In normal operation, the circuit can be switched on or off by means of a manual or automatic switch. Classified by structural features and use: (1) fixed panel switch cabinets are often referred to as switchboards or switchboards. The front side of the switch cabinet has a protection effect, the back side and the side surfaces of the switch cabinet can still touch the charged part, the protection level is low, and the switch cabinet can only be used for industrial and mining enterprises with lower requirements on power supply continuity and reliability and is used for centralized power supply of a working and transformation room. (2) A protective (closed) switch cabinet refers to a low-voltage switch cabinet with all other sides closed except for a mounting surface. The electrical elements of the cabinet, such as switch, protection, monitoring and control, are all installed in a closed shell made of steel or insulating material and can be installed close to or away from the wall. Isolation measures are not needed to be added between each loop in the cabinet, and a grounded metal plate or an insulating plate can be adopted for isolation. Typically the door is mechanically interlocked with the main switch operation. In addition, a protective desk type switch cabinet (namely a control desk) is also arranged, and electrical appliances such as control, measurement, signals and the like are arranged on a panel. The protective switch cabinet is mainly used as a power distribution device in a process field. (3) A drawer type switch cabinet. The switch cabinet is made of steel plates to form a closed shell, and electrical elements of the wire inlet and outlet loop are all installed in the drawer capable of being pulled out to form a functional unit capable of completing a certain power supply task. The functional units are separated from the bus bars or cables by the grounded metal plates or plastic functional plates, so that three areas of the bus bars, the functional units and the cables are formed. There is also a separation between each functional unit. The drawer type switch cabinet has higher reliability, safety and interchangeability, and is an advanced switch cabinet, and most of the switch cabinets refer to the drawer type switch cabinet. The power distribution center is suitable for industrial and mining enterprises and high-rise buildings which require high power supply reliability and serves as a centralized control power distribution center. (4) Power, illumination distribution control box. Mostly closed vertical installation. The protection grades of the shells are different due to different use occasions. They are mainly used as power distribution devices in the production field of industrial and mining enterprises.
