摘　　要：针对直埋方式的三芯交联聚乙烯(XLPE)电力电缆利用有限元法能任意布置结点和网格的特点,建立了地下电缆温度场计算模型,阐述了其计算原理。通过实例计算结果与实验数据对比表明,采用有限元法分析电力电缆载流量和温度场切实可行,且计算精确度高。Aiming at the directly buried three - core XLPE cable, the calculation model of temperature field for underground cable is established, of which the theory is expounded, taking advantage of the characteristics of finite element method which is able to free arrange node and grid. The comparison between calculation of examples and data of experiments shows that it is feasible to analyze ampacity and temperature field for electric power cable based on finite element method with a high accuracy of calculation.
