Abstract
The invention relates to a high-power high-frequency transformer with high frequency and low eddy-current loss. The high-power high-frequency transformer comprises a high-frequency transformer, wherein the iron core in the high-frequency transformer adopts a ferrite core; the ferrite core is formed by sticking multiple ferrites; and the coils in the high-frequency transformer adopt ion lines. The high-power high-frequency transformer provided by the invention has the advantages that: the high-frequency transformer can realize high-frequency operation with the frequency of 50-100kHZ; lead loss is very low; and the eddy-current loss generated by the magnetic flux leakage can be tremendously reduced.
Description
Technical field
The present invention relates to a kind of high-power high-frequency transformer that a kind of frequency is high, eddy current loss is low, be mainly used in dust removing transformer, belong to high frequency transformer and manufacture field.
Background technology
CN 201340791Y, title " high frequency transformer ", comprise cylindrical shell, cylindrical shell middle device has hollow copper rod, hollow copper rod is fastened on cylindrical shell by water supply connector, the outer wall of cylindrical shell is provided with binding post, hollow copper rod upper unit has water out adapter, ferrite magnetic material is installed in cylindrical shell and is placed on hollow copper rod, wire spiral surrounding is on ferrite magnetic material, cooling water pipe and wire are staggered to be looped around on ferrite magnetic material side by side, one end of cooling water pipe is connected with water out adapter, and the other end of cooling water pipe leads to cylindrical shell outside.
CN2497407Y, title " Combined transformer iron-core ", piled up and constituted by some magnetic ferrites fritter magnetic cores.Utilize some fritter magnetic cores to pile up the iron core that constitutes large volume, solved the problem that magnetic ferrites can not direct sintering produce large volume iron core.
CN101859631A, title " amorphous alloy iron core of medium-high frequency electrostatic ", comprise high-tension coil pour mass, low-voltage coil pour mass, be arranged on the iron core of low-voltage coil pour mass inner side, described iron core comprises upper core and lower core, on, between lower core, there is cutting joint, be connected to the insulator on high-tension coil pour mass, and fixing high, low-voltage coil pour mass upper, single-phase transformer that lower clamping piece forms, between high-tension coil pour mass and upper clamping piece, be equipped with cushion block, between high-tension coil pour mass and lower clamping piece, be equipped with lower cushion block, lower clamping piece bottom connects supporting plate and base, it is characterized in that described on, cutting joint between lower core is double inclined plane V font cutting joint.
The weak point that above-mentioned background technology exists: the one, be not suitable under 50-100KHZ frequency and work; The 2nd, the eddy current loss that magnetic leakage produces is large.
Summary of the invention
Purpose of design: avoid the weak point in background technology, design a kind of high-power high-frequency transformer that a kind of frequency is high, eddy current loss is low.
Design: in order to realize above-mentioned purpose of design.1, the application adopts high-frequency soft magnetic material as magnetic circuit, is one of technical characterictic of the present invention.The object of doing is like this: very large due to what ferrite volume can not be done at present, therefore high-power high-frequency transformer manufacture is just had any problem, the application adopts little magnetic patch splicing process, so just can manufacture the iron core of significant volume, for high frequency becomes the high-power possibility that development is provided, frequency can be used on 50～100kHZ.2, coil adopts the design of ion line, is two of technical characterictic of the present invention.The object of doing is like this: the one, because frequency is between 50～100kHZ, wire loss is very low, therefore ion line solid conductor can be very thin, generally≤φ 0.1mm, outsourcing paint film, between wire, there is good insulation, a wire is to have the such wire of a lot of roots to combine to reach needed cross section, and every wire is in continuous transposition, in magnetic field, the length and location of wire is of living in the same, therefore the electric current of every wire is even, and kelvin effect is can not produce very large loss in this case; The 2nd, because every cross section of wire is very little, so eddy current loss is also very little, because high frequency transformer leakage flux frequency is high too, so can not produce very lossy on fuel tank and structural member; The 3rd, due to this high frequency transformer, all structural members all adopt non-magnetic material, have reduced so especially the eddy current loss that leakage field produces.3, the sleeve pipe that is positioned at high frequency transformer lower end adopts the design of 8 grades, is three of technical characterictic of the present invention.The object of doing is like this: the length forming due to 8 grades of sleeve pipes reaches 260mm, so creepage distance is long, can not cause puncturing of transformer.
Technical scheme: a kind of high-power high-frequency transformer, it comprises high frequency transformer, the iron core in described high frequency transformer adopts ferrite core and ferrite core to consist of polylith ferrite tack; Described high frequency transformer coil adopts ion line.
The present invention compares with background technology, and the one, realized high frequency transformer frequency high-frequency work between 50～100kHZ; The 2nd, wire loss is very low; The 3rd, greatly reduced the eddy current loss that leakage field produces.
Accompanying drawing explanation
Fig. 1 is the structural representation of high-power high-frequency transformer.
