Abstract
Gas-insulated switchgear (GIS) using sulfur hexafluoride (SF6) as insulating medium has been widely utilized in electrical industry. However, SF6 gas will decompose into several components under partial discharge, like SO2, SOF2, and SO2F2. TiO2 nanomaterials were reported to have an excellent performance in the gas-sensitive fields. In this paper, we have proposed a new method of online monitoring to detect these products by nitrogen-doped TiO2 nanotubes sensor (N–TiO2 ) in order to easily evaluate the operating condition of GIS. We first set up the experimental platform for this work, and then separately discussed the gas-sensitive response characteristics of N–TiO2 to three by-products. Finally, repeatability of this gas sensor was measured. The results show that the N–TiO2 have a good repeatability as a gas sensor. The sensitivity of the N–TiO2 to SO2F2 is weakest. Compared to SO2F2, the N–TiO2 is more sensitive to both SO2 and SOF2, and better to SO2.
