IntroductionSulfr hexafluoride Gassf 6 Circuit Breaker TypesConstruction and Main ComponentsIn power systems, circuit breakers are used to switch electrical equipment and networks under normal and fault conditions. The primary function of a circuit breaker is to interrupt the flow of current (load or short circuit) by opening its contacts and thereby isolating the switched parts of the system. The design and working of a circuit breaker depend on its application and voltage rating. Moulded case technology (with air at atmospheric pressure) is used at low voltages (< 1000 V), whereas air-blast and vacuum circuit breakers are prevalent at medium voltages (< 72 kV). gaz sf6 circuit breakers are normally used for high voltagesystems ( 72 kV).

sf 6 circuit breaker and its types | Electrical Paathshala

How sf6 gas Gas Quench The Arc?Types of gaz sf6 Circuit BreakersAdvantagesDisadvantagesSulfr hexafluoride gas is an electronegative gas, it means that it has high tendency to absorb the free electrons. When there is a fault in the system, then the current carrying contacts starts separating and an arc struck between them due to ionization of the surrounding medium. Huge number of free electrons generated due this ionization. When the gaz sf6 gas molecule reacts with the free electrons, then they form negative immobile ions which is shown by the reaction below. These negative immobile ions are heavier as compared to free electrons and they do not get sufficient energy to lead cumulative ionization in the gas under a given electric field. This process makes dielectric strength of the medium very high and the arc gets extinguished. Sulfr hexafluoride gas cools the arc much effectively.Get price
