Description

technical field

[0001] The invention relates to an automatic control device for humidity in a cabinet. Background technique

[0002] Within the scope of the power system, SM6 series switch cabinets have been continuously promoted and applied, and have become the main equipment used for 10kV switching, and are responsible for the power supply of the main urban area. However, judging from the situation in recent years, the switchgear located in the basement or low-lying place is relatively humid due to its geographical location, which makes the humidity in the switchgear relatively high, and the main indoor dehumidification equipment (indoor moisture absorber and SM6 ring network cabinet) The attached heaters) are manually controlled, unable to dehumidify in time, causing condensation, water film and other phenomena on the surface of various equipment in the cabinet, and flickering, creepage or discharge on the surface of some equipment, which affects the insulation level of t...
