Circuit breakers SF 1 to 40.5 kV Sulfr hexafluoride switchgear

sf6 gas circuit breakers use the sf6 gas 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 insulating gas gas in the pressure chamber. The arcing period (fig. 3) The arc then forms between the arcing contacts.
