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.

High voltage switchgear is an electrical equipment used in the power system to connect, disconnect, carry, and disconnect normal and fault currents. It is mainly used in the distribution system of power plants, substations, petrochemicals, metallurgy and steel rolling, light industry and textile industries to control and protect the power system. The main functions of high-voltage switchgear include controlling the opening and closing of power supply, distributing electrical energy, protecting equipment and circuits from damage, etc.
