农网低压线路选择农用直埋电缆可以实现造价低、线损小、安全、可靠的目的。
The goal of lower cost and lower line lost and safety and reliability can be achieved by choosing rural direct-buried cable in rural LV line.
利用有限元法对有外部热源的直埋电缆区域进行剖分，计算了给定电缆负荷的温度场。
Finite element method (FEM) was used to partition the area of buried cables with outer heat sources and calculate the temperature field with given cable load.
特别是对于直埋电缆，如果不能快速准确地确定故障点位置，故障的排除就会花费大量的时间、资金和人力。
Especially for the buried cable, if the fault point can't be located quickly and precisely, it would expend a lot of time, funds and manpower.
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。
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.
