Description
The present invention relates to a kind of transformer of magnetic material protection box double as low pressure winding, be used for the transformation of inverter type welder and all kinds of Switching Power Supplies.
The transformation of inverter type welder and all kinds of Switching Power Supplies; adopt traditional transformer; volume is quite huge; not only consume a large amount of coilings, and it is bad to dispel the heat, it is bad to insulate; adopt amorphous magnetic material to make iron core for this reason; but make the transformer of protecting box double as low pressure winding with electric conducting material, as patent No. 95229317.X, disclosed technology; it is little that it has a compact conformation volume; in light weight, CURRENT DISTRIBUTION is even, advantage; but because the making of protection box is convenient inadequately; processing is complicated, causes productivity ratio low, and product quality is wayward.
Transformer mainly is made of iron core, elementary winding and secondary winding.Usually mainly be that elementary winding then has number of ampere turns to equate with secondary winding by the exciting current that just is provided at generation magnetic field in the iron core around winding, the operating current that direction is opposite passes through.Should offset fully for desirable transformer, magnetic field elementary and that the secondary work electric current produces.In the real transformer this part magnetic field cancellation bad be the main part of transformer leakage reactance because the general work electric current is than the big several magnitude of exciting current, it has very big influence to the performance of transformer, in particular for the high frequency transformer of field of power electronics.
Conventional power transformer is because its operating frequency very low (50 or 60HZ), generally adopts elementary winding and secondary winding one an interior outer layering coiling.And the winding method that high frequency transformer can adopt elementary and secondary multilayer to intermesh for the minimizing leakage reactance, but this method exists elementary and secondary winding insulation difficulty and the too big shortcoming of parasitic capacitance, and complex process, be not easy to the mass industrial production.
People's thin copper belt commonly used rolls winding and produces high frequency transformer in recent years, and owing to structural reason, this winding generally can only be used for open cores such as E type C type.Can make the iron core performance depreciation for magnetic amorphous attitude magnetic material opening, and be optimum from iron core performance perspective annular.
The objective of the invention is to overcome the shortcoming and deficiency of above-mentioned existing branch art, and provide a kind of manufacture method simple, the magnetic material protection box of handling ease, the transformer of double as low pressure winding, thus can improve the quality of products greatly, boost productivity.
The present invention proposes for overcoming above technical barrier, and its main feature is:
1, make full use of magnetic materials such as amorphous and ultracrystallite and be full of the high characteristics of magnetic flux, and the iron core that further adopts larger cross-section reduces to minimum with the low pressure winding of transformer.
2, replace metals (patent 94245529.0) such as traditional plastics and aluminium to use the protection box of sheet copper system, make it not only have support, the effect of protection and heat radiation, and the double low pressure winding of doing with magnetic material.
3, close around the high pressure winding outside box, there is good lotus root to close with the low pressure winding.
4, transformer compact overall structure, volume is little, and is in light weight, is particularly suited for the mass industrial production.
The objective of the invention is to realize by following technical proposal:
A kind of transformer of magnetic material protection box double as low pressure winding; comprise the magnetic amorphous iron core; the protection box that electric conducting material is made; double as low pressure winding; the high pressure winding; cylinder manifold; support base plate etc.; the protection box that it is characterized in that double as low pressure winding is made up of lower box body 8 and upper box cover 2; lower box body 8 is the ring groove body; turn over horizontal plane limit 1 in the groove inwall and be annular; the upper box cover 2 of a toroidal ring piece shape is equipped with in the groove top; the horizontal plane limit 1 of upper box cover 2 inner periphery limits and lower box body 8 joins; there is a space upper box cover inner periphery limit and lower box body 8 groove outer wall inboards; upper box cover 2 circumferential peripheries are drawn low pressure winding lead-out wire 3; and on the groove outer exterior wall; draw respectively and the corresponding lead-out wire 4 of low pressure winding lead-out wire the following peripheral; 6; upper box cover 2 lower casings 8 inside and outside walls all have insulating barrier; insulating sleeve sealing two ring groove shapes of protection box external application; iron core 7 is positioned at the protection box; low pressure winding lead-out wire 2 is connected with following cylinder manifold 15; last lead-out wire 4 joins with last cylinder manifold 16, and lead-out wire 6 is connected with support base plate 17 down, and sheath is around with high pressure winding 18.
The protection box is by lower box body 8; upper cartridge body 2; outter box 10 and outer lid 19 are formed; an annular insulation board 11 is equipped with in the lower box body top; the not outer lid 19 of shape of one circle is installed again on the plate; the inboard tight fit of insulation board 11 and outer lid 19 circumferential peripheries and lower box body 8 groove outer walls; drawing uniform post dish centre cap low pressure winding lead-out wire 21 on the outer lid circumferential periphery joins with middle cylinder manifold 20; outter box groove outer exterior wall is also drawn lead-out wire 4 and following lead-out wire 6; join with last cylinder manifold 16 and supporting bracket 17 respectively, the lead-out wire 3 and the following cylinder manifold 15 of drawing on the upper box cover 2 join.
Weld mutually with outer lid 19 on the horizontal plane limit of turning in the outter box 10 groove inboards.
Insulating sleeve is for to be combined relatively by two ring groove bodies.
Owing to take technique scheme, it is easy to make simple that the technology of the present invention is had, and processing parts is easy, guarantees product quality, the advantage of enhancing productivity, and this small product size is little simultaneously, and is in light weight, compact conformation, loss is little, and the life-span is long.
