Abstract
The utility model discloses a wire outlet composite bushing, which comprises a hollow insulator, a conductor, a screening and a lower flange, wherein the lower flange is fixedly connected with the lower end of the hollow insulator, the screening is of a single-layer screening, the screening is arranged in the hollow insulator, and the lower end of the screening is fixed on the lower flange. The lower flange of the wire outlet composite bushing integrates the functions of butting of connecting ports, fixture of the hollow insulator and inner shielding installation and the like, is simple in structure, excellent in high pressure resistance, does not need to filter a tank body, and can bear 145KV voltage and below.
Description
Technical field
The utility model relates to a kind of high-voltage electrical apparatus assembly, particularly a kind of outlet composite bushing.
Background technology
The insulator of existing 145kV sleeve pipe mostly is insulator, and volume is large, Heavy Weight, and cost is high, and the dirty grade of resistant is low, and external form is attractive in appearance not, with the interface of high-voltage switch gear, mostly is transition tank, actual production and field installation process trouble, production efficiency is low, and the production cycle is long.
Also have a kind of high-pressure composite sleeve, it comprises terminal block, top board, hollow insulator, double layer screen, lower flange, conducting rod and transitional shell, complex structure.
The utility model content
The technical problems to be solved in the utility model is: a kind of composite bushing of the outlet without transition tank is provided.
In order to solve the problems of the technologies described above, the utility model comprises hollow insulator, conductor, shielding and lower flange, and described lower flange is fixedly connected with the lower end of hollow insulator, and described shielding is single-layer shield, shielding is arranged in hollow insulator, and the lower end of shielding is fixed on lower flange.
Described lower flange comprises connecting ring and air chamber, and connecting ring is around the middle and lower part that is fixed on air chamber, and the height of air chamber is greater than the thickness of connecting ring, and air chamber is up-small and down-big body, and shielding and hollow insulator are all fixed with the upper end of air chamber.
The beneficial effects of the utility model are: lower flange set of the present utility model connector docking, hollow insulator fix and the functions such as installation of inner shield, simple in structure, barotolerance is good, does not need to filter tank body, can bear 145KV and following voltage.
