THE INFLUENCE OF BUSBARS CONNECTION ON FUSELINK TEMPERATURE AT FAST FUSES

The paper, based on three-dimensional thermal modelling and simulation finite element method software package, presents a comparison between the thermal behaviour of a fast fuse without busbar terminals and the one with these busbars mounted on it. The maximum fuselink temperature is lower in the second case when the thermal model had taken into consideration the busbar connections, actually, the real situation. Also, a thermal analysis for different type of load variations has been done in both cases of the fast fuse geometry with and without busbar terminals
