20.500.12556/DKUM-55570 Vpliv gostote ovojev kabelskih snopov podzemnih vodnikov na obliko magnetnega polja Impact of the wrapping density of underground cables on the shape of the magnetic field Elektroenergetske kable uporabljamo za horizontalno, poševno in vertikalno polaganje v suhih in vlažnih prostorih, neposredno v zemlji, kabelskih kanalih pod vodo, na odprtem prostoru in v rudnikih. Električna energija se preko kablov običajno prenaša na krajših razdaljah, vendar se v svetu pojavlja vse več primerov uporabe kablov za najvišje napetosti in prenose na daljše razdalje. Pri tem med vodniki in kabli prihaja do raznih pojavov, ki so odvisni od tega, kako blizu skupaj imamo položene vodnike. V tem magistrskem delu bomo obravnavali primer vodnikov, ki so naviti v spiralo. Zanimalo nas bo, kako se spreminjajo vrednosti gostote magnetnega pretoka v odvisnosti od dveh parametrov, in sicer od spreminjanja razdalje, pri kateri vodnik naredi en obrat okoli svoje osi (gostota ovojev) in od spreminjanja medsebojne razdalje med vodniki. The electroenergetic cables we used for horizontal, skewed and vertical lay out in dry and wet places, directly in the earth, cable channels under water, an open space and in the mines. The electrical energy is transmitted through the cables usually in the shorter distances, but in the world it is used more and more examples of cables for the highest voltages and transmissions for longer distances. In doing so, the cables and wires occur for various effects. They depend on how close together we have puts the cables. In this thesis we will be showed wires, which are coiled in a helix. We will also examine how the change of the magnetic flux density values of the two parameters, namely the change of the distance in which the conductor makes a single turn around its axis (the density of turns) and of changing the mutual distance between the conductors. prenos električne energije magnetno polje vodniki in kabli transmission of electrical energy magnetic field wires and cables true true false P.
