technical field

The utility model relates to the technical field of power distribution, in particular to a novel power distribution cabinet.

Background technique

There are many large electrical components installed in the power distribution cabinet. When it is working, a large current flows inside, and the flow of strong current will generate a lot of heat. Especially when it is running for a long time, the temperature inside the power distribution cabinet will suddenly increase. And because the power distribution cabinets are all sealed, dust and foreign matter are reduced from entering the power distribution cabinet, which will make it difficult to discharge the heat generated in the low-voltage power distribution cabinet. Nowadays, the commonly used heat dissipation method is to open grid openings on the cabinet wall and use the space in the cabinet to automatically discharge heat, but this method has poor heat dissipation effect. If the heat cannot be discharged in time and effectively, it will affect the power distribution cabinet. The normal use of electrical components can lead to serious problems such as circuit burnout.
