摘要: 户外安装的气体绝缘母线运行状态因受环境因素的影响较大，已有的户内设备计算模型并不能较好地适用于它。本文针对户外气体绝缘母线，建立气体绝缘母线三维涡流场分析模型计算母线各部分原件的功率损耗，并将其作为热载荷输入流体场以及温度场有限元分析模型，并加入太阳辐射模型和风速模型，计算出了母线温度场分布。结果表明，日照和风速影响着外壳的温度场分布，在进行母线温度场分析时应予以考虑。本文运用的太阳辐射模型和风速模型对于户外设备温升计算具有实际意义。
Abstract: The running state of outdoor gas insulated buses is greatly affected by environmental factors, so the calculation model used for indoor equipment cannot be well applied. In this paper, a three- dimensional eddy current field analysis model is established for outdoor gas insulated buses to calculate the power loss of each part of the bus, and it is taken as a finite element analysis model for thermal load input fluid field and temperature field, and solar radiation model and wind speed model are added to calculate the temperature field distribution of the bus. The results show that sunshine and wind speed affect the temperature field distribution of the shell, which should be taken into account when analyzing the temperature field of the bus. The solar radiation model and wind speed model used in this paper have practical significance to calculate the temperature rise of outdoor equipment.
