Abstract:V diplomskem delu je obravnavana NV talilna varovalka, ki se zaradi svojih ugodnih lastnosti še vedno uporablja za zaščito različnih vrst tokokrogov. V programu Vector fields Opera smo z metodo končnih elementov računali tokovne in toplotne razmere 3D modela NV talilne varovalke. S tranzientnim in statičnim izračunom sta analizirana toplotno in tokovno polje v različnih primerih. Statično toplotno in tokovno polje je izračunano za dve različni geometriji, dve vrsti uporabljenih materialov in pri različnih tokovih. Tranzientni izračun pa je narejen za analizo prehoda toplote v določenih časovnih korakih, za dva različna materiala in dva tokova. Z izračuni in grafičnim prikazom rezultatov smo dobili predstavo o dogajanju znotraj NV talilne varovalke v različnih pogojih.

Title:CALCULATION OF DISTRIBUTION OF CURRENT, JOULE LOSS AND TEMPERATURE IN THE NV ELEMENT OF THE FUSE
Abstract:This diploma discuss NV melting fuse which is still used for protection of various types of circuits due to its good properties. Using the finite element method with the software Vector Fields Opera we count thermal and current conditions in 3D model of NV melting fuses. The transient and static calculations are made to analyse thermal and electrical current field for different cases. Static thermal and static electrical current field calculations are made for two different geometry, two types of materials and for different current values. Transient calculations are made for heat transfer analysis in certain time intervals for two different materials and two different current rate. The calculations and graphical visualization of the results bring us feeling of happening within NV melting fuses in different conditions.
Keywords:Melting fuse, finite element method, electrical current field, thermal field
