Abstract
U ovom radu opisan je problem udarnih struja koje nastaju pri samom uklopu transformatora. Glavna tema rada je proučavanje i pronalaženje najboljih metoda za smanjenje iste. U početku su predstavljene izvedbe i građa transformatora, a zatim smo udarne struje. To su struje koje mogu imati višestruko veće vrijednosti od nominalnih, koje imaju transformatori u radnim uvjetima, što može uzrokovati znatna oštećenja za stroj. Proučavanjem i istraživanjem, detaljno su opisani fenomeni udarnih struja, faktori koji utječu na njeno nastajanje i najbitnije, metode za smanjenje. U radu je opisano ukupno devet metoda za smanjenje udarnih struja, naravno ima ih i više, ali odabrane su neke od najpouzdanijih i najučinkovitijih. Također, odabrane metode za smanjenje udarne struje su jedne od najčešće korištenih, a u svakom potpoglavlju su detaljno opisane.
Abstract (english)
This paper describes the main problem with today's transformers, which is inrush currents. Inrush currents, which are occurring during the initial connection of the transformer, pose a significant problem for transformers, and the main focus of the paper was to study and find the best methods for reducing them. Initially, we focused on the design and construction of transformers to become familiar with some basics, and then we moved on to addressing the main topic, which is inrush currents. These are currents that can have values several times higher than the nominal values that transformers have under operating conditions, potentially causing significant damage to the machine. Through study and research, the phenomena of inrush currents, the factors influencing their occurrence, and most importantly, methods for reducing them are described in detail. A total of nine methods for reducing inrush currents are described in the paper; of course, there are more, but some of the most reliable and effective ones were selected. Additionally, the chosen methods for reducing inrush currents are among the most commonly used, and each subchapter provides a detailed description.
