Description

Пунктирными лини ми на фиг. 1 показано переменное магнитное поле дл  некоторого момента времени, созданное переменным током i, спошными лини ми - посто нное поле, созданное посто нным током iz.The dashed lines in FIG. Figure 1 shows an alternating magnetic field for a certain instant of time, created by alternating current i, with help lines — a constant field created by a direct current iz.

Токи tl и iz создают магнитные пол , которые в течение первого полупериода переменного тока tl в одном из сердечников имеют одинаковые, а в другом - противоположные направлени . Первый сердечник насыщаетс , а второй остаетс  ненасыщенный . Во втором полупериоде второй сердечник насыщаетс , первый остаетс  ненасыщенный . Вследствие нелинейного характера кривой намагничивани  сердечников магнитна  проницаемость сердечников уменьшаетс  и пропорционально уменьшаетс  индуктивность рабочих обмоток. Следовательно, изменением насыщени  сердечников с помощью подмагничивани  посто нным током можно в широких пределах измен ть индуктивность рабочих обмоток .The currents tl and iz create magnetic fields which, during the first half period of alternating current tl, have the same in one of the cores and opposite directions in the other. The first core is saturated, and the second remains unsaturated. In the second half period, the second core is saturated, the first remains unsaturated. Due to the nonlinear nature of the magnetization curve of the cores, the magnetic permeability of the cores decreases and the inductance of the working windings proportionally decreases. Consequently, by varying the saturation of the cores with the help of direct current magnetization, the inductance of the working windings can be varied over a wide range.

По рабочей обмотке одновременно протекает переменный и посто нный токи, следовательно , рабоча  обмотка выполн ет функции и обмотки управлени . Таким об694905AC and DC currents simultaneously flow through the working winding, therefore, the working winding performs the functions and control windings. So about 694905

разом, в одной обмотке совмещены две, благодар  чему имеет место в два раза меньший расход медного провода.at the same time, two are combined in one winding, so there is two times less consumption of copper wire.
