Abstract

Elektrodistribucijska podjetja stremijo k čim višji kakovosti in zanesljivosti dobavljene električne energije uporabnikom. S sodobnimi kablovodi lahko dosežemo višjo zanesljivost kot z nadzemnimi vodi. Pri vseh prednostih, ki jih prinašajo, pa moramo upoštevati različne vplive na kablovode na stopnji načrtovanja, polaganja in montaže kabelskega pribora ter zunanje dejavnike. Obratovanje kabla je odvisno od več dejavnikov, ki jih lahko upoštevamo že ob načrtovanju, in tako zmanjšamo tako stroške investicije (nižji stroški gradbenih del), in tudi stroške vzdrževanja. Z namenom zmanjševanja stroškov investicije je v programskem orodju Matlab in EleFAnT narejena primerjava vpliva zasipnih materialov za gradnjo zemeljskih vodov, saj je izkopano zemljo mogoče uporabiti tudi kot zasipni material. Povzeti so tudi drugi zunanji vplivi (atmosferske prenapetosti, način polaganja, vpliv narave) in rešitve, ki se uporabljajo v Sloveniji, kot tudi širše. Na koncu magistrskega dela so podani kriteriji za gradnjo kablovodov, koraki projektiranja kabelskega omrežja in kriteriji za izbiro vrste kabla.

Secondary title:	INFLUENCES ON THE OPERATION OF CABLES
Secondary abstract:	Electricity utilities are striving for highest possible quality and reliability of electricity supplied to customers. With modern cable construction higher reliability than with overhead lines can be achieved. With all advantages they bring, it also need to be considered different impacts on the cables at the stage of planning, laying and the mounting of the cable accessories and external factors. Operation of cable depends on several factors, which can be considered already at the planning stage and reduces both the investment costs (lower cost of construction), as well as maintenance costs. In order to reduce the cost of investment the comparison of the backfill materials in the programming tool Matlab and EleFAnT was made. Other external effects (atmospheric overvoltage, installation method and natural effects) and other solutions that are used in Slovenia and beyond are presented. At the end are given conditions for the construction of cables, cable network design steps and conditions for selecting the type of cable.
