Description

где p--удельное сопротивление материала жилы.where p is the resistivity of the core material.

Известно, что в проволочных резисторах одной из основных причин отказов  вл етс  потер  проводимости в контактных узлах. Поэтому отсутствие в резисторах, изготовленных по предлагаемому способу, промежуточного контактного узла между обмотками в эмалевой и стекл нной изол ции ввиду выполнени  их в виде одного отрезка провода повышает надежность системы.It is known that in wire resistors one of the main causes of failures is the loss of conductivity at the contact nodes. Therefore, the absence of an intermediate contact node between the windings in the enamel and glass insulation in the resistors manufactured by the proposed method due to their execution in the form of a single wire segment increases the reliability of the system.

Лабораторные испытани  показали, что в месте стыка эмалевой и стекл нной изол ции пробойное напр жение не ниже, чем дл  стекл нной изол ции, а допустимый радиус изгиба равен донустимому радиусу изгиба микропровода в стекл нной изол ции.Laboratory tests showed that the breakdown voltage at the junction of the enamel and glass insulation is not lower than for glass insulation, and the allowable bending radius is equal to the allowable bending radius of the microwire in the glass insulation.

Способ по сн етс  чертежом (резистор изготовлен предлагаемым способом) где: 1- пазовый каркас, 2- обмотка из микропровода в эмалевой изол ции, 3-обмотка из микропровода в стекл нной изол ции, 4- токоподводы, 5- герметизирующее покрытие.The method is illustrated by a drawing (a resistor is made by the proposed method) where: 1 is a slotted frame, 2 is a microwire winding in enamel insulation, 3 is a microwire winding in glass insulation, 4 is current lead, 5 is a sealing coating.

За счет уменьшени  начального радиуса намотки вследствие применени  микропровода, начальный участок которого покрыт эмалевойBy reducing the initial winding radius due to the use of a microwire, the initial portion of which is covered with enamel
