摘要
为了实现高压变电站室内SF_6气体浓度的精确实时检测,对红外激光吸收方法用于SF_6检测进行了研究和分析。根据SF_6气体在红外波段(10.55μm)的强吸收特性,研究了在该波段下SF_6吸收特性和其浓度之间的关系,并得出了二者之间的关系曲线。该方法为高压变电站室内SF_6气体的定量检测提供了理论基础。
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.
