A 3-D electromagnetic-thermal-mechanical coupling finite element model of a gas-insulated bus plug-in connector is proposed in this paper with a subsequent analysis for the contact fatigue mechanism. Special attention has been paid to the contact degradation mechanism under normal cyclic operation conditions, which is important for the optimal designing and condition monitoring of the equipment. The...
Contact resistance of Gas insulated switchgear (GIS) bus conductor would increase and overheat itself in long-term operation. This paper established mathematical model to figure out temperature distribution of 4kA single-phase GIS bus. Power loss in electromagnetic field was calculated and indirectly coupled to temperature and flow field. Calculation result showed that the temperature distribution...
