Abstract
Изобретение используется для защиты трансформатора от короткого замыкания и от перегрузок. Упрощает установку и эксплуатацию устройства, повышает информативность индикации, снижает его габариты. Устройство имеет корпус (1), с одной стороны закрытый колпачком (6), с другой - пластиной (7) с проводящим элементом (8). Внутри размещен электромагнитный расцепитель (3) с магнитопроводом (9), катушкой (10), подпружиненным относительно него якорем (12), удерживающая якорь (12) направляющая (13). Якорь (12) выполнен с возможностью при разжатой пружине (17) занимать смещенное от осевой линии корпуса (1) положение, осуществлять перемещение перпендикулярно этой оси. Узел (4) управления расцепителем (3) состоит из параллельно соединенных самовосстанавливающегося предохранителя (20) и по крайней мере одного варистора (21). Напротив расцепителя (3) расположен механизм (2) свободного расцепления, включающий направляющий элемент (25) со втулкой (15), установленной внутри него отключающей пружиной (18) и размещенной внутри нее амортизационной пружиной (26). Через отверстия во втулке (15), направляющей (13), якоре (12), сердечнике (11) катушки (10) и колпачке (6) протянута нить (28), один конец которой соединен с амортизационной пружиной (26), а второй зафиксирован снаружи колпачка (6). В контактном колпачке (6) установлен указатель (5) срабатывания в виде стержня с продольным отверстием внутри. Движение указателя (5) осуществляется за счет воздействия толкающей трубки (29), надетой на нить (28) и перемещаемой при зацепе втулки (15) в отверстии якоря (12).The invention is used to protect the transformer from short circuit and overload. Simplifies the installation and operation of the device, increases the information content of the display, reduces its size. The device has a housing (1), closed on one side by a cap (6), and on the other, by a plate (7) with a conductive element (8). An electromagnetic release (3) with a magnetic circuit (9), a coil (10), an anchor (12) spring-loaded relative to it, an anchor (12) holding the guide (13) is placed inside. Anchor (12) is made with the possibility, when the spring (17) is unclenched, to occupy a position offset from the center line of the housing (1), to move perpendicular to this axis. The control unit (4) for the release (3) consists of a parallel-connected resettable fuse (20) and at least one varistor (21). Opposite the release (3) there is a free trip mechanism (2), including a guide element (25) with a sleeve (15), a disconnecting spring (18) installed inside it and a damping spring (26) placed inside it. Through the holes in the sleeve (15), the guide (13), the anchor (12), the core (11) of the spool (10) and the cap (6), a thread (28) is stretched, one end of which is connected to the damping spring (26), and the second fixed on the outside of the cap (6). In the contact cap (6) there is a trigger indicator (5) in the form of a rod with a longitudinal hole inside. The movement of the pointer (5) is due to the impact of the pushing tube (29), worn on the thread (28) and moved when the sleeve (15) is hooked in the hole of the armature (12).
