First, the conceptual difference.
1. The distribution box is a small power distribution box, which contains a power switch and a safety device. The structure is relatively simple, mostly used for terminal power distribution.
Distribution box is the last level of distribution facilities, power supply system in a distribution box can be a power supply into line and multiple output power supply circuit, the output from the distribution box power supply circuit to the power load, due to the smaller distribution box, cannot be put into the large power distribution equipment, so the capacity of the distribution box is not large, usually four to eight distribution box with a small load, The distribution box is located in the center of the supply load, and the power is delivered to the load by cables or wires.
2, the distribution cabinet is the distribution box on the level of distribution equipment, its volume is large, which can be put into the larger electrical equipment, so it is generally used as a medium capacity load distribution equipment, including the distribution box, motor, etc., its applicable capacity is different in each process field, generally in a few kilowatts to dozens of kilowatts.
On the basis of leakage protection and short circuit protection provided by the traditional distribution box, it also provides over-voltage protection, ignition power off, lightning protection, automatic power supply, temperature protection, power limitation, fault recording, self-check function, learning and memory, visualization and digitization of mobile Internet and other functions.
Second, the difference in function.
In brief, the distribution of electric energy box is called the distribution box. The distribution box is mainly used for the control and distribution of electrical equipment. It plays a protective role in the overload, short circuit and leakage of the line. Distribution boxes are installed in various places, such as schools, institutions, hospitals, factories, workshops, families, etc., such as lighting distribution boxes, power distribution boxes, etc. Distribution box is small in size, can be hidden in the wall, can stand on the ground.
Whether the distribution box or the distribution cabinet is a necessary infrastructure in People's Daily life. Now some people do not realize the importance of distribution box, distribution cabinet, arbitrarily on the use of items, or even malicious damage, to the distribution facilities caused a lot of damage, is not conducive to the development of the power grid circuit system.
