How the distribution cabinet works
- 2019-05-23-

Regarding electric power construction, the design knows that there are many types of equipment needed. Let's look at the power distribution cabinet today. The models include: 10KV power distribution cabinet , 10KV power distribution cabinet.


The circuit diagram of the power distribution board is divided into a primary schematic diagram and a secondary schematic diagram. The primary schematic diagram is the main circuit schematic diagram. The secondary schematic is the schematic of the control circuit.

All electrical components and lines in the distribution board (box) should be in good contact and reliable connections; there should be no severe heating or burning. The door of the switchboard (box) should be intact; the door lock should be kept by someone.

Intelligent integrated distribution cabinets have made great improvements compared to these previous distribution cabinets! It is a technological innovation!

In view of the current situation of single-point failure prone to power distribution in the computer room, the most advanced technology achievements and hardware and software design are integrated. Committed to bringing a new experience to the construction and management of power distribution in computer rooms. It is mainly used in data centers and computer rooms such as finance, telecommunications, enterprises, and government. The capacity range is 30KVA-160KVA. The entire power distribution system adopts a standard network cabinet and modular structure design, with a variety of options, can be customized according to the actual needs of the computer room, customized high reliability products for customers. The intelligent power distribution cabinet monitors the current of each output branch in real time, and can set a pre-alarm value for the abnormality of the current of each output branch. Or human operation hidden dangers, to avoid overloading, the switch cuts off the power supply, causing the entire cabinet equipment to be powered off. In addition, the output shunt uses a hot-swap circuit breaker, which has the ability to adjust the phase of the power supply. It can easily realize the flexible adjustment of the three-phase imbalance. It can also increase the output shunt online and replace the switch under the condition of continuous power.


The requirements for the installation of power distribution boards (boxes) are: the power distribution boards (boxes) should be made of non-combustible materials; production sites and offices with low risk of electric shock can be installed with open-type power distribution boards; Poor processing workshops, castings, forgings, heat treatments, boiler rooms, woodworking rooms and other places should be installed with closed cabinets; in hazardous operating places with conductive dust or generating flammable and explosive gases, closed or explosion-proof types must be installed Electrical facilities; all electrical components, meters, switches and lines of the distribution board (box) should be neatly arranged, firmly installed and easy to operate. The floor of the board (box) installed on the floor should be 5 ~ 10 mm higher than the ground; the center height of the operating handle is generally 1.2 ~ 1.5m; there are no obstacles within the range of 0.8 ~ 1.2m in front of the board (box); the protection line is connected reliably; There must be no bare charged outside of (box); electrical components must be installed on the outer surface of the board (box) or on the distribution board, and there must be reliable screen protection.
