Get PriceMany of the SF 6 circuit breakers were added to existing substations. The replacement of a single circuit breaker usually doesn’t warrant the close examination of the station service. Existing oil circuit breakers have, however, minimal heating requirements and, as a whole, their AC load is not significant.
Get PriceSF6 gas leakage - SF6 breakers (live and dead tank) typically have a combination of static seals (O-rings and gaskets) as well as dynamic seal assemblies where the mechanism energy is transferred through to the interrupter assembly. Over time, seals degrade due to environmental conditions and exposure and will need to be replaced.
Get PriceFaulted SF6 Gas Circuit Breaker. In the occurrence of arc discharges, spark discharges and corona discharges, SF6 can react with very little water, air, electrode and solid insulated material. Producing a byproduct include carbon tetrafluoride (CF4), thionyl sulfide (SOF2), sulfuryl fluoride (SO2F2), and sulfur dioxide (SO2), along with solid byproduct including aluminum fluoride, tungsten fluoride.
Get PriceSF 6 gas, used as a dielectric medium in circuit breakers and switchgear, has a global warming potential 24 000 times greater than CO 2 and some of its by-products were used as chemical weapons in World War I.
