Description

Technical Field

[0001] The utility model relates to the technical field of GIS shells, in particular to a GIS shell with an anti-extrusion side groove structure. Background Art

[0002] GIS is the English abbreviation of gas-insulated fully enclosed switchgear. GIS consists of circuit breakers, disconnectors, earthing switches, mutual inductors, lightning arresters, busbars, connectors and outgoing line terminals. These devices or components are all enclosed in a metal grounded casing, which is filled with SF6 insulating gas at a certain pressure. Therefore, it is also called SF6 fully enclosed switchgear. Therefore, the shell used in GIS is particularly important. The GIS shell on the market does not have an anti-extrusion structure and is very easy to be extruded during use, which will cause damage to the internal device and cause trouble for the staff.

[0003] And in the document with publication number CN215452079U, a GIS shell with an anti-extrusion side groove structure is mentioned. The shell is convenient for the first anti-compression ring and the second anti-compression ring to be clamped and installed through the limiting side groove. Under the action of the second anti-compression ring and the first anti-compression ring, it can play a good anti-extrusion ability, and a positioning groove and a positioning block are arranged at the connection between the first anti-compression ring and the second anti-compression ring. Through the clamping action of the positioning groove and the positioning block, it is convenient for the staff to disassemble and assemble. The first protective shell and the second protective shell are conveniently connected and fixed by connecting bolts, which is convenient for the staff to disassemble and assemble. The second protective shell and the first protective shell are made of high-strength It is made of high-strength material and can provide better protection for the electrical body. The connection port facilitates the connection of internal devices, and the movable hinge facilitates the opening and closing of the closed cover, which brings convenience to the staff. A connecting hole is provided on the outside of the sealing port, which facilitates the installation of the sealing cover, and the sealing ring can be snap-fitted and installed by embedding the ring groove. Under the action of the sealing ring, the airtightness of the sealing cover can be better, which greatly improves the practicability of the device. However, there are still certain defects that need to be optimized. The specific defects are as follows: the shell is connected by the snap-fit ​​action of the card slot and the card block, which is easy to fall off when hit by external force and is not stable enough.

[0004] Therefore, it is particularly important to design a GIS shell with an anti-extrusion side groove structure to change the above technical defects and improve the overall practicality. Utility Model Content
