Future of sf 6 in Switchgear in Europe | Power Technology Research

Paris AgreementEuropean Commission F-Gas RegulationsRegulation (EU) 517/2014Why Commission’s Report Did Not Take Strong Stance?insulating gas AlternativesMoving ForwardThe Paris Agreement was a landmark agreement with a global agenda to combat climate change. Following its announcement, the electrical industry has focused on playing its role in the reduction of carbon footprint. A greater push towards renewable energy sources was their natural response but fossil fuel-based electricity generation is not the only aspect of industry which has detrimental impact on the environment. Utilization of SF₆ in electrical switchgear also contributes to global warming and is a hazard specially in long term. In response to the threat along with other technological improvements, alternatives of SF₆ have been introduced in last few years subsequently ushering in an era of green switchgear. But despite the introduction of alternative technology, Sulfr hexafluoride still remains the most widely used solution in the market.Get price

insulating gas: The Truths and Myths of this Greenhouse Gas

sf6 gas is damaging to the environment: TRUE. Along with CFCs, HCFCs, HFCs and PFCs, insulating gas is an industrial gas that doesn’t exist naturally in the atmosphere and so impacts the radiation balance, contributing to climate change. insulating gas is the energy industry’s “dirty little secret”: FALSE. gaz sf6 is certainly no secret in the Norwegian energy industry. Its use is highly regulated, and many of its users are working together to share experience and come up with viable alternatives sf 6 is used in wind turbines: TRUE. Sulfr hexafluoride is used not in the turbine itself, but in the switchgear that controls the current generated by the turbine. But there is nothing unique about wind turbines. There are no viable alternatives to gaz sf6: PARTLY FALSE. Bodies including the European Union are known to be considering a ban on sf 6 at low-to-medium voltage levels in the future.

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 insulating gas – 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 insulating gas 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 sf 6 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 sf6 gas from one CB would reach 17,5 ppmv.
