Odpowiedź na obecność H2S lub SO2 czujników SWCNT modyfikowanych hydroxylem luv carboxylem
Języki publikacji
Abstrakty
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.
Przedstawiono metodę detekcji H2S iSO2 jako możliwość oceny stanu izolacji przełączników gazowych GIS. Jako czujnik wykorzystano nanorurki węglowe SWCNTs modyfikowane przez wodorotlenki hydroxyl i carboxyl.
