Abstract: In this paper, the three-dimensional finite element model of a low
voltage and heavy current three-phase busbar bridge system is established. The
edge element is used to discretize the finite element equations of the
electromagnetic field. The main characteristics of magnetic flux density and
electromagnetic force in the system are obtained. Through the comparison
between calculation results and measured ones, the reliability of the
calculation is validated. The influence of the operating current, different
arrangements of three-phase busbars, space between each phase busbar and
frequency on electro-magnetic parameters, especially magnetic flux density and
electromagnetic force, are also studied.
Keywords: Low voltage, heavy current, three-phase busbar bridge, eddy current field, edge element
