The present invention is a kind of transformer.
Existing transformer mainly is made of former, secondary side coil unshakable in one's determination and that be enclosed within on the core limb.When primary coil is connected AC power, in iron core, form the closed magnetic loop of a reciprocal alternation, by electromagnetic induction, obtain induced potential at secondary side coil.Because the transformer of this structure can only transmit an electromagnetic energy, so its core material consumption is many, utilance is low, iron loss is big, and the also corresponding increase of copper consumption is for high-power transformer, it is huge, heavy that volume seems, not only manufacturing cost height, and transportation difficulty.
Task of the present invention is to propose a kind of transformer by the quadrature field Design Theory, this transformer, with a transformer core material, use as two transformer cores,, improve the transformer core material utilance effectively to reach the design capacity that enlarges transformer significantly, reduce iron loss and copper consumption, reduced volume, weight reduction, purpose such as reduce cost.
The scheme that solves above-mentioned task is to change with the double orientation electrical steel sheet to become to make inside unshakable in one's determination to have the closed core of cavity, on iron core, placed former, the secondary side coil of two covers, wherein former, the secondary side coil of a cover is enclosed within on the core limb, another set of former, secondary side coil is placed in the inner cavity unshakable in one's determination, former, the secondary side coil of two covers is two circuit independently each other, two covers are former, the locus of secondary side coil, determine with the orthogonal magnetic field of generation after feeding alternating current in the coil.Like this, when feeding alternating current in two primary coils, just there are two orthogonal alternating magnetic fields to put on same soft magnetic bodies-be transformer fe in the heart, in iron core, produce the synthetic alternating magnetic field of a vector magnitude, according to electromagnetic induction principle, in two secondary side coils, will obtain induced potential simultaneously.
If be applied to amplitudes such as two alternating magnetic fields unshakable in one's determination are, same frequency, during same-phase, then the synthetic magnetic flux density in the iron core is that arbitrary alternating magnetic field is magnetized separately
Doubly, its magnetization configuration is reciprocal magnetization configuration.
If be applied to amplitudes such as two unshakable in one's determination alternating magnetic fields are, same frequency, and during 90 ° of phase phasic differences, then the synthetic magnetic flux density in the iron core equates with the independent magnetized magnetic flux density of arbitrary alternating magnetic field, and its magnetization configuration is the rotary magnetization form.
If being applied to two alternating magnetic fields unshakable in one's determination is same frequency, and phase place, when amplitude was all unequal, then the synthetic magnetic flux density in the iron core was between above-mentioned two kinds of situations.
The present invention is former with two covers, secondary side coil is placed on a tool transformer fe in the heart simultaneously, form two independent each other, irrelevant Circuits System of disturbing, can transmit electromagnetic energy separately simultaneously, thereby enlarge the design capacity of transformer significantly, improve the core material utilance effectively.With with capacity transformer, the present invention is few than the used core material of prior art, as core material with the consumption as much, then the present invention improves than the prior art capacity, so adopt the present invention correspondingly can reduced volume, weight reduction reduces iron loss, save core material and copper consumption, reduced cost.
