Description

Technical Field

[0001] The utility model relates to an inflatable cabinet. Background Art

[0002] The gas cabinet is a high-voltage switchgear for power distribution systems. It is widely used in medium-voltage (3.6kV to 40.5kV) power systems to control, protect and isolate power equipment. The main feature of the gas cabinet is the use of gas insulation technology, usually using sulfur hexafluoride (SF6) gas as an insulating and arc-extinguishing medium. The existing gas cabinet includes a bottom beam and a side plate. In the actual transportation process, it was found that the existing gas cabinet was not firmly connected during the lifting process due to the thin connection between the bottom beam and the side plate of the gas cabinet. Under the external force or vibration during lifting, the mechanical strength of the connection is insufficient and loose, and severe deformation or damage occurs. Improvements and optimizations are made to this end. Utility Model Content
