20.500.12556/RUL-117034 Prenova konstrukcije in optimizacija termo sprožilnika visokonapetostnih varovalk High voltage thermal striker redesign and optimisation V magistrski nalogi je opisan razvoj nove konstrukcije termo sprožnika visokonapetostnih varovalk. Na začetku smo opisali delovanje talilnih vložkov in pomen uporabe termo sprožnika v visokonapetostni varovalki. Izvedli smo analizo obstoječe konstrukcije ter analizirali konkurenco ter pregledali veljavnost patentov. Določili smo tehnične zahteve, ki smo jih upoštevali pri razvoju nove generacije sprožnika. Pri razvoju smo za odkrivanje napak in njihovih posledic izdelali tudi FMEA analizo. Z orodji metodike konstruiranja smo izdelali morfološko matriko ter s sintezo rešitev določili tri variante ter jih ovrednotili. Za izbrano rešitev smo izdelali prototipe in kasneje s testiranji potrdili ustreznost nove konstrukcije termo sprožnika. The master thesis describes the development of a new engineering design of a thermal striker for high-voltage fuses. The thesis starts with the description of the fuse-links functioning and the importance of using a thermal striker in a high-voltage fuse. Furthermore, the thesis includes an analysis of the existing structure, an analysis of the competition products and a review of related patents. The technical requirements document was created that was carefully considered during development of the new generation of the striker. Design FMEA analysis was conducted to detect potential failure modes and their consequences. Morphological matrix was created by using methodology of design tools. Three design variants were set-up and evaluated by synthesising solutions. Several thermal striker prototypes of the selected solution were made and validated by systematic testing. termo sprožniki visokonapetostne varovalke morfološka matrika FMEA analiza prenova konstrukcije termo delovanje kratkostično delovanje thermo strikers high voltage fuses morphological matrix FMEA analysis upgrade of construction thermal effect short circuit operation true false false [B.
