Circuit breakers SF 1 to 40.5 kV sf 6 switchgear

gaz sf6 circuit breakers use the gaz sf6 auto-compression technique. The main contacts and the arcing contacts are initially closed (fig. 1). Pre-compression (fig. 2) When the contacts begin to open, the piston slightly compresses the Sulfr hexafluoride gas in the pressure chamber. The arcing period (fig. 3) The arc then forms between the arcing contacts.

Sulfur hexafluoride (SF 6) is an inorganic, colorless, odorless, non-flammable, extremely potent greenhouse gas which is an excellent electrical insulator. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. SF 6 is used in the electrical industry as a gaseous dielectric medium for high-voltage circuit breakers, switchgear, and other electrical equipment, often replacing oil filled circuit breakers (OCBs) that can contain harmful PCBs.
