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 installation and maintenance of distribution boxes are crucial for their normal operation and service life. When installing the distribution box, it is necessary to choose a suitable installation location to ensure the safety and reliability of the distribution box. At the same time, it is also necessary to choose appropriate distribution box models and specifications based on electricity demand. When maintaining the distribution box, it is necessary to regularly check the working status of the internal components of the distribution box, and promptly identify and solve problems. In addition, it is necessary to regularly clean and maintain the distribution box to ensure its good operating condition and long service life.

The distribution box has a protective function, which can automatically cut off the power supply in case of short circuit fault or abnormal situation of electrical equipment; It also has an indicator function, and the indicator lights on the panel can emit red, green, and yellow light to display the circuit status; In addition, the distribution box can also perform operations such as conversion switches, isolation transformers, measuring instruments, and branch circuit breakers.

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.
