20.500.12556/DKUM-77303 Zamenjava nemagnetnega materiala pokrova nv talilne varovalke z magnetnim materialom diplomsko delo Replacement of non magnetic materials with magnetic materials on nh fuse link Diplomsko delo opisuje preizkuse varovalk tipa NV po predpisanem standardu IEC 60296. Predstavljeni so vsi preizkusi danega standarda, podrobneje opisani pa so trije, ki so se tudi opravili. Opisani so vsi tipi varovalk, sestava ter prednosti in slabosti pa so predstavljene za obravnavane varovalke tipa NV1C. Opravil sem test merjenja temperature in izgubnih moči, test za IN tok in If tok. Vsi rezultati so bili pozitivni in opazil sem razliko med varovalkami z železnim pokrovom in varovalkami z aluminijastim pokrovom. Predstavljena je tudi simulacija, ki je bila izvedena v programu Comsol Multiphysics. Podane so izgubne moči ter razlike pri segrevanju varovalk. Rezultati so primerljivi z realnimi. The diploma thesis describes the tests of NV type fuses according to the prescribed standard IEC 60296. All tests of a given standard are presented, and three of them are described in more detail, which were also performed. All types of fuses are described, and the composition, advantages and disadvantages are presented for the considered fuse type NV. I did a temperature measurement test, an Inf current test and an If current test. All results were positive and I noticed a difference between fuses with an magnetic cover (iron) and fuses with an non magnetic cover (aluminum). A simulation performed in the Comsol Multiphysics program is also presented. Power dissipation and differences in fuse heating are given. The results are comparable to the real ones.
