20.500.12556/RUL-148513 Mehanska analiza jarmskih letev v energetskem transformatorju Mechanical analysis of clamping frame in power transformers Ključen sestavni del energetskega transformatorja predstavlja sestav magnetnega kroga z opremo, od katerega so osnovni konstrukcijski element jarmske letev. Te so ene od najbolj obremenjenih komponent celotnega sestava, zato jih želimo trdnostno preveriti. V nalogi smo izvedli mehansko analizo s pomočjo metode končnih elementov. Tu smo obravnavali trodimenzionalni model zgornje in spodnje jarmske letve. Te smo analizirali v stanju dviga aktivnega dela, ko so obremenitve največje. Ugotovili smo, da so za obravnavani primer jarmske letve trdnostno primerne. Določili smo mesta koncentracij napetosti in opredelili nekaj smernic pri konstruiranju sklopa. The key component of the power transformer is the magnetic circuit, of which the yoke laths are the central structural element. These are the most stressed parts of the entire assembly, which is why we want to perform a mechanical analysis on them. In this assignment we performed a mechanical analysis whit finite element method. We analyzed three-dimensional models of upper and lower yoke laths in the state of manipulation of the active part, when the loads are biggest. We concluded that the design of yoke laths for the project in question are mechanically suitable for use. We determined the locations of stress concentrations and defined some guidelines for the process of modeling yoke laths. metoda končnih elementov mehanska analiza deformacijsko-napetostno stanje energetski transformator magnetni krog jarmske letve finite element method mechanical analysis deformation-stress state power transformer magnetic circuit yoke lath true false false [R.
