A distribution cabinet is an electrical device used for receiving, distributing, and protecting electrical power, and is a core component of a power distribution system. In a complete power system, electricity typically enters a transformer from the grid or generating equipment and is then distributed.

It usually contains various electrical components inside, such as circuit breakers, busbars, and relays. These components work together to enable it to perform multiple functions, including power distribution, system control, and fault protection.

In practical applications, the distribution cabinet helps maintain power supply stability and enhances the overall safety of the system. It also allows operators to control individual circuits separately when maintenance or adjustments are required, thereby improving system flexibility and management efficiency.
