Description

Technical Field

[0001] The present invention relates to the technical field of dehumidification of electric power equipment, and in particular to a dehumidification control method, module and system based on an air curtain machine. Background Art

[0002] Outdoor power cabinets are often located in green belts, where rain and humidity can cause condensation. This can affect insulation and reduce the insulation strength of electrical equipment. Moisture in the air adheres to the surface of the insulation material, lowering the insulation resistance and significantly increasing leakage current. This can easily cause insulation breakdown, creepage, or flashover, leading to electrical failures and power production accidents.

[0003] Current protection against condensation involves draining the generated condensation or using a mechanical drainage structure or physical moisture absorption method at the cabinet opening to absorb and discharge the condensation. However, there is no way to predict and remove condensation in the power cabinet based on the condensation formation mechanism, thereby ensuring the safety of the power cabinet's working conditions. Summary of the Invention

Based on preset judgment criteria, it performs a comprehensive analysis of environmental parameters within each parameter threshold range. It then controls the air curtain's different operating modes to prevent condensation from forming within the power cabinet. If condensation has already formed, it is quickly removed. By integrating various parameters to determine the formation of condensation, the present invention improves the power cabinet control system's ability to predict and detect the formation of condensation, enhancing its ability to prevent and remove condensation.
