摘　　要：动态增容需要精确的电缆热路模型特征参数。在详细介绍电缆结构的基础上,阐述电缆的热路模型。分析IEC法、热阻修正法、形状因子法3种用于计算电缆热路模型特征参数的主要方法的基本原理,研究它们的特点,指出热阻修正法、形状因子法是IEC法的有益补充。最后,探讨精确分析电缆热路模型特征参数方法的研究趋势。It is very important for dynamic capacity-increase to work out the characteristic parameters of cable thermal circuit model accurately. Cable structure was introduced in detail and cable thermal model was elaborated. Principles of IEC method,shape factor method and thermal resistant correction method,which are main approaches to calculate the characteristic parameters,were set forth and features of the methods were investigated. Then we pointed out that shape factor method and thermal resistant correction method are useful and necessary complementarities to IEC method. Finally,we discussed the research trend to compute the characteristic parameters precisely.
