Abstract
The utility model relates to a high-voltage electric porcelain, particularly relates to a porcelain bushing of a lightning arrester. The porcelain bushing of the lightning arrester comprises a porcelain body and flanges at the two ends of the porcelain body, wherein the porcelain is integral, and the flanges are arranged at the two ends of the porcelain body; the porcelain bushing is characterized in that the length of the porcelain body is 1734mm; a hollow part with the diameter of 175mm is arranged in the middle of the porcelain body; the diameter of the porcelain body is 275mm; a large umbrella and a small umbrella are respectively arranged at the two ends of the porcelain body; the diameter of the large umbrella is 415mm; and the diameter of the small umbrella is 375mm. Owing to the adoption of the above structure, the porcelain bushing of the lightning arrester has the characteristics that: the creepage distance is equal to or more than 6000mm, and the bending and breaking load test stress reaches107KN.m; and the porcelain bushing of the lightning arrester has also has the characteristics of having simple structure, strong stability and good insulating effect, and being convenient to install.
Description
Technical field
Technical field under the utility model relates to a kind of high tension insulator, specifically relates to a kind of lightning arrester insulator.
Background technology
At present, relate to the strut porcelain bushing that applies to voltage levels and on design size, have many un-reasonable phenomenons mostly, cause strut porcelain bushing on bending resistance load routine test stress distance, bending strength, creepage distance, not reach requirement, perhaps combination property does not reach requirement, perhaps waste raw material, perhaps oversize etc., be difficult to satisfy actual needs.
Summary of the invention
The purpose of this utility model will provide a kind of high voltage requirement of satisfying exactly, and all meets the requirements of strut porcelain bushing on bending resistance load routine test stress distance, bending strength, creepage distance.
Technical solution adopted in the utility model is: a kind of lightning arrester insulator, the flange that comprises porcelain body and porcelain body two ends, described porcelain body is whole one, described porcelain body two ends are equipped with flange, it is characterized in that: the length of described porcelain body is 1734mm, the hollow parts that it is 175mm that the porcelain body centre has a diameter, the diameter of porcelain body is 275mm, the two ends of porcelain body have a gamp and a umbellule respectively, and described gamp diameter is 415mm, and the diameter of umbellule is 375mm.
The novel beneficial effect of this use is: because the utility model has been taked above structure, make such lightning arrester insulator have: creepage distance 〉=6000mm, and bending resistance destroys load test stress and reaches 107KN.m; Also have characteristics simple in structure, that convenience is installed, stability is strong, insulation effect is good.
