Abstract
U uvodnom izlaganju definirani su svi elementi koji direktno i indirektno utječu na sami postupak proračuna, kao što su vertikalne i horizontalne sile, utjecaj temperature na vodiče nadzemnih vodova, te drugi bitni pojmovi koji se tiču same konstrukcije i dimenzioniranja voda. Nakon što je utvrđeno na koje sve osnovne pojmove treba obratiti pozornost, obrađen je proračun provjesa metodom lančanice, te metodom parabole. Iz dobivenih rezultata može se zaključiti kako proračun preko parabole neznatno odstupa od proračuna preko lančanice, i u većini slučajeva ga možemo koristiti kao relevantnog u proračunu. Iz jednadžbe stanje direktno proizlaze i glavni kriteriji za konstrukciju nadzemnog voda, odnosno kriterij kritičnog raspona i kriterij kritične temperature, koji su od krucijalne važnosti za sami proračun. Na temelju proizvoljno odabranog zateznog polja dalekovoda, prikazan je kompletni mehanički proračun, na način na koji se to koristi i u praksi prilikom dimenzioniranja nadzemnih vodova.
Abstract (english)
In the opening exposure all elements that directly or indirectly affect on procedure of calculation are defined, such as vertical and horizontal forces, temperature effect on overhead line conductors, and other important terms that concerns construction and sizing of lines itself. After establishment of all basic terms needed to pay attention on, calculation of sag by catenary method and parabolic method has been processed. By the results of mentioned calculation can be cocluded that calculation by parabolic method slightly departs from calculation by catenary method, and in most cases we can use it as relevant in general calculation. From state equation directly results main criteria for construction of overhead lines, respectively the criterion of critical range, and the criterion of critical temperature, representing crucial importance for calculation itself. Based on arbitrarily chosen tension field line, complete mechanical calculation has been revealed, by the way it is used in practical work by sizing overhead lines.
