Ultraviolet differential spectroscopy quantitative analysis of SF6 decomposition component SO2
IET Science, Measurement & Technology(2018)
摘要
SO2 is a symbolic gas that can indicate the insulation status of SF6 insulation electrical equipment. Its accurate quantitative measurement is of the great significance for the judgement of the type and severity of faults inside the insulation equipment. For this reason, a detection system of trace SO2 based on ultraviolet (UV) spectrometry was presented. The measured UV absorption spectra of SO2 ...
