Power distribution: Low Voltage Distribution Cabinet is responsible for distributing the power from the transformer or generator to various power loads, such as motors, lighting, power equipment, etc. It ensures that the power can be safely and stably supplied to each load.
Load management: By reasonably configuring the circuit breakers or fuses in the distribution cabinet, the load balance of each branch circuit is ensured to avoid overload.
2. Protection function
Overload protection: The distribution cabinet is equipped with overload protection devices (such as circuit breakers and fuses), which can automatically cut off the power supply when the load is too large to prevent equipment damage and fire accidents.
Short circuit protection: By quickly cutting off the current in the event of a short circuit, the distribution system and power equipment are protected to avoid serious accidents and the losses caused by them.
Leakage protection: A leakage protector is installed in the distribution cabinet to monitor the leakage current. Once leakage is found, the power supply will be cut off in time to ensure personal safety.
3. Monitoring and management
Power quality monitoring: Some advanced Low Voltage Distribution Cabinet are equipped with a power monitoring system, which can monitor voltage, current, power quality and other parameters in real time, provide data analysis, and help manage the performance of the power system.
Status indication and alarm: The distribution cabinet is usually equipped with indicator lights and alarm devices to display the operating status of the equipment and alarm in time under abnormal conditions, which is convenient for operation and maintenance personnel to check and handle.
4. Control function
Remote control and automation: Modern Low Voltage Distribution Cabinet can be integrated with the monitoring system to realize remote control and automatic management, and improve the management efficiency of the power system.
Control of motors and other equipment: The distribution cabinet can integrate motor controllers (such as soft starters and inverters) to realize the start and stop and speed control of the motor.
5. Safety isolation
Safety isolation: Low Voltage Distribution Cabinet is designed with multiple safety isolation measures to ensure the safety of inspection and maintenance personnel, avoid operation under power, and reduce the risk of electric shock.
Protection level: Low Voltage Distribution Cabinet usually has a certain protection level (such as IP level) to prevent external factors such as dust and water from affecting internal equipment and improve the reliability and safety of equipment.
6. System expansion
Flexible scalability: The design of Low Voltage Distribution Cabinet usually takes into account the needs of future expansion, and can easily add or adjust distribution circuits according to actual power consumption and load changes.
Low Voltage Distribution Cabinet is not only responsible for the efficient distribution and protection of electric energy in the power system, but also undertakes multiple functions such as monitoring, control and safety isolation. Through the effective combination of these functions, Low Voltage Distribution Cabinet greatly improves the safety, reliability and operation efficiency of the power system, ensuring that users can use electricity safely in a stable power environment.
