Abstract
The utility model provides a high-power high-frequency transformer. The transformer comprises an annular magnetic core made of ferrite; the surface of the magnetic core is coated with insulation resin; a primary coil adopts 6 mm<2> multi-strand enameled wire, a polyester film is arranged outside the wire, and 24 turns are coiled; a secondary coil adopts multiple 25 mm<2> multi-strand tinsel wires, a high-temperature yellow wax tube is arranged outside the wires, 2 turns are coiled, and the center of each wire is tapped. The high-power high-frequency transformer provided by the utility model has the beneficial effects that the physical loss of the transformer is small; when each circuit is in full load output, the temperature rising of the transformer is small, natural air cooling is realized, and the design of the cooling system is greatly simplified.
Description
Technical field
The utility model relates to a kind of transformer, especially relates to a kind of high-power high-frequency transformer.
Background technology
Domestic ultracrystallite material is subjected to the restriction of its production technology at present, crystallite band in process of production furnace temperature is difficult to evenly, the consistency of material has comparatively significantly difference, will bring harmful effect for the consistency of high power switching power supply inside multi-channel parallel structure like this.If adopt the ultracrystallite material price of international import very high again.Switching Power Supply has very strong nonstandard property in addition, and personalization is very strong, and product is difficult to the unified production of finalizing the design.Amorphous or the ultracrystallite magnetic core of the selection of material consistency shortcoming come the coiling high frequency transformer, the topological structure of transformer is restricted, be unfavorable for realizing on the one hand the diversity of product, the power of single transformer carrying is large on the other hand, the electric current that winding passes through is large, select wire diameter thick, increased the coiling difficulty of transformer.The factory that has produces family's employing copper pipe as the winding of secondary large electric current, and the technique of coiling copper pipe is more more complex than coiling copper cash, and copper pipe inside will lead to cooling circulating water, and this has increased again the design difficulty of cooling system.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, high-power high-frequency transformer that intensity is really up to the mark, safe and reliable.
The technical solution of the utility model is:
A kind of high-power high-frequency transformer comprises ferritic ring-shaped magnetic core, magnetic core surface spraying insulating resin, and primary coil adopts 6mm
2Multiply enamelled wire, line protect polyester film outward, coiling 24 circles, and secondary coil adopts many 25mm
2The multiply annealed copper strand wire protects the yellow cured pipe of high temperature outward, coiling 2 circles, centre cap.
By the transformer group that high-power high-frequency transformer forms, described transformer group comprises some transformers, and every transformer is around 24 circles, and the series connection of the primary coil of per two transformers becomes an elementary group, and a plurality of elementary groups are connected in parallel; Secondary coil coiling 2 circles, the twisted wire that secondary coil adopts passes from some transformer centers, and negative level copper bar arranges to realize centre cap as conversion terminal.
Advantage and the good effect that the utlity model has are:
Because adopt technique scheme, a plurality of transformers make up neatly, cross over the large gradient that realizes power, and different DC processes parameters output requirement.The general secondary current of the transformer of Switching Power Supply is larger, and the secondary winding transformer wire diameter is thicker, adopts a plurality of transformer connection in series-parallel, secondary be also can change flexibly output voltage according to customer requirement in the situation of a circle.The transformer active loss is little, and during fully loaded output, the transformer temperature rise is little on every road, has realized natural air cooledly, has greatly simplified the design of cooling system.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure:
1, magnetic core 2, primary coil 3, secondary coil
Embodiment
The utility model is described in further detail below in conjunction with the drawings and the specific embodiments.
As shown in Figure 1, the utility model comprises 10 transformers that are comprised of ferritic ring-shaped magnetic core 1, magnetic core 1 surface spraying insulating resin, and primary coil 2 adopts 6mm
2Multiply enamelled wire, line protect polyester film outward, and secondary coil 3 adopts 16 25mm
2The multiply annealed copper strand wire protects the yellow cured pipe of high temperature outward.Every transformer 2 is around 24 circles, and primary coil 2 series connection of per two transformers become an elementary group, and 5 elementary groups are connected in parallel; Secondary coil 3 coilings 2 circles, 8 twisted wires form a circle, and 16 twisted wires pass from 10 transformer centers, and negative level copper bar arranges to realize centre cap as conversion terminal.
In use, the transformer active loss is little, and during fully loaded output, the transformer temperature rise is little on every road, has realized natural air cooledly, has greatly simplified the design of cooling system.
Above execution mode has been described in detail the utility model, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
