Abstract

Cilj diplomske naloge je določiti podatke napisne ploščice enofaznega transformatorja in določiti nadomestno karakteristiko magnetnega kroga enofaznega transformatorja. Za določitev podatkov napisne ploščice so opravljene laboratorijske meritve karakteristik prostega teka, kratkega stika in segrevanja obremenjenega transformatorja. Nadomestna karakteristika magnetnega kroga je določena v obliki magnetno nelinearne karakteristike magnetnih sklepov in njihovih odvodov. Pravilnost metode za določitev nadomestne karakteristike magnetnega kroga je preverjena z izvedbo magnetno nelinearnega dinamičnega modela železnega jedra s primarnim navitjem. Vso delo v zvezi z diplomsko nalogo sem opravil v Laboratoriju za električne stroje na Fakulteti za elektrotehniko, računalništvo in informatiko, Univerze v Mariboru.

Secondary title:	Determining of nominal data and substitute magnetic-circuit characteristic of single-phase transformer
Secondary abstract:	The aim of the diploma work is determining of nominal data and substitute magnetic-circuit characteristic of single-phase transformer. For determining of nominal data the following tests were performed: no load test, short-circuit test, and temperature rise test of single-phase transformer. The substitute magnetic-circuit characteristic is given by magnetic flux linkage characteristic and its partial derivative. Correctness of the method for determination of substitute magnetic-circuit characteristic has been checked with developed magnetically nonlinear dynamic model of iron core with primary winding. The work was conducted in the Laboratory for electrical machines at the Faculty of Electrical Engineering and Computer Science.
