Zhang X, Zhang J, Jia Y, Xiao P, Tang J - Sensors (Basel) (2012)

Bottom Line: The detection of partial discharge through analysis of SF(6) gas components in gas-insulated switchgear, is significant for the diagnosis and assessment of the operating state of power equipment.The present study proposes the use of a TiO(2) nanotube array sensor for detecting the SF(6) decomposition product SO(2), and the application of the anodic oxidation method for the directional growth of highly ordered TiO(2) nanotube arrays.The sensor response of 10-50 ppm SO(2) gas is tested, and the sensitive response mechanism is discussed.

ABSTRACT
The detection of partial discharge through analysis of SF(6) gas components in gas-insulated switchgear, is significant for the diagnosis and assessment of the operating state of power equipment. The present study proposes the use of a TiO(2) nanotube array sensor for detecting the SF(6) decomposition product SO(2), and the application of the anodic oxidation method for the directional growth of highly ordered TiO(2) nanotube arrays. The sensor response of 10-50 ppm SO(2) gas is tested, and the sensitive response mechanism is discussed. The test results show that the TiO(2) nanotube sensor array has good response to SO(2) gas, and by ultraviolet radiation, the sensor can remove attached components very efficiently, shorten recovery time, reduce chemical poisoning, and prolong the life of the components.
