The strut porcelain bushing of sulfur hexafluoride circuit breaker is characterized in that the porcelain body is a whole and is made of high alumina materials, the flange plates on the ends of the porcelain body are high-intensity aluminum cast alloy or hot galvanizing nodular graphite cast iron flange plates, the porcelain body and the flange plates are packaged through using Portland cement glue bigger than or equal to No.500, the porcelain body, the upper flange plate on the upper end of the porcelain body and the lower flange plate on the lower end have fixed size and structures, and strut porcelain bushing of sulfur hexafluoride circuit breaker can satisfy high voltage grade demands of 110Kv. The strut porcelain bushing of sulfur hexafluoride circuit breaker is characterized in that the installation is convenient, the stability is strong, the integral structure is precise, and the insulating effect is good.
Description
Technical field
Technical field under the utility model relates to a kind of electrical materials and appliances, specifically relates to the strut porcelain bushing of sulfur hexafluoride circuit breaker of a kind of 110KV of applying to.
Background technology
At present, relating to the strut porcelain bushing of sulfur hexafluoride circuit breaker that applies to the such voltage levels of 110KV mostly is to adopt organic (or inorganic) adhered, such strut porcelain bushing of sulfur hexafluoride circuit breaker 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 strut porcelain bushing of sulfur hexafluoride circuit breaker of a kind of 110KV of satisfying high voltage requirement.
Technical solution adopted in the utility model is: strut porcelain bushing of sulfur hexafluoride circuit breaker: 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 strut porcelain bushing of sulfur hexafluoride circuit breaker is 1397～1403mm; Described porcelain body profile is: outside centre has gamp and umbellule structure, bosom have the hollow parts cylinder; Described gamp diameter is 365mm, and the umbellule diameter is 335mm, 13 of 14 of gamps and umbellules, and gamp and umbellule are alternately arranged, and the cylindrical diameter of hollow parts is 150mm; Described ring flange height is 110mm, and the diameter of the hollow parts of ring flange is 255mm, and external diameter is 360mm, and ring flange is provided with 12 diameters and is uniformly distributed on the circle that diameter is 330mm for the 14mm screw hole.
Because the utility model has been taked above structure, make needs that just can satisfy the such voltage levels of 110KV of such strut porcelain bushing of sulfur hexafluoride circuit breaker, and have conveniently install, stability is strong, overall structure is rigorous, the characteristics of external insulation electric property and good mechanical property.
