  • Circuit breakers SF 1 to 40.5 kV SF6 switchgear

    SF6 circuit breakers use the 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 SF6 gas in the pressure chamber. The arcing period (fig. 3) The arc then forms between the arcing contacts.

  • Sulfur hexafluoride circuit breaker - Wikipedia

    Current interruption in a high-voltage circuit breaker is obtained by separating two contacts in a medium, such as sulfur hexafluoride (SF 6), having excellent dielectric and arc-quenching properties. After contact separation, current is carried through an arc and is interrupted when this arc is cooled by a gas blast of sufficient intensity.

  • Drying and particle filters absorb moisture, gas and dust

    On the suspicion that SF 6 gas in a circuit breaker is contaminated or humid, we strongly recommend the use of drying and particle filters between switchgear and service cart. Moisture and both gaseous and dusty decomposition products as well as oil aerosols are adsorbed by special drying and particle filters during the recovery operation. Thus, service carts are protected effectively against contamination as most of the moisture and decomposition products are collected by the prefilter units.
