Abstract
The utility model discloses a three-winding coil structure of a non-encapsulated dry type transformer, which comprises a first low-voltage coil, a second low-voltage coil and a high-voltage coil. The high-voltage coil is positioned at the outer side of the two low-voltage coils; the first low-voltage coil is formed by connecting two parts; the second low-voltage coil is positioned between the two parts of the first low-voltage coil; the two parts of the first low-voltage coil have the same number of turns. Compared with the prior art, the three-winding coil structure of the non-encapsulated dry type transformer of the utility model has the advantage of having balanced output voltage.
Description
Technical field
The utility model belongs to the transformer accessory technical field, particularly a kind of no-encapsulated-winding dry-type transformer three winding coil structures that are applicable to.
Background technology
The existing non-loop construction of sealing three winding dry-type transformers is independent in order from inside to outside the arrangement: first low-voltage coil is in the inboard, and second low-voltage coil is in the centre, and high-tension coil is in outermost.They fix respectively by upper clamping piece and insulator in outlet, thereby realize the effect that two or more voltages are exported simultaneously, first low-voltage coil is to the impedance voltage U13 of high-tension coil, and second low-voltage coil is bigger to the difference between the impedance voltage U23 of high-tension coil, thereby cause that two kinds of voltage outputs are uneven, do not match with corresponding apparatus voltage.
Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, and provides a kind of three windings to export the winding coil structure that two or more impedance voltages equate.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: comprise first low-voltage coil, second low-voltage coil and high-tension coil, described high-tension coil is positioned at the outside of two low-voltage coils, described first low-voltage coil is connected to form by two parts, and described second low-voltage coil is positioned in the middle of first low-voltage coil two parts.
The two-part equal turn numbers of described first low-voltage coil.
Compared with prior art, the utility model is with the first low-voltage coil separated into two parts, and second low-voltage coil is wrapped between first low-voltage coil two parts, two parts with first coil link together then, twine high-tension coil at last, the cross structure of this second low-voltage coil and first low-voltage coil has been guaranteed the equality of two or more impedance voltage values of three winding coils, thereby has guaranteed the equivalence of output voltage.
Description of drawings
Fig. 1 is a coiling schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated, as shown in Figure 1, the part (1a) of coiling first low-voltage coil 1 at first places the inboard around half number of turn of first low-voltage coil (1); And then place second low-voltage coil (2); And then,, with two parts (1a) with (1b) by wire bonds, place high-tension coil (3) at last then around second half number of turn of first low-voltage coil (1) around another part (1b) of coiling first low-voltage coil (1).After finishing, fix the outlet terminal of these three coils by insulator and folder.
Claims (2)
1, a kind of no-encapsulated-winding dry-type transformer three winding coil structures, comprise first low-voltage coil (1), second low-voltage coil (2) and high-tension coil (3), described high-tension coil (3) is positioned at the outside of two low-voltage coils, it is characterized in that described first low-voltage coil (1) by (1a) and (1b) two parts connect to form, described second low-voltage coil (2) is positioned at first low-voltage coil (1) two parts (1a) and centre (1b).
