| 摘 要： | 针对高压输电线路热故障红外巡航检测中参考温度的选择问题，分析了线路上的热传导过程，根据准一维稳态导热模型，讨论了导热微分方程的近似解析解，建立了温度沿线分布的数值计算方法，给出了参考温度的选择基准。通电电阻丝热像仪测温的模拟实验结果与数值计算结论吻合较好，本文为高压线路热故障红外巡航检测提供了理论依据。

| Abstract: | In this paper,the heat conduction of high voltage transmission is discussed for selecting temperature of reference in infrared aerial detection of defeects. According to one dimensional model of steady state, heat conduction equation is worked out, its approximate analytic solution and numerical solution are discussed.The temperature of reference is given theoretically.Experiments result of us and others is in agreement with the numerical compunction result of us. |
