Abstract
Pri električni varovalki, ki je še zlasti predvidena za zaščito enosmernih (DC) električnih tokokrogov, je vsaj v vsakem izmed končnih območij (31, 32) talilnega elementa (3) v notranjosti okrova (1), namreč med vsakokrat pripadajočim nožastim kontaktom (210, 220) in vsakokrat slednjemu najbližjo oslabitvijo (30, 30', 30"), na vsaki izmed vsaksebi obrnjenih dominantnih površin (33, 34) talilnega elementa (3) nanešena vsaj po ena prepreka (51, 51', 51"; 52, 52', 52") za preprečevanje napredovanja električnega obloka, ki je usmerjena v prečni smeri talilnega elementa (3) vzdolž vsake izmed omenjenih dominantnih površin (33, 34) in poteka po celotni širini traku talilnega elementa (3), sestoji pa iz gibkega in vsaj kratkotrajno temperaturno obstojnega gradiva.
Claims (4)
- SPREMENJENI PATENTNI ZAHTEVKI1. Električna varovalka, obsegajoča cevasto zasnovan okrov (1) iz električno izolativnega materiala, ki je na konceh (11, 12) zaprt s togima pokrovoma (21, 22), od katerih vsak obsega z njim togo povezan nožast kontakt (210, 220) iz električno prevodnega materiala, medtem ko je v notranjosti omenjenega okrova (1) vgrajen kot ploščat trak iz električno prevodnega materiala vnaprej določene električne upornosti zasnovan talilni element (3) vnaprej določene dolžine (L) in debeline, ki je po eni strani v svojih končnih območjih (31, 32) električno povezan z omenjenima nožastima kontaktoma (210, 220) in po drugi strani opremljen z množico vzdolž traku med seboj enakomerno razporejenih in glede na trak v prečni smeri potekajočih oslabitev (30, 30', 30) v obliki perforacij omenjenega traku med obema dominantnima površinama (33, 34) le-tega, pri čemer je vsakokratna oslabitev (30, 30', 30) na voljo kot množica med seboj v prečni smeri traku enakomerno razporejenih skoznjih lukenj (300), tako da je prečni presek talilnega elementa (3) v vsaki izmed omenjenih oslabitev (30, 30', 30) vnaprej določen in manjši od preseka talilnega elementa (3) v preostalih območjih le-tega, obenem pa je notranjost t.j. svetlina omenjenega okrova (1) zapolnjena s sipkim negorljivim sredstvom (4), še zlasti s kremenčevim peskom, s katerim je obdan omenjen talilni element (3), označena s tem, daje vsaj v vsakem izmed končnih območij (31, 32) omenjenega talilnega elementa (3), namreč med vsakokrat pripadajočim nožastim kontaktom (210, 220) in vsakokrat slednjemu najbližjo oslabitvijo (30, 30', 30), na vsaki izmed vsaksebi obrnjenih dominantnih površin (33, 34) talilnega elementa (3) nanešena vsaj po ena prepreka (51, 5Γ, 51; 52, 52’, 52), in s tem, daje vsaj ena prepreka (51, 5 Γ, 51; 52, 52', 52) na voljo med vsaj še dvema nadaljnjima oslabitvama (30, 30', 30) na talilnem elementu (3), pri čemer je vsaka izmed omenjenih preprek v profilu približno polkrožna (51, 51', 51; 52, 52', 52) in sestoji iz gibkega in vsaj kratkotrajno temperaturno obstojnega gradiva, prirejena pa je za preprečevanje napredovanja električnega obloka in usmerjena v prečni smeri talilnega elementa (3) vzdolž vsake izmed omenjenih dominantnih površin (33, 34) ter poteka po celotni širini traku talilnega elementa (3), in pri čemer je vsaka izmed končnih, namreč najbližje nožastima kontaktoma (210, 220) razporejenih preprek (51, 5Γ, 51; 52, 52', 52) od pripadajočega nožastega kontakta (210, 220) oddaljena za vnaprej določeno razdaljo (T), ki znaša približno 15% dolžine (L) talilnega elementa (3).
- 2. Električna varovalka po zahtevku 1, označena s tem, da premer (D) vsakokratne prepreke (51, 5 Γ, 51; 52, 52', 52) znaša 2-6 mm.
- 3. Električna varovalka po zahtevku 2, označena s tem, da premer (D) vsakokratne prepreke (51, 5Γ, 51; 52, 52', 52) znaša 3-4 mm.
- 4. Električna varovalka po kateremkoli od zahtevkov 1 - 7, označena s tem, da vsakokratna prepreka (51, 5Γ, 51; 52, 52', 52) sestoji iz silikona, ki je vsaj kratkotrajno odporen proti temperaturi najmanj 2000°C.
