| 摘 要： | 为深入研究GIS母线的损耗和发热问题,在综合考虑集肤效应、涡流损耗、电导率温度效应、气体流动、重力等多种因素影响的基础上,运用有限元方法,建立了GIS母线损耗发热的电磁场与流场求解模型。计算分析了该类母线的热源和温度分布规律,并与实测数据进行了比较。结果表明:GIS母线电流和损耗密度的分布都体现出集肤效应。当母线水平放置时,其导体与金属外壳的温度分布呈上高下低规律。对于水平放置的单相GIS母线,其温度分布左右对称,其内部环状空间气体对流作用较强,等温线呈弯曲的S型分布,同一圆周上温度分布并不均匀。而对于水平放置的三相GIS母线,其上方导体附近的气体等温线分布也呈现较为明显的S状弯曲,而位于下方导体周围的气体,其等温线扭曲程度相对较小。 |
