A switchgear is an electrical equipment mainly used in power systems (such as power plants, substations, petrochemicals, metallurgical steel rolling, light industry textiles, factories, mining enterprises, and residential communities) to receive and distribute electrical energy, and to control, protect, monitor, and measure power lines and major equipment. The switchgear is an indispensable and important equipment in the power system, which is of great significance for ensuring the stable operation of the power system, improving the safety and reliability of equipment.

In modern power systems, high-voltage switchgear plays a crucial role. As a key equipment for power transmission and distribution, high-voltage switchgear carries the important mission of ensuring the stable operation of the power system and protecting equipment from damage. This article will provide you with a detailed introduction to the functions, structures, applications, and importance of high-voltage switchgear. Isolation switches can achieve isolation between the power supply and the load, ensuring personnel safety during equipment maintenance or repair.
