[0002] Combined electrical cabinets have been widely used in power distribution systems. The high-voltage fuses of the gas-filled combined electrical cabinets with fully insulated and fully enclosed technology are placed in the barrel, which is inconvenient to replace. The requirements for the plug-in cable head are high, and the structure is not only complicated. , and the manufacturing cost is high, and the maintenance workload and cost are increased. Although the conventional air-insulated combined electrical cabinet is cheap, it occupies a large area, and the load switch and grounding switch are greatly affected by the environment during operation, and daily maintenance heavy workload

The invention discloses an inflatable combined electric appliance cabinet. According to the inflatable combined electric appliance cabinet, the structure is relatively simple, wiring is convenient, and the maintenance workload is small. The inflatable combined electric appliance cabinet comprises an air box (1), a first wire-out component and a second wire-out component. One end of the electric connection portion of a first air insulation bush (2) is connected into the air box (1) in a sealing mode, and the other end of the electric connection portion of the first air insulation bush (2) is exposed out of the air box (1). One end of a second air insulation bush (3) and one end of a supporting insulator (4) are connected with a case of the air box (1). A high voltage fuse (5) is installed between the other end of the second air insulation bush (3) and the other end of the supporting insulator (4). The supporting insulator (4) is used for supporting the high voltage fuse (5). One end of the electric connection portion of the second air insulation bush (3) is connected into the air box (1) in a sealing mode, and the other end of the electric connection portion of the second air insulation bush (3) is exposed out of the air box (1).
