Description
Существующие измерительные трансформаторы посто нного тока с последовательным включением обмоток и выпр млением вспомогательного переменного тока твердыми выпр мител ми не обеспечивал ют точности измерений.The existing measuring transformers of direct current with the series connection of the windings and the rectification of the auxiliary alternating current with solid rectifiers did not ensure the accuracy of measurements.
Предлагаемый трансформатор вл етс более совершенным, так как в нем достигаетс повышение класса точности и линейности его рабочей характеристики, благодар применению донолнительной обмотки негативной св зи.The proposed transformer is more sophisticated, since it achieves an increase in the accuracy class and the linearity of its operating characteristic, thanks to the use of a negative-winding additional winding.
На чертеже изображена принципиальна схема предлагаемого трансформатора.The drawing shows a schematic diagram of the proposed transformer.
Трансформатор отличаетс от известных трансформаторов посто нного тока с последовательным включением первичных и вторичных обмоток тем, что в ием применена обмотка / негативной обратной св зи , через которую проходит выпр мленный вторичный ток. Обмотка / соедин етс так, что ампервитки, создаваемые током /2, вычитаютс из первичных ампервитков, создаваемь1х током /i.The transformer differs from the known DC transformers with a series connection of the primary and secondary windings in that the winding / negative feedback is applied, through which the rectified secondary current passes. The winding / is connected so that the current turns generated by the current / 2 are subtracted from the primary current turns generated by the current / i.
, Применение дополнительной обмотки / негативной обратной св зи обеспечивает значительное уменьшение погрешностей при том же качестве сердечника. Одновременно оно позвол ет использовать дл подобных трансформаторов сердечники нз невысококачественных дешевых материалов.The application of additional winding / negative feedback provides a significant reduction in errors with the same core quality. At the same time, it allows the use of cores of low-quality, low-quality materials for such transformers.
