Abstract
The utility model relates to a circuit breaker current porcelain bushing applied on 330KV, which comprises a porcelain body and flanges arranged on two ends of the porcelain body. The circuit breaker current porcelain bushing is characterized in that the porcelain body is in an integral type, whose length is 1860mm, the appearance of the porcelain body is a cylindrical-shaped rotary body, the middle portion of the porcelain body is provided with a hollow portion, and the outer portion is provided with a big umbrella and a small umbrella, and the big umbrella and the small umbrella are arrayed at interval, and then, the circuit breaker current porcelain bushing has excellent mechanical intensity, excellent anti-pollution behaviour, high pollution grade, high pressure resistance and excellent dust-proof effect, which can be widely used in the industries such as mines, electric power, metallurgy, railway and the like.
Description
Technical field
Technical field under the utility model relates to a kind of electrical materials and appliances, specifically relates to the circuit breaker current insulator of a kind of 330KV of applying to.
Background technology
At present, relating to the circuit breaker current insulator that applies to the such voltage levels of 330KV mostly is to adopt organic (or inorganic) adhered, such circuit breaker current 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 specification requirement and instructions for use, also have the problem of the unreasonable structure of design in addition product.
Summary of the invention
Technical problem to be solved in the utility model provides the integral type circuit breaker current insulator of a kind of 330KV of satisfying high voltage requirement.
Technical solution adopted in the utility model is: the circuit breaker current insulator: 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 profile is conical revolving body, 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; The length of described porcelain body is 1860mm, and the diameter of hollow parts is 180mm, and the diameter of gamp is 478mm; The screw hole that it is 16.5mm that described ring flange is provided with 12 diameters.
Because the utility model has been taked above structure, make needs that just can satisfy the such voltage levels of 330KV of such circuit breaker current insulator, and have conveniently install, stability is strong, overall structure is rigorous, the characteristics of external insulation electric property and good mechanical property.
