Abstract
The utility model discloses an oil and gas bushing structure for a non-segregated type GIS and belongs to the field of GIS equipment technology. The oil and gas bushing structure comprises a shell; one end of the shell is connected with a transformer and the other end is provided with an enclosed type disk insulator; the disk insulator is connected with a fixed conductor in the shell; a detachable conductor group is connected to the fixed conductor; and the detachable conductor group is connected with a high voltage bushing extended out from the transformer. The oil and gas bushing structure for the non-segregated type GIS has the advantages that fewer shells and inner conductors are required, so that the lap joint transitions of the conductors are reduced greatly and the electrical performance is greatly improved. The detachable conductor group can be installed and detached conveniently and thus the installation of the oil and gas bushing structure is more simple and convenient.

Utility model content
The purpose of this utility model is to provide a kind of box GIS oil-gas casing structure altogether, and this structure conductor overlap joint is simple, can reduce the use of connecting circuit element, effectively promotes the electric property of GIS oil-gas casing.
The utility model is to be achieved through the following technical solutions:
A kind of box GIS oil-gas casing structure altogether, comprise housing, one end of described housing is connected with transformer, the other end is provided with case type disk insulator, disk insulator is connected with the fixed conductor being arranged in housing, on fixed conductor, be connected with detachable conductor group, the bushing that detachable conductor group is stretched out with transformer is connected.
Described detachable conductor group comprises angle conductor, jointing, conductive seat and radome, jointing is connected with fixed conductor by angle conductor, conductive seat and jointing are by being arranged on the spring touch finger conducting in jointing, one end of radome is connected with conductive seat, and the bushing that the other end stretches out with transformer is connected.
The end that described housing is connected with transformer is provided with GIS flange, and on GIS flange, is evenly equipped with three circular ports that dock with transformer.
One end that described housing is connected with transformer also arranges the insulating element being made up of insulating flange and insulating case.
Described GIS flange is connected with transformer flange by insulating flange, and insulating case is arranged between GIS flange and insulating flange.
On described housing, also offer the operation handlebar mouth for detachable conductor group is installed.
Compared with prior art, the utlity model has following useful technique effect:
Box GIS oil-gas casing structure altogether of the present utility model, housing is connected with transformer terminal, the housing of this common box type is compared with existing three-phase separate box oil-gas casing structure, sheathing material reduces, the shell of common box type also makes the connection sealing surface between housing reduce, and then the probability of equipment gas leakage, the SF of enclosure interior are simultaneously reduced
6gas flow also greatly reduces; Meanwhile, adopt detachable conductor group structure, enclosure interior number of conductors is reduced, saved the middle components and parts that connect greatly than the structure of three-phase combined type, greatly reduced the transition overlap joint of conductor, electric property is improved greatly.
Further, oil-gas casing structure of the present utility model arranges insulating element between oil-gas casing and transformer, can realize the insulation between GIS housing and transformer shell.
Further, on housing, offer operation handlebar mouth, can easily detachable conductor group be installed, be dismantled, oil-gas casing structure is installed easier, thereby can realize GIS equipment and transformer independently carries out respectively the tests such as on-the-spot industrial frequency withstand voltage.
Accompanying drawing explanation
