Abstract
Ovim završnim radom obuhvaćena je primjena visokonaponskih osigurača kao zaštitnog elementa visokonaponskih mreža i uređaja, koji iste štiti od struje kratkog spoja. Kao prvo, prikazan je princip rada visokonaponskih osigurača te njihova osnovna podjela prema nazivnom naponu elemenata postrojenja koji štite od kvarova. Zatim su se temeljito pojasnili principi prekidanja struje kao i taljenje vodiča u osiguraču koji se još naziva u rastalnicom. Kroz izvode formula i njihovih objašnjenja dat je krajnji prikaz formula za računanje struja bitnih za odabir osigurača. Nadalje, nakon objašnjavanja načina rada i osnovnih obilježja osigurača, a koja su važna za odabir visokonaponskih osigurača, prikazan je izbor osigurača za elemente postrojenja pomoću vremensko-strujne karakteristike osigurača. Nakon toga je, na konkretnim primjerima, dat prikaz odabira osigurača koji se koriste za zaštitu energetskih transformatora, mjernih naponskih transformatora, visokonaponskih motora te kondenzatorskih baterija.
Abstract (english)
The paper explores the usage of high voltage fuses in the high voltage network and in the other devices used as a protective element from the current electricity shortcut. Firstly, the way of high voltage fuses operation was given as well as its main classification according to rated voltage of facility elements used as breakdown protection. The priciples of current electricity shortcut were elaborated and the melting of conudctors known as fuse links was explained. Using formulas derivation and their explanation, the final formula for calculating current in fuse selection was also given. Furthermore, after the explanation of fuse operation and their main characheristics which are important for high voltage fuse selection, the fuse choice for facility elements was presented by using the fuse time-current characteristics. Finally, the real examples of fuse selection which are used for distribution transformer protection, voltage transformer protection, motor circuit protection and capacitor protection was outlined as well.
