H2S and SO2 are important characteristic gases reflecting latent insulated defects in gas insulated switchgear (GIS).The detection of the H2S and SO2 is of great significance to diagnose and assess the operating status of GIS. In this paper, the single-walled carbon nanotubes (SWCNTs) are modified by hydroxyl and carboxyl, respectively. The gas sensing response of the modified SWCNTs to H2S and SO2 are studied. The results show that the sensitivity of SWCNTs modified by carboxyl is higher than that of SWCNTs modified by hydroxyl to H2S, the same for SO2.
