[0028] A connection box 16 is installed in the cabinet 1, and the two groups of fourth exhaust holes 1212 are connected to the connection box 16. Heaters 17 are installed in the connection box 16 and the guide box 10 for air heating. A first exhaust fan 18 is fixedly installed in the first support tube 6.

[0029] Reference Figure 1 , Figure 2 , Figure 7 and Fig.13At least two groups of DC holes 19 are provided on each baffle frame 2. The through hole 14 is connected to the interior of the electrical area 3 through the DC holes 19. A second row fan 20 is fixedly installed in the DC hole 19. The blowing directions of the two second row fans 20 on the same baffle frame 2 are opposite, and the blowing directions of the two groups of second row fans 20 on the two baffle frames 2 with collinear axes are the same.

[0030] The dehumidification control system also includes two groups of temperature and humidity sensors, one group of temperature and humidity sensors is installed on the outside of the cabinet 1, for detecting the temperature and humidity of the external environment of the cabinet 1, and the other group of temperature and humidity sensors is installed in the electrical area 3, for detecting the temperature and humidity in the electrical area 3.

[0031] Working principle: The temperature and humidity sensor detects the external and internal temperature and humidity of the cabinet 1. Figure 2 The drive assembly 12 in the cabinet is divided into a left side and a right side. When the humidity in the electrical area 3 is higher than the corresponding set threshold value, the humidity outside the cabinet is lower than the corresponding set threshold value, and the air outside the cabinet is in a relatively cold and dry state, the dehumidification control system enters the mode 1 state, and the output shaft of the motor 121 drives the second gear 128 to rotate, and drives the two sets of first gears 123, the support shaft 122, the control board 124 and the arc plate 125 to rotate through the meshing transmission. At this time, the air inlet side and the air outlet side of the through hole 14 of the fixed pipe 13 are both in an open state, and the first The exhaust hole 9, the second air inlet hole 41 and the fourth exhaust hole 1212 are in a blocked state, and the two coaxial second exhaust fans 20 are working. At this time, the second exhaust fans 20 blow air in any direction, left or right, and dry cold air enters the electrical area 3 from the ventilation holes 23 through the through holes 14 and the DC holes 19 on one side. The heat and humid air in the electrical area 3 are blown out from the DC holes 19 and the through holes 14 on the other side through the ventilation holes 23 driven by the low-temperature dry flowing air, thereby achieving cooling and dehumidification in the electrical area 3.

[0032] The temperature and humidity sensor detects the humidity of the electrical zone 3. When the humidity drops to the first threshold, mode two is turned on. The output shaft of the motor 121 on the left side rotates through the transmission control arc plate 125 and the connecting pipe 1210. At this time, the air outlet side of the through hole 14 is blocked by the arc plate 125, and the air inlet side of the through hole 14 is still open. The third air exhaust hole 1211 of the connecting pipe 1210, the first air exhaust hole 9 and the guide box 10 are connected, and the second air inlet hole 41 is still in a blocked state. The first exhaust fan 18 on the left and the second exhaust fan 20 blowing air to the right are working; the motor 121 on the right side controls the air inlet side and the air outlet side of the through hole 14 of the fixed tube 13 through the transmission. In the open state, the corresponding first exhaust hole 9, second air inlet hole 41 and fourth exhaust hole 1212 are in a blocked state, and the external cold air flows from the ventilation hole 23 through the first air inlet hole 126, the second air inlet hole 41, the junction box 4 and the first support pipe 6 into the drying cylinder 83 for drying. The dried gas enters the electrical area 3 through the second support pipe 7, the first exhaust hole 9, the third exhaust hole 1211, the guide box 10 and the second exhaust hole 11. The working heat and moisture of the electrical components in the electrical area 3 are blown out from the right direct current hole 19, the through hole 14 and the ventilation hole 23 driven by the cold air, thereby circulating the heat and the humid air in the electrical area 3 to achieve the dehumidification effect. It should be noted that when in the mode 1 dehumidification state, the humidity in the electrical area 3 decreases at a faster rate, and can also be directly dehumidified through mode 1 until it drops to the set threshold. The rate can be detected by setting the rate threshold of the humidity. Similarly, the dehumidification control system can also be in the mode 2 dehumidification state until the humidity drops to the set threshold.

[0033] As dehumidification proceeds, when the humidity and temperature in the electrical area 3 drop to the set second threshold, the second threshold is higher than the set threshold, the dehumidification control system enters mode three, and the heater 17 in the left guide box 10 starts to heat the air. The heat is brought into the electrical area 3 by the flowing wind, thereby further performing the dehumidification operation, improving the dehumidification while avoiding condensation problems in the electrical area 3.

[0034] When the humidity in the electrical area 3 and outside the cabinet is high, the dehumidification control system directly enters mode 2 for dehumidification to avoid introducing moisture outside the cabinet into the cabinet. After the humidity and temperature in the electrical area 3 drop to the set second threshold, it enters mode 3 for dehumidification.

[0035] In the dehumidification control system of the present invention, when the desiccant in the drying cylinder 83 on one side has worked for a period of time, the drying cylinder 83 on the other side is switched to work, and the drying mode is switched to dry regeneration of the desiccant. For example, for regeneration of the desiccant on the left side, the output shafts of the two sets of motors 121 continue to rotate after entering mode 2 through the transmission control dehumidification control system, the air outlet side of the through hole 14 is still in a closed state, the first air inlet 126 and the second air inlet 41 are still in a connected state, and the connecting pipe 1210 rotates to block the first air outlet 9 again. At this time, the first air outlet 9 is not connected to the third air outlet 1211, and the third air inlet 41 is not connected to the third air outlet 1211. The air hole 71 is connected to the fourth exhaust hole 1212, the first exhaust fan 18 on the right side is working, and the external air is dried by the desiccant on the right side and then enters the connection box 16 from the third air inlet hole 71 and the fourth exhaust hole 1212. The heater 17 in the connection box 16 is working, and the dry air drives the heat from the fourth exhaust hole 1212 on the left side through the third air inlet hole 71 and the second support tube 7 to enter the dry cylinder 83 on the left side to regenerate the wet desiccant, and the exhausted hot and humid air is discharged from the bottom of the dry cylinder 83 through the first support tube 6, the junction box 4, the air inlet side of the through hole 14 and the ventilation hole 23 to the outside of the cabinet, thereby realizing the drying process. It should be noted that the wet desiccant can also be maintained by replacing the dry cylinder 83.

[0036] When the humidity and temperature in the electrical area 3 are lower than the set threshold, and the moisture outside the cabinet 1 is higher than the set threshold, the motor 121 drives the arc plate 125 to block the air inlet side of the through hole 14, so that the cabinet 1 enters a relatively sealed state, reducing the risk of moisture outside the cabinet entering the cabinet.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
