Method of Detecting Concentration of SF6 in GIS by Absorption of Infrared Laser
In order to realize precise and real-time detection of SF6 in gas-insulated switchgear(GIS), infrared laser absorption is studied and analyzed. Based on the strong absorption characteristics of SF6 at infraed wavelength(10.55 μm), the relation of SF6 concentration and its absorption characteristics is studied at this wavelength, and the relation curve is given. This method provides a theory foundation for quantification detection of SF6 in GIS.
