Health and environmental dangers of insulating gas-filled switchgear

While SF 6 is regarded as a non-toxic gas, experts agree that it can displace oxygen in the lungs, and therefore cause asphyxia if too much is inhaled. SF 6 gas is approximately five times heavier than air and, if released or leaked in sufficient quantity, tends to accumulate, initially in low-lying areas where there is no natural ventilation, and may cause asphyxiation [12].Get price

Sulfur hexafluoride circuit breaker - Wikipedia

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 gas to cool and quench the arc on opening a circuit. Advantages over other media include lower operating noise and no emission of hot gases, and relatively low maintenance. Developed in the 1950s and onward, gaz sf6 circuit breakers are widGet price
