Abstract

A composite bushing includes a compression ring, an insulator and a support bus, and is characterized in that the insulator is a hollow composite insulator, an inner shielding device is arranged in the cavity of the hollow composite insulator, and the support bus is arranged at the lower part of the hollow composite insulator. The utility model has the advantages of excellent explosion prevention performance, insulating quality and mechanical property, and the insulator is hard to break during the installation; and the double shield of intermediate potential and ground potential are added, thereby improving the distribution of the electric field outside the bushing, and enhancing the external insulating power of the bushing.

Description

Composite bushing
Technical field
The utility model relates to the high voltage electric equipment technical field, particularly a kind of composite bushing.
Background technology
Sleeve pipe is mainly used in drawing of outdoor high-voltage power transmission and transforming equipment turnover line, or being connected of high-tension power transmission and transformation equipment and overhead transmission line, the conducting electric current, realize the transition of galvanic circle between gas-insulated medium and air insulation medium, it is poor that at present the sleeve pipe that uses exists explosion-proof, insulating properties, mechanical property, the shortcoming of insulator cracky in the installation.
Summary of the invention
The purpose of this utility model provides a kind of 1100KV of being applicable to electrical network, and explosion-proof, insulating properties, mechanical property are good, the composite bushing that cost is low.
The utility model is achieved in that it comprises pressure ring, insulator and support bus, it is characterized in that insulator is a hollow combined insulator, is provided with internal screening device in the hollow combined insulator chamber, is provided with the support bus in the bottom of hollow combined insulator.
The utility model has the advantages that explosion-proof, insulating properties, mechanical property are good, insulator cracky not in the installation; Set up intermediate potential and earthing potential dual shield, improved the sleeve pipe distribution of external electric field, strengthened the external insulation ability of sleeve pipe.
