Sf6 circuit breaker animation. Main and arc contacts identification alo. Single interruption sf6 circuit breaker is suitable for 245kv systems. Circuit breaker field from the first breaker to use sf6 gas as an arc extin guishing medium in the 1980s to the newest breakers described in this article rated at 24 000 a naturally cooled and 38 000 a with forced air cooling and able to handle short circuit breaking currents of up to 200 ka. The sulphur hexafluoride gas sf6 is an electronegative gas and has a strong tendency to absorb free electrons.

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. In this video sf6 circuit breaker is discussed with respect to following points. Sf6 is also a suitable medium for metal clad high voltage substation called gas insulated substation. The contacts of the breaker are opened in a high pressure flow sulphur hexafluoride sf6 gas and an arc is struck between them.

The sf 6 circuit breaker is mainly. The circuit breaker in which the contacts open and close in the sf6 medium is called the sf6 circuit breaker. In this video you can learn about types of sf6 circuit breakers constructions of sf6 circuit breakers and working of sf6 circuit breakers with highly animat. These circuit breakers are available for all levels of voltages.

In an sf6 circuit breaker sulphur hexafluoride gas is used as the arc quenching medium. One could also witness what happens when a circuit fault occurs and.
