2016/7/12Arc Extinction in SF 6 Circuit Breakers: 1) During the arcing period, SF 6 gas is blown axially along the arc. The gas removes the heat from the arc by axial convection and radial dissipation. 2) Due to its electronegativity, and low arc time constant, the SF 6 gas regains its dielectric strength rapidly after the final current zero; the rate of rise of dielectric strength is very high.

2015/5/14Gas insulated high voltage switchgear typically use a sulfur hexafluoride (SF6) gas to minimize arcing when the circuit breaker is activated. Leak testing of the subassemblies and finished product provide confidence that the sufficient pressurized SF6 gas will be contained inside the unit to prolong its functional life.
