SF6 circuit breaker is an extinguisher that uses sulfur hexafluoride gas to cool and quench the arc. It is the type of circuit breaker used to protect electrical grids, power stations, and distribution systems.
What is an SF 6 Circuit Breaker An SF6 circuit breaker is a type of circuit breaker in which sulphur hexafluoride gas or SF 6 gas is used as the arc quinching medium, known as an SF6 circuit breaker. SF 6 gas has excellent insulating property and it has a high electronegativity.
SF6 circuit breakers utilize Sulphur Hexa Fluoride (SF6) gas as the surrounding insulating medium for extinguishing the arc established between the moving breaker contacts. It has many favourable characteristics that make it an ideal insulation candidate in modern high voltage switchgear:
The interrupter unit of sulphur hexafluoride (SF6) circuit breaker consists of fixed and moving contacts enclosed in a chamber. The chamber is called the arc interruption chamber which contains the SF6 gas. This chamber is connected to sulphur hexafluoride (SF6) gas reservoir.
A circuit breaker in which the contacts open and close in sulfur hexafluoride (SF6) gas is known as an SF6 circuit breaker. SF6 Circuit Breaker Where Do We Use Sulfur Hexafluoride Breaker? These circuit breakers are available for complete range of medium voltage and high voltage application up to 800 kV and above.
A circuit breaker in which SF6 under pressure gas is used to extinguish the arc is called SF6 circuit breaker. SF6 (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 SF6
SF6 gas circuit breakers are used at EHV and UHV level. The external designs available in EHV and UHV circuit breaker are mainly of live tank type and dead tank type as mentioned.
