The application scenario that frequency ratio is higher, it is adaptable to low power electronic device；Silicon steel core is used mostly in power frequency equifrequent relatively low
Occasion, be suitable for electric power transformator and the reactor of relatively high power；And permalloy iron core is because pcrmeability is higher, conventional
In the device such as transformer and sensor.Non-crystaline amorphous metal and nanometer crystal alloy soft magnet core can be used in and use neck more widely
Territory.But the magnetic material of a kind of performance the most only shows single magnetic property, after making magnetic device, show single spy
Determine magnetic property or electrical property, it is impossible to show the comprehensive magnetic energy of multiple magnetic material.This is the essential performance of magnetic material
Determine.If using reactor to have high induction reactance when small area analysis at present in engineering, then this reactor is at big electric current
Time that magnetic material will be made to be in is saturated, and not there is suitable induction reactance；Otherwise, undersaturated reactor under big electric current, its sense
Anti-is the least.If but needing the reactor that both take into account in engineering, conventional prior art, material is with single magnetic material
The reactor that material iron core is made cannot realize.
Summary of the invention
Goal of the invention: the purpose of this utility model is to overcome deficiency of the prior art, it is provided that a kind of by two kinds or
The iron core " and connecing " of two or more different performances, makes the iron core of different magnetic property respectively constitute the magnetic circuit of oneself, at different ampere-turns
Under the effect of condition, show different effects respectively, thus than the inductance of original single magnetic core, there is more wide in range magnetic
The combined type non-crystaline amorphous metal soft magnet core of characteristic.
Technical scheme: in order to solve above-mentioned technical problem, a kind of combined type non-crystaline amorphous metal soft magnetism described in the utility model
Iron core, it includes at least one closed soft magnet core and at least one open type soft magnet core, described closed soft magnet core
Being non-crystaline amorphous metal soft magnet core with open type soft magnet core at least one of which, they are formed by stacking, and form composite structure,
The upper surface of described closed soft magnet core or lower surface are completely superposed with lower surface or the upper surface of open type soft magnet core.
The longitudinal section of described closed soft magnet core and open type soft magnet core is identical or different.
Described closed soft magnet core is different with the performance of open type soft magnet core.
Described closed soft magnet core and open type soft magnet core are non-crystaline amorphous metal soft magnet core, or non-crystaline amorphous metal soft magnet
Core and nanometer crystal alloy soft magnet core, silicon steel soft magnet core, ferroxcube magnetic core, permalloy soft magnet core, powder core
Combination.
Of the present utility model compound can be that the iron core of two kinds of different performances is combined, it is also possible to be three kinds, four kinds or more
The iron core of different performance is combined, but requires that each core configuration being combined must be consistent or close with size, precisely,
The length of magnetic path being exactly each magnetic core forming composite iron core to keep consistent with the shape of magnetic circuit, but each core section amasss
Can change within a large range, the sectional area of composite iron core is the summation that each single core section is long-pending.
Beneficial effect: compared with prior art, its remarkable advantage is this utility model: this utility model utilizes amorphous state to close
This characteristic of gold soft magnetic materials, can obtain the magnetic property of different qualities by different heat treatments；Again by different special
Property iron core compound, obtain combined type iron core.Compound, it is simply that by after the iron core " and connecing " of two or more different performance around
Coil, makes the iron core of different magnetic property respectively constitute the magnetic circuit of oneself, and these magnetic circuits is " and connecing ", in the peace of common coil
Under circle effect, when single magnetic circuit is saturated, another magnetic circuit in parallel therewith is the most saturated, the magnetic circuit of the most multiple parallel connections,
Under the effect of different ampere-turn conditions, show different effects respectively, thus have more than the inductance of original single magnetic core
Wide in range magnetic characteristic, it is possible to obtain and be more widely applied, meets more widely, complicated use requirement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is magnetic characteristic curve figure of the present utility model.
Detailed description of the invention
With embodiment, this utility model is further described below in conjunction with the accompanying drawings.
Embodiment 1:
As it is shown in figure 1, a kind of combined type non-crystaline amorphous metal soft magnet core described in the utility model, choosing relative permeability is
Amorphous alloy iron core and the amorphous otch iron core that equivalently-sized pcrmeability is 150 of 12000 are combined, the composite iron core tool obtained
There is comprehensive both the above iron core magnetic characteristic.During for making inductance, this inductance has big inductance value when having small area analysis；And work as
Inductance the most undersaturated characteristic during big electric current.
Embodiment 2:
As it is shown in figure 1, a kind of combined type non-crystaline amorphous metal soft magnet core described in the utility model, choosing relative permeability is
The amorphous otch iron core of 150 is combined with the Fe-Si-Al magnetic core that pcrmeability is 60, and the composite iron core obtained has at 150-
The overall magnetic characteristics of pcrmeability iron core between 60.In the case of larger current, magnetic device has adjustable inductance value range, with
Time there are the quality factor that comparison is high.
Following table is the composite iron core in embodiment 1 and single amorphous iron core performance comparison table:
Visible, composite iron core has broader working range, has high inductance value when low current, when big electric current,
Still there is certain inductance value；And contrast what iron core 1 was made up of single high magnetic permeability iron core, have very when small area analysis
Big inductance value, but when big electric current, owing to iron core is the most saturated, inductance value almost reduces to zero；And comparative example 2 is cut by single
Mouth iron core is made, and has certain inductance value when big electric current, and the inductance value when small area analysis is the lowest；Embodiment explanation by
Iron core after above two iron core is compound has the comprehensive magnetic energy more excellent than single iron core.
As in figure 2 it is shown, vertical coordinate is inductance value in figure, abscissa is current intensity.Curve 1 is the electricity of high permeability iron core
Relation between inductance value and electric current, during small area analysis, inductance value is higher, but is as the increase of electric current, and inductance curve declines quickly；
Under curve 2 is the relation between inductance value and the current intensity of otch iron core, and inductance value is relatively low, but inductance value increases with electric current
Drop slower；Curve 3 is the compound of above two iron core, shows and all has higher inductance value when high/low currents value.
This utility model provides a kind of thinking and method, and the method and the approach that implement this technical scheme are a lot, with
It is only preferred implementation of the present utility model described on, it is noted that for those skilled in the art,
On the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improvements and modifications also should regard
For protection domain of the present utility model, each ingredient the clearest and the most definite in the present embodiment all can use prior art to be realized.
