Low voltage distribution cabinet

Abstract

The invention discloses a low-voltage power distribution cabinet, which comprises more than one distribution rod, and more than one distribution rod is spaced to form a circle and forms a circular air guide channel in the middle, and the inner edge of the air guide channel is The brackets arranged in the length direction of the air guide channel are provided with a base at the bottom of the brackets, and the bases are fixed on the ground by screws. The middle of the brackets is rotated and fitted with a rotating sleeve, and the outer wall of the rotating sleeve is facing each fitting. The poles are all welded to fix a connecting rod. The present invention completely changes the installation form of the traditional power distribution cabinet, and uses a decentralized independent rod-shaped structure, and disperses and assembles each power distribution module group separately, which not only has very good fire safety, but also has good heat dissipation performance , especially suitable for outdoor use, maintenance can be handled separately, without exposing 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
