20.500.12556/DKUM-48374 OPTIMIZACIJA ELEMENTOV MAGNETNEGA TOKOKROGA V ZAŠČITNEM STIKALU NA DIFERENČNI TOK EFI-4 40/003A MAGNETIC CIRCUIT OPTIMIZATION OF RESIDUAL-CURRENT CIRCUIT BREAKER EFI-4 40/003A Namen diplomske naloge »Optimizacija elementov magnetnega tokokroga v zaščitnem stikalu na diferenčni tok EFI-4 40/003 A tip« je, izboljšanje zanesljivosti delovanja stikala na diferenčni tok, da s tem še vedno ustreza IEC standardom. Diplomska naloga je nastala v sodelovanju s podjetjem ETI d.d. V prvem delu so opisani vsi elementi stikala na diferenčni tok in njegovo delovanje. V drugem oziroma glavnem deluje bila sprva opravljena analiza slabih vzorcev, v nadaljevanju pa je opisana merilna oprema in postopki optimizacije stikala, rezultati ter predlagane rešitve. The purpose of my diploma paper »Magnetic circuit optimization of residual-current circuit breaker EFI-4 40/003 A type « is to improve the reliability of the residual current circuit breaker working yet still meet the IEC standards. My diploma paper was made in collaboration with ETI d.d. . The first part of my diploma paper includes a description of all the elements of the residual current circuit switch and its working. The second or the main part of the diploma paper first describes the performed analysis of the bad patterns. Further on it describes the measuring equipment and the procedure of the switch optimisation, the results and the suggested solutions. zaščitno stikalo diferenčni tok magnetni tokokrog Circuit breaker residual current magnetic current true true false [U.
