Description
В насто щее врем многожильные кабели св зи с чувствительной к влаге изол цией (бумажной и т. п.) сушатс в неподвижном состо нии намотанными на барабаны или в бухты. Дл этого барабаны с кабелем помещаютс в вакуум-котел и нагреваютс паром и посто нным током, пропускаемым по их жилам. Этот способ нагрева исключает возможность конвейерной сущки кабел .Currently, multi-conductor communication cables with moisture-sensitive insulation (paper, etc.) are dried in a stationary state wound on drums or in coils. For this, the drums with the cable are placed in a vacuum boiler and heated with steam and direct current passed through their veins. This method of heating eliminates the possibility of the conveyor of the cable.
Применение предлагаемого способа дает возможность осуществл ть сушку подобных кабелей путем пропуска его сквозь индуктор и нагрева индукционным методом в переменном электромагнитном поле.The application of the proposed method makes it possible to dry such cables by passing it through an inductor and heating it by an induction method in an alternating electromagnetic field.
Такой способ позвол ет осуществить сушку изол ции кабел в процессе его передвижени от одной технологической операции к другой, сушку любого заданного участка кабел (в услови х производства или эксплуатации) и значительно сократить длительность процесса сушки.This method allows drying of the insulation of the cable during its movement from one technological operation to another, drying of any given cable section (in terms of production or operation) and significantly reducing the duration of the drying process.
На чертеже изображена схема сушки кабел ло предлагаемому способу .The drawing shows a diagram of the drying cable of the proposed method.
Кабель / прот гиваетс через индуктор (соленоид) 2, обтекаемый переменным током. Переменное магнитное поле индуктирует в каждой жиле 3 кабел вихревые токи, которые осуществл ют нагрев и передачу выдел екого при этом тепла дл нагрева изол ционного покрова 4. Равномерный и быстрый нагрев всей изол ции кабел обеспечиваетс равномерным распределением жил по его сечению. Скорость сушки зависит ог параметров электромагнитного пол и количества жил в кабеле.The cable / is pulled through an inductor (solenoid) 2, flowing around an alternating current. An alternating magnetic field induces in each conductor 3 of the cable eddy currents that heat and transfer heat while heating the insulation of the insulation 4. The uniform and rapid heating of the entire insulation of the cable is ensured by an even distribution of the conductors over its cross section. The drying rate depends on the parameters of the electromagnetic field and the number of wires in the cable.
