Description

Technical Field

[0001] The utility model relates to the technical field of power supply cabinets, in particular to a power supply cabinet with good protection. Background Art

[0002] A power cabinet is a device used to store power equipment and protect it from external influences. Sometimes it is necessary to set up a power cabinet outdoors. In order to prevent rain, some power cabinets are sealed, but the heat dissipation is poor. When the weather is good and the temperature is high, the internal temperature is too high, which can easily affect the normal operation of electrical equipment. If ventilation holes are opened on the power cabinet, although it can have a certain heat dissipation effect, humid air and even rainwater can easily enter the power cabinet through the ventilation holes in rainy weather, and long-term moisture can easily damage the electrical equipment in the power cabinet. Therefore, it is urgent to design a power cabinet that can have both good heat dissipation and waterproof properties when used outdoors. Utility Model Content

[0008] In one embodiment, the upper end of the baffle is hinged to the upper end of the vent, and its rotation axis is along the horizontal direction. A sealing ring is provided on the baffle.

[0009] The adoption of the above technical solution can improve the moisture-proof effect on rainy days.

[0010] In one embodiment, a circle of sealing strip is provided on the cabinet door of the power cabinet body.

[0011] The adoption of the above technical solution can further improve the moisture-proof effect.

[0012] In one embodiment, a storage box is further included. The storage box is a box body with an open upper end, which is used to place a desiccant and is arranged in the power supply cabinet body.

[0013] By adopting the above technical solution, the air in the power cabinet can be dried.
