The distribution box is a massive parameter in the data. It generally constitutes a low-voltage forest according to the electrical wiring. It requires switching equipment, measuring instruments, protection electrical appliances and auxiliary equipment. It is assembled in a closed or semi-closed metal cabinet or on a screen to form a low-voltage distribution box. During normal operation, the circuit can be connected or disconnected with the help of a manual or automatic switch.
Purpose
Edit
The purpose of the distribution box is to distribute electric energy reasonably and facilitate the opening and closing of circuits. It has a high level of safety protection and can visually display the conduction status of the circuit.
Classification
Commonly used distribution boxes are made of wood and metal. Because the protection level of metal distribution boxes is higher, metal is used more often.
Classified by structural characteristics and uses
Fixed panel switch cabinet, often called switch panel or distribution panel. It is an open-type switch cabinet with a panel shield. It has a protective function on the front, but the back and sides can still touch the live parts. The protection level is low and can only be used in industrial and mining enterprises with low requirements for power supply continuity and reliability. For centralized power supply in the substation room. Protective or enclosed switch cabinet refers to a low-voltage switch cabinet in which all sides except the installation surface are enclosed. The electrical components such as switch protection, monitoring and control of this kind of cabinet are installed in a closed shell made of steel or insulating materials, and can be installed on or off the wall. There may be no isolation measures between each circuit in the cabinet, or a grounded metal plate or insulating plate may be used for isolation. Usually the door is mechanically interlocked with the main switch operation. In addition, there is a protective bench-type switch cabinet, that is, the control panel is equipped with electrical appliances such as control and measurement signals. Protective switch cabinets are mainly used as power distribution devices at process sites. Drawer switch cabinet. This type of switch cabinet uses a steel plate to make a closed shell, and the electrical components of the incoming and outgoing circuits are installed in pull-out drawers to form a functional unit that can complete a certain type of power supply task. Functional units and busbars or cables are separated by grounded metal plates or functional boards made of plastic, forming three areas of busbar functional units and cables. There are also isolation measures between each functional unit. Drawer-type switch cabinets have high reliability, safety and interchangeability, and are relatively advanced switch cabinets. Most switch cabinets refer to drawer-type switch cabinets. They are suitable for high-rise buildings in industrial and mining enterprises that require high power supply reliability, and serve as centralized control power distribution centers. Power lighting distribution control box. Most are closed vertical installations. Due to different use occasions, the protection level of the shell is also different. They are mainly used as power distribution devices at the production sites of industrial and mining enterprises.
