SF6-Air Recovery wika

Jan 14, 2013Visual recovery after retinal detachment surgery is limited by the length of time that gas remains in the eye. C3F8 has a longer half-life than SF6 gas. The use of SF6 gas has increased, with the trend toward shortened duration of endotamponade as surgical techniques improve. Traditionally, air tamponade has not been utilized for retinal ...

  • Sulfur hexafluoride circuit breaker - Wikipedia

    Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6) gas to cool and quench the arc on opening a circuit. Advantages over other media include lower operating noise and no emission of hot gases, and relatively low maintenance.

  • What is SF6 Circuit Breaker? Construction, Working

    Jun 11, 2016Sulphur Hexafluoride (SF6) Circuit Breaker A circuit breaker in which SF 6 under pressure gas is used to extinguish the arc is called SF 6 circuit breaker. SF 6 (sulphur hexafluoride) gas has excellent dielectric, arc quenching, chemical and other physical properties which have proved its superiority over other arc quenching mediums such as oil or air. . The SF 6 circuit breaker is mainly

  • Vacuum interrupter - Wikipedia

    Since the arc is contained within the interrupter, switchgear using vacuum interrupters are very compact compared with switchgear using air, SF 6 or oil as arc-suppression medium. Vacuum interrupters can be used for circuit-breakers and load switches. Circuit-breaker vacuum interrupters are used primarily in the power sector in substation and power-generation facilities, and load-switching
