摘要/Abstract

摘要： 通过检测SF₆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HfSe₂(Pt-HfSe₂)检测SO₂和SOF₂,研究Pt-HfSe₂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SF₆电气设备运行状态的应用潜力。结果表明,Pt-HfSe₂对SO₂的吸附性能强于对SOF₂的,同时,两种气体在Pt-HfSe₂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-HfSe₂具备开发为新型SO₂和SOF₂气体传感器件的条件,可用于评估SF₆电气设备的运行状态,为研究HfSe₂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。

Abstract: :By detecting SF₆ 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-HfSe₂ is proposed to detect SO₂and SOF₂, and the adsorption and sensing mechanism of PT-HFSE₂ 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 SF₆electrical equipment. The results show that the adsorption performance of Pt-HfSe₂ on SO₂ is stronger than that of SOF₂, and the two gases have better desorption performance on the surface of Pt-HfSe₂, which can ensure the reuse of the sensor material. Pt-HfSe₂ has the conditions to be developed as new SO₂ and SOF₂ gas sensors, which can be used to evaluate the operating status of SF₆ electrical equipment, providing theoretical support for the research of HFSE₂-based gas sensors, and providing a new idea for the application of new nano-sensor components to the fault diagnosis of power equipment.
