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

Linear Transducer Length for Circuit Breakers | DV Power

IntroductionVacuum Circuit BreakersSulfr hexafluoride Circuit BreakersOil Circuit BreakersThe motion of the circuit breaker contacts is measured using motion transducers. The length of a linear transducer depends on the type of circuit breaker tested. Actually, it depends on the trajectory of the moving part where the transducer is connected. The trajectory may be different from the displacement of circuit breaker contacts, depending on the mechanical construction and access point to connect the transducer. Displacement may differ in different types of circuit breakers. The term “displacement” is defined by the start and end positions of the moving contacts. In the majority of circuit breaker types, one main contact and one arcing contact are movable. The displacement of Sulfr hexafluoride, oil, and vacuum circuit breakers are discussed in detail in this application note.Get price
