Dehumidification device for power box cabinet

The invention discloses a dehumidification device for a power box cabinet. The structure of the dehumidification device comprises dehumidification holes, indication lamps, a cabinet body, a fixed plate, hanging lugs, an upper top plate, a box cabinet door, a door handle, cooling holes and a dehumidification mechanism. The two dehumidification holes are arranged, a first dehumidification device anda second dehumidification device are correspondingly arranged at the two dehumidification holes, humidity in the power box cabinet can be effectively sucked to the dehumidification mechanism when thetwo dehumidification devices simultaneously work, moisture of the sucked humid air is absorbed to a sponge block by an absorption effect of the sponge block, and dried air absorbed by the sponge block is sent out through an air outlet passage by a draught fan. Dual dehumidification and dried air discharging are employed, a high-efficiency dehumidification effect is achieved, meanwhile, the humidity in the power box cabine
