Abstract

Izum se nanaša na stikalo (S) za zaščito električnega tokokroga proti preobremenitvam. Stikalo (S) v osnovi sestoji iz prožilnega sklopa (A) in prekinjevalnega sklopa (B), pri čemer prožilni sklop (A) obsega indukcijsko enoto (1), termični odklopnik (2) in udarno iglo (3). Indukcijska enota (1) obsega tuljavo (12) z jarmom (14) za premikanje udarne igle (3) v smeri proti prožilnemu sklopu (B) v primeru kratkostičnega toka, ko se v tuljavi generira magnetno polje. Termični odklopnik (2) obsega bimetalno membrano (20), ki je mehansko povezana z udarno iglo (3) in se ob pojavu nadtoka v tokokrogu in segrevanju premakne v smeri proti prekinjevalnemu sklopu (B). Z namenom, da bi stikalo (S) omogočalo tudi zaščito električnega tokokroga proti transientnim napetostim, npr. v primeru strele, je stikalo (S) v območju prožilnega sklopa (A) opremljeno tudi z varistorjem (4), ki se nahaja v toplotno-prevodnem stiku z omenjenim termičnim odklopnikom (2).

  1. Stikalo za zaščito električnega tokokroga proti preobremenitvam SPREMENJEN PATENTNI ZAHTEVEK
  2. 1. Stikalo (S) za zaščito električnega tokokroga (L], L2; Ni, N2) proti preobremenitvam, obsegajoče za medsebojno sodelovanje prirejena prožilni sklop (A) prekinjevalni sklop (B), pri čemer je prekinjevalni sklop (B) predviden za prekinitev vsakokratnega električnega tokokroga (L|, L2; Ni, N2), ki ga tvori vsaj en fazni vodnik (Li, L2) in vsaj en ničelni vodnik (Ni, N2) vključno z omenjenim stikalom (S) in vsaj enim električnim porabnikom oz. bremenom, kadar od prožilnega sklopa (A) prejme temu ustrezen impulz, in pri čemer prožilni sklop (A) obsega indukcijsko enoto (1), termični odklopnik (2) in udarno iglo (3) za posredovanje impulza prekinjevalnemu sklopu (B) z namenom prekinitve omenjenega tokokroga, pri tem pa indukcijska enota (1) sestoji vsaj iz okrova (11) v funkciji elektromagnetnega jarma, nadalje iz v omenjen električni tokokrog (Li, L2; Ni, N2) električno povezljive in v toplotno-prevodnem odnosu z omenjenim termičnim odklopnikom (2) nahajajoče se tuljave (12) v funkciji generatorja magnetnega polja zaradi inducirane napetosti ob pojavu kratkostičnega toka v tokokrogu, kot tudi iz kotve (14), ki je mehansko povezana z omenjeno udarno iglo (3), ki je pod vplivom magnetnega polja omenjene tuljave (12) v svoji aksialni smeri premakljiva vsaj proti prožilnemu sklopu (B), medtem ko je termični odklopnik (2) razporejen v neposredni bližini omenjene indukcijske enote (1), s katero je v toplotno-prevodnem stiku, in obsega bimetalno membrano (20), ki je mehansko povezana z omenjeno udarno iglo (3) in je zaradi segrevanja kot posledice nadtoka v omenjenem tokokrogu skupaj z udarno iglo (3) iz svojega izhodiščnega položaja premakljiva v aksialni smeri omenjene udarne igle (3) proti prekinjevalnemu sklopu (B) zaradi generiranja impulza in prekinitve omenjenega električnega tokokroga, in pri čemer omenjeno stikalo (S) nadalje obsega varistor (4), ki je v toplotno-prevodnem odnosu s termičnim odklopnikom (2), pri čemer je - bodisi prvi električni pol varistorja (4) električno povezan s faznim vodnikom (Li, L2) električnega tokokroga (Li, L2; Ni, N2), preostali električni pol varistorja (4) pa z ničelnim vodnikom (Ni, N2) električnega tokokroga (Li, L2; Ni, N2), - ali pa je prvi električni pol varistorja (4) električno povezan s faznim vodnikom (Li, L2) električnega tokokroga (Li, L2; Ni, N2), preostali električni pol varistorja (4) pa z ozemljitvenim vodom električnega tokokroga (Li, L2; Ni, N2), označeno s tem, daje omenjena tuljava (12) obdana z omenjenim varistorjem (4), ki predstavlja varistor (4) v obliki votlega valja, med omenjeno tuljavo (12) in omenjenim varistorjem (4) pa je vzpostavljeno toplotno-prevodno razmerje.
