Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a dust-proof power distribution cabinet with a replaceable filter screen. Background Art

[0002] Power cabinets are also called distribution cabinets or distribution boxes. With the development of technology, various types of distribution cabinets have been widely used, so the requirements for supporting facilities of distribution cabinets are also constantly improving.

[0003] However, the current distribution cabinets on the market usually have ventilation and moisture-proof measures with ventilators on both sides. Although the ventilators have a certain ventilation and moisture-proof function, they also have a reverse effect. For example, external dust can easily enter the interior of the distribution cabinet through the ventilators. Therefore, dust screens are often installed in the ventilation areas. However, after a long time, debris will adhere to the dust screens. If they are not cleaned and replaced, the ventilation effect will be affected. The current dust screens are mostly installed and fixed with bolts. Once the bolt heads are rusted, it will be very troublesome to disassemble them. In response to the above problems, the inventors proposed a dust-proof distribution cabinet with a replaceable filter screen to solve the above problems. Utility Model Content
