Abstract
The invention discloses a transformer which can reduce volume and manufacturing cost, comprising an iron core. At least one winding is winded on the iron core, and each winding is formed by a single-layer but multi-circle coil. All windings form a multi-layer annular structure which takes the iron core as the center. Ventilation channels are respectively arranged between neighboring windings and also between the innermost winding and the iron core. And each winding is arranged into at least three sections, and each section is formed by at least two circles of coils, and a ventilation gap is arranged between sections. The invention is mainly applied to a power supply used for supplying power to a charging-discharging circuit of an accumulator.
Description
Technical field
The present invention relates to transformer.
Background technology
In the production technology of storage battery, need carry out alternately charging and discharge to storage battery, this process is called and changes into.At present, the power supply as the storage battery into charge and discharge circuit mainly is made of transformer and controllable silicon.Transformer plays the channeling of isolation, rectification, inversion as the main power component of power supply; The ratio that its cost accounts in whole power supply is quite big.Current transformer, its winding usually adopt traditional continuation mode coiling, adjacent coil together adjacent.In the course of the work, below winding, be provided with ventilation unit, it is carried out wind cooling temperature lowering.Generally, coil in the winding is high more from air inlet temperature rise far away more, coil in winding is wrapped in surperficial insulating barrier because of overheated burning out, just need add the thick line footpath, to reduce caloric value, like this, will cause the size of corresponding transformer framework and auxiliary member all to need to strengthen, thereby increased the volume of transformer, increased the manufacturing cost of transformer.
Summary of the invention
Technical problem to be solved by this invention is: a kind of transformer that reduces volume and reduce manufacturing cost is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: transformer, comprise: iron core, be wound with at least one winding on the iron core, each winding constitutes by the individual layer multiturn coil, and it is the multilayer circulus at center that all windings form with the iron core, between the adjacent winding, be provided with the ventilation air channel between the winding of innermost layer and the iron core, each winding is configured at least three sections again, and every section is made of two circle coils at least, is provided with ventilation voids between section and the section.
Be provided with ventilation gap between circle at least one section coil of each above-mentioned winding and the circle.
Above-mentioned transformer is provided with two windings, between the adjacent winding, be set together, form the ventilation air channel by equally distributed many support bars between innermost layer winding and the iron core.
The invention has the beneficial effects as follows: between innermost layer of the present invention winding and the iron core, be provided with the ventilation air channel between winding and the winding, and by with the coil grading in the winding, section with section between form ventilation voids, make that the heat radiation of winding is unobstructed; In addition, also can between circle in the multistage coil on the top of winding (away from air inlet) and circle, ventilation gap be set, make that the heat radiation of winding is more unobstructed, so just can reduce winding line footpath and with the size of corresponding transformer core of winding and auxiliary member, thereby can reduce the volume of transformer, reduce the cost of manufacture of transformer.

Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As Fig. 1, shown in Figure 2, transformer of the present invention, comprise: iron core 1, be wound with outer two windings 3 and 4 on the iron core 1, in, outer winding 3 and 4 constitutes by the individual layer multiturn coil, in, between the outer winding 3 and 4, be set together by equally distributed eight support bars 2 between interior winding 3 and the iron core 1, form ventilation air channel 9, in, outer winding 3 and 4 all is configured to first section coil 31, second section coil 32, the 3rd section coil 33 and 34 4 sections coils of the 4th section coil, these four sections coils are end to end successively, the free end of first section coil 31 and the 4th section coil 34 be respectively winding 3 on, following terminals 7 and 8, the structure of outer winding 4 is identical with the structure of interior winding 3, does not repeat them here; Every section coil is made of two circle coils at least, is provided with the ventilation voids 5 of about 20～30 mm wides between section and the section.In the present embodiment, in the 3rd section coil 33 on the top of transformer (away from air inlet),,, be provided with the ventilation gap 6 of about 2～3 mm wides between circle in this coil and the circle in order to increase its radiating effect because the turn ratio of coil is more.
The present invention is provided with ventilation air channel 9 between the winding 4 between interior winding 3 (innermost layer winding) and iron core 1 and outside interior winding 3 and 1, and pass through respectively with the coil grading in inside and outside winding 3 and 4, between section and section, ventilation voids 5 is set, makes that the heat radiation of inside and outside winding 3 and 4 is unobstructed; In addition, also can between circle in the coil on the top of inside and outside winding 3 and 4 (away from air inlet) and circle, ventilation gap 6 be set, make that the heat radiation of inside and outside winding 3 and 4 is more unobstructed, so just can reduce inside and outside winding 3 and 4 line footpath and with the size of inside and outside winding 3 and 4 corresponding transformer cores and auxiliary member, thereby can reduce the volume of transformer, reduce the cost of manufacture of transformer.
