摘要

根据电场和温度场的相似性

提出了用于计算复合介质地下电缆群稳态温度场的模拟热荷法。文中将电缆等效为缆芯和外护两层结构

借鉴静电场计算中复合介质交界面两侧介质的不同而用单一介质代替时的方法

根据束缚电荷引入"束缚热荷"的概念。认为在土壤和外护两种介质的分界面上有"束缚热荷"

在不同介质区域中布置模拟热荷来等效缆芯表面的热荷分布及不同介质分界面上的"束缚热荷"的作用。根据场的唯一性原理

用模拟热荷法计算土壤直埋下的电缆的复合介质稳态温度场

得出温度场图及热荷热量分布图。建立等效处理后的模拟电缆的试验模型进行试验研究

以及ANSYS有限元仿真计算。将模拟热荷法计算结果与试验结果和仿真结果进行对比

验证了模拟热荷法计算复合介质温度场的可行性。

Abstract

Base on the similarity of electric field and temperature field

the heat charge simulation method was given to calculate the composite dielectric steady temperature field for underground cables. In this paper

the cable was equivalent to two layers. Using the calculation method of composite dielectric electrostatic field for reference

we introduce the concept of bound heat charge according to the bound charge. Based on uniqueness principle of field

steady temperature of buried cable was calculated by heat charge simulation method. The graphs of temperature field and heat quantity were given. The test and finite element method（FEM） simulation have proved that heat charge simulation method is effective to calculate the steady temperature field of underground cables.
