1000KVA Low Voltage Substation Distribution Panel

The working principle of low-voltage distribution cabinet starts from the access point of power supply, that is, the incoming cabinet. Once the power is connected to the incoming cabinet, it is distributed to each outgoing cabinet through the busbar system. The busbar is the current transmission component in the distribution cabinet, usually made of highly conductive materials (such as copper or aluminum), which can effectively transmit current to each branch. The outgoing cabinet is equipped with components such as circuit breakers and contactors, which perform circuit connection and disconnection operations according to control signals. The circuit breaker automatically disconnects when the circuit is overloaded or short-circuited to prevent damage to the circuit; while the contactor is used to frequently connect or disconnect the circuit as needed. In addition, the low-voltage distribution cabinet is also equipped with various protection devices, such as relays and fuses, which can monitor the circuit status in real time and take protective measures quickly in abnormal situations. Relays switch circuits based on specific input signals (such as current, voltage or temperature), while fuses automatically cut off the circuit when the current exceeds its rated value to protect electrical equipment from damage. These measures together improve the operating efficiency and safety of the power system.
