Abstract：Overheat failure simulation tests are carried out to study the formation, developing process and the results of overheat failures in gas-insulated bus (GIB) bar. With the constraints of prototype tests, scale model is used in the physical simulation tests. Scaling criterions of the coupled eddy current-fluid-thermal field are derived and simplified by analyzing the similarity of temperature rise in GIB contacts. Scale model of GIB is designed and produced with the given geometric conditions, physical conditions and boundary conditions. Tests and numerical calculations verify the scale model. Under the poor contact, the temperature rise simulation test and the overheating failure simulation test are carried out to analyze the physical processes of the overheating and the variations of temperature on contacts.
