  • Health and environmental dangers of sf6 gas-filled switchgear

    Sulphur hexafluoride (SF 6) is an inorganic, colourless, odourless, non-flammable, heavy gas that has been widely-regarded as an excellent electrical insulator [1]. However, although SF 6 is inert during normal use, highly toxic by-products are produced that pose a serious health threat to the workers who come into contact with them when electrical discharges occur through everyday usage within SF 6 -filled equipment [2].

    Sulphur hexaflouride (Sulfr hexafluoride) gas has been used in MV and HV switchgear for many years. It is said to be highly toxic and a potent greenhouse gas. It is used because of its excellent electrical insulation properties, but recently some switchgear companies have suggested other solutions.

  • Electric Power Systems Partnership | Fluorinated Gas

    Emission SourcesMitigation OptionsRelevant LinksFrequent QuestionsThe most common use for gaz sf6, both domestically and internationally, is as an electrical insulator in high voltage equipment that transmits and distributes electricity. Since the 1950’s, the U.S. electric power industry has used gaz sf6in circuit breakers, gas-insulated substations and other switchgear used in the transmission system to manage the high voltages carried between generating stations and customer load centers. Several factors affect insulating gas emissions from electric power systems, such as the type and age of the gaz sf6-containing equipment (e.g., old circuit breakers can contain up to 2,000 pounds of sf6 gas, while modern breakers usually contain less than 100 pounds) and the handling and maintenance procedures practiced by electric utilities. Because of its long life span and high global warming potential (GWP), even a relatively small amount of gaz sf6can impact the climate. The electric power industry uses roughly 80 percent of all Sulfr hexafluoride produced worldwide. Ideally, none of this gas would b...

    Nov 11, 2015 · Sulfur hexafluoride (SF 6) is widely utilized in gas-insulated switchgear (GIS). However, part of SF 6 decomposes into different components under partial discharge (PD) conditions. Previous research has shown that the gas responses of intrinsic and 4 Å-type molecular sieve-deposited multi-wall carbon nanotubes (MWNTs) to SOF 2 and SO 2 F 2 , two important decomposition components of SF 6 , are not obvious.
