The invention discloses an energy-saving AC electromagnet for a valve. The energy-saving AC electromagnet for the valve comprises, by weight, 70%-78% of silicon steel on the uppermost layer, 18%-21% of soft magnetic material on the middle layer and 3%-10% of metal glass on the lowermost layer in a combined mode. The soft magnetic material includes soft magnetic ferrite. The energy-saving AC electromagnet for the valve has the advantages of being low in density, low in magnetic conductivity, low in Curie temperature, low in medium-high frequency loss and low in cost.
Description
Technical field
The present invention relates to a kind of energy-saving AC valve-control electromagnet.
Background technology
As far back as spring in 1820,
denmarkoersted once accidentally among just found this principle.1822, French physician
aragojust find with Gay-Lussac, when electric current passes through the coiling wherein having iron block, it can make the iron block in coiling magnetize.This is actually the initial discovery of electromagnet principle.1823,
sturgeon (unit of reluctance)have also been made once similar experiment: he is not around 18 circle copper bare wires on the U-shaped iron staff of bar magnet at one, when copper cash with
voltaic cellduring connection, namely create intensive magnetic field around the copper coil on U-shaped iron staff, so just make U-shaped iron staff become one piece " electromagnet ".Magnetic energy on this electromagnet amplifies many times than permanent magnetic, and it can pick up the iron block of heavier than it 20 times, and when after dump, and U-shaped iron staff with regard to what iron block is also inhaled incessantly, again becomes a common iron staff.
The electromagnet invention of sturgeon (unit of reluctance), makes people see handle
electric energybe converted into the bright outlook of magnetic energy, this invention is very fast to be spread some coastal states of Britain, the U.S. and West Europe.
1829, the U.S.
electricityfamily
henrysome innovations are carried out to sturgeon (unit of reluctance) electromagnet apparatus, has insulated with magnetoelectricity
wirereplace naked copper wire, therefore need not worry by copper conductor undue near and
short circuit.Because wire has had insulating barrier, just one can enclose the land tightly around together by them, because coil is more intensive, the magnetic field of generation is stronger, and so just substantially increasing electric energy conversion is the ability of magnetic energy.By 1831,
henrymanufactured experimently out one block of electromagnet upgraded, although its volume is also little, it can pick up the iron block of 1 ton of weight.
Summary of the invention

A kind of energy-saving AC valve-control electromagnet of the present invention, have density low, magnetic permeability is low, and Curie temperature is low, and medium-high frequency loss is low, the advantage that cost is low.
Embodiment
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Wherein, described energy-saving AC valve-control electromagnet comprises the silicon steel of the superiors, the soft magnetic material in intermediate layer and undermost metal glass and combines, described soft magnetic material comprises soft magnetic ferrite, described silicon steel accounts for the 70%-78% of the overall component of energy-saving AC valve-control electromagnet, described soft magnetic material accounts for the 18%-21% of the overall component of energy-saving AC valve-control electromagnet, described metal glass accounts for the 3%-10% of the overall component of energy-saving AC valve-control electromagnet, and described metal glass is Fe-based amorphous alloy.
Further illustrate, described silicon steel accounts for 70% of the overall component of energy-saving AC valve-control electromagnet, and described soft magnetic material accounts for 20% of the overall component of energy-saving AC valve-control electromagnet, and described metal glass accounts for 10% of the overall component of energy-saving AC valve-control electromagnet.
Further illustrating, its atom of this alloy of Fe-based amorphous alloy is in the non-crystal structure of random arrangement, makes it have narrow B-H loop, has high magnetic conductivity and low-loss feature; Simultaneously non-crystaline amorphous metal atomic arrangement irregular limits having free passage of electronics and causes resistivity to exceed 2-3 doubly than crystalline alloy, is so also conducive to reducing eddy current loss.Take non-crystaline amorphous metal as the transformer core that raw material is made, its no-load loss is compared with adopting the traditional transformer of silicon steel sheet, decrease about 75%, amorphous alloy transformer is made to have energy saving standard effect very significantly, when amorphous alloy transformer iron core is used for oil-immersed type transformer, can obviously reduce discharging multiple pernicious gas.So increasing production firm adopts non-crystaline amorphous metal to be used as the raw material of transformer core.The saturation flux density Bs of Fe-based amorphous alloy is lower than silicon steel, but under same Bm, 3% silicon steel that the loss ratio 0.23mm of Fe-based amorphous alloy is thick is little.Common people think that the little reason of loss is that iron-based amorphous alloy ribbon material thickness is thin, and resistivity is high.This is an aspect, and more chief reason is Fe-based amorphous alloy is amorphous state, and atomic arrangement is random, there is not the magnetocrystalline anisotropy that atom aligns generation, also there is not the grain boundary producing local deformation and chemistry offset.Therefore, hinder the energy barrier of domain wall motion and magnetic moments rotations very little, have unprecedented soft magnetism, so magnetic permeability is high, coercive force is little, and loss is low.Be characterized in that saturation magnetization is high, cheap, good processability; But its resistivity is low, eddy current loss is large under alternating magnetic field, be only suitable for static to use down, as manufacture electromagnetic core, pole shoe,
relaywith loud speaker magnetic conductor,
magnetic screencover etc.
Further illustrating, soft magnetic ferrite iron content 6% ~ 16%, there is good soft magnet performance, magnetic permeability and resistivity high, hardness is high, resistance to wear good, but property is crisp, mainly for the manufacture of miniature transformer,
magnetic amplifier, the iron core of relay etc. and magnetic head, ultrasonic transducer etc.The invention provides a kind of energy-saving AC valve-control electromagnet, have density low, magnetic permeability is low, and Curie temperature is low, and medium-high frequency loss is low, the advantage that cost is low.
The specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention, and the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection range that protection scope of the present invention should limit with claims is as the criterion.
