Sulfr hexafluoride circuit Breaker | Engineering Notes Online

Properties of sf6 gasArc ExtinctionConstructionsulphur hexafluoride gas is prepared by burning coarsely crushed sulphur in fluorine gas.The sulphur hexafluoride gas possesses very good insulating properties and outstanding arc-quenching characteristics which make it an ideal medium for circuit interruption. 1. insulating gasgas has high dielectric strength 1. It has high Rate of Rise of dielectric strength after arc extinction. 1. sf6 gasis non toxic gas. 1. Sulfr hexafluorideis an inert gas. So in normal operating condition the metallic parts in contact with the gas are not corroded. 1. sf 6has high thermal conductivity which means the heat dissipation capacity is more. 1. The gas is quite stable. After the extinction of the arc the Sulfr hexafluoridegas is reformed from the decomposition. 1. Sulfr hexafluorideis non-flammable. 1. It is chemically stable up to 500°c and does not react with structural material up to 500°c . 1. It is strongly electronegative gas which means that free electrons are readily removed from a discharge by the formation of negative ions . 1. The thermal time cons...Get price
