1. Introduction What is a distribution box? A total circuit distribution box for all consumer electricity. plc splitter application plc splitter application
2. Working principle The distribution box is a low-voltage power distribution device that assembles switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on the screen according to the electrical wiring requirements. During normal operation, the circuit can be switched on or off by means of manual or automatic switches. In the event of failure or abnormal operation, the circuit can be cut off or alarmed by means of protective appliances. By means of measuring instruments, various parameters in operation can be displayed, and some electrical parameters can also be adjusted to prompt or send signals for deviations from the normal working state. It is often used in various hair, distribution and substations. plc splitter application plc splitter application
3. Purpose It is easy to manage, and it is helpful for maintenance when a circuit failure occurs. Distribution box and distribution cabinet distribution board distribution certificate, etc., is a complete set of equipment for centralized installation of switches, meters and other equipment. The commonly used distribution boxes are made of wood and iron. Nowadays, the electricity consumption is quite large, so iron is used more. The purpose of the distribution box: Of course, it is convenient to stop and transmit electricity, and it plays the role of measuring and judging the stop and transmission of electricity. plc splitter application plc splitter application
4. Classification 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 (that is, closed) switchgear refers to a low-voltage switchgear in which all sides are closed 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. There may be no isolation measures between each circuit in the cabinet, or a grounded metal plate or insulating plate can be used for isolation. Usually the door is mechanically interlocked with the main switch operation. In addition, there is a protective table-type switch cabinet (ie console), and the panel is equipped with electrical appliances such as control, measurement, and signal. The protective switchgear is mainly used as a power distribution device on the process site. (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. The functional unit and the bus bar or cable are separated by a grounded metal plate or a functional plate made of plastic to form three areas of bus bar, functional unit and cable. There are also isolation measures between each functional unit. Drawer switchgear has high reliability, safety and interchangeability, and is a relatively advanced switchgear. Most of the switchgear currently produced are drawer switchgear. They are suitable for industrial and mining enterprises and high-rise buildings that require high reliability of power supply, as centrally controlled distribution centers. (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. plc splitter application plc splitter application
