【 摘 要 】

The temperature in gas insulated bus bars are outcomes of coupled multiphysics field, such as thermal field, fluid field and eddy current field in which skin effect of current plays a considerable role. In this paper, the 3D model of GIS bus bar is established, and the skin effect of current is considered by further fine grids in the calculation to reach accurate loss value. Finite element method and fluid analysis are used to predict the distribution of temperature field of three-phase GIS bus bar.
