The working principle of the distribution cabinet mainly includes the following aspects:
Power supply source: The distribution cabinet is connected to the power supply through the main cable and obtains electrical energy supply from the power system.
Incoming switch: The incoming switch is used to control the input of electrical energy into the distribution cabinet. When the incoming switch is turned off, electrical energy enters the distribution cabinet for distribution and protection.
Power supply circuit: Multiple power supply circuits are installed inside the distribution cabinet, and each circuit is connected to a specific device or circuit. Control and protect the power supply circuit through fuses or circuit breakers, and branch circuits can also be set up under each power supply circuit to meet the needs of different equipment or circuits.
Distribution: The distribution cabinet distributes electrical energy to different circuits or equipment through switch devices such as circuit breakers and contactors. By controlling the switching devices, it is possible to achieve power switch control for different devices, which is convenient for operation and management.
Protection function: The distribution cabinet is equipped with various protection devices, such as fuses, circuit breakers, overload protectors, etc., to protect the power supply circuit and equipment. These protective devices can detect and cut off circuits in a timely manner to prevent damage to equipment and circuits caused by faults such as overcurrent, overload, and short circuit.
Control and Monitoring: The distribution cabinet can be equipped with control modules and monitoring equipment to control and monitor the power supply circuit and equipment operation status. For example, remote power-off or power on operations can be achieved through control modules, and real-time monitoring of parameters such as current and voltage can be achieved through monitoring devices to detect faults in a timely manner and take measures.
