20.500.12556/DKUM-18374 DELOVANJE VISOKONAPETOSTNE VAROVALKE V KOMBINACIJI Z LOČILNIM STIKALOM OPERATION OF HIGH VOLTAGE FUSES IN COMBINATION WITH SWITCH-DISCONNECTOR V diplomski nalogi je podana raziskava o delovanju visokonapetostnih varovalk v kombinaciji z ločilnim stikalom in zanesljivosti starejših visokonapetostnih varovalk. Predstavljeno je teoretično delovanje visokonapetostnih varovalk in podan zgodovinski razvoj varovalk. Opisan je način izbire primernih visokonapetostnih varovalk in pripadajoči preskusi. Izvedeni so bili preskusi delovanja novih in starejših varovalk in izmerjene sile udarnih igel pri delovanju visokonapetostnih varovalk. Izvedena je bila analiza delovanja starih, že uporabljenih visokonapetostnih varovalk. This diploma work presents a survey on how high-voltage fuses function in combination with a release switch and the adequacy of older high-voltage fuses. It illustrates the theoretical functioning of high-voltage fuses along with their history review, and also the presentation of the current major producers of those products. A method of appropriate high-voltage fuses selection and associated tests are described. A test of newer and older fuse functioning was conducted. The force of firing pins in the functioning of the high-voltage fuses were obtained by laboratory measurements. An analysis of the functioning of old, already used high-voltage fuses was also conducted. visokonapetostna varovalka ločilno stikalo udarna igla sila high voltage fuse switch disconnector striker force true true false [G.
