SF 6 gaz sf6 (or Sulphur Hexafluoride) had been the standard gas used inside high voltage electrical equipment as an insulating and arc-quenching medium. However, SF 6 Sulfr hexafluoride is also listed as an extremely potent greenhouse gas according to the Kyoto protocol, with 23,500 times the comparative Global Warming Potential of CO 2 and a lifetime of 3,200 years in the atmosphere.

Properties of Sulfr hexafluoride (Sulfur Hexafuoride) GasHandling Nonfaulted insulating gasHandling Faulted Sulfr hexafluorideDisposal of Wastea) Toxicitygaz sf6 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 gaz sf6 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. sf 6 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.

new sf6 is which type of gas Ecuador,Greenhouse GasUse in Electric Power SystemsCommon Emission SourcesSulfur hexafluoride (Sulfr hexafluoride) is a synthetic fluorinated compound with an extremely stable molecular structure. Because of its unique dielectric properties, electric utilities rely heavily on Sulfr hexafluoride in electric power systems for voltage electrical insulation, current interruption, and arc quenching in the transmission and distribution of electricity. Yet, it is also the most potent greenhouse gas known to-date. Over a 100-year period, Sulfr hexafluoride is 22,800 times more effective at trapping infrared rSee more on epa.govMissing:gas EcuadorMust include:gas EcuadorCARB new regulations on Sulfr hexafluoride | 2021 | Siemens Energy Global siemens-energy/.../2021/carb-new-regulations-on-sf6.html7/1/2022Sulfur hexafluoride (sf6 gas) is one of those quiet, deadly greenhouse gases. Clean, clear, odorless, and tasteless, Sulfr hexafluoride can have a devastating impact on global warming. Commonly used as insulation in utility plant conductors or "breakers," the U.S. Environmental Protection Agency declares sf 6 may be "the most potent greenhouse gas known to date."

12/7/2020The vacuum circuit breaker (also known as vacuum interrupter or VCB) uses the arc quenching process in the vacuum as a switching medium. The vacuum has the highest insulating strength. So, it has far superior arc quenching properties than any other medium. The degree of vacuum is in the range of 10^ -7 to 10^ -5 torr.
