Abstract:Diplomsko delo obravnava vpliv enosmerne železniške vleke na zaslone srednjenapetostnih kablovodov ter izbiro ustrezne prenapetostne zaščite. Predstavljeni so vplivi uhajavih tokov, načini ozemljevanja kabelskih zaslonov in nastanek induciranih napetosti. Na realnem primeru 20 kV kablovoda AXAL-TT PRO dolžine 1656 m je bil izveden teoretični izračun, simulacija in meritev inducirane napetosti. Primerjava rezultatov je pokazala dobro ujemanje med izračunom, modelom in meritvami. Na podlagi dobljenih rezultatov je bila izvedena izbira prenapetostnega odvodnika za zaščito kabelskega zaslona.
Keywords:enosmerna železniška vleka, kabelski zaslon, inducirana napetost, ozemljevanje kabelskih zaslonov, prenapetostni odvodnik

Title:The influence of DC stray currents from railway traction on MV cable line screens and selection of surge arrester
Abstract:The diploma thesis discusses the influence of DC railway traction on medium-voltage cable screens and the selection of appropriate surge protection. The effects of stray currents, cable screen grounding methods, and the occurence of induced voltages are presented. A theoretical calculation, simulation and field measurments of induced voltage on the cable screen were performend on a 20 kV AXAL-TT PRO cable line with a length of 1656 m. The comparison of results showed similar results between calculation, simulation model and measurments. Based on the obtained results, a suitable surge arrester was selected for the protection of the cable screen.
Keywords:DC railway traction, cable screen, induced voltage, cable screen grounding, surge arrester
