Abstract

In order to obtain the temperature distribution of the internal conductor under the GIS overheating defect

3-D multi-physics coupling model was established to analyze the electromagnetic field

temperature field and gasflow field of 252 k V three-phase sub-aspect bus in GIS. The power loss of the GIS was calculated by Ansys Maxwell3 D

and temperature distribution was obtained by Ansys Fluent for heat flow coupling calculation. After modifyingthe simulation model parameters based on the test data of the surface temperature distribution of the shell

the simu-lation data of the surface temperature distribution of the shell and the internal conductor are in good agreement withthe test data. Finally

the applicability of the model was verified by the test data under different working conditions

and it lays the foundation for obtaining the temperature rise of the internal conductor for the known temperature riseof the shell

and it has important engineering application value.
