[0026] The dehumidification component 10 includes a fan 101 arranged on one side of the cabinet 1, and a condenser 102 is arranged on the side away from the fan 101. By setting the dehumidification component 10, when the fan 101 is turned on, it will generate suction to extract the air inside the cabinet 1 and make it flow through the condenser 102. The air flowing through exchanges heat with the refrigerant inside the condenser 102. Since the refrigerant is cooled in the condenser 102, its temperature is much lower than the temperature of the extracted air. Therefore, the water vapor in the air will condense on the surface of the condenser 102 when it is cold, forming liquid water. The liquid water will then drip from the surface of the condenser 102, and the humidity in the air will drop rapidly, thereby achieving the purpose of dehumidification; the collection component 11 includes a collection box 1 arranged on the outside of the condenser 102 11. The inner side of the collection box 111 is connected to a connecting pipe 112, and the other end of the connecting pipe 112 is connected to the interior of the storage box 2.

By setting the installation component 14, the mounting seat 141 can limit the connecting block 142, and the connecting block 142 can slide with the dehumidification plate 13 out of the interior of the outer shell 4, thereby improving the convenience of maintenance and replacement of the dehumidification plate 13.

[0027] Working principle: During use, when the control switch 5 needs to be inspected, the motor 61 is started, and the worm 62 drives the worm wheel 63 to rotate. At the same time, the transmission shaft 7 drives one end of the first rotating rod 81 to rotate with it as the center of the circle. The other end of the first rotating rod 81 drives the second rotating rod 82 to move in a parallel direction as the rotation angle changes, so that the control switch 5 slides forward along the slide groove 92 and then reaches the outside of the cabinet 1, which improves the convenience of inspection. When the humidity exceeds the normal range, the humidity sensor 15 will send an instruction to the PLC controller, and then the PLC controller will turn on the fan 101 and generate suction at the same time. The air inside the cabinet 1 is extracted and made to flow through the condenser 102, exchanging heat with the refrigerant inside the condenser 102. Then, the water vapor in the air will condense on the surface of the condenser 102 when it is cold, forming liquid water, which then drips from the surface of the condenser 102. At the same time, the humidity in the air decreases rapidly. The liquid water first falls into the collection box 111, and then flows into the storage box 2 through the connecting pipe 112. The dehumidified air then enters the outer shell 4 through the delivery pipe 12, and after further absorbing moisture through the dehumidification plate 13, it immediately returns to the inside of the cabinet 1, completing the cycle, thereby improving the stability of the operation of the electrical equipment.
