20.500.12556/DKUM-17011 ANALIZA ELEKTROMAGNETNIH RAZMER V IZOLATORJU IN OKOLICI PRI UPRABI POLIZOLIRANEGA VODNIKA THE ANALYSIS OF ELECTROMAGNETIC CONDITIONS IN THE INSULATOR AND THE SURROUNDING AREA BY USING OF COVERED CONDUCTOR V diplomski nalogi so proučene elektromagnetne razmere in izvedene analize dogajanja v keramičnem izolatorju s kovinsko pritrdilno sponko pri uporabi polizoliranega vodnika. S pomočjo programskega orodja Opera Vector Fields so bili opravljeni 3D numerični izračuni razmer v izolatorju ter njegovi okolici, enega od komercialnih proizvajalcev elektro opreme. V odvisnosti od materialov, obstoječe geometrije in časovno tokovnih razmer je prikazana porazdelitev električne poljske jakosti v izolatorju ter njegovi okolici in vrtinčni tokovi v bljižnjih kovinskih delih. S tem je prikazana pomembnost izbire izolacijskih materialov na porazdelitev elektromagnetnih veličin ter dogajanj v izolatorju, ki lahko pripeljejo do resnih poškodb materialov. Na podlagi dobljenih rezultatov je predstavljena tehnična rešitev obravnavanega problema. This thesis examines the electromagnetic situation and analysis of developments in the ceramic insulator with a metal clamp, with covered conductor. Using a software tool Opera Vector Fields were carried out 3D numerical calculations of the situation in the insulator and its surroundings, one of the commercial electrical equipment manufacturers. Depending on the materials, the existing geometry and time-flow conditions shows the distribution of electric field strength in the insulator and the surrounding area and eddy currents of nearby metal parts. This shown the importance of the choice of insulation materials on the distribution of electromagnetic parameters and events in the insulator, which can lead to serious damage to materials. According to the results presented technical solution of the problem. izolatorji vzmetne sponke polizolirani vodniki elektromagnetne razmere parcialne razelektritve insulators clamps covered conductors electromagnetic situations partial discharges true true false [P.
