Basic Overvie
The distribution box receives electrical energy from the power source, usually obtained from the mains power grid or power generation equipment.
For three-phase electricity, their colors are yellow, green, and red, representing A, B, and C phases respectively;
For single-phase electricity, red or brown wires are generally used to represent the live wire (L), blue or black wires to represent the neutral wire (N),
and yellow green dual color wires to represent the ground wire (PE).
The electrical energy is introduced into the distribution cabinet through the busbar, which is a conductive metal busbar used to connect
and distribute electrical energy in the distribution box. It has good conductivity and mechanical strength, and can carry large currents.
Advantages And Characteristics
High safety:
The internal circuits of the distribution box are insulated to effectively prevent external interference and short circuits,
and better protect personnel safety. In addition, it also has electrical safety protection functions such as leakage, overcurrent, and overvoltage.
Compact size:
The distribution box panel integrates the original circuit control parts according to certain standards, with a small size,
easy installation, no site constraints, and convenient inspection and control.
Intelligent management:
The intelligent distribution box introduces mobile internet technology, which can be remotely accessed through mobile phones PAD、 Real time monitoring
and management of various electrical lines in the home by computers, timely detection and handling of electrical faults.
High protection level:
Distribution boxes are usually made of high-quality materials, with a tight overall structure and good protection performance,
which can effectively prevent power safety accidents such as leakage, arc, short circuit, and overload.
Stable and reliable operation:
During normal operation, the circuit can be connected or disconnected using manual or automatic switches;
When there is a malfunction or abnormal operation, use protective appliances to cut off the circuit or sound an alarm;
Measuring instruments can display various parameters during operation, adjust certain electrical parameters,
and provide prompts or signals for deviations from normal working conditions.
Manual control:
Operators can manually operate switch devices such as knife switches, circuit breakers, etc. through handles, buttons, etc.
to connect or disconnect circuits, thereby achieving start stop control of electrical equipment.
For example, in the lighting distribution box, the lighting fixtures can be manually switched on and off.
Automatic control:
using automatic switching devices such as relays and contactors to automatically control the on/off of circuits according to preset conditions or instructions.
For example, timing control can be achieved through time relays, allowing certain devices to operate within specified time periods;
Remote control can be achieved through intermediate relays, allowing operators to control the equipment from a distance away from the distribution cabinet.
Power Supply Structure:
Single - phase power has one live wire and one neutral wire.
Three - phase power usually has three live wires, and in a three - phase four - wire system, there is also one neutral wire.
Voltage Level:
The voltage of single - phase power is typically 220V. For three - phase power, the line - to - line voltage is generally 380V,
and the line - to - neutral voltage is 220V.
Power Transmission Capacity:
Three - phase power can transmit more power over the same distance with lower losses and is more suitable for high - power equipment.
Single - phase power is mainly used for low - power household appliances and small - scale equipment.
Application Scenarios:
Single - phase power is commonly used in homes and small commercial places.
Three - phase power is widely applied in industrial factories, large - scale commercial buildings, and for high - power machinery.

Application areas
Manufacturing industry:
Production equipment, automated assembly lines, CNC machine tools, etc. in various factories require stable and reliable power supply.
Distribution boxes distribute power to various production equipment and have functions such as overload protection and short circuit protection
to ensure the normal operation of equipment and prevent production interruption or equipment damage caused by electrical faults.
Public buildings:
Schools, hospitals, libraries, sports centers, subway stations, and other public buildings require a large amount of electricity to maintain daily operations,
such as lighting, medical equipment operation, elevator operation, fire protection systems, etc.
The distribution box is responsible for the reasonable distribution and protection of this electricity.
Mining industry:
