Description

Известны способы определени  числа витков обмоток запоминающих магнитных сердечников с пр моугольной нетлей гистерезиса. Подобные снособы основаны на измерении коэффициента трансформации между двум  обмотками. Если известно точное число витков хот  бы в одной обмотке, то возможно определить число витков во всех остальных обмотках.Methods are known for determining the number of turns of the windings of magnetic memory cores with a rectangular net hysteresis. Such demolitions are based on measuring the transformation ratio between two windings. If the exact number of turns in at least one winding is known, then it is possible to determine the number of turns in all other windings.

В описываемом способе число витков обмоток в миниатюрных магнитных сердечниках быть определено независимо от того, известно ли число витков в других обмотках илп не известно. Способ основан на измерении времени перемагничивани  сердечника с пр моугольной петлей гистерезиса (ППГ) под воздействием импульсного перемагничивающего пол , созданного током, протекающим по испытуемой обмотке.In the described method, the number of turns of the windings in miniature magnetic cores should be determined regardless of whether the number of turns in the other windings of the ILT is known. The method is based on measuring the time of magnetization reversal of the core with a rectangular hysteresis loop (BCP) under the influence of a pulsed magnetization reversal field created by the current flowing through the test winding.

Принципиальна  схема устройства дл  измерени  по описываемому способу приведена на чертеже.A schematic diagram of a device for measuring by the described method is shown in the drawing.

Пр моугольные разнопол |зные импульсы тока равной амплитуды от генераторов / и 2 через согласующий трансформатор 3 и сопротивлени  4 VI 5 поступают в омботку 6 испытуемого трансформатора 7. Амплитуда тока контролируетс  с помощью вольтметра 8, включенного параллельно сопротивлению 5. Обмотка 9 присоединена к осциллографу 10.Square opposite current pulses of equal amplitude from generators / and 2 through matching transformer 3 and resistance 4 VI 5 are fed into test cell 6 of test transformer 7. The current amplitude is monitored using a voltmeter 8 connected in parallel to the resistance 5. Winding 9 is connected to an oscilloscope 10 .

Измер   с помощью осциллографа врем  церемагничивани  сердечника трансформатора 7, которое не зависит от числа витков обмотки 9, но зависит от числа витков обмотки 6, можно определить при заданной амнлитуде тока перемагничивани  точное число витков в обмотке 6. Зна  точное число витков в одной из обмоток трансформатора 7, определ ют известным способом измерени  коэффициента трансформации число витков во всех остальных обмотках трансформатора.Measuring with the oscilloscope the magnetization time of the transformer core 7, which does not depend on the number of windings of the winding 9, but depends on the number of windings of the winding 6, can be determined for a given amplitude of the magnetization reversal current of the winding 6. The exact number of turns in one of the windings of the transformer 7, determine the number of turns in all other transformer windings in a known way of measuring the transformation ratio.

Описанный способ измерени  числа витков запоминающего трансформатора на сердечнике с ППГ наиболее эффективен дл  маловитковых обмоток и может быть применен на предпри ти х и в лаборатори х , занимающихс  производством и испытани ми устройств вычислительной техники и цифровой автоматики.The described method of measuring the number of turns of a memory transformer on a core with a GTC is most effective for low-turn windings and can be applied in enterprises and laboratories engaged in the production and testing of computing devices and digital automation.

Предмет изобретени Subject invention

Способ определени  числа витков обмоток запоминающих магнитных сердечников с пр моугольной петлей гистерезиса, отличающийс  тем, что, с целью упрощени  измерени  и сохранени  необходимой точности, используют зависимость времени переключени  сердечника от тока перемагничивани , протекающего по обмотке, и поправку в числе витков определ ют по отклонению времени перемагничивани  от времени, соответствующего номинальному числу витков.The method of determining the number of turns of the windings of magnetic memory cores with a rectangular hysteresis loop, characterized in that, in order to simplify the measurement and maintain the required accuracy, the dependence of the core switching time on the magnetization reversal flowing through the winding and the correction in the number of turns are determined by the deviation reversal time from the time corresponding to the nominal number of turns.
