摘　　要：离相气体绝缘母线的温升和散热性能是影响其工作稳定性的重要因素之一。笔者先通过涡流场计算得到导体及外壳的焦耳热损耗,然后将其作为体积热源,通过间接耦合方法再计算出母线温度场分布,进而与实验数据进行对比,验证温度场计算结果的正确性,最后分析环境温度、气体压强以及不同负荷电流对母线温度场分布的影响。所得出的结论对离相气体绝缘母线散热设计具有参考价值。Temperature rise and heat dissipation performance is one of the most important factors influencing the operation status of isolated Gas Insulated Bus （GIB）. Joule power losses of the conductor and tank are firstly calculated by eddy current field analysis and are indirectly coupled into temperature field of isolated GIB as heat generation rate. Then the calculation results are verified by comparison with experimental data. At last, the calculation method is used to analysis how the temperature field of isolated GIB is influenced by ambient temperature, gas pressure and different load current. The analysis results can provide some advices and references for heat dissipation design of isolated GIB.
