Low-voltage distribution cabinet

Abstract

The invention discloses a low-voltage power distribution cabinet which comprises one or more power distribution rods, the one or more power distribution rods are encircled into a circle at intervals,and a circular air guide channel is formed in the middle of the power distribution poles; supports are arranged in the air guide channel in the length direction of the air guide channel, bases are arranged at the bottoms of the supports and fixed to the ground through screws, rotating shaft sleeves are rotationally arranged in the middles of the supports in a sleeving mode, and a connecting rod iswelded and fixed to the position, directly facing each power distribution rod, of the outer wall face of each rotating shaft sleeve. According to the invention, the installation form of a traditionalpower distribution cabinet is completely changed, compared with the prior art, a distributed independent rod-shaped structure is adopted, and all power distribution modules are reasonably dispersed and independently assembled, so that the low-voltage power distribution cabinet not only has very good fireproof safety, but also has very good thermal dissipation performance, is particularly suitablefor outdoor, maintenance can be independently treated, cannot expose other power distribution modules, and has very good impact resistance and wind resistance.

Description

technical field [0001] The invention relates to the field of power distribution, in particular to a low-voltage power distribution cabinet. Background technique [0002] In the prior art, various types of power distribution cabinets are commonly used for power distribution, and the power distribution cabinets are installed in many different occasions, and indoor and outdoor power distribution cabinets are common. However, outdoor power distribution cabinets require a higher installation environment. After outdoor installation, there are many risks. In windy weather, the impact of airflow is relatively large. If cooling holes are installed, a large amount of airflow and dust will be poured into the interior; in addition, since the traditional power distribution cabinet is an integrated cabinet installation structure, each distribution cabinet The heat transfer between the electric modules is relatively obvious, and the heat is concentrated, which leads to the overall high in...

Problems solved by technology

However, outdoor power distribution cabinets require a higher installation environment. After outdoor installation, there are many risks. In windy weather, the impact of airflow is relatively large. If cooling holes are installed, a large amount of airflow and dust will be poured into the interior; in addition, since the traditional power distribution cabinet is an integrated cabinet installation structure, each distribution cabinet The heat transfer between the electric modules is relatively obvious, and the heat is concentrated, which leads to the overall high internal temperature and low heat dissipation efficiency. At the same time, since each power distribution module is installed in a space, once it is overheated and caught fire, the entire distribution box will burn. , the fire spread rapidly, which brought a lot of inconvenience to the rescue
