Abstract
As an excellent alternative gas for sulfur hexafluoride(SF6), heptafluoroisobutyronitrile(C4F7N) has received widespread attention. C4F7N gas mixture has the potential to be applied to gas-insulated electrical equipment due to its good insulation properties. Quick and easy quantification of the gas mixture and its decomposition products has great significance. In this paper, the infrared spectroscopy is used to detect the three decomposition products of hexafluoropropene(C3F6), carbon monoxide(CO), and carbonyl fluoride(COF2). Combining chemometrics, a partial least squares(PLS) analysis model of C4F7N and its decomposition products is established. Quantitative analysis of CO, C3F6 and C4F7N is achieved by infrared spectroscopy and chemometrics. The research provides new ideas for the decomposition products detection and future online monitoring of alternative gas-insulated equipment.
