Abstract EN
H2S and SO2 are important gas components of decomposed SF6 of partial discharge generated by insulation defects in gas-insulated switchgear (GIS).
Therefore, H2S and SO2 detection is important in the state evaluation and fault diagnosis of GIS.
In this study, dielectric barrier discharge was used to generate CF4 plasma and modify multiwalled carbon nanotubes (MWNTs).
The nanotubes were plasma-treated at optimum discharge conditions under different treatment times (0.5, 1, 2, 5, 8, 10, and 12 min).
Pristine and treated MWNTs were used as gas sensors to detect H2S and SO2.
The effects of treatment time on gas sensitivity were analyzed.
Results showed that the sensitivity, response, and recovery time of modified MWNTs to H2S were improved, but the recovery time of SO2 was almost unchanged.
At 10 min treatment time, the MWNTs showed good stability and reproducibility with better gas sensing properties compared with the other nanotubes.
