Myth About sf 6 Gas In Electrical Equipment

Where is sf 6 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 Sulfr hexafluoride a health hazard? Pure Sulfr hexafluoride 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 Sulfr hexafluoride 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 Sulfr hexafluoride 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 % (*).

Three abnormal situations leading to an uncontrolled release

Abnormal LeakageInternal FaultExternal FireThe method of risk assessment is similar to that used in section “leakage from gaz sf6 – filled equipment” which deals with normal leakage. The same case study data will be used for high and medium voltage situations. In the calculations that follow it is assumed that all of the gaz sf6 in one circuit-breaker escapes suddenly and it is again assumed that the switch-room is sealed and that ventilation is inoperative. (see figure 1). In practice, attention would be drawn to an abnormal leak by underpressure detectors fitted to the CBs. These normally operate around 80% of normal filling pressure, and at this point in time, only 20% of the available Sulfr hexafluoride would be in the atmosphere, leading to an SOF2concentration of 1,8 ppmv. In the case of abnormal leakage of Sulfr hexafluoride in a medium voltage indoor substation (see figure 2 ), the SOF2 related to complete escape of gaz sf6 from one CB would reach 17,5 ppmv. The concentration of SOF2in the switchroom at 20% relative pressure loss (commonly the alarm level) w...Get price
