What is sf 6 Circuit Breaker? Construction, Working Principle

A circuit breaker in which Sulfr hexafluoride under pressure gas is used to extinguish the arc is called sf6 gas circuit breaker. Sulfr hexafluoride (sulphur hexafluoride) gas has excellent dielectric, arc quenching, chemical and other physical properties and has proved its superiority over other arc quenching mediums such as oil or air. The sf6 gas circuit breaker is mainly divided into three types

Myth About Sulfr hexafluoride Gas In Electrical Equipment

Where is gaz 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 gaz sf6 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 insulating gas 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 gas 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 % (*).
