Abstract

This paper presents a new magneto-thermal finite element analysis for predicting the temperature rise of the EHV GIS busbar. Joule's heat due to current flowing in the main conductor and the heat due to the induced eddy current in the tank are calculated by the magnetic field analysis. And these heats are used as the input data to predict the temperature rise for the thermal analysis. However, it is not easy to apply the heat-transfer coefficients on the boundaries for the thermal analysis. In this paper, the heat-transfer coefficients on the boundaries are analytically calculated by applying the Nusselt number considering material constant and model geometry for the natural convection. The temperature distribution in the busbar by coupled magneto-thermal finite element analysis shows good agreement with the experimental data.
