Described porcelain body profile is: outside centre has gamp and umbellule structure, bosom have the hollow parts cylinder; Described gamp diameter is 280mm, and the umbellule diameter is 225mm, 16 of 16 of gamps and umbellules, and gamp and umbellule are alternately arranged, and the cylindrical diameter of hollow parts is 80mm; Described ring flange height is 100mm, also has sunk part at the opposite side ring flange that contacts with porcelain body, and the sunk part sidepiece also has opening.
Because the utility model has been taked above structure, make one of such lightning arrester insulator just can satisfy the needs of the such voltage levels of 110KV and the demand in special place, and have convenient install, stability is strong, overall structure is rigorous, the characteristics of external insulation electric property and good mechanical property.
