摘要:
High-voltage gas-insulated switchgear (GIS) experiences insulation aging and related issues during prolonged operation, which significantly reduces the stability and safety of energy power equipment. Therefore, real-time monitoring and assessment of the insulation condition of these devices is essential. This study, based on first-principles calculations, reveals the gas-sensitive properties of decomposition gases of SF 6 and its five insulation defects on the surfaces of AlN and Pt 2 –AlN at the quantum level by calculating the electronic den...
