Distribution box is data on the mass parameters, the general is a low pressure according to the electrical wiring, Lin asked to switch equipment, measuring instruments and protection of electric equipment and auxiliary equipment in a closed or semi-closed metal cabinet or on BingFu, constitute a low voltage distribution box. In normal operation, the circuit can be switched on or off by manual or automatic switch. 
Distribution box has small volume, convenient installation, technical performance, special fixed position, configuration features unique, without being limited by the space, the application is common, stable and reliable operation, high space utilization, less land and has the characteristics of environmental effect.
Distribution box has small volume, convenient installation, technical performance, special fixed position, configuration features unique, without being limited by the space, the application is common, stable and reliable operation, high space utilization, less land and has the characteristics of environmental effect. Is command power of various components of the circuit to be reasonable allocation of power control center, is a reliable power source is to accept the top, right feed electricity load control links, was the key to obtain users satisfied with the quality of power supply or not. To improve the operation reliability of power distribution box is the target of high quality engineering.
Use of distribution box: reasonable distribution of electrical energy, convenient operation of the circuit. High level of safety protection, the intuitive display of the circuit.
Classification of structural features and USES:
(1) fixed panel switch cabinet, often called switchboard or distribution screen. It is a kind of outdoor switchgear panel block, positive has protective effect, and on the back side can still hit a live part, protection grade is low, can only be used for low power supply continuity and reliability requirements of industrial and mining enterprises, for substation room centralized power supply. (2) the protective type (i.e. closed) switch cabinet, which refers to a low-voltage switchgear that has been enclosed by all other sides except the installation surface. This cabinet of switches, protection and monitoring control and other electrical components are installed in a closed shell made of steel or insulating material, reliable walls or wall mounted. Each circuit in the cabinet can be separated by means of isolation, or the grounded metal plate or insulation board can be used. Usually the door has mechanical interlock with main switch operation. In addition, there are protective type switch cabinets (namely the console), which are equipped with control, measurement, signal and other electrical appliances. The protective switch cabinet is mainly used as a power distribution device in the process field. (3) drawer open switch cabinet. This kind of switch cabinet USES steel plate to make a sealed shell, the electric element that enters the circuit circuit is installed in the drawer that can pull out, compose can complete a certain kind of power supply task function unit. The functional unit is separated from the busbar or the cable, separated by a functional plate made of earthing metal or plastic, forming a bus, functional unit and cable. There are also isolation measures between each functional unit. The drawer type switchgear has high reliability, safety and interchangeability, is the more advanced switch cabinet, the switch cabinet mostly refers to the drawer type switch cabinet. They can be used to require high reliability of industrial and mining enterprises and high-rise buildings as centralized control distribution centers. (4) power and lighting distribution control box. Mostly enclosed vertical installation. The protection level of the shell is different because of different use cases. They are mainly used as the distribution device for the production site of industrial and mining enterprises.
Principle: the distribution box shall be installed in a closed or semi-closed metal cabinet or screen in accordance with the electrical wiring requirements to assemble the switch equipment, measuring instruments, protective appliances and auxiliary equipment, and constitute a low-voltage distribution box. In normal operation, the circuit can be switched on or off by manual or automatic switch. To cut off the circuit or alarm with the aid of a protective device when failure or abnormal operation. The measuring instrument can show the various parameters in operation, and can adjust some electrical parameters to signal or signal the deviation of normal working status.
