Description

Technical Field

[0001] The utility model belongs to the field of switch cabinet dehumidification, and more specifically, particularly relates to an intelligent dehumidification device for a switch cabinet. Background Art

[0002] The switch cabinet is an electrical equipment. The external line of the switch cabinet first enters the main control switch inside the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. Some also have high-voltage and low-voltage switch cabinets, with high-voltage busbars, such as power plants, etc. Some are also equipped with low-frequency load shedding to protect the main equipment. In humid climatic conditions, the switch cabinet is easy to absorb moisture, which aggravates the increase of internal moisture. At the same time, the switch cabinet will generate heat during operation. If the heat dissipation capacity of the equipment is insufficient, it will cause moisture to condense inside the switch cabinet, increasing the risk of moisture accumulation.

[0003] Based on the above, the inventors have discovered the following problems: when some existing dehumidification devices absorb moisture, when the moisture in the adsorption material is in a saturated state, they cannot continue to absorb moisture. If the staff cannot replace it in time, a large amount of moisture will accumulate in the switch cabinet, increasing hidden dangers.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and an intelligent dehumidification device for a switch cabinet is provided, in order to achieve a more practical purpose. Utility Model Content
