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。
Aiming at the selection of reference temperature in thermal fault infrared cruise detection of high voltage transmission line, the heat conduction process on the line is analyzed. According to the quasi one dimensional steady state thermal conduction model, the approximate analytic solution of the differential thermal conduction equation is discussed. The numerical value of temperature distribution along the line Calculation method, given the reference temperature reference. The simulation results of the thermal resistance thermal imager coincide well with the numerical calculation. This paper provides a theoretical basis for the thermal cruise infrared cruise detection of high voltage lines.
