Sulfur hexafluoride circuit breaker - Wikipedia

An SF 6 circuit breaker rated 115 kV, 1200 A installed at a hydroelectric generating station. Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. 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.Get price

sf 6 Circuit Breaker - your electrical guide

The sf6 gas gas is blown axially along the arc by the gas system of the breaker. The gas is made to flow from a high-pressure zone to a low-pressure zone through a nozzle. The nozzle is located such that the gas flows axially over the arc length. The heat is removed from the arc by axial convection and radial dissipation.Get price
