Abstract
V delu je predstavljena problematika dušilk, vgrajenih v energetskih transformatorjih. Z električnega vidika sta analizirani obe znani izvedbi dušilk, poleg teh je predstavljen predlog za novo izvedbo dušilke. Posebej je osvetljena problematika različnih kratkostičnih obratovalnih stanj in obnašanje posameznih tipov dušilk z električnega vidika. Predstavljeni so izračuni vseh glavnih električnih parametrov dušilk in primerjave oziroma razlike med različnimi tipi. Za vse tri izvedbe dušilke je izpeljan izračun mehanskih kratkostičnih obremenitev. Obravnavano je elektromagnetno polje in izračun induktivnosti. Na konkretnem primeru je za vse tri izvedbe dušilke predstavljen izračun glavnih električnih in konstrukcijski parametrov ter primerjava med njimi. Izkaže se, da z novo predlagano izvedbo dušilke zmanjšamo količino vgrajenega materiala pri enakih glavnih električnih parametrih dušilke. Na koncu so predstavljene še prednosti in slabosti posameznih izvedb dušilk.

Title:
DESING AND DEVELOPMENT OF INDUCTOR FOR POWER TRANSFORMER
Abstract:
The thesis deals with reactors installed inside power transformers. Two known types of reactors are analyzed in terms of short circuit behavior and electrical characteristics. A new type of reactor is presented and analyzed. Comparison between new and existing types of reactors is presented together with detailed analysis of magnetic field and inductivity. Benefit for new type of reactor is more efficiently used material. Calculation of reactor basic electrical parameters is presented. All three types of reactors are analyzed in order to present benefits and drawbacks for all three reactors types.
