Abstract: With the intensification of global climate change, extreme weather events are becoming more frequent, and the thermodynamic performance and fatigue life of high-voltage transmission lines in high-temperature and high-humidity environments are increasingly drawing attention.High-temperature and high-humidity conditions have a complex impact on the thermal stress and material fatigue of transmission lines, potentially reducing the reliability and service life of the power grid.To address this issue, this paper proposes a thermodynamic analysis-based model for calculating thermal stress and predicting fatigue life of high-voltage transmission lines under high-temperature and high-humidity conditions.The study first provides a detailed analysis of the thermal stress in transmission lines under high-temperature and high-humidity conditions, revealing the impact of temperature and humidity variations on the thermal expansion and deformation of the lines.Subsequently, combining material fatigue theory, the paper establishes a fatigue life prediction model for the lines, quantifying the accumulation process of fatigue damage under the influence of thermal stress.Through this theoretical model, the paper aims to provide a scientific basis for the design, evaluation, and maintenance of high-voltage transmission lines in harsh environments, ensuring the stability and safety of the power system.
