Operating PrincipleBrief HistoryDesign FeaturesGenerator Circuit BreakersHigh Power TestingIssues Related to SF6 Circuit BreakersComparison with Other TypesCurrent interruption in a high voltage circuit breaker is obtained by separating two contacts in a medium, such as sulfur hexafluoride (SF6), having excellent dielectricand arc quenching properties. After contact separation, current is carried through an arc and is interrupted when this arc is cooled by a gas blast of sufficient intensity. SF6 gas is electronegativeand has a strong tendency to absorb free electrons. The contacts of the …See more on en.wikipedia.orgEstimated Reading Time: 12 minsSF6 Circuit Breaker Construction, Types, Working and Uses electricaltechnology.org/2021/08/sf6 sulphur hexaflouride circuit breaker.htmlSulphur Hexafluoride or SF6 circuit breaker is a type of circuit breaker that uses pressurized SF6 gas to extinguish the arc. It is a dielectric gas having superior insulating and arc quenching properties far better than air or oil. It is used for arc quenching in high voltage circuit breakers up to 800 kV in power stations, electrical grids

High voltage DC circuit breaker HVDC circuit breakers are difficult to build because of arcing : under AC the voltage inverts, and in doing so crosses zero volts, dozens of times a second. An AC arc will "self extinguish" at one of these zero crossing points, because there cannot be an arc where there is no potential difference.

72.5kV Gas Insulated Circuit Breaker(SF6) CB General: Circuit breaker (CB) has been around for almost as long as industrial electrical power usage. They react automatically to fluctuations in electrical current, and trip to protect a circuit from damage from overloading or short circuiting. Modern SF6 type circuit breakers use compressed gas to interrupt current flow and are common in electrical power substations.
sulfur hexafluoride transformer toshiba guide
Arc Extinction. When the current carrying contacts of the circuit breaker are moved apart, an arc is formed, which insist for a short period after the separation of contacts. This arc is dangerous on account of the energy generated in it in the form of heat which may result in explosive force. The circuit breaker should be capable of extinguishing the arc without causing any disturbances to the equipment or danger to the personnel.
