NDIR sf6 gas Components Detection in high electrical switchgear

Aug 30, 2019 · An electron capture detector (ECD) is used to detect SF6 with high sensitivity below 1 ppmv. This device makes use of the high electron attachment coefficient of SF6, i.e. the ability to capture electrons. The free electrons to be attached to the SF6 molecules are created by a radioactive source. The ECD uses a radioactive emitter, typically, a metallic membrane coated with the radionuclide nickel.

  • SF6 gas in medium-voltage switchgear | TD Guardian Articles

    In this issue, we discuss the use of SF6 (sulfur hexafluoride) gas in medium-voltage switchgear. SF6 has been widely used in high-voltage circuit breakers for decades, but its use in medium-voltage is relatively recent. In the medium-voltage arena, SIemens uses SF6 gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.

  • Myth About SF6 Gas In Electrical Equipment

    Where is SF6 used? The following applications are known. For some of these most probably you haven’t heard of. For sound insulation in windows, In vehicle tyres, Is SF6 a health hazard? Pure SF6 is physiologically completely harmless for humans and animals. It’s even used in medical diagnostic. Due to its weight it might displace the oxygen in the air, if large quantities are concentrating in deeper and non ventilated places. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. What is the overall contribution of SF6 used in the electrical equipment to the greenhouse effect? Less than 0,1 % ( see CAPIEL) and CIGRE). In an Ecofys study the contribution to the greenhouse effect in Europe is estimated to 0.05 % (*).
