Abstract
The utility model relates to a porcelain bushing for an 800KV 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 adopt the same size and structure; the porcelain body and the ring flanges are bonded through Portland cement adhesive larger than or equal to No.500; the porcelain body adopts a shape that an umbrella structure is arranged at the outer middle part, and a hollow cylinder is arranged at the inner middle part; each ring flange is provided with a ring flange main body and a flange connection disc positioned on one side of the ring flange main body, and the flange connection disc and the ring flange main body are combined as a whole through additionally arranged strengthening ribs. The porcelain bushing can satisfy the requirement of the high voltage grade as 800KV, 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 porcelain bushing for lightning protector base of a kind of 800KV of applying to.
Background technology
At present, relating to the porcelain bushing for lightning protector base that applies to the such voltage levels of 800KV mostly is to adopt organic (or inorganic) adhered, such porcelain bushing for lightning protector base 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 porcelain bushing for lightning protector base of a kind of 800KV of satisfying high voltage requirement.
Technical solution adopted in the utility model is: porcelain bushing for lightning protector base: 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 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 porcelain bushing for lightning protector base is 408～412mm; Described porcelain body profile is: have the structure of a umbrella leaf, the cylinder that bosom has hollow parts in the middle of outside; Described ring flange comprises ring flange main body and flange terminal pad, and the flange terminal pad is positioned at a side of ring flange main body, and increasing reinforcement between flange terminal pad and the ring flange main body is one also.
Because the utility model has been taked above structure, make needs that just can satisfy the such voltage levels of 800KV of such porcelain bushing for lightning protector base, and have conveniently install, stability is strong, overall structure is rigorous, the characteristics of external insulation electric property and good mechanical property.
