Abstract
The invention relates to a wound transformer comprising a core and coils wound on the core. The coils include a primary coil and a secondary coil. Each coil in a spiral shape having an inner wall and an outer wall is formed by winding a rectangular-sectioned flat conductor around an axis to form a hollow. The wound transformer has the advantages that winding tightness of the coils is increased, flux leakage of the transformer is reduced, and voltage is stabilized; in addition, radial mechanical strength of the coils is enhanced, overload capacity of the transformer is improved, and the service life of the transformer is prolonged.
Description
Technical field
The present invention relates to a kind of transformer, relate to particularly a kind of coiling transformer.
Background technology
Transformer is to utilize the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core, mainly contains the functions such as voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing.Transformer coil commonly used is formed by the plain conductor coiling of circular cross-section, although the wire coiling of circular cross-section is convenient, fast, efficiency is high, yet the coil gap is larger, causes the leakage field phenomenon more serious.
Granted publication number discloses a kind of coil for the Chinese invention patent of CN102044330B, one side of the winding of the winding of the coiling end side of the winding consisted of many wires and coiling top side reels towards outer circumferential side from inner circumferential side, and the opposing party draws from inner circumferential side towards outer circumferential side, described many wires longitudinally stacked state are reeled together, at the cross section of the winding of the winding of described coiling end side and described coiling top side, make these many wires overlapping and intersect along the state of laterally setting level.Such coil can reduce the height of cross section significantly, form the height identical with other zones, yet the transformer leakage field phenomenon of utilizing this coil to make is serious.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art a kind of coiling transformer of effective minimizing leakage field.
For achieving the above object, the technical solution adopted in the present invention is: a kind of coiling transformer, comprise iron core, the coil of winding on described iron core, described coil comprises primary coil and secondary coil, the flat conductor that described coil is rectangle by cross section turns to hollow and has a helical form of inner and outer wall around an axis, the outer peripheral face of described flat conductor is comprised of two relative broadside side narrow flank side surface relative with two, wherein an adjacent described broadside side and a described narrow flank side surface has a common long side, in the broadside side, another side adjacent with described long side is its wide side, in described narrow flank side surface, another side adjacent with described long side is its narrow side, the length of described wide side is greater than the length of described narrow side, it is characterized in that: described narrow flank side surface forms the inner and outer wall of described spiral helicine coil, described broadside side is vertical with the axis of described spiral helicine coil.
Optimally, described iron core is " day " font, comprises the center pillar that parallels setting, two side columns, and described coil winding is on described center pillar and side column.
Further, rounded, the ellipse or square of described coil section.
Further, described coil is for being greater than 2 circles.
Because technique scheme is used, the present invention compared with prior art has following advantages: coiling transformer of the present invention, because adopting the flat metal wire, coil turns to the helical form with inner and outer wall, and the narrow flank side surface of flat metal wire forms the inner and outer wall of spiral helicine coil, the broadside side is vertical with the axis of coil, can improve the tightness degree of coil winding on the one hand, reduce the leakage field of transformer, burning voltage; Improve on the other hand the radial mechanical strength of coil, improved the overload capacity of transformer, extended the useful life of transformer.
The accompanying drawing explanation
Accompanying drawing 1 is coiling transformer front view of the present invention;
Accompanying drawing 2 is coiling transformer left view of the present invention;
Wherein: 1, iron core; 11, side column; 12, center pillar; 2, coil; 21, broadside side; 22, narrow flank side surface.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiment of the invention is elaborated.
Coiling transformer as shown in Figure 1-2, mainly comprise iron core 1 and be set around the coil 2 on iron core 1.Wherein, coil 2 comprises primary coil and secondary coil, and has the inner and outer wall be parallel to each other, and by flat conductor, around an axis, turns to the cored screw shape.The cross section of flat conductor is rectangle, its outer peripheral face is connected around forming in twos by four sides, wherein two relative sides are broadside side 1, two other is narrow flank side surface 2, broadside side 1 is the rectangle surrounded by wide side a and long side c, narrow flank side surface 2 is the rectangles that surrounded by narrow side b and long side c, broadside side 1 and narrow flank side surface 2 have common long side c, and the length of wide side a is greater than the length of narrow side b, narrow flank side surface 2 forms the inner and outer wall of spiral coil, and broadside side 1 is vertical with the axis of spiral coil.Because the length of wide side a is greater than the length of narrow side b, increased the radial mechanical strength of coil, improved the overload capacity of transformer, extended the useful life of transformer; And the every turn-to-turn arrangement of coil closely, reduces the leakage field of transformer, burning voltage.
In the present embodiment, iron core 1 is " day " font, comprises the center pillar 12 that parallels setting, two side columns 11; Coil 2 is set around on side column 11, center pillar 12.In use, can be according to the difformity of iron core, the difform coil of coiling.Hollow circle body 3 cross sections are rounded, on center pillar 12 and side column 11 that to be set around cross section be rectangle.In addition, because the one turn voltage of different coils is the same, coil can be arranged to the purpose that the different numbers of turn reaches regulation voltage, be widely used in the fields such as transformer, in the present embodiment, the hollow circle body number of turn is optimized for and is greater than 2 circles.
Above-described embodiment is only explanation technical conceive of the present invention and characteristics, and its purpose is to allow the person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
