  • Circuit breakers SF 1 to 40.5 kV Sulfr hexafluoride switchgear

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