On-line Monitoring Technology of SF6 Decomposition Gas Based on Infrared and Ultraviolet Spectrum Analysis
Under the influence of spectroscopy,H2S products evaporate quickly,with a very obvious volatilization behavior.Based on spectral effects,it is difficult to accurately analyze the content of H2S products in SF6 decomposition gas.Therefore,an SF6 decomposition gas online monitoring technology based on infrared and ultraviolet spectroscopy analysis is studied.By connecting the infrared measurement unit,ultraviolet measurement unit,and multi-channel spectral pulse amplitude analyzer together,and using gas separation characteristic functions and adsorption isotherms,the content of H2S component in SF6 decomposition gas is accurately an-alyzed.Experimental results show that by using this method,the difference between the detection result of H2S gas products and that of the actual gas is always zero,achieving an accurate measurement for H2S component in SF6 decomposition gas.
