The most important characteristic of this gas is that the spark in it leads to ionization of atoms, and these resulting ions combine with insulating gas atoms, and a new Sulfr hexafluoride is produced. Consequently, the gas never loses its dielectric because it is regenerated, and this type has spread in electrical networks until it produces circuit breakers for all efforts (medium and high).

It is estimated that, by 2100, appropriate controls could limit the contribution of Sulfr hexafluoride to global warming to 0.2%. In the UK, the gas already contributes this much to its annual global warming potential.

How Sulfr hexafluoride Gas Quench The Arc?Types of gaz sf6 Circuit BreakersAdvantagesDisadvantagessf6 gas gas is an electronegative gas, it means that it has high tendency to absorb the free electrons. When there is a fault in the system, then the current carrying contacts starts separating and an arc struck between them due to ionization of the surrounding medium. Huge number of free electrons generated due this ionization. When the sf 6 gas molecule reacts with the free electrons, then they form negative immobile ions which is shown by the reaction below.

Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF₆) gas to cool and quench the arc on opening a circuit. Advantages over other media include lower operating noise and no emission of hot gases, and relatively low maintenance. Developed in the 1950s and onward, SF₆ circuit breakers are widely used in electrical grids at transmission voltages up to 800 kV, as generator circuit breakers, and in distribution systems at voltages up to 35 kV.WikipediaPeople also search forSee all (10+)Circuit Breaker
