Abstract

V diplomskem delu je obravnavan vakuumski odklopnik, ki se zaradi ugodnih značilnosti in okolju prijazne tehnologije vgrajujejo v srednjenapetostne elektroenergetske objekte. Ob upoštevanju časovnega spreminjanja magnetnega polja so v programu Vector Fields - Opera, z metodo končnih elementov, analizirane elektromagnetne razmere 3D modela vakuumskega odklopnika s skodeličastimi kontakti, pri čemer je uporabljen tranzientni izračun. Za primerjavo je narejena še analiza razmer za spiralno in masivno obliko kontaktov, iz rezultatov analize pa je raziskan namen posebne oblike kontaktov vakuumskega odklopnika, ki je ključna za uspešno prekinitev električnega toka v vakuumu.

Secondary title:	Analysis of electrical and magnetic conditions of a vacuum circuit breaker
Secondary abstract:	This diploma thesis discusses the vacuum circuit breaker, which, due to its advantageous characteristics and environment-friendly technology, is installed into medium voltage power systems. While considering the time-varying of the electromagnetic field, electromagnetic conditions of a 3D model of a vacuum circuit breaker with contrate-cup shaped contacts are analysed. Therefor the software Vector Fields - Opera and his transient analysis is used in which solutions are obtained by the Finite Element Method. For the sake of comparison, an additional analysis of conditions for spiral as well as disc-shaped contacts was made. From the received results of the analysis, the purpose of the vacuum circuit breaker contacts' shape, which is crucial for a successful electric current interruption in vacuum, has been explored.
