Abstract:Pri razvoju nove generacije varovalčnega ločilnega stikala smo se odločili za uporabo 3D simulacij z metodo končnih elementov v programskem paketu Comsol Multiphysic. V omenjenem programu smo želeli izdelati simulacijski model, ki bi omogočal vnos dejanskega 3D modela izdelka, s katerim bi lahko računali temperaturne razmere, ki nastajajo na izdelku pri različnih obratovalnih pogojih. Pri tem smo naleteli na osrednji problem magistrskega dela, uporabe robnih pogojev za prenos toplote s prevajanjem, prestopom in sevanjem. Namen je izdelati simulacijski model varovalčnega ločilnega stikala za analizo dejanskih temperaturnih razmer, kot jih je mogoče izmeriti v elektrotehničnem laboratoriju na izdelku. Pozneje bi bil takšen model uporaben tudi pri izračunih ostalih elektrotehničnih izdelkov za potrebe določitve temperatur med obratovanjem. Z namenom simulacij temperature smo morali ugotoviti postopek, po katerem bi določili robne pogoje za prehajanja toplote glede na električne lastnosti izdelka. Izdelali smo simulacijski model in določili postopek uporabe robnih pogojev prehoda temperature. Primerjalno smo varovalčno ločilno stikalo pomerili tudi v elektrotehničnem laboratoriju ter izmerjene in izračunane podatke primerjali med seboj.

Title:Determination of the boundary conditions for calculating the temperature conditions using the finite element method on an example of a fuse switch disconnector
Abstract:In the development of the new generation of the fuse switch disconnector, we decided to use 3D simulations with the finite element method in the Comsol Multiphysics software package. By using this software package, we wanted to create a simulation model in which would be possible to import the 3D model of the product, which could calculate the temperatures generated on the product under different operating conditions. Here we met the major issue of this master dissertation. The issue is using the boundary conditions for the temperature transition by conduction, convection, and radiation. The purpose of the simulation program would be to calculate the actual values of the temperatures on the product, as can be measured in an electrotechnical laboratory. Later will be that kind of simulation model useful for calculation temperatures of other electrical products between operating. For this purpose, it was necessary to determine the procedure for determining the boundary conditions of the temperature transition relative to the electrical properties of the product. A simulation model was developed and the process of determining the boundary conditions of the temperature transition was determined. Comparatively, the fuse switch disconnector was also measured in an electrotechnical laboratory, and the measured and calculated data were compared to each other.
