| 摘 要： | 针对地下电缆结构和敷设过程中影响地下电缆输送能力的问题,应采取有效的方法对电缆的载流量和温度场进行准确分析计算.根据传热学原理,提出用有限元方法分析给定电缆负荷载流量和地下电缆温度场分布较为适宜.将该方法与IEC标准进行对比,完全符合要求.

| Abstract: | In the running of underground cable,interception quantity is a significant parameter determining delivery value.In order to enhance the delivery value of underground cable,the interception quantity and temperature field should be accurately analyzed and calculated.On the basis of heat transfer principle,considering the cable structure and installation condition,this paper puts forward to analyze set interception quantity of cable charge and distribution of underground cable temperature field by finite element.This method is proved to meet the requirements after comparing with IEC standards. |
