基于电—热场耦合分析的高压大容量直流XLPE海缆绝缘结构研究
Gaoya dianqi, 2022 随着交联聚乙烯直流海缆向着高电压、大容量的方向发展，其在工程应用中也遇到了温度和电场两方面的挑战。文中结合±160 kV XLPE直流海缆建立了XLPE海缆的电场仿真模型和热路模型，对更高电压等级的XLPE直流海缆的结构特点进行了探讨。通过仿真发现，直流海缆绝缘层的厚度同时影响海缆的温度和场强分布，在对高电压、大容量海缆设计时需要综合考虑绝缘材料能承受的最大场强和最高温度，选取合适的绝缘层厚度。同时，通过仿真对比铜、铝导体电缆对电场、温度的影响发现，铜导体电缆运行温度较低，有利于电缆稳定运行 ...

252 kV GIS隔离开关温度场仿真及触头温度的预测方法研究
Gaoya dianqi, 2023 为了实现对气体绝缘开关GIS(gas insulator switchgear)触头温升的预测，文中建立了252 kV三相分箱型GIS隔离开关的三维电磁—传热—流场的多场耦合模型并采用有限元方法进行了求解。通过一段电阻率可变导体来模拟隔离开关触头存在接触电阻的情况，首先通过电磁场计算出各部分损耗，再将损耗作为热源带入传热-流场中，最后计算得到GIS的温度分布。对环境温度在-10～30℃、载流量在1 000～3 150 A、接触电阻在0～100μΩ的条件下，基于该模型计算出了不同情况下GIS的温度场分布 ...
