The smart dehumidification device changes the passive dew prevention method to an active dew guidance method, effectively preventing equipment aging, insulation strength reduction, secondary terminal breakdown, material mold growth, and rusting of steel structures within the. The smart dehumidification device changes the passive dew prevention method to an active dew guidance method, effectively preventing equipment aging, insulation strength reduction, secondary terminal breakdown, material mold growth, and rusting of steel structures within the. The utility model discloses an intelligent power distribution cabinet dehumidifying device for an electric power system, comprising: the intelligent power distribution cabinet comprises a dehumidification casing, an intelligent power distribution cabinet body and a humidity sensor, wherein the rear. The smart dehumidification device uses semiconductor refrigeration to actively draw humid air from a sealed space into the dehumidification duct under the action of a fan. The moisture in the air condenses into water after passing through the semiconductor refrigeration unit, and is then discharged. In operating power transmission and transformation equipment, such as switchgear cabinets, pad-mounted transformers, control cubicles, ring main units (RMUs), and outdoor terminal boxes, the compact insulation distances between components make them highly susceptible to electrical discharge. As for dehumidification solutions, you can choose an enclosure heater or electrical cabinet dehumidifier for power distribution. Today, this article will introduce the two dehumidification solutions from reason, their comparison, and so on. Working power supply: AC/DC85-265V, power 20W. Direct-sale by China Manufacturer. The humid air is sucked into the dehumidification duct under the action of a fan. Aiming at the deficiencies of the prior art, the present invention provides an intelligent power distribution cabinet dehumidification system and dehumidification method for power systems, which solves the problem of poor effect and long dehumidification time when dehumidification is.
