Introduction to the types of common distribution boxes
The commonly used distribution boxes are made of wood and metal. Because the protection level of metal distribution boxes is higher, metal is used more.
Classification by structural characteristics and use:
(1) Fixed panel switchgear, often called switchboard or power distribution panel. It is an open-type switch cabinet with panel shielding, the front has a protective effect, the back and sides can still touch the live parts, and the protection level is low. It can only be used in industrial and mining enterprises that require low power supply continuity and reliability. The transformer room is used for centralized power supply.
(2) Protective switchgear refers to a low-voltage switchgear with all sides enclosed except the installation surface. The electrical components such as switch, protection and monitoring control of this kind of cabinet are installed in a closed shell made of steel or insulating material, and can be installed on the wall or away from the wall.
(3) Drawer switch cabinet. This kind of switch cabinet is made of steel plate to make a closed shell, and the electrical components of the incoming and outgoing circuit are installed in a drawer that can be withdrawn to form a functional unit that can complete a certain type of power supply task.
(4) Power and lighting distribution control box. Mostly closed vertical installation. Due to different use occasions, the enclosure protection level is also different. They are mainly used as power distribution devices at the production site of industrial and mining enterprises.
