[0001] The utility model relates to the technical field of electric power equipment, in particular to a moisture-proof power distribution cabinet. Background Art

[0002] With the development of modern industrial and civil power facilities, distribution cabinets, as an important part of the power system, their performance stability and safety are crucial to the reliable operation of the entire power system. Especially in humid environments, the internal components of the distribution cabinets are easily corroded by moisture, resulting in electrical performance degradation, insulation failure, and even serious accidents such as short circuits and fires. The distribution cabinets need to be dehumidified to ensure the normal operation of the electrical components inside the distribution cabinets.

[0003] However, in the existing distribution cabinet technology, moisture-proof measures mainly rely on the circulation and exchange of air inside the cabinet with the outside air. However, in a humid environment, the outside air is still in a humid state, which will bring moisture in the outside air into the distribution cabinet, reducing the moisture-proof effect of the distribution cabinet. For this reason, the applicant proposes a moisture-proof distribution cabinet to solve the above problem. Utility Model Content

[0004] The purpose of the present invention is to provide a moisture-proof power distribution cabinet to solve the problems raised in the above background technology.
