A Pt-Doped TiO(2) Nanotube Arrays Sensor for Detecting SF(6) Decomposition Products

The detection of partial discharge and analysis of SF(6) gas components in gas-insulated switchgear (GIS) is important for the diagnosis and operating state assessment of power equipment. The use of a Pt-doped TiO(2) nanotube arrays sensor for detecting sulfur hexafluoride (SF(6)) decomposition prod...

description The detection of partial discharge and analysis of SF(6) gas components in gas-insulated switchgear (GIS) is important for the diagnosis and operating state assessment of power equipment. The use of a Pt-doped TiO(2) nanotube arrays sensor for detecting sulfur hexafluoride (SF(6)) decomposition products is proposed in this paper. The electrochemical pulse deposition method is employed to prepare the sensor array. The sensor's response to the main characteristic gaseous decomposition products of SF(6) is evaluated. The gas sensing characteristic curves of the Pt-doped TiO(2) nanotube sensor and intrinsic TiO(2) nanotube arrays sensor are compared. The mechanism of the sensitive response is discussed. Test results showed that the Pt-doped nanoparticles not only change the gas sensing selectivity of the TiO(2) nanotube arrays sensor with respect to the main characteristic SF(6) decomposition products, but also reduce the operating temperature of the sensor.
