The door panel 1, the insulating shell 5, the insulating busbar tube 12, the insulating bracket 13 and the insulating middle partition 14 are all formed by coating the outer side of the material with insulating material. The insulating material is polytetrafluoroethylene, so as to achieve insulation and anti-electric shock of the switch cabinet. The electrical components are respectively installed on the insulating middle partition 14. After the electrical components are installed, the connecting wires to be connected to the electrical components are respectively passed through the insulating busbar tubes 12 corresponding to the insulating middle partition 14, so that the insulating busbar tubes 12 cover the connecting wires of the electrical components to protect the connecting wires. At the same time, the connecting wires can be neatly arranged to avoid entanglement between the connecting wires, thereby improving the service life of the connecting wires.

[0023] In the present invention, the drying assembly includes a lower exhaust fan 11 and an upper exhaust fan 15, which are both fixed to one side of the rectangular frame by bolts. A dehumidification box 10 is fixed to one side of the air inlet of the lower exhaust fan 11 and the upper exhaust fan 15 by bolts. The top and bottom of the dehumidification box 10 are provided with a plurality of wind slots 16. Two replacement boxes 18 for placing desiccant bags are slidably connected to the dehumidification box 10. The bottom of the replacement box 18 is provided with a plurality of through holes. A T-shaped handle 17 is fixed to the outer wall of one side of the replacement box 18 by bolts. When the lower exhaust fan 11 and the upper exhaust fan 15 are started, the dehumidification box 10 is opened. The fan 11 and the upper exhaust fan 15, the lower exhaust fan 11 and the upper exhaust fan 15 will extract the air in the insulating housing 5. The air extracted by the lower exhaust fan 11 and the upper exhaust fan 15 will enter the dehumidification box 10 through the air duct 16. At this time, the desiccant bag in the replacement box 18 will absorb moisture in the air, thereby drying the air. After the drying is completed, the air will be discharged from the dehumidification box 10 through the air duct 16, thereby ensuring that the insulating housing 5 is in a dry state, preventing the humid air from corroding the connecting wires, and further improving the service life of the connecting wires;

The rotating stopper 20 is located at the junction of the two replacement boxes 18 to resist the two replacement boxes 18. An embedding groove is provided on one outer wall of each side of the two replacement boxes 18, and a magnetic block 19 is embedded in the embedding groove, and the magnetic block 19 is fixed to the rotating stopper 20. When the desiccant bag has been used for a long time, the rotating stopper 20 is rotated to disengage the rotating stopper 20 from the magnetic block 19 and no longer resist the replacement box 18. At this time, the replacement box 18 can be pulled to the outside of the dehumidification box 10 by the T-shaped handle 17, so that the desiccant bag in the replacement box 18 can be replaced. The outer wall of the insulating shell 5 on the side away from the door panel 1 is fixed with a thickened plate 9 by bolts. The thickened plate 9 can strengthen the strength of the back plate of the insulating shell 5.

One side of the epoxy resin insulating baffle 6 is provided with multiple observation slots 4 corresponding to the insulating middle partition 14, and the insulating middle partition 14 passes through the observation slot 4. A supporting angle plate 3 is fixed by bolts on one side of the door panel 1. A guide groove is provided on the top of the supporting angle plate 3. A support arm 2 that moves along the groove direction of the guide groove is provided in the guide groove, and the support arm 2 is rotatably connected to the insulating shell 5. In the process of rotating and opening the door panel 1, the support arm 2 and the insulating shell 5 will rotate and the support arm 2 will move in the guide groove, thereby limiting the opening range of the door panel 1. The bottom outer wall of the insulating shell 5 is located at the four corners and is fixed with support feet 7 by bolts.

[0025] The working principle of the present invention is as follows: when in use, the electrical components are respectively installed on the insulating middle partition 14. After the installation of the electrical components is completed, the connecting wires that need to be connected to the electrical components are respectively passed through the insulating busbar tubes 12 corresponding to the insulating middle partition 14, so that the insulating busbar tubes 12 cover the connecting wires of the electrical components to protect the connecting wires. At the same time, the connecting wires can be neatly arranged to avoid entanglement between the connecting wires, thereby improving the service life of the connecting wires. At the same time, the lower exhaust fan 11 and the upper exhaust fan 15 are started. The lower exhaust fan 11 and the upper exhaust fan 15 will extract the air in the insulating shell 5. The air extracted by the lower exhaust fan 11 and the upper exhaust fan 15 will enter the dehumidification box 10 through the wind groove 16. At this time, the desiccant bag in the replacement box 18 will absorb moisture in the air, thereby drying the air. After drying, the air will be discharged from the dehumidification box 10 through the wind groove 16, thereby ensuring that the inside of the insulating shell 5 is in a dry state, avoiding humid air from corroding the connecting wires, and further improving the service life of the connecting wires.
