The placement cylinder 71 is placed vertically to better place the dryer 78. At the same time, the shell of the dryer 78 is protected to prevent the dryer 78 from being damaged. The cover plate 72 is connected to the placement cylinder. On the top of 71, a cover plate 72 is provided to seal the placement cylinder 71 to prevent external dust from entering and damaging the internal equipment, and to ensure that the internal dryer 78 is clean. A block 73 is installed in the middle of the outer surface of the placement cylinder 71, and the inner side of the block 73 is in contact with the outer side of the placement cylinder 71 and fixed. The block 73 is provided to fix the placement cylinder 71 to prevent the placement cylinder 71 from shaking during operation, thereby affecting the operation of the internal dryer 78.

[0024] Specific implementation process: When the dehumidification device of the high-voltage switch cabinet needs to be used, first place it to the position where it needs to be used, and the position must be horizontal. Then the user can use it in the place related to the dehumidification device. First, put the equipment inside the switch cabinet 1 into the switch cabinet 1. Then, before using the equipment, the user must first check whether the cabinet door 2 is closed. If not, the cabinet door 2 must be closed and tightly closed with the handle 3 for subsequent use of the equipment. Then, the equipment is moved to the required operation place through the pulley 4. First, use the dehumidification device 6 to dehumidify the inside of the switch cabinet 1. The user first uses the external power supply 61 to start, and provides power to the dehumidifier 63 through the wire 62 to start the dehumidifier 63. Then, the dehumidifier 63 dehumidifies the moisture inside the switch cabinet 1 through the filter 5. After working for a period of time, the dehumidification plate on the dehumidifier 63 will produce water, which will fall into the water tank 65 along the dehumidification plate. The user waits until the water in the water tank 65 accumulates to a certain extent, and then uses the gripper 66 to install it on the right side of the switch cabinet 1. The water tank 65 in the side bottom groove is taken out, and the water will pour out through the leaking groove 67, so that the dehumidification effect is achieved. However, the dehumidification effect of the dehumidification device 6 may not be enough, and the drying device 7 needs to be used for auxiliary drying. First, the user needs to fix the placement tube 71 on the filter 5 on the left side of the switch cabinet 1 through the block 73, and then the user needs to place the dryer 78 into the placement tube 71, and then cover the cover 72 to seal it. Then the user needs to start the heater 76 of the electric box 75, and then heat the dryer 78 through the external connection 74 to make the dryer 78 heat up, and then the user needs to turn on the exhaust fan 77 to further dry the remaining undehumidified moisture in the internal environment of the switch cabinet 1. The moisture will be absorbed by the absorbent cotton 79 through the exhaust fan 77, absorbed into the placement tube 71, and then dried and evaporated by the dryer 78, so as to achieve the drying function. After using the dehumidification device 6 and the drying device 7, the user needs to clean and maintain them, and disassemble them and place them separately when idle. This is the method of using the device.
