Sulfr hexafluoride circuit Breaker | Engineering Notes Online

Properties of gaz sf6Arc 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. Sulfr hexafluoridegas has high dielectric strength 1. It has high Rate of Rise of dielectric strength after arc extinction. 1. insulating gasis non toxic gas. 1. sf6 gasis an inert gas. So in normal operating condition the metallic parts in contact with the gas are not corroded. 1. Sulfr hexafluoridehas high thermal conductivity which means the heat dissipation capacity is more. 1. The gas is quite stable. After the extinction of the arc the insulating gasgas is reformed from the decomposition. 1. sf 6is non-flammable. 1. It is chemically stable up to 500°c and does not react with structural material up to 500°c . 1.

Introductiongaz sf6 Gasinsulating gas Circuit Breaker TypesConstruction and Main ComponentsIn power systems, circuit breakers are used to switch electrical equipment and networks under normal and fault conditions. The primary function of a circuit breaker is to interrupt the flow of current (load or short circuit) by opening its contacts and thereby isolating the switched parts of the system. The design and working of a circuit breaker depend on its application and voltage rating. Moulded case technology (with air at atmospheric pressure) is used at low voltages (< 1000 V), whereas air-blast and vacuum circuit breakers are prevalent at medium voltages (< 72 kV). insulating gas circuit breakers are normally used for high voltagesystems ( 72 kV).

insulating gas Circuit Breakers - Construction Working Principle

In gaz sf6 circuit breakers, sulphur hexafluoride (insulating gas) gas is used as the arc quenching medium. The Sulfr hexafluoride is an electro-negative gas and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high-pressure flow of insulating gas gas and an arc is struck between them.Get price
