Operation principle of the present invention: AC Windings is sealed in ac circuit, when alternating current is I
1When flowing through, in magnetic circuit, will there be the main flux φ that produces by the first AC Windings 2-1
1And the main flux φ that produces by the second AC Windings 2-2
2When the main flux that produces does not flow electric current at the control winding, separately respectively by four closed magnetic circuits; AC Windings produces and its number of turn and the corresponding inductance of magnetic circuit magnetic resistance, and the core portion that is wound with the control winding becomes control magnetic flux φ
cCommon magnetic circuit with main flux.At AC Windings stream electric current I is arranged
1State under, if control winding flow through Control current I
c, on the control winding, will produce umber of turn and Control current I
cThe magnetomotive force of product, control magnetic flux φ
cWith main flux φ
1, φ
2The magnetic secret meeting of equidirectional common magnetic circuit part increases, and magnetic permeability changes, the main flux Be Controlled, and inductance reduces.If continue to increase the electric current I in the AC Windings
1Or Control current I
c, the common magnetic circuit state that will reach capacity and since the first AC Windings 2-1 and the second AC Windings 2-2 around to opposite, the two direction that produces magnetic flux is opposite, so the main flux φ that has increased
1With φ
2Cancel out each other, it is saturated fully that magnetic circuit can not reach, and magnetic password protection unshakable in one's determination is held on the certain numerical value.The increase that the first AC Windings 2-1 and the second AC Windings 2-2 produce main flux does not partly circulate in closed magnetic circuit, and promptly the magnetomotive force of AC Windings is cancelled out each other.Increase the AC Windings electric current I howsoever
1, because close the remaining on the certain numerical value of magnetic of common magnetic circuit, the magnetic flux that the magnetic flux that the first AC Windings 2-1 increases and the second AC Windings 2-2 increase is cancelled out each other, and therefore, still can control main flux by regulating Control current, makes reactor adjustable.And, therefore can suppress the higher harmonic current in the AC Windings because the common magnetic circuit of control reactor can not reach saturated fully.Owing to stream in control winding or the harmonic wave inhibition winding has the alternating current of current first harmonics even-multiple number of times in the AC Windings, can further suppress the higher harmonic current in the AC Windings in addition.
