Description

Circuit breaker base insulator

Technical field

Technical field under the utility model relates to a kind of electrical materials and appliances, specifically relates to the circuit breaker base insulator of a kind of 220KV of applying to.

Background technology

At present, relating to the circuit breaker base insulator that applies to the such voltage levels of 220KV mostly is to adopt organic (or inorganic) adhered, such circuit breaker base 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 structure of design and the problem of off size reason in addition product.

Summary of the invention

Technical problem to be solved in the utility model provides the integral type circuit breaker base insulator of a kind of 220KV of satisfying high voltage requirement.

Technical solution adopted in the utility model is: circuit breaker base insulator, the ring flange that comprises porcelain body and porcelain body two ends, it is characterized in that: described porcelain body is whole one, the 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 ring flange is divided into upper flange plate and lower flange; The length of porcelain body is 1340mm; The diameter of described hollow parts is 121mm, and the diameter of described gamp is 340mm; The screw hole that it is 18mm that the screw hole that it is 14mm that upper flange plate is provided with 12 diameters, lower flange are provided with 8 diameters.

Because the utility model has been taked above structure, make such needs that just can satisfy the such voltage levels of 220KV of circuit breaker base insulator, and have conveniently install, stability is strong, overall structure is rigorous, the characteristics of external insulation electric property and good mechanical property.
