(1) Distribution box
The distribution box is a small power distribution box that contains power switches and fuses. The structure is relatively simple, and is mostly used for terminal power distribution. The distribution box is the last-level power distribution facility in the power supply system. One distribution box can be a power supply line and multiple power supply output circuits. The power supply output circuit is led from the distribution box to each power load, due to the distribution box. The volume is small and cannot be placed in large power distribution equipment, so the capacity of the distribution box is not large. Generally, 4-8 small loads use one distribution box, and the distribution box is placed in the center of the power supply load, with cable or The wires send electricity to the load.
(2) Distribution cabinetThe power distribution cabinet is the upper-level power distribution equipment of the power distribution box. It has a large volume, and can be placed into a large electrical equipment. Therefore, it is generally used as a power distribution equipment with medium capacity load, including distribution boxes and motors. Its applicable capacity varies from process to process, typically from a few kilowatts to tens of kilowatts. On the basis of the leakage protection and short-circuit protection provided by the traditional distribution box, it also provides over-voltage protection, ignition and power-off, lightning protection, automatic power supply, temperature protection, power limitation, fault record, self-check function, learning memory, and mobile internet.

2 functional distinction
Simply put, the box that distributes electrical energy is called the distribution box. The distribution box is mainly used for the control and distribution of the electrical equipment, and it protects the overload, short circuit and leakage of the line. The distribution box is installed in various places, such as schools, institutions, hospitals, factories, workshops, homes, etc., such as lighting distribution boxes, power distribution boxes, and so on. The distribution box is small in size and can be concealed inside the wall and can stand on the ground.
Whether it is a distribution box or a power distribution cabinet, it is an indispensable infrastructure in people's daily lives. Now some people are not aware of the importance of distribution boxes and distribution cabinets, and arbitrarily place items on them, even malicious damage, causing no small damage to the distribution facilities, which is not conducive to the development of the grid circuit system. Shenzhen Dance Art Lighting Equipment Co., Ltd. specializes in producing LED display intelligent power distribution cabinet, PLC remote control power distribution cabinet, multi-function card power distribution cabinet, construction site construction power distribution cabinet, rental mobile rental power distribution cabinet, XL-21 series power Power distribution cabinet, GGD low voltage power distribution cabinet, various stainless steel distribution boxes, power distribution cabinets, wall-mounted control, outdoor rainproof boxes, indoor distribution boxes, bright assembled electrical boxes, dark assembled electrical boxes And custom-made all kinds of non-standard boxes.
Second, the difference between the control box and the distribution box
The control box is suitable for opening factories, mines, enterprises, shopping malls, hotels, schools, airports, ports, hospitals, high-rise buildings, living quarters, etc., AC 50HZ, rated working voltage is 380V AC low-voltage power grid system, as power, lighting distribution and For motor control, it is suitable for indoor wall-mounted and outdoor floor-mounted power distribution equipment. The control box is also suitable for AC 50HZ, power system below 500V as fire pump control, submersible pump control, fire fan control, fan control, lighting distribution control, etc. The control mode has direct start control, star triangle step-down start control, Various control modes such as self-starting step-down control, inverter start control, and soft start control can also be used as isolation break points for disconnectors and fuse switches.
The distribution box is to assemble the switchgear, measuring instrument, protective appliance and auxiliary equipment in the closed or semi-closed metal cabinet or the screen according to the electrical wiring requirements to form a low-voltage power distribution device. In normal operation, the circuit can be switched on or off with the aid of a manual or automatic switch. In the event of malfunction or abnormal operation, the circuit or alarm is cut off by means of a protective device. The measuring instrument can display various parameters during operation, and can also adjust some electrical parameters to prompt or signal the deviation from the normal working state. Commonly used in various hair, distribution, and substation.
