Description
Насто щее изобретение отиоситс к способам злучшени коммутации электрических лгашии, осуществл емым иутем иодпитки обмоткн дополнительных полюсов машины от независимого источника.The present invention is rationalized to the ways of improper commutation of electric terminals, carried out and in the form of an iodopitka winding additional poles of the machine from an independent source.
Предлагаемый способ отличаетс от пзвестных тем. что подпитку производ т током, опережающим переменную составл ющую тока маши11Ы , что обеспечивает компенсапию переменной составл ющей реактивной 3. д. с.The proposed method differs from the known topics. that the make-up is produced by a current ahead of the variable component of the current of the machine, which provides compensation for the variable component of the reactive 3. d.
На чертеже изображена схема подпитки по предлагаемому способу.The drawing shows the scheme of feeding on the proposed method.
Обмотка / дополнительных полюсов электрической машины включена последовательно .в цепь кор 2 и обмотки возбуждени 3 и одновременно подпитываетс от -постороннего источника 4 переменного тока. Источник 4 создает ток такой же частоты, что и частота переменной составл ющей тока двигател , но сдвинутый по фазе относительно нее на угол около 90° в сторону опережепи .The winding / additional poles of an electric machine are connected in series to the circuit 2 and the excitation winding 3 and at the same time fed from an off-side source of alternating current 4. Source 4 generates a current of the same frequency as the frequency of the variable component of the motor current, but shifted in phase relative to it by an angle of about 90 ° towards the front side.
Необходима величина тока подпитки может быть установлена в каждом конкретном случае при испытании. При мен ющейс нагрузке двигателей должно быть обеспечено автоматическое измененпе тока подпитки.The required amount of current make-up can be set in each case during the test. When changing the load of the motors, automatic charging current should be ensured.
Этот способ главным образом предпазпачен дл т говых двигателей посто нного тока, питаемых от выпр мителей.This method is mainly pre-used for direct current traction motors powered by rectifiers.
Предмет изобретени Subject invention
Способ улучщени коммутации электрических мащин (например т товых двигателей посто нного тока, питаемых от выпр мителей), осуществл емый путем подпитки обмотки дополнительных полюсов машины от независимого источника, о т л и ч а ю и; ий с тем, что, с целью компенсации переменной составл ющей реактивной э. д. с., подпитку пропзвод т током, опережающим переменную составл ющую тока мащины.A method for improving the commutation of electrical masks (for example, commanding DC motors powered by rectifiers), carried out by feeding the winding of the additional poles of the machine from an independent source into one; so that, in order to compensate for the variable component of the reactive e. d. s., the make-up is made with a current leading the variable component of the maschine current.
