Abstract

The invention discloses a gas wall bushing which comprises a tank body connection part and two wire inlet and outlet bushings. Two wire inlet and outlet bushings are respectively arranged inside and outside a wall body and are abutted by the tank body connection part; the tank body connection part comprises a metal shell, a basin-type insulator, a contact pedestal and a tank body middle conductor;a first mounting flange, a second mounting flange, a density relay and an explosion-proof device are arranged on the metal shell; the tank body connection part is fixed on the wall body by the firstmounting flange and the second mounting flange; each wire inlet and outlet bushing comprises an equalizing ring, a composite hollow insulator, a bushing middle conductor and a bushing shield; the bushing middle conductors are abutted in a positioning mode with the tank body middle conductor by the contact pedestal, and conductor through flow is met by a contact finger spring in the contact pedestal. According to the invention, problems of local discharge, dielectric property, heat resistance and the like of a capacitive-type wall bushing can be effectively solved, moreover, the gas wall bushing is simple in structure and convenient to mount and disassemble, efficiency is greatly improved, and both time and labor are saved.

Description

technical field [0001] The invention relates to a gas wall bushing, which belongs to the technical field of electric equipment. Background technique [0002] Since the wall casing equipment has been put into practical use, it has been widely used all over the world. At present, with the rapid development of my country's electric power construction, wall bushings are not only widely used in the fields of AC and DC high voltage and ultra-high voltage, but also in the field of AC and DC UHV. The extensive use of wall-piercing bushing equipment has increased the market development and use of different structural types of bushings. At present, most of the structural types of wall-piercing bushings are capacitive structures, but the methods used are different, such as oil-soaked paper, glue, etc. Adhesive paper, glue-impregnated paper, etc., this structure currently has problems that are difficult to solve in terms of partial discharge, dielectric properties, and heat resistance....
