A numerical procedure employing the finite element technique is developed for the computation of the coupled magnetothermal field in three-phase gas insulated cables. The finite element formulation of both the electromagnetic and temperature field problems, the iterative procedure and the effective thermal conductivity of the insulation gas needed for the solution of the problem are presented here. Calculations made with the proposed method are presented in Part 2.
Übersicht
Es wird ein auf der Methode der finiten Elemente basierendes numerisches Verfahren zur Berechnung des gekoppelten magnetisch-thermischen Feldes dreiphasiger gasisolierter Kabel entwickelt. Hierzu werden der Lösungsansatz mit finiten Elementen für das elektromagnetische Feld und das Temperaturfeld, das Iterationsverfahren und die zur Lösung des Problems benötigte effektive thermische Leiftähigkeit des Isoliergases angegeben. Berechnungsergebnisse mit der vorgeschlagenen Methode werden in Teil 2 vorgestellt.
