چکیده
In this paper, Gas insulated Switchgear bus bar has been investigated using 3D coupled multiphysics finite element analysis. The coupled field analysis involved consecutive multi-physics interactions. The interaction is characterized as a two-way sequential electromagnetic-thermal field coupling. The temperature rise in the GIS bus bar is due to the Joule’s losses in the conductor and induced eddy current in the tank. The power losses in a bus bar configuration solved by magnetic field analysis are the input to the thermal analysis. The heat transfer calculation using the fluid analysis is done by considering the natural convection and the radiation from the tank to atmosphere. Consequently, temperature distributions by coupled field multi-physics have good agreement with result of temperature rise test.
