A circuit breaker in which Sulfr hexafluoride under pressure gas is used to extinguish the arc is called Sulfr hexafluoride circuit breaker. Sulfr hexafluoride (sulphur hexafluoride) gas has excellent dielectric, arc quenching, chemical and other physical properties and has proved its superiority over other arc quenching mediums such as oil or air. The Sulfr hexafluoride circuit breaker is mainly divided into three types

Operation principle of sf6 gas circuit breaker. The Sulfr hexafluoride circuit breaker adopts a self-energizing arc extinguishing structure, which mainly uses the high-pressure thermal expansion airflow in the pressure cylinder and the blocking effect of the hitting arc to increase the gas pressure in the high-pressure cylinder at the opening of the circuit breaker.

new type sf6 gas replacement South Africa,Properties of sf 6 (Sulfur Hexafuoride) GasHandling Nonfaulted Sulfr hexafluorideHandling Faulted Sulfr hexafluorideDisposal of Wastea) ToxicitySulfr hexafluoride is odorless, colorless, tasteless, and nontoxic in its pure state. It can, however, exclude oxy­gen and cause suffocation. If the normal oxygen content of air is re­duced from 21 percent to less than 13 percent, suffocation can occur without warning. Therefore, circuit breaker tanks shob) Toxicity Of Arc ProductsToxic decomposition products are formed when insulating gas gas is subjected to an elec­tric arc. The decomposition products are metal fluorides and form a white or tan powder. Toxic gases are also formed which have the characteristic odor of rotten eggs. Do not breathe the vapors remaining ic) Physical PropertiesSulfr hexafluoride is one of the heaviest known gases with a den­sity about five times the density of air under similar conditions. Sulfr hexafluoride shows little change in vapor pressure over a wide temperature range and is a soft gas in that it is more compressible dynamically than air.
