Abstract

Invenţia se referă la domeniul electrotehnicii şi poate fi utilizată pentru a proteja transformatorul de scurtcircuit şi suprasarcini în înfăşurarea primară.Dispozitivul de siguranţă conţine un corp (1) în formă de ţeavă cu capace de contact (2, 3), un declanşor electromagnetic (4), un bloc (5) de comandă a declanşorului, un mecanism de declanşare liberă (6), şi un indicator de declanşare (7). Declanşorul electromagnetic (4) conţine un conductor magnetic (8), o bobină (9) de inductanţă cu un miez magnetic (10) şi o armătură (11). Blocul (5) de comandă a declanşorului conţine o siguranţă autoregeneratoare (12) şi un varistor (13), conectaţi în paralel. Mecanismul de declanşare liberă (6) conţine un element de ghidare (15), o bucşă (16), un arc de declanşare (17), un arc amortizor (18), şi un monofilament (19).Dispozitivul permite obţinerea unei simplificări a construcţiei, absenţa unei reacţii la modificările curentului, cauzate de supratensiuni de impuls, eliminarea deconectărilor nejustificate ale consumatorilor, obţinerea informaţiei despre declanşarea dispozitivului, precum şi creşterea siguranţei.
