Technical Field
[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet with moisture-proof function. Background Art
[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet, which is the final equipment of the power distribution system. In actual use, excessive humidity in the distribution cabinet will cause the electrical equipment to get damp, which will lead to problems such as short circuit and leakage. This may lead to equipment failure or even fire risk. Therefore, it is necessary to maintain a dry environment to prevent moisture from penetrating into the distribution cabinet to ensure the normal operation of electrical equipment.
[0003] After searching, the Chinese patent with publication number CN215732724U discloses a power distribution cabinet with moisture-proof function, including a cabinet, and a protective box is fixedly installed in the middle of both sides of the cabinet. In this power distribution cabinet with moisture-proof function, the fan is working, and the humid air inside the cabinet can be extracted through the exhaust pipe. The humid air will enter the inside of the heatless regeneration adsorption dryer through the exhaust pipe. The heatless regeneration adsorption dryer works to dry the humid air sucked into the inside, so as to remove the moisture contained in the humid air. After the air is dried, it will enter the inside of the air inlet pipe through the extraction of the fan, and then the air will enter the bottom of the cabinet through the air inlet pipe, so as to dry the bottom of the cabinet, and at the same time, the humid air at the bottom of the cabinet can be lifted up to the outside of the cabinet, so as to avoid the situation that the humid air will cause a short circuit to the electronic components.
