Abstract
The utility model discloses a kind of demagnetization transformers, belong to transformer technology field, and for eliminating the magnetic field on object, the demagnetization transformer includes iron core and coil；It is characterized by: iron core is port type iron core, the disconnected band that a width is constant d is opened up in a side of the port type iron core, which is demagnetization channel；Coil is two, and two coils behind demagnetization channel by being socketed on two fractures of port type iron core.The stupefied place in the side of two fractures is provided with 45 degree of chamfering；Two coils are respectively equipped with three pairs of lead-out wires.By using above-mentioned technical proposal, when use, object will be eliminated first as in demagnetization channel, different erasing fields is then generated by different connection types, by adjusting the size in magnetic field, so that at the wound core neutral gear of field homogeneity, i.e. at demagnetization channel, the purpose of demagnetization is realized by destroying magnetic moment arrangement in material in the magnetic field, that is, realizes and carry out demagnetization to different objects.
Description
Technical field
The utility model belongs to transformer technology field more particularly to a kind of demagnetization transformer.
Background technique
Transformer (Transformer) is the device for changing alternating voltage using the principle of electromagnetic induction, main member
It is primary coil, secondary coil and iron core (magnetic core).Major function has: voltage transformation, impedance transformation, is isolated, is steady at current transformation
Press (magnetic saturation transformer) etc..Can be divided into, according to use: (electric furnace becomes, rectification becomes, power frequency examination for power transformer and special transformer
Test transformer, pressure regulator, mining change, audio-frequency transformer, intermediate-frequency transformer, high frequency transformer, impact transformer, instrument transformation
Device, electronic transformer, reactor, mutual inductor etc.).Circuit symbol often uses T as beginning of number: T01, T201 etc..
It is well known that magnetization refer under the action of by magnetic field, due in material magnetic moment arrange when orientation reach unanimity and
Show certain magnetic phenomenon.Make do not have the process that magnetic substance obtains magnetism originally.Some objects in magnet or
Magnetism can be shown under the action of electric current, this phenomenon is called magnetization；However in practical work, need to eliminate on Magnetized Material
Magnetic field, for this purpose, designing and developing a kind of demagnetization transformer that can eliminate magnetic field on Magnetized Material seems it is particularly important.
Utility model content
In view of the drawbacks of the prior art, the utility model provides a kind of demagnetization transformer, the demagnetization transformer by adjusting
The magnetic field strength of coil, and then eliminate the magnetic field in Magnetized Material.
Used by the utility model the specific technical proposal is:
The goal of the invention of this patent is to provide a kind of demagnetization transformer, for eliminating the magnetic field on object, the demagnetization
Transformer includes iron core (1) and coil (2)；The iron core (1) is port type iron core, is opened in a side of the port type iron core
If the disconnected band that a width is constant d, which is demagnetization channel (3)；The coil (2) is two, and two coils (2) are logical
It is socketed on two fractures of port type iron core after crossing demagnetization channel (3)；The stupefied place in the side of described two fractures is provided with 45 degree
Chamfering；Above-mentioned two coil (2) is respectively equipped with three pairs of lead-out wires.
The advantages of the utility model and good effect are as follows:
By using above-mentioned technical proposal, the utility model is had the following technical effect that:
The working principle of the utility model is, in use, will eliminate object first as in demagnetization channel, then to pass through not
Same connection type generates different erasing fields, by adjusting the size in magnetic field, so that the wound core neutral gear of field homogeneity
Place, i.e., at demagnetization channel, which realizes the purpose of demagnetization by destroying magnetic moment arrangement in material, that is, realizes to difference
Object carry out demagnetization.
Detailed description of the invention
Fig. 1 is the structure chart of utility model preferred embodiment；
Fig. 2 is the structure chart of iron core in utility model preferred embodiment；
Wherein: 1, iron core；2, coil；3, demagnetization channel；4, lug boss.
Specific embodiment
For the invention, features and effects that can further appreciate that the utility model, the following examples are hereby given, and cooperates
Detailed description are as follows for attached drawing.
The structure of the utility model is explained in detail with reference to the accompanying drawing.
Please refer to Fig. 1 and Fig. 2: a kind of demagnetization transformer, for eliminating the magnetic field on object, the demagnetization transformer packet
Include iron core 1 and coil 2；The iron core 1 is port type iron core, and it is normal for opening up a width in a side of the port type iron core
The disconnected band of number d, which is demagnetization channel 3；The coil 2 is two, and two coils 2 behind demagnetization channel 3 by being socketed on
On two fractures of port type iron core；The stupefied place in the side of described two fractures is provided with 45 degree of chamfering；Above-mentioned two coil 2 is distinguished
Equipped with three pairs of lead-out wires；Different erasing fields is generated by different connection types, and different objects is carried out with realizing
Demagnetization.
In above preferred embodiment, iron core 1 uses 0.23 or 0.35 material, simultaneously as above-mentioned preferred implementation
Example has done 45 degree of corner cut at the iron core opening wide place of tongue, enables to demagnetization transformer when being powered generation magnetic field, magnetic field can be more
Add at uniform wound core neutral gear, reduces magnetic flux resistance, efficiently increase demagnetization function.
Loop construction in above preferred embodiment can be divided into series connection around the home according to design magnetic flux and be in parallel around the home, and convert
The connection type of left and right coil can reach different erasure effects.
In above preferred embodiment, port type iron core opening forms spill, is respectively charged into coil in iron core opening two sides,
It is allowed to generate magnetic field, realizes demagnetization, and without remanent magnetism after power-off.
In use, object will be eliminated first as in demagnetization channel, then generated by different connection types different
Erasing field, by adjusting the size in magnetic field, so that at the wound core neutral gear of field homogeneity, i.e., at demagnetization channel, the magnetic field
It by destroying magnetic moment arrangement in material, and then realizes the purpose of demagnetization, that is, realizes and demagnetization is carried out to different objects.
The above is only the preferred embodiment to the utility model, is not made in any form to the utility model
Limitation, it is all according to the technical essence of the utility model any simple modification made to the above embodiment, equivalent variations with
Modification, is all within the scope of the technical scheme of the utility model.
