20.500.12556/RUL-158822 Optimizacija in poenostavitev indikatorske vzmeti talilnega vložka Optimisation and simplification of fuse link indicator springs Indikatorska vzmet talilnega vložka služi indikaciji pregoretja talilnega elementa, ko se ta preobremeni. Indikatorska vzmet je ključni element indikacije, saj poleg samostojne indikacije to prikaže tudi v sodelovanju z mikrostikalom, ki omogoča daljinsko indikacijo. V podjetju se uporablja več tipov indikatorskih vzmeti. V delu smo najprej določili obratovalne pogoje, ki jih določa mikrostikalo. Na podlagi teh smo preverili delovanje indikatorskih vzmeti fizično kot numerično v programu Comsol Multiphysics. Na koncu smo primerjali rezultate simulacij in izmerjenih vrednosti. Spoznali smo, da geometrija uporabljenih vzorcev močno vpliva na rezultate in da smo se z numeričnimi simulacijami približali realnim razmeram. The indicator spring of a fuse link serves as an indication of the fuse element's burnout when it is overloaded. The indicator spring is a key element of the indication, as it shows this not only independently but also in cooperation with a microswitch, which enables remote indication. Several types of indicator springs are used in the company. In this work, we first determined the operating conditions, which are determined by the microswitch. Based on these, we verified the operation of the indicator springs both physically and also numerically by means of the program Comsol Multiphysics. Finally, we compared the results of the simulations with the measured values. We found that the geometry of the samples used has a strong influence on the results and that we were able to approximate close to real conditions with numerical simulations. indikatorska vzmet talilni vložek mikrostikalo obratovalni pogoji Weibullova porazdelitev Comsol Multiphysics indicator spring fuse link microswitch operating conditions Weibull distribution Comsol Multiphysics true false false [L.
