The power distribution cabinet is a massive amount of parameter data, which generally constitutes a low-voltage forest. According to the electrical wiring requirements, the switchgear, measuring instruments, protection devices and auxiliary equipment are assembled in a closed or semi-closed metal cabinet or board to form a low-voltage distribution box.
1. From the point of view of use, the distribution box is generally used for household use, while the electrical control cabinet is mainly used for centralized power supply such as industrial electricity and building electricity. Distribution boxes, distribution cabinets for complete sets of equipment, distribution boxes for low-voltage complete sets of equipment, distribution cabinets are divided into two types: high and low voltage.
2. The basic difference between appearance and size is size. The switchboard is on the floor, the size of a refrigerator. The distribution box is as small as a box fixed to the wall and serves the same purpose.
3. The distribution box is generally a terminal product, and the standard GB7251 3 is applicable. The maximum current for non-professional operation is 250A. Power distribution cabinets are generally used to control and distribute electrical energy, and the applicable standards are different.
4. The official name of the power distribution cabinet is vertical cabinet, and the power distribution box is box type.
5. The power distribution cabinet can be equipped with various explosion-proof electrical appliances or combinations of explosion-proof electrical appliances in function, such as explosion-proof power supply (lighting) distribution box, explosion-proof electromagnetic starter, explosion-proof power supply maintenance box, etc.; the distribution box can be equipped with circuit breakers, contactors , thermal relays, buttons, indicators and other components for lighting and power motor control.
