  • SF6 Circuit Breaker Types, Working Principles

    Feb 20, 2021SF6 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.. Sulfur hexafluoride gas has strong electronegativity and insulating properties, making them a better option than air and oil circuit breakers.

    The first generation of SF6 circuit breakers was the lower voltage classes of 72kV and 145kV. As SF6 breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing SF6 as the line-to ground dielectric insulation.powergrid
