摘要
通过检测SF_(6)分解组分可有效评估电气设备设备运行状态,进而保障设备的安全稳定运行。基于第一性原理提出Pt掺杂HfSe_(2)(Pt-HfSe_(2))检测SO_(2)和SOF_(2),研究Pt-HfSe_(2)对两种气体组分的吸附和传感机理,探究其作为电阻型气体传感器评估SF_(6)电气设备运行状态的应用潜力。结果表明,Pt-HfSe_(2)对SO_(2)的吸附性能强于对SOF_(2)的,同时,两种气体在Pt-HfSe_(2)表面具有较好的脱吸附性能,能够保证该传感材料的重复使用。Pt-HfSe_(2)具备开发为新型SO_(2)和SOF_(2)气体传感器件的条件,可用于评估SF_(6)电气设备的运行状态,为研究HfSe_(2)基气体传感器提供了理论支持,为新型纳米传感器件应用于电力设备故障诊断提供新思路。
By detecting SF_(6)decomposition components,the operating state of the equipment can be effectively evaluated,and the safe and stable operation of the equipment can be guaranteed.Based on the first principles,Pt-HfSe_(2)is proposed to detect SO_(2)and SOF_(2),and the adsorption and sensing mechanism of PT-HFSE_(2)on the two gas components is studied,so as to explore its application potential as a resistive gas sensor to evaluate the operating status of SF_(6)electrical equipment.The results show that the adsorption performance of Pt-HfSe_(2)on SO_(2)is stronger than that of SOF_(2),and the two gases have better desorption performance on the surface of Pt-HfSe_(2),which can ensure the reuse of the sensor material.Pt-HfSe_(2)has the conditions to be developed as new SO_(2)and SOF_(2)gas sensors,which can be used to evaluate the operating status of SF_(6)electrical equipment,providing theoretical support for the research of HFSE_(2)-based gas sensors,and providing a new idea for the application of new nano-sensor components to the fault diagnosis of power equipment.
