Abstract
This work aims to detect the discharge products and study the decomposition characteristics of C <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">5</sub> F <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">10</sub> O/N <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> gas mixture under pulsed discharge. Discharge tests are carried out on three kinds of gas mixtures with different contents of C <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">5</sub> F <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">10</sub> O (3.3%, 10%, and 30%). Electron attachment mass spectrometry (MS) is proposed to detect discharge products after negative ionization, and the results are compared with that in gas chromatography (GC) MS. The discharge products are detected and the formation pathways of the main decomposition products are deduced. The results show that the densities of some products increase with the number of discharge pulses. There are differences on the types of products and the cumulative effect of discharge in the three kinds of gas mixtures. Furthermore, these discharge products are able to characterize the discharge accumulation effects in power switchgear, such as insulation degradation.
