Abstract

Diplomsko delo zajema pregled pravil, ki jih podaja standard SIST EN 50341-1:2013in nacionalni dodatek za nadzemne električne vode za izmenične napetosti nad 45 kV, ki temelji na podlagi SIST EN 50341-1:2002. Naloga obravnava določitev obtežb: obtežba vetra, obtežba žledu in napenjalne sile, ki delujejo na vodnike, zaščitno vrv in posledično na daljnovodni steber. Standar SIST EN50431- 1 - 2013 podaja splošna pravila za določitev obtežb in kombinacij, medtem, ko nacionaqlni dodatek natančno določa možne kombinacije obtežb, ki jih je potrebno zajeti pri snovanju in dimenzioniranju daljnovodnih stebrov. Na primeru 400 kV podpornega stebra je prikazana analiza določitve obtežb in kombinacij, ki delujejo na steber. Z globalno linearno elastično analizo smo določili notranje statične količine, ki smo jih uporabili za dimenzioniranje elementov. Kontrola nosilnosti prerezov in stabilnosti elementov je izvedana v skladu z veljavnimi Evorkod standardi SIST EN 1993.

Secondary title:	Design of 400 kV transmission tower
Secondary abstract:	The Diploma thesis adresses the overview of design rules given in SIST EN 50341 – 1 : 2013 and national annex for overhead electrical lines exceeding AC 45 kV based on SIST EN 50341 – 1 : 2002. In the thesis the folowing loads are analysed : wind load, ice load and tension force in the conductor wires. Standard SIST EN50341 – 1 : 2013 specifies general rules for determing loads and load combinations, while the national annex exactly defines possible combinations, which are needed to be included in design of transmission towers. The structural analysis and design is demonstrated for the case of 400 kV supported tower. Internal static forces, which were used to design elements of transmission tower, were determined using global linear elastic analysis. Cross-section capacity and element stability are performed according to Eurocode standards SIST EN 1993.
