Technical field

The invention relates to the technical field of distribution cabinets, specifically a municipal distribution cabinet.

Background technique

Power distribution cabinets need to pass wires through and then connect them to the electrical equipment at the outside. There are also electrical components inside the power distribution cabinets, and the internal electrical components also generate heat. Power distribution cabinets installed outdoors are often exposed to wind and sunlight. Therefore, when the sun is strong, the temperature inside the distribution cabinet is relatively high. At the same time, the heat generated by the electrical components makes it difficult to dissipate the temperature inside the distribution cabinet. At present, the temperature inside the distribution cabinet is The heat dissipation function is to directly open a communication port with the interior of the power distribution cabinet. Although this has effective heat dissipation, in the case of harsh annular conditions, external sand and dust can easily be carried to the inside of the power distribution cabinet by the wind;
