Description
(54) ИНДУКТОР ДЛЯ НАГРЕВА(54) HEATED INDUCTOR
дуктора, Обращенном к нагревательному изделию . На пр молинейных участках токопровода пути тока по каждому из продольных сечений равны, в св зи с чем равны их сопротивлени , и ток равномерно распредел етс по сечению токопровода.Duktor, Appealed to the heating product. In the rectilinear sections of the current path, the current path over each of the longitudinal sections is equal, therefore, their resistances are equal, and the current is evenly distributed over the conductor cross section.
Криволинейные участки токопровода имеют различную длину наружного и внутреннего контуров. Токонесущий слой у внутреннего контура, располага сь по выступам волны , здлин ет путь то-ка, благодар чему увеличивает сопротивление участка и обеспечивает равномерное распределение тока по сечению токопровода без изменени реактивной мощности, т. е. без снижени к.п.д. индуктора .Curved sections of the conductor have different lengths of the outer and inner contours. The current-carrying layer at the inner contour, located along the protrusions of the wave, increases the path of the current, thereby increasing the resistance of the section and ensures a uniform current distribution over the conductor cross section without changing the reactive power, i.e. inductor.
Эффективна толщина токонесущего сло токопровода зависит от свойств материала и частоты тока, например дл медного токопровода при частоте 70 кгц толщина составл ет 0,8 лгм.The effective thickness of the current-carrying layer of the conductor depends on the material properties and the frequency of the current, for example, for a copper conductor at a frequency of 70 kHz, the thickness is 0.8 lgm.

Индукто.р дл нагрева, содержащий токопровод , изогнутый по форме нагреваемого объекта, внутренн поверхность которого выполнена переменного сечени в местах сгиба , и систему его охлаждени , отличающийс тем, что, с целью повыщени к.п.д. путем снижени реактивного сопротивлени , переменное сечение образовано волнообразной поверхностью с направлением волны по длине токопровода, причем высота выступов волны линейно уменьшаетс по его щирине.Inducto.R for heating, comprising a conductor, curved in the shape of the object being heated, the inner surface of which is made of variable cross section at the bend points, and its cooling system, characterized in that, in order to increase the efficiency by reducing the reactance, the variable cross section is formed by a wave-like surface with the direction of the wave along the length of the conductor, with the height of the protrusions of the wave linearly decreasing along its width.
