Comparison Between Vacuum and Sulfr hexafluoride Circuit Breaker

Aug 29, 2018 · Because of the high conductivity of the arc in the sf6 gas gas, the arc energy is low. (arc voltage is between 150 and 200V.) Because of the very low voltage across the metal vapour arc, energy is very low. (Arc voltage is between 50 and 100V.) Contact Erosion: Due to the low energy the contact erosion is small.Get price

Sulfur hexafluoride circuit breaker - Wikipedia

Sulfur hexafluoride is generally used in present high-voltage circuit breakers at rated voltage higher than 52 kV. Into the 1980s, the pressure necessary to blast the arc was generated mostly by gas heating using arc energy. It is now possible to use low-energy spring-loaded mechanisms to drive high-voltage circuit breakers up to 800 kV.Get price
