Abstract

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.
