| description | The invention relates to the field of electrical engineering and can be used for protecting a transformer against short-circuiting and overloads in the primary winding.The device comprises a housing (1) in the form of a tube with contact caps (2, 3), an electromagnetic tripping mechanism (4), a unit (5) for controlling the tripping mechanism, a trip-free release mechanism (6) and an actuation indicator (7). The electromagnetic tripping mechanism (4) comprises a magnetic conductor (8), and an inductance coil (9) with a magnetic core (10) and an armature (11). The unit (5) for controlling the tripping mechanism comprises a resettable fuse (12) and a variable resistor (13), connected in parallel. The trip-free release mechanism (6) comprises a guide element (15), a bushing (16), an opening spring (17), a damping spring (18) and a monofilament thread (19).The invention makes it possible to achieve a simplification of the design, the absence of a reaction to current changes caused by voltage surges, to eliminate unwarranted cutting off of a consumer, to produce information about actuation of the device, and to increase safety.
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.
Изобретение относится к области электротехники и может быть использовано для защиты трансформатора от короткого замыкания и перегрузок в первичной обмотке.Предохранительное устройство содержит корпус (1) в виде трубы с контактными колпачками |
