Description
(54) ПЛАВКИЙ ПРЕДОХРАНИТЕЛЬ(54) FUSE FUSE
то нной толщине и-ширине токопровод щей пленки выдел емое тепло на единицу поверхности пленки и температура прилегающего к ней сло наЯол .нител пропорциональны удельному сопротивлению материала пленки.The heat produced by a unit surface of the film and the temperature of the adjacent layer of the nanoel, which is equal to the thickness and width of the conductive film, are proportional to the specific resistance of the film material.
Участки с повышенной температуроИ и повышенной утечкой чередуютс с участками, на которых температура и утечки возрастают незначительно, что предотвращает образование провод щего канала, шунтирующего токопровод цую пленку.Areas with elevated temperature and increased leakage alternate with areas where temperature and leakage increase slightly, which prevents the formation of a conductive channel that shunts a conductive film.
Предлагаемый малогабаритный предохранитель позвол ет защищать от коротких замыканий и перегрузок (в том числе гутавно нарастающих) маломощные цепи высокого напр жени до 5-10 кВ, которые в насто щее врем непосредственной защиты.не имеют.The proposed small fuse protects against short circuits and overloads (including increasing ones) the low-power high-voltage circuits up to 5-10 kV, which are currently not directly protected.
Фор1и Ула изобретени Плавкий предохранитель с плавкой вставкой, выполненной в риде токопровод щей пленки, нанесенной на диэлектрическое основание и помещенной в корпус с наполнителем, отличающийс тем, что, с целью увеличени уровн отключаемых напр жений и надежности срабатывани , токопровод ща пленка выполнена из чередующихс последователь-но соединенных участков из металлов и сплавов с резко отличающимис удельными сопротивлени ми, например NiCr и Ад. Formula Ula of the Invention Fuse with a fusible insert made in a wire of conductive film deposited on a dielectric base and placed in a housing with a filler, characterized in that, in order to increase the level of switchable voltages and reliability of operation, the conductive film is made of alternating followers but connected portions of metals and alloys with drastically different specific resistances, such as NiCr and Hell.
