Abstract:Težave pri umeščanju novih nadzemnih vodov v prostor postavljajo nov izziv, kako v največji možni meri izkoristiti obstoječe koridorje nadzemnih vodov in s tovrstnimi ukrepi prispevati k zmanjševanju površine zasedbe prostora. Polizolirani vodniki (pokriti prevodniki), ki so sestavljeni iz vodnika, obkroženega s prevleko iz izolacijskega materiala, ki ščiti pred naključnimi stiki z drugimi pokritimi vodniki in z ozemljenimi deli, kot so drevesne veje itd., omogočajo bolj jedrnato izrabo prostora. V doktorski disertaciji smo raziskali porazdelitev električnega polja polizoliranega vodnika in s poskusom ugotovili, da lahko obratuje pri najvišjih napetostih v gabaritu visoko napetostnih daljnovodov. Pri raziskavi segrevanja polizoliranega vodnika smo prazne prostore med žicami daljnovodne vrvi nadomestili z ekvivalentno geometrijsko plastjo ustrezne debeline. Tudi to predpostavko smo potrdili z meritvami. Z raziskavami smo pokazali, da je mogoče z minimalnimi gradbenimi in okoljskimi posegi praktično uporabiti polizolirane vodnike na visoki napetosti in s tem omogočiti zoženje koridorjev bodočih vodov najvišjih napetosti.

Title:Design of covered conductors
Abstract:Difficulties in locating new overhead lines in space pose a new challenge of how to use the most of existing overhead line corridors and contribute to reducing the area occupied by such measures. Covered conductors, consisting of a conductor surrounded by a coating of insulating material that protects against accidental contact with other covered conductors and with grounded parts such as tree branches, etc., allow more concise use of space. In our doctoral dissertation, we investigated the electric field distribution of a covered conductor and found by experiment that it can operate at EHV in the corridor of high-voltage power lines. In the study of the heating of a covered conductor, the empty spaces between the wires of the transmission line rope were replaced with an equivalent geometric layer of appropriate thickness. This assumption was also confirmed by measurements. Through research, we have shown that with minimal construction and environmental interventions, it is possible to practically use high-voltage covered conductors and thus enable the narrowing of the corridors of future EHV lines.
Keywords:covered conductor, electromagnetic field, temperature gradient, ampacity, measurements
