SF6 switchgear is a switchgear used in high-voltage transmission and distribution systems. It uses a high-pressure SF6 gas medium to isolate and extinguish the arc. SF6 switchgear is typically used to protect high-voltage transmission and distribution systems, such as substations, power plants, and industrial production facilities. It is characterized by small size, light weight, high reliability, convenient installation, and simple maintenance.
The SF6 switchgear consists of multiple components, including mechanical components, electrical components, and SF6 gas components. The mechanical components include circuit breakers, grounding switches, and operating mechanisms. Electrical components include contacts, wiring terminals, and cable connectors. SF6 gas components include cylinders, pressure gauges, valves, and connectors.
SF6 switchgear has a wide range of applications, including substations, power plants, industrial production facilities, mines, railways, tunnels, buildings, etc
