摘要
根据土壤直埋电缆的温度场特性,利用有限元法对热场进行剖分和计算,经过迭代计算出有土壤直埋电缆的载流量。通过多张图表,分析了影响土壤直埋电缆载流量的各个因素以及各因素对载流量的影响规律。
Finite element method is applied to solve the field with the temperature field characteristic, then the ampacity of buried cables is received after iterative computation. The ampacity reduction factors and the change rules for buried cables is presented through several graph tables.
