摘要

It is known that the magnetization in the orthogonal (transverse) to the working plane of the magnetic flux of the windings allows to change the magnetic properties of the ferromagnetic material. With this method, the bias in the working windings of the even harmonics does not occur, and the relative amplitudes of the odd harmonics decrease with increasing transverse field intensity, due to increased linearity magnetic characteristics of the magnetization. With increasing power controlled reactor or transformer transverse magnetization causes a reduction in loss and magnetostriction restriction hysteresis loop with a simultaneous increase its linearity. Technically, the transverse magnetization is implemented shift axes of the working (primary) and a winding bias (more) at an angle of 90 degrees, with a ferromagnet formed resulting magnetic field determined by the degree of exposure to the bias winding, and between the working and winding bias offline inductive (transformer) bond. Unlike the proposed solutions in the use of cross-magnetizing not only the internal magnetic yoke, but the total volume of the teeth; flow field winding located in the center of the magnetic core in the longitudinal axis thereof, closes the ends of the magnetic ferromagnetic plates form a complex step. The end plates have a diameter greater than the inner diameter of the yoke slots, and consist of layers of different diameter, in the repeating section of the magnetic circuit teeth zone that provides an increase in the volume of the magnetizing yoke and the magnetization efficiency.
