On the difference between distribution box and distribution cabinet

1、 Conceptual distinction

1. Distribution box

The distribution box is a small power distribution box, which contains power switch and safety device. The structure is relatively simple and is mostly used for terminal power distribution. The distribution box is the last level of power distribution facilities in the power supply system. A distribution box can be a power incoming line and multiple power supply output circuits. The power supply output circuits are led from the distribution box to each power load. Because the volume of the distribution box is small and can not be put into large distribution equipment, the capacity of the distribution box is small. Generally, one distribution box is used for 4-8 small loads, The distribution box is arranged in the center of the power supply load and sends power to the load with cables or wires.

2. Distribution cabinet

Distribution cabinet is the upper level of distribution equipment of distribution box. Its volume is large, and large electrical equipment can be put in it. Therefore, it is generally used as distribution equipment with medium capacity load, including distribution box, motor, etc. its applicable capacity is different in various process fields, generally ranging from several kilowatts to dozens of kilowatts. On the basis of leakage protection and short-circuit protection provided by the traditional distribution box, it also provides overvoltage protection, ignition and power failure, lightning protection, automatic power supply, temperature protection, power limitation, fault recording, self inspection function, learning and memory, mobile interconnection visualization and digitization.

2、 Functional distinction

In short, the box for distributing electric energy is called distribution box. The distribution box is mainly used for controlling and distributing electric equipment and protecting the overload, short circuit and leakage of lines. The distribution box is installed in various places, such as schools, organs, hospitals, factories, workshops, families, etc., such as lighting distribution box, power distribution box, etc. The distribution box is small and can be concealed in the wall and stand on the ground.

Both distribution box and distribution cabinet are indispensable infrastructure in people's daily life. At present, some people do not realize the importance of distribution boxes and cabinets, arbitrarily shelve items on them, or even maliciously damage them, causing no small damage to distribution facilities, which is not conducive to the development of power grid circuit system. Shenzhen Wuyi lighting equipment Co., Ltd. specializes in the production of LED display intelligent distribution cabinet, PLC remote control distribution cabinet, multi-function card distribution cabinet, construction site construction distribution cabinet, rental mobile rental distribution cabinet, xl-21 series power distribution cabinet, GGD low-voltage complete distribution cabinet, various stainless steel distribution boxes, distribution cabinets, wall mounted control type, outdoor rain proof box, indoor distribution box Exposed distribution box, concealed distribution box and various customized non-standard boxes.

Difference between control box and distribution box

The control box is suitable for low-voltage power grid system with AC 50Hz and rated working voltage of AC 380V in factories, mines, enterprises, shopping malls, hotels, schools, airports, ports, hospitals, high-rise buildings and living quarters. It is used for power, lighting power distribution and motor control. It is suitable for indoor wall hanging and outdoor floor mounted power distribution equipment. The control box is also applicable to the power system with AC 50Hz and voltage below 500V as fire pump control, submersible pump control, fire fan control, fan control, lighting distribution control, etc. the control modes include direct start control, star delta step-down start control, self coupling step-down start control, frequency converter start control, soft start control and other control modes, Disconnectors and fuse switches can also be used as isolation breakpoints.

The distribution box is to assemble the switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi closed metal cabinet or panel according to the electrical wiring requirements to form a low-voltage distribution device. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switch. In case of fault or abnormal operation, cut off the circuit or alarm with the help of protective appliances. The measuring instrument can display various parameters in operation, adjust some electrical parameters, and prompt or send signals for deviation from the normal working state. It is commonly used in various power generation, distribution and substation.
