Abstract
U ovom radu je napravljena analiza utjecaja na amplitudu, trajanje i oblik struje uklopa trofaznih transformatora. Pri korištenju osnovnih analitičkih izraza izvršen je proračun na primjeru trofaznog transformatora. Prilikom analize napravljen je osvrt na utjecaj remanentnog magnetizma i utjecaj trenutka uklopa trofaznog transformatora na amplitudu struje uklopa. Pri uklopu trofaznih transformatora, potrebno je znati vršnu vrijednost struje uklopa kako bih se zaštitna tijela unutar postrojenja mogla parametrirati. U slučaju uklopa, bez računanja na utjecaja struje uklopa na amplitudu, zaštitno tijelo bih moglo reagirati i isklopiti transformator odmah pri uklopu. U tom slučaju uklop transformatora bio bih onemogućen. Smanjenje struje je moguće također sklopovima za uklapanje transformatora, čiji se princip zasniva na temi ovog rada.
Abstract (english)
In this paper an analysis of the influence on the amplitude, duration and shape of the three-phase transformer current is made. For the use of basic analytical terms, a calculation was made on the example of a three-phase transformer. During the analysis, a review of the effect of residual flux density and the influence of the moment of switching the three-phase transformer to the amplitude of the current circuit was made. During the energizing a three-phase transformer, it is necessary to know the peak current value so that the protective elements inside the plant can be parameterized. In the case of switching, without counting the influence of the current switching on the amplitude, the protective body would react and switch off the transformer immediately upon energizing. In this case, the transformer switching would be disabled. Reduction of current is also possible by transformer installation circuits, whose principle is based on the subject of this work
