Özet

© 2023 Istanbul University. All rights reserved.The main goal of the present study is to carry out one-way coupled computations of electromagnetics and heat transfer for a simplified version of a switchgear and to reveal the applicability of the computational approach. In our computation, we introduce the joule losses that we obtain from the electromagnetic computations to a thermal solver as heat load. In order to reach the goal, we compare the temperature values that we obtained at eight different measurement points by performing computations and experimental measurements. In general, the distributions of the obtained temperature values are quite similar. The notable difference in the mean values of the obtained temperatures might result from limitations of one-way coupled approach where we have to neglect temperature dependency of the electrical properties during the electromagnetic computations.
