sf6 mixture Quantitative worries rule

17/01/2020Trace O2 significantly affects the diagnosis accuracy of decomposed components analysis method for spark discharge due to its direct participation in SF6 decomposition process. Therefore, spark discharge decomposition experiments were conducted under different proportions of SF6/O2 mixtures. The influence rules and mechanisms of φ(O2) on the content and characteristic ratio of SF6

Published: 23/02/2021Industrial Sources of SF6Leak Monitoring and ControlThe Chillcard Ng and Guardian NgReferences and Further ReadingThe long atmospheric lifetime of SF6 and the lack of natural decomposition routes for it mean that SF6 concentrations in the atmosphere have continued to rise. Concerns about its contribution to global warming and the lack of methods for removing it from the atmosphere led to an EU-wide ban on the use of SF6 in 2014, See more on edinburghsensorsAlternatives to SF6 in HV Circuit Breaker Insulation eprints.usq.edu.au/27073/1/Marland_2014.pdfPDF) is a synthetic gas extensively used in the high voltage (HV) electricity transmission and distribution industry.
