Background

In the field of high-voltage equipment, SF6 gas is generally filled as an insulating gas in a gas chamber of equipment such as a circuit breaker. When the high-pressure equipment is expanded, the first-stage equipment and the second-stage equipment need to be butted to complete the connection of the air chambers.

The existing connection structure, as shown in fig. 1, is composed of a mounting flange 2 installed at the port of the air chamber, a transition short pipe 6 and a cover plate 7, when assembling, the two ends of the transition short pipe 6 are connected with the mounting flange 2 and the cover plate 7 in a sealing manner, an inflation hole 71 is formed on the cover plate 7, an adsorption cylinder 8 for placing an adsorbent a is arranged on the inner side of the cover plate 7, and the inflation hole 71 is connected with an inflation meter 9. The above structure has disadvantages in that: because the sizes of the air chamber ports of the high-voltage equipment are different, in order to ensure that the transition short pipe 6 and the cover plate 7 can be matched with the air chamber ports, a special accessory manufacturer needs to be found for customization, a set of die matched with the sizes of the ports is needed, and the high-voltage equipment manufacturer has large limitation on the operation of purchasing accessories and high cost.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an end cover plate for GIS adopts the standard component to assemble, simplifies overall structure, reduce cost.

In order to achieve the above purpose, the solution of the present invention is:

an end cover plate for a GIS comprises a standard end socket, a mounting flange, a charging connector and an adsorbent placing part; the standard end socket is connected to the opening of the mounting flange in a sealing manner, and the top end of the standard end socket is provided with a through hole; the inflating nozzle is connected to the outer side of the standard end socket and is arranged opposite to the through hole; the adsorbent placing part is connected to the inner side of the standard end socket and used for placing the adsorbent.

The adsorbent placing part comprises a horizontal plate and a vertical plate connected to the horizontal plate; the vertical plate is upwards connected to the top of the inner side of the standard seal head and used for hanging the transverse plate, and the transverse plate is used for placing an adsorbent.

The vertical plate is connected with the transverse plate and the standard end socket through welding.

And sealing structures are arranged on the inner side and the outer side of the joint of the standard end socket and the mounting flange.

After the technical scheme is adopted, the transition short pipe and the cover plate in the traditional structure are replaced by the standard end socket, the standard end socket is used as an industrial standard part, the size and the specification of the standard end socket are uniform in production, special customization is not needed, and the cost can be obviously reduced; simultaneously, compare in traditional structure, the utility model discloses a structure is simplified, the equipment is easier.
