Description

Известные способы поверки  корей машин посто нного тока основаны на принципе трансформаторной св зи испытуемого  кор  и электромагнита переменного тока.The known methods of checking korea of direct current machines are based on the principle of transformer coupling of the test core and an ac electromagnet.

По предлагаемому способу можно произвести практически все необходимые поверки  кор  при помощи одного прибора за одну установку  кор  в одной и той же схеме. Это достигаетс  подключением к соответствующим пластинам коллектора токовой цепи ваттметра и его цепи напр жени  параллельно катушке электромагнита, что упрощает поверку  корей и повышает производительность труда, так как ваттметр позвол ет определ ть не только величину напр жени , но и его фазу.According to the proposed method, it is possible to produce almost all the necessary checks of the core with the help of one device for one installation of the core in the same scheme. This is achieved by connecting the wattmeter current circuit and its voltage circuit parallel to the electromagnet coil to the appropriate collector plates, which simplifies the calibration of koreas and increases labor productivity, since the wattmeter allows determining not only the voltage, but also its phase.

На чертеже изображена схема поверки  корей по предлагаемому способу.The drawing shows the scheme of the calibration of Korea by the proposed method.

Поверка осуществл етс  с помощью электромагнита 1, прикладываемого к испытуемому  корю 2, двух щупов 3, подключаемых к соседним коллекторным пластинам 4, и ваттметра 5.;The verification is carried out using an electromagnet 1, applied to the test bark 2, two probes 3 connected to adjacent collector plates 4, and a wattmeter 5 .;

Обмотка электромагнита и цепь напр жени  ваттметра питаютс  переменным током повышенной частоты (200-800 3i{); к токовой цепи ваттметра чбрез трансформатор 6 подключаютс  щупы 5. По показани м ваттметра определ етс  наличие обрывов, замыканий, перекрещиваний и т. п.The electromagnet winding and the wattmeter voltage circuit are powered by alternating current of increased frequency (200-800 3i {); To the current circuit of the wattmeter, the transformer 6 is connected to the transducer 6. Based on the readings of the wattmeter, the presence of breaks, short circuits, crosses, etc. is determined.

Правильность укладки секций провер етс  при помощи стальной пластинки, котора  в этом случае прит гиваетс  к пазу при закорачивании щупов. В случае недостаточно четкого прит гивани  пластины (к малогабаритным  кор м) подключаетс  обмотка 7.The correct placement of the sections is checked with a steel plate, which in this case is attracted to the groove when shorting the probes. In the case of insufficiently clear attraction of the plate (to small-sized core), winding 7 is connected.
