The structure of a switchgear usually consists of a cabinet body, circuit breakers, isolation switches, load switches, operating mechanisms, transformers, and various protective devices. These components work together to achieve functions such as power on/off, conversion, and control. The cabinet body of the switchgear is usually made of steel plate, and is divided into multiple functional units inside, such as busbar room, circuit breaker room, cable room, relay room, and instrument room, to facilitate equipment installation and maintenance.

As a key guardian of the power system, high-voltage switchgear plays an important role in ensuring stable operation of the power system, improving equipment safety and reliability. With the continuous progress of technology and the continuous development of the power industry, the technology of high-voltage switchgear will also be constantly updated and improved, providing more solid technical support for the future development of the power system.
