INDUCTOR FOR LARGE SHORT CIRCUIT CURRENTS

V diplomski nalogi je obravnavana zračna dušilka, ki se znotraj laboratorija ICEM-TC uporablja pri preskusih z velikimi tokovi. Dušilka je sestavljena iz šestih enakih tuljav, ki jih lahko poljubno povežemo v tokokroge, kar predstavlja izredno veliko število kombinacij vezav dušilke. Za določitev parametrov vseh kombinacij dušilke je bil izdelan analitični model. Rezultati analitičnega izračuna so, za naključno izbrane kombinacije, primerjani tako z numeričnim izračunom kakor z meritvami.In diploma work the air inductor unit, applied for high short circuit currents testing in power laboratory ICEM-TC, is dealt. That inductor unit is composed by six coils, which could be connected in many different ways, that finally leads to the enormous number of possible combinations. For defining parameters of the whole possible combinations the analytical method is proposed. Some results of analytical method are compared firstly by results of dynamic model and secondly by actual measurements in power laboratory
