Summary of the invention
The main technical problem to be solved in the present invention is: the transformer device structure that a kind of leakage-adjustable inductance is provided, it can will be finished via coiling, iron core is assembled the transformer after fixing, and adjusts the mechanism of leakage inductance again, and the leakage inductance distribution scenario of this transformer finished product is improved.
Technical solution of the present invention is: a kind of transformer of leakage-adjustable inductance, and described transformer comprises:
Drum stand has hollow bulb, and is distinguished into first winding section and second winding section of twining for coil in lateral margin;
Iron core group, being bonded with each other stretches through is contained in the drum stand hollow bulb, constitutes main magnetic circuit; And
Magnetic conductive component, have with described coil between relative free displacement one distance, use the adjustment leakage inductance.
The transformer of aforesaid leakage-adjustable inductance, at least one portion that stretches through in the described iron core group with the drum stand hollow bulb that can stretch through.
The transformer of aforesaid leakage-adjustable inductance, described magnetic conductive component have more the magnetic conduction adjustment part and are positioned on described drum stand or the iron core group, for the activity displacement that stretches through of described magnetic conductive component.
Characteristics of the present invention and advantage are: the transformer device structure of leakage-adjustable inductance proposed by the invention, by said structure, can be after coiling be finished, by changing the distance of magnetic conductive component and coil windings, make the leakage inductance of this transformer finished product obtain to adjust mechanism, the leakage inductance distribution scenario of this transformer finished product is improved thus, thereby has overcome the defective of prior art, can adjust leakage inductance as required, effectively revise the leakage inductance variable quantity.

Embodiment
Be to make the convenient effect of understanding content of the present invention and reaching of your auditor, conjunction with figs. and specific embodiment now, introduction is described as follows in detail:
The transformer of the leakage-adjustable inductance that the present invention proposes, it is mainly used in needs in the change of current of the leakage inductance characteristic module, transformer of the present invention is now lifted a specific embodiment (seeing also shown in Fig. 2,3), it is mainly by drum stand 2, iron core group 3 and magnetic conductive component 5, and this magnetic conduction is adjusted element 5 and 2 of drum stands are provided with magnetic conduction adjustment part 4; Wherein:
This drum stand 2, has hollow bulb 21, and between lateral margin, be provided with the window 22 that winds the line at interval, to be distinguished into first winding section 221 and second winding section 222, can to supply first side winding coil and secondary side winding coil winding zone respectively, and stretch wall 23 in both sides formation side, for magnetic conduction adjustment part 4 overlap joints, and be provided with in two ends lead terminal 24 as with being connected of external circuit, wherein in the present embodiment the first side winding coil is defined as magnetizing coil 25, the secondary side winding coil is defined as induction coil 26.
This iron core group 3 is made up of first iron core 31 and second iron core 32, and wherein this second iron core 32 stretches through and is contained in drum stand 2 hollow bulbs 21, makes first iron core 31 and the second iron core 32 formation magnetic circuit that mutually combines.
This magnetic conduction adjustment part 4, has movable guide cavity 41 in it, and in both sides the side of corresponding respectively drum stand 2 is stretched wall 23 and is provided with overlap joint rib 42, to stretch wall 23 by these overlap joint rib 42 joining sides, this magnetic conduction adjustment part 4 is positioned on the drum stand 2, can use the leakage magnetic flux of adjusting with the drum stand winding for the stretch through displacement of activity of magnetic conductive component 5 in this activity guide cavity 41, it is as follows now to sketch this adjustment mode:
As shown in Figure 4, wherein A is the moving direction of magnetic conductive component 5, B is a leakage magnetic flux, by set up the axis direction of magnetic conductive component 5 along the drum stand hollow bulb move one with respect to the horizontal displacement of magnetizing coil 25 and induction coil 26 apart from d1, wherein when shift length d1 is big more, because this magnetic conductive component 5 is gradually away from magnetizing coil 25, the part leakage magnetic flux of induction coil 26 will be reduced relatively (otherwise direction then increases relatively), use the mechanism that forms by magnetic conductive component 5 change part leakage magnetic flux, and then reach the purpose of adjusting leakage inductance.
Moreover, magnetic conductive component 5 of the present invention can combine (as shown in Figure 5) by other direction with drum stand, wherein by setting up magnetic conductive component 5, form another shift length d2 vertical with the axis direction of drum stand hollow bulb, in an embodiment as the shift length d2 of magnetic conductive component 5 during near coil 25,26, promptly increase the part leakage magnetic flux, otherwise if when the time away from coil 25,26, then will reduce the part leakage magnetic flux, so can be adjusted to required leakage inductance value on demand, make the leakage inductance distribution tool of this transformer finished product adjust mechanism.
Though the present invention discloses with specific embodiment; but it is not in order to limit the present invention's (not being restricted to level or vertical plane as the displacement angle of adjusting); any those skilled in the art; the displacement of the equivalent assemblies of under the prerequisite that does not break away from design of the present invention and scope, having done; or, all should still belong to the category that this patent is contained according to equivalent variations and modification that scope of patent protection of the present invention is done.
