[0032] When in use, the first humidity sensor 18 and the first temperature sensor 17 are arranged so as to monitor the temperature and humidity inside the cabinet 1 .

[0033] When the embodiment of the present application is in use, firstly, the second humidity sensor 11 and the first humidity sensor 18 are respectively arranged on the left and right sides of the cabinet 1, and a plurality of cooling fans 16 are arranged at the front end of the lower part of the top cover 13. The top cover 13 protrudes a certain length from the front of the cabinet 1. The lower plate of the top cover 13 is provided with mounting holes for the cooling fans 16 and fixing holes corresponding to the fastening screws 21. A fastening nut 15 is welded on the inner side of the fixing hole to ensure that the cooling fans 16 are firmly fixed.

The second temperature sensor 12 and the first temperature sensor 17 detect the temperature in the cabinet 1 in real time. When it is detected that the temperature in the cabinet 1 reaches the set temperature value, the cooling fan 16 is started to extract the hot air in the cabinet 1, and the air enters the cabinet 1 from the air inlet louver 2, so that the air in the cabinet 1 circulates and the hot air is continuously extracted. The cooling fan 16 is multi-speed controlled. According to the real-time detection of the second temperature sensor 12 and the first temperature sensor 17, when the operation of the previous gear cannot lower the temperature in the cabinet 1, the cooling fan 16 is started. 16 is controlled and adjusted by the PLC system to ensure that the heat of the electrical components 14 in the cabinet 1 is discharged to the outside of the cabinet 1 in time. When the electric control cabinet is in a relatively humid environment, the second humidity sensor 11 and the first humidity sensor 18 detect that the humidity of the air entering the cabinet 1 is too high, which will affect the normal operation of the electrical components 14. The second dehumidifier 10 and the first dehumidifier 19 are started to dehumidify the air coming in from the air inlet. The second dehumidifier 10 and the first dehumidifier 19 are also multi-speed controlled. According to the different humidity in the air, the dehumidification is controlled and adjusted by the PLC system to ensure that the humidity of the air entering the cabinet 1 meets the normal operation of the electrical components 14. The cooling fan 16, the second dehumidifier 10 and the first dehumidifier 19 are controlled and adjusted by the PLC system.While meeting the operating environment requirements of the electrical components 14, the purpose of energy saving is achieved.
