Abstract
U završnom radu je obrađena teorijska pozadina transformatora te su provedena laboratorijska mjerenja kako bi se prikazao utjecaj spojeva namota i načina uzemljenja pri nesimetričnom opterećenju trofaznog transformatora. Opisana je građa transformatora, princip rada, prazni hod, kratki spoj, nadomjesna shema, uzemljenje, viši harmonici te vrste spojeva namota i njihov utjecaj na prilike u transformatoru. Detaljno je objašnjen utjecaj spojeva namota pri različitim opterećenjima pri čemu je najšire opisan utjecaj nesimetričnog opterećenja što je i tema samog završnog rada. Provedena su laboratorijska mjerenja u kojima je odrađen pokus praznog hoda i kratkog spoja transformatora na osnovu čijih su rezultata izračunati parametri nadomjesne sheme transformatora. Na temelju dobivenih mjernih rezultata iz pokusa opterećenja transformatora su prikazani strujno – naponski dijagrami gdje je vidljiv utjecaj različitih vrsta opterećenja na prilike u transformatoru te njihov međusobni odnos.
Abstract (english)
In this final paper is processed theoretical conception of transformers, and laboratory measurements which were performed to show the impact of winding connections and types of grounding at asymmetric load on the three – phase transformer. In this paper is described structure of transformers, work principles, no – load condition, short circuit condition, transformer equivalent circuit, types of grounding, impact of harmonics, types of winding connections and theirs impact on state in transformer. Completely is described impact of winding connections at different loads with emphasis on asymmetric load, which is the topic of this paper. In experimental measurements are performed no – load condition and short circuit condition in order to determine parameters of transformer equivalent circuit. Based on obtained measurement results in transformer load experiment are shown current – voltage diagrams which show impact of different types loads on transformer and their mutual relationship.
