Abstract
The invention discloses a winding type filter inductor. The winding type filter inductor comprises multiple layers of coils, and is characterized in that a spacing layer is arranged between every two layers of coils and flatly wraps the layer of coil in the spacing layer. According to the winding type filter inductor, when multiple layers of coils with the same turns are wound, each layer of coil is kept flat by winding an insulating layer on each layer of coil, leakage inductance is reduced, and the filter effect of the filter inductor is better.
Description
Technical field
The present invention relates to a kind of Wound-rotor type filter inductance, belong to electronic technology field.
Background technology
As far as desirable inductance, when coil after intact, all magnetic fluxs all concentrate on coil in intracardiac.But generally loop coil can be around a full week, or coiling is not tight, can cause leakage of magnetic flux like this.Leakage inductance is more little good more generally speaking, and the energy of the big more transmission of leakage inductance can reduce with the increase of leakage inductance, is prone to magnetic saturation takes place, and makes the filter effect variation.
Summary of the invention
Technical problem to be solved by this invention provides a kind of Wound-rotor type filter inductance, makes its leakage inductance littler, and filter effect is better.
For solving the problems of the technologies described above, the present invention provides a kind of Wound-rotor type filter inductance, comprises the multilayer pitch of the laps that is wrapped on the skeleton, it is characterized in that, between each layer line circle, wall is set, and is by said wall that one deck coil parcel that wraps up in it is smooth.
Said wall is an insulating barrier.
The insulating tape of said wall for twining.
The beneficial effect that the present invention reached:
Wound-rotor type filter inductance of the present invention when coiling multilayer inductor coil, through between each layer line circle, twining insulating barrier, makes every layer line circle keep smooth, has reduced leakage inductance, makes the filter effect of filter inductance better.
Description of drawings
Fig. 1 is a sketch map of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
As shown in Figure 1, Wound-rotor type filter inductance of the present invention when coiling multilayer inductor coil, through between each layer 1,2 coil, twining a wall 3 tightly, makes every layer line circle keep smooth, has reduced leakage inductance, makes the filter effect of filter inductance better.
What the wall that twines 3 was preferable is insulating tape.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and distortion, these improvement and distortion also should be regarded as protection scope of the present invention.
Claims (3)
