Description
Затем подают напр жение с обратным пор дком чередовани фаз на обмотку добавочных потерь 7. При пересечении короткозамкнутой пусковой обмоткой 3 переменного магнитного пол , индуктируемого обмоткой добавочных потерь 7, в пусковой обмотке 3 паводитс электродвижуща сила и протекает ток, разогревающий обмотку.Then the voltage is fed in reverse order of phase alternation to the winding of the additional losses 7. When the short-circuited starting winding 3 of the alternating magnetic field intersects the additional losses 7, the electromotive force starts flowing in the starting winding 3 and the current warming the winding flows.
Кроме того, разогрев происходит за счет перемагничивани и создани вихревых токов в теле ролика.In addition, warming up occurs by reversing and creating eddy currents in the body of the roller.
Таким образом, все основные тепловыделепи происход т в приводном ролике, а не внутри него, что позвол ет повысить верхний предел установленной температуры, не перегружа при этом подшипники и индуктор излишними тепловыми нагрузками.Thus, all of the main heat generation occurs in the drive roller, and not inside it, which allows the upper limit of the set temperature to be increased without overloading the bearings and the inductor with excessive thermal loads.
Температура поверхности ролика регулируетс за счет изменени напр жени на обмотке добавочных потерь 7.The surface temperature of the roller is controlled by varying the voltage on the winding of the additional loss 7.
Предмет изобретени Subject invention
Устройство дл нагрева длинномерного волокнистого материала, содержащее приводной ролик и расположенный внутри него магнитопровод , в радиальных пазах которого размещена обмотка индуктора, а также источник переменного напр жени , отличающеес тем, что, с целью увеличени тепловыделени приводпого ролика, магнитопровод снабжен обмоткой добавочных потерь, уложенной в его радиальных пазах и подключенной к источнику переменного напр жени с пор дком чередовани фаз обратным пор дку чередовани фаз индуктора.A device for heating a long fiber material, containing a drive roller and a magnetic core inside it, in the radial grooves of which the inductor winding is placed, as well as an alternating voltage source, characterized in that, in order to increase the heat generation of the drive roller, the magnetic conductor is provided with a winding of additional losses laid in its radial grooves and connected to the source of alternating voltage with the order of phase alternation the reverse order of phase alternation of the inductor.
