Abstract:Magistrsko delo zajema opis, analizo magnetnih razmer s pomočjo metode končnih elementov, projektiranje ter zagon celotnega procesa justiranja relejev FI, ki so sestavni del ETI-jevega prodajnega programa in so namenjeni vgradnji v elektromehanska zaščitna EFI stikala na diferenčni tok ter kombinirana zaščitna stikala KZS, ki vsebujejo poleg diferenčne zaščite tudi preobremenitveno in kratkostično zaščito. Na zanesljivost delovanja diferenčnega dela zaščite v primerih obeh zaščitnih stikal (tako EFI kot KZS) v veliki meri vpliva kvaliteta izdelave prožilnega releja ter njegovo justiranje, saj lahko le tehnološko brezhiben in ustrezno justiran rele zagotavlja zanesljivo in varno delovanje zaščitnih stikal na diferenčni tok EFI in KZS. V magistrskem delu je predstavljen opis posameznih komponent celotnega sistema, izvedba ter rezultati simulacije s pomočjo ustreznega programskega orodja ter postopek avtomatizacije celotnega sistema, vključno z uporabljenimi gradniki avtomatizacije.
Keywords:rele FI, metoda končnih elementov, magnetilna tuljava, avtomatizacija procesa.

Title:MAGNETIC ADJUSTMENT OF FI RELAYS
Abstract:In present master thesis magnetic circumstances are described and analyzed using finite element method. Design and launch of complete FI relay adjustment system are determined since FI relays used in residual current circuit breakers (RCCBs) and residual current circuit breakers with overcurrent, differential and short circuit protection (RCBOs) are an integral part of ETI company product assortment. The reliability of differential protection components in both types of residual current circuit breakers (RCCBs and RCBOs) is greatly affected by the quality of the tripping relay production and adjustment. Only technologically faultless and appropriately adjusted relays ensure reliable and safe operation of RCCBs and RCBOs. Present thesis describes individual components of the system, introduces implementation and simulation results with appropriate software and establishes procedure for automation of the system including automation elements.
Keywords:FI relay, finite element method, magnetic fixture, process automation
