As the core guardian of the power system, the distribution box plays a crucial role in the transmission and distribution of electricity. By understanding its definition, function, classification, working principle, and application fields, we can better understand and use distribution boxes, providing strong guarantees for the stable operation of the power system.

The distribution box mainly consists of an outer shell, partitions, wiring terminals, switch circuit breakers, leakage protectors, and other parts. The shell is usually made of metal materials such as steel plate or aluminum alloy, which have protective and anti-corrosion properties; Partitions are used to isolate different components or power sources, ensuring circuit safety and reliability; Terminal blocks are used to receive wiring for incoming and outgoing lines and various circuit incoming lines; The switch circuit breaker is one of the key components for protecting the safety of distribution boxes and circuits; Leakage protectors are used for real-time monitoring of current values in circuits, automatically detecting leakage faults and implementing automatic tripping.
