Abstract
The invention relates to a high voltage porcelain bushing of breaker, which is applied to 500KV and comprises a porcelain body and flange discs at two ends of the porcelain body; the invention is characterized in that the porcelain body is an integral, 2060mm in length, cylindrical in appearance, hollow at center, and provided with large and small umbrella structure; the large umbrellas and small umbrellas are arranged at intervals; the above high voltage porcelain bushing of breaker has good mechanical strength, good stain resistance and high pollution level, can achieve better high pressure resistant and dustproof effects, and can be widely applied in industries such as mine, power, metallurgy, railway and the like.
Description
Technical field
Technical field under the present invention relates to a kind of electrical materials and appliances, specifically relates to the high voltage porcelain bushing of breaker of a kind of 550KV of applying to.
Background technology
At present, relating to the high voltage porcelain bushing of breaker that applies to the such voltage levels of 500KV mostly is to adopt organic (or inorganic) adhered, such high voltage porcelain bushing of 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 the problem of off size reason in addition product.
Summary of the invention
Technical problem to be solved by this invention provides the integral type high voltage porcelain bushing of breaker of a kind of 500KV of satisfying high voltage requirement.
The technical solution used in the present invention is: high voltage porcelain bushing of breaker, the ring flange that comprises porcelain body and porcelain body two ends, it is characterized in that: described porcelain body is whole one, described porcelain body profile is cylindrical, the centre has hollow parts, there are gamp and umbellule structure in the outside, and gamp and umbellule are spaced; The ring flange at described porcelain body two ends is circular, and the two ends ring flange is measure-alike; The length of porcelain body is 2060mm; The diameter of described hollow parts is 205mm, and the diameter of described gamp is 425mm, the screw hole that it is 18mm that described ring flange is provided with 8 diameters.
Because the present invention has taked above structure, make needs that just can satisfy the such voltage levels of 500KV of such high voltage porcelain bushing of breaker, and have conveniently install, stability is strong, overall structure is rigorous, the characteristics of external insulation electric property and good mechanical property.

Embodiment
The invention will be further described below in conjunction with accompanying drawing.
High voltage porcelain bushing of breaker: the ring flange 2 that comprises porcelain body 1 and porcelain body 1 two ends, it is characterized in that: described porcelain body 1 is whole one, and porcelain body 1 profile is cylindrical, and the centre has hollow parts 5, there are gamp 3 and umbellule 4 structures in the outside, and gamp 3 and umbellule 4 are spaced; The ring flange 2 at described porcelain body 1 two ends is circular, and two ends ring flange 2 is measure-alike; The long H of described porcelain body 1 is 2060mm; The diameter d 1 of described hollow parts 5 is 205mm, and the diameter D of described gamp 3 is 425mm; The screw hole 6 that it is 18mm that described ring flange 2 is provided with 8 diameters.
Such high voltage porcelain bushing of breaker has good mechanical strength, hydraulic pressure breakdown strength and good electric property, and umbellate form adopts open big umbellule, and anti-pollution characteristic is good, the gradation for surface pollution height, high pressure resistant, dustproof better effects can be widely used in the industries such as mine, electric power, metallurgy, railway.
