Abstract
The utility model relates to a 220 kV lower post porcelain bushing, which comprises a porcelain body and flanges at two ends of the porcelain body, and is characterized in that the porcelain body is integrated, a hollow structure is arranged in the middle of the porcelain body while big sheds and small sheds are arranged outside the porcelain body, and the big sheds and the small sheds are arranged at intervals. Therefore, the 220 kV lower post porcelain bushing has the advantages of simple structure, high mechanical strength, high breaking strength of internal water pressure and fine electrical performance. Since the 220 kV lower post porcelain bushing adopts the open type big sheds and small sheds, the porcelain bushing has fine stain resistance and a high antifouling level.
Description
Technical field
Technical field under the utility model relates to a kind of high tension insulator, specifically relates to a kind of 220kV of applying to lower supporting rod insulator.
Background technology
At present, relating to the insulator that applies to the such voltage levels of 220kV mostly is to adopt organic (or inorganic) adhered, such 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 the specification requirement of user product, also have in addition design unreasonable structure influence the problem of practical function.
Summary of the invention
Technical problem to be solved in the utility model provides the 220kV lower supporting rod insulator of a kind of 220kV of satisfying high voltage requirement.
Technical solution adopted in the utility model is: 220kV lower supporting rod insulator, comprise the ring flange at porcelain body and porcelain body two ends, and it is characterized in that: porcelain body is whole one, the ring flange at porcelain body and porcelain body two ends is with No. 925 cementitious being in the same place; The length of described porcelain body is 1280mm; The height of the ring flange at described porcelain body two ends is 135mm; Have a hollow parts in the middle of the described porcelain body, the diameter of its hollow parts is 174mm-188mm; Described porcelain body outside has the structure of gamp and umbellule, and gamp and umbellule are spaced, and gamp and umbellule adopt open umbellate form; Described gamp diameter is 406mm, and the diameter of umbellule is 362mm.
The novel beneficial effect of this use is: because the utility model has been taked above structure, make such 220kV lower supporting rod insulator have: creepage distance 〉=6200mm, bending resistance destroys load 〉=56KN.m, interior hydraulic pressure destroys the specification requirement of load 〉=3.7Mpa, can satisfy the needs of 220kV voltage levels.
The structure of the 220kV lower supporting rod insulator that it is such has the advantages that convenience is installed, stability is strong, overall structure is rigorous, insulation effect is good.
