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.

摘要

通过分析气体绝缘开关设备中的 SF6 气体成分来检测局部放电,对于诊断和评估电力设备的运行状态具有重要意义。本研究提出使用 TiO2 纳米管阵列传感器来检测 SF6 分解产物 SO2,并应用阳极氧化法来定向生长高度有序的 TiO2 纳米管阵列。测试了传感器对 10-50ppm SO2 气体的响应,并讨论了其敏感响应机制。测试结果表明,TiO2 纳米管传感器阵列对 SO2 气体具有良好的响应,并且通过紫外辐射,传感器可以非常有效地去除附着的组件,缩短恢复时间,减少化学中毒,延长组件的使用寿命。
