Design modification of transformer housing

Diplomsko delo je nastalo v sodelovanju s podjetjem PREIS Sevnica, ki se ukvarja z izdelavo transformatorskih kotlov. Ciljna naloga je bila modifikacija konstrukcije v smeri poenostavitve proizvodnje iz tehnološkega vidika in vidika varilne tehnologije. Konstrukcija je morala kljub svojim spremembam zadoščati trdnostnim in togostnim kriterijem. V ta namen so bile izdelane numerične analize obratovalnih scenarijev, kot so: spodnji in zgornji dvig kotla ter podtlak in nadtlak v sistemu.The diploma thesis was created with cooperation with PREIS Sevnica company that is producing transformer housings. The objective of the thesis was to modify the construction in the way of simplification of production and welding technology. Despite its changes, the construction had to correspond to stress and deformation criteria. In order to prove the suitability of construction, various numerical analyzes were made such as the vertical lifting of transformer, over pressure, and under pressure of system
