Abstract:
(EN)
The invention relates to reverse transformers configured on several ferromagnetic cores divided by an air gap. A magnetizing winding is configured on only one or a part of the cores, forming a magnetizing inductor. When a current is supplied to the magnetizing winding, the ferromagnetic core of the inductor is magnetized, as are the neighbouring cores via the air gap. The air gap is selected so that a significant part of the magnetic field of the cores is closed across the air, forming a secondary magnetic leakage field. Part of the magnetic field of all the cores is closed across the magnetic circuit via the air gap, forming a common magnetic circuit and a common magnetic flux. The magnetic leakage field of the cores is closed outside the inductor and does not play a part in the magnetic interaction of said components, nor does it form a common magnetic flux linkage with the magnetizing winding of the inductor. Thus, it does not affect the establishment of a current in the inductor winding because it does not generate emf against the current during magnetization. The windings of the secondary cores encompass the entire magnetic field thereof and serve merely to convert all the secondary magnetic leakage fluxes into electrical energy during demagnetization. This results in a more complete conversion of all the magnetic energy in the structure into electrical energy.

L'invention concerne des transformateurs inverses comportant plusieurs noyaux ferromagnétiques séparés par un entrefer. Un enroulement d'aimantation est réalisé uniquement sur un ou plusieurs noyaux pour former une inductance d'aimantation. Lorsque l'on fournit un courant d'aimantation au noyau ferromagnétique, on effectue l'aimantation dudit noyau et, à travers l'entrefer, des noyaux adjacents. L'entrefer est choisi de telle sorte qu'une partie substantielle du champ magnétique des noyaux forme une boucle dans l'air formant un champ magnétique secondaire de dispersion. Une partie du champ magnétique des noyaux du circuit magnétique forme une boucle via l'entrefer de manière à former un circuit magnétique et un flux magnétique communs. Le champ magnétique de dispersion forme une boucle à l'extérieur de l'inducteur du noyau et ne participe pas à leur interaction magnétique ni ne forme aucune liaison de flux avec l'inductance d'aimantation, et n'empêche pas l'apparition du courant dans la bobine de l'inducteur car ne crée aucune FEM à contre-courant lors de l'aimantation. Les enroulements secondaires couvrent l'ensemble de leur champ magnétique, y compris le champ magnétique de dispersion, et ne servent qu'à convertir tous les flux magnétiques secondaires en énergie électrique lors de la désaimantation. On obtient ainsi une transformation plus complète de l'énergie magnétique en énergie électrique.
(RU)
Изобретение относится к обратноходовым трансформаторам, выполненным на нескольких ферромагнитных сердечниках, разделенных воздушным зазором. Обмотка намагничивания выполнена только на одном или части сердечников, образуя намагничивающий индуктор. При подаче тока в его намагничивающую обмотку намагничивается его ферромагнитный сердечник и через воздушный зазор - соседние сердечники. Воздушный зазор подбирается таким, чтобы значительная часть магнитного поля сердечников замыкалась по воздуху, образуя вторичное магнитное поле рассеивания. Часть магнитного поля всех сердечников замкнута по магнитной цепи через воздушный зазор, образуя общую магнитную цепь, общий магнитный поток. Магнитное поле рассеяния сердечников замкнуто вне индуктора и не участвует в их магнитном взаимодействии, не образует общего потокосцепления с намагничивающей обмоткой индуктора. Поэтому не влияет на установление тока в обмотке индуктора, так как не создает э.д.с. против тока при намагничивании. Обмотки вторичных сердечников охватывают все их магнитное поле, включая магнитное поле рассеяния, и служат лишь для преобразования всех вторичных магнитных потоков рассеяния в электроэнергию при размагничивании. Этим достигается более полное преобразование всей магнитной энергии системы в электроэнергию.
