In this embodiment, a high-voltage switch cabinet includes a cabinet body 1, and an installation cavity 13 is opened in the cabinet body 1. A baffle plate 6 is fixedly installed in the installation cavity 13, and a ventilation cavity 7 is formed between the outer wall of the baffle plate 6 and the inner wall of the installation cavity 13. A plurality of air inlets 3 are opened at the top of the left and right sides of the cabinet body 1, and the air inlets 3 are communicated with the ventilation cavity 7. A blowing device 8 is fixedly installed at the bottom of the baffle plate 6. An exhaust port 11 is opened at the top of the outer wall of the cabinet body 1, and the exhaust port 11 is communicated with the installation cavity 13. In the design of this structure, the blowing device 8 is installed at the bottom and the air inlet 3 is installed at the top, forming a staggered form, which effectively prevents dust and other impurities from directly entering the high-voltage switch cabinet. At the same time, an exhaust port 11 is opened at the top of the high-voltage switch cabinet. Since the heat is upward, the blowing device 8 at the bottom is cooperated with the blowing device 8 to blow the heat out from the exhaust port 11 from bottom to top, so that the high-voltage switch cabinet has the effect of rapid heat dissipation.

[0026] In this embodiment, a baffle 4 is fixedly installed at the exhaust port 11 on the top of the cabinet 1. The baffle 4 can prevent dust and other impurities in the air from directly being attached to the dustproof net 12, thereby reducing the service life of the dustproof net 12. In addition, a dustproof net 12 is fixedly installed at the exhaust port 11, which effectively prevents dust and other impurities in the air from entering the installation cavity 13 from the exhaust port 11.

[0027] In this embodiment, the blowing device 8 includes a protective cover 81 and an air inlet fan 83. The protective cover 81 is fixedly connected to the bottom surface of the baffle plate 6 by bolts. The setting of the protective cover 81 plays a role in protecting the air inlet fan 83. A connecting cavity 82 is opened in the protective cover 81, and the connecting cavity 82 is communicated with the ventilation cavity 7. The air inlet fan 83 is fixedly installed on the inner wall of the connecting cavity 82. The setting of this structure realizes the function of exchanging air with the outside in the installation cavity 13 through the connection cavity 82 and the communication with the ventilation cavity 7. In addition, the air inlet fan 83 is provided to accelerate the heat dissipation of the installation cavity 13 and prevent the possibility of heat accumulation.

[0028] In this embodiment, an air outlet 84 is provided on the outer wall of the protective cover 81 at a position opposite to the air inlet fan 83 . This structural arrangement allows the air blown by the air inlet fan 83 to be directly blown into the installation cavity 13 .

[0029] In this embodiment, a filter 31 is fixedly installed at the air inlet 3 . This structural arrangement effectively prevents dust and other impurities in the air from entering through the air inlet 3 .

[0030] In this embodiment, a door body 2 is fixedly connected to the front end of the cabinet body 1 via a hinge, and a temperature controller 5 is fixedly installed on one side of the door body 2. This structure plays a control role.

[0031] In this embodiment, a temperature monitor 14 is fixedly installed on the top of the inner wall of the cabinet 1 and located on one side of the exhaust port 11 . This structural design can effectively monitor the temperature inside the installation cavity 13 .

[0032] In this embodiment, the temperature monitor 14 is electrically connected to the temperature controller 5 and the air inlet fan 83, so that the temperature in the installation cavity 13 can be detected in real time by the temperature monitor 14 and transmitted to the temperature controller 5. Since the temperature controller 5 is programmed, the rotation speed of the air inlet fan 83 is automatically controlled according to different temperature conditions.
