A distribution box is an electrical equipment used for distributing electrical energy, which has the functions of safety, convenience, and control of power supply.

Here are some detailed information about the distribution box:

1. Structural composition: The distribution box is usually composed of a metal cabinet, which is equipped with switch equipment, measuring instruments, protective appliances, and auxiliary equipment inside. These components are assembled in enclosed or semi enclosed spaces according to certain electrical wiring requirements.

2. Functional use: The main function of the distribution box is to connect, disconnect, and protect circuits. It can manually or automatically control circuit connections, and when the system malfunctions or operates abnormally, it can cut off the circuit or issue an alarm signal through protective appliances. At the same time, the measuring instruments inside the distribution box can display various parameters during operation and provide prompts or signals for deviations from normal working conditions.

3. Application scenario: Distribution boxes are widely used in various places such as homes, schools, hospitals, etc. It helps to manage and maintain the power system. Especially in the event of circuit failure, the distribution box is beneficial for quickly locating and repairing problems.

4. Classification method: According to different structures and purposes, distribution boxes can be divided into power distribution boxes, lighting distribution boxes, metering cabinets, etc. In addition, there are two forms: fixed type and drawer type. The former is commonly used in situations with dispersed loads and fewer circuits, while the latter is widely used due to its space saving, convenient maintenance, and multiple outgoing lines.

Overall, the distribution box is a key equipment to ensure the normal operation and safety of the power system. It not only improves the convenience of electricity use, but also ensures electricity safety.
