Description

Известны способы определени  короткозамкнутых витков в обмотках высокочувствительного магнитного усилител  путем подачи напр жени  переменного тока на рабочую обмотку, расположенную на одном из сердечников усилител . Однако такие способы недостаточно точны.Methods are known for determining short-circuited coils in the windings of a highly sensitive magnetic amplifier by applying an alternating current voltage to the working winding located on one of the amplifier cores. However, such methods are not accurate enough.

В описываемом способе дл  повышени  точности определени  исключаетс  вли ние межвитковой емкости обмоток, а наличие короткозамкнутых витков определ ют по сохранению пол рности выпр мленного напр жени  на рабочей обмотке, расположенной на другом сердечнике , при замыкании накоротко витка, введенного в окно магнитопровода усилител .In the described method, to improve the accuracy of the determination, the influence of the inter-turn capacitance of the windings is excluded, and the presence of short-circuited coils is determined by maintaining the polarity of the rectified voltage on the working coil located on another core when the coil of the amplifier is closed.

На чертеже изображена схема устройства, примен емого дл  осуществлени  способа.The drawing shows a diagram of the device used to implement the method.

Способ определени  короткозамкнутых витков состоит в том, что к одной из рабочих обмоток 1 магнитного усилител  2 подвод  г напр жение переменного тока, создающее в сердечнике 3 индукцию равную рабочей или несколько меньшую. При этом напр жение на обмотке 4 переменного тока другого сердечника 5 измер ют при помощи магнитоэлектрического прибора 6 посредством фазочувствительного выпр мител  7. Затем в окно магнитопровода ввод т замыкаемый накоротко виток или охватывают таким проводником общую катущку если в усилителе применены сердечники стержневого типа.The method of determining short-circuited coils is that one of the working windings 1 of the magnetic amplifier 2 is supplied with an alternating current voltage, which creates in the core 3 an induction equal to or slightly less. At the same time, the voltage on the alternating current winding 4 of another core 5 is measured using a magnetoelectric device 6 by means of a phase-sensitive rectifier 7. Then a lockable coil is inserted into the window of the magnetic core or a common coil is used with such a conductor if core-type cores are used.

Изменение пол рности измер емого напр жени  свидетельствует об отсутствии короткозамкнутых витков. Если же в общей обмотке 8 имеютс  короткозамкнутые витки, то это приводит к сильной индуктивной св зи между сердечниками 5 и 5, г следовательно, к индуктивной перекомпенсации емкостного сдвига. В этом случае пол рность напр жени  измер ема  прибором 6, остаетс  посто нной. A change in the polarity of the measured voltage indicates the absence of short-circuited turns. If in the common winding 8 there are short-circuited coils, this leads to a strong inductive connection between the cores 5 and 5, g, therefore, to inductive overcompensation of capacitive shear. In this case, the polarity of the voltage measured by the device 6 remains constant.
