The intelligent distribution cabinet dehumidification system for a power system according to claim 5, characterized in that: The output ends of the temperature sensor (32) and the humidity sensor (33) are both connected to the input end of the information conversion unit (342), and the output end of the information conversion unit (342) is respectively connected to the input ends of the control unit (341) and the wireless transceiver unit (343).

7. The dehumidification method for the intelligent distribution cabinet dehumidification system of the power system according to claim 5, characterized in that: The specific steps include: Step 1: water is poured into the water storage tank (1) through the water inlet pipe, and then the fan (9) is started by controlling the single chip microcomputer (345). The fan (9) draws air along the third connecting pipe (17), draws air into the filter cover (15), filters dust in the air through the dust filter (16), and then filters water vapor through the filter plate (13). At this time, the filtered water vapor flows to the fixed block (14) below, and then is discharged along the drainage groove (26). At this time, the air filtered of dust and water is transported to the fan (9) ), transported to the air collecting chamber (11) through the first connecting pipe (10), and then exchanged heat with the water in the water storage tank (1) through the heat conduction of the first heat sink (27) and the second heat sink (29), converted into cold air, and then transported to the filter chamber (20) along the air outlet pipe (5), and after the last moisture is adsorbed by the activated carbon plate (21), it is transported to the first blowing pipe (18) and the second blowing pipe (19), and blown out along the air outlet hole (25), blowing out the moisture in the power distribution cabinet (2) along the ventilation filter (3); Step 2: When replacing the activated carbon plate (21), the activated carbon plate (21) is taken out for replacement, and then the fixing bolts (24) are tightened to drive the fixing plate (23) to squeeze the sealing gasket (22), so that the fixing plate (23) and the filter chamber (20) expand, thereby sealing the gap between the activated carbon plate (21) and the filter chamber (20); Step 3: When in use, the humidity is detected by the temperature sensor (32) and the humidity sensor (33), the fan (9) and the first solenoid valve (6) are controlled to open and close by the single chip microcomputer (345), and the second solenoid valve (31) is controlled to open, so that the wind is blown out along the dispersion pipe (30) to clean the dust filter (16).
