Abstract
The utility model discloses a coil for a high-power transformer, which comprises an upper split coil and a lower split coil in parallel connection and adopting foil windings. The coil for the high-power transformer provided by the utility model has the advantages that the traditional high-power transformer is split into the upper part and the lower part, so that the requirement of a foil winding machine to the core shaft length can be satisfied, the coil suitable for the high-power transformer can be produced, and also, various shortcomings in winding the high-power transformer with wires can be overcome.
Description
Technical field
The utility model relates to a kind of transformer coil, particularly a kind of coil that is used for the bigger transformer of capacity.
Background technology
For jumbo transformer, its coil is adopted wire-wound usually at present, advantage is that the buying and the coiling of wire rod is convenient, but shortcoming is also quite obvious:
When (1) adopting wire-wound, coil processings that must replace, the just bigger loss of appearance easily when transposition is incomplete;
(2) the wound coil winding is lifted one's head and all is difficult to control in design with on the technology with the welding of copper bar outlet, is the key that influences the transformer quality;
(3) during the wire-wound low-voltage coil, the low pressure helical angle is big especially, and the short-circuit force that causes is big especially, and is also strict more to the fastening requirement of coil.
Part producer adopts paper tinsel formula winding to the high-power transformer coil, but because of there being following problems, also is difficult to operation:
(1) the foil winding equipment mandrel length of using at present mostly is two paper tinsel 1.4m greatly, and when manufacturing and designing the coil of larger capacity, its coil itself has surpassed mandrel length, can't use this equipment to finish;
(2) the low-voltage coil paper tinsel formula winding of larger capacity adopts two paper tinsel coilings usually, and welds with big copper bar or aluminium row, and the intensity that welding will reach and other requirement are difficult to guarantee, influence the crudy of coil;
(3) paper tinsel of larger capacity transformer is around material, do not have producer can satisfy dimensional requirement to foil.
The utility model content
The utility model purpose: at the problems referred to above, the purpose of this utility model provides a kind of coil that is applicable to high-power transformer.
Technical scheme: a kind of high-power transformer coil, comprise division upward coil and division lower coil, coil and described division lower coil are connected in parallel in the described division, and coil and described division lower coil are paper tinsel formula winding in the described division.
The wide size of paper tinsel of coil and described division lower coil equates in the described division, and with the impartial distribution of whole originally coil, the capacity of two division coils equates up and down.
Beneficial effect: compared with prior art, the utility model has the advantages that traditional high-power transformer coil is split into top and the bottom, to satisfy the requirement of foil winding equipment mandrel length, can produce the coil that adapts to high-power transformer, also avoid many shortcomings with wire rod coiling high-power transformer coil.
Description of drawings
Accompanying drawing is the structural representation of a kind of high-power transformer coil of the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
As shown in drawings, a kind of high-power transformer coil comprises division upward coil 1 and division lower coil 2, and coil 1 and described division lower coil 2 are connected in parallel in the described division, and coil 1 and described division lower coil 2 are paper tinsel formula winding in the described division.
The wide size of paper tinsel of coil 1 and described division lower coil 2 equates in the described division.
Claims (2)
1. high-power transformer coil, comprise division upward coil (1) and division lower coil (2), it is characterized in that: coil in the described division (1) and described division lower coil (2) are connected in parallel, and coil in the described division (1) and described division lower coil (2) are paper tinsel formula winding.
2. a kind of high-power transformer coil according to claim 1 is characterized in that: the wide size of paper tinsel of coil in the described division (1) and described division lower coil (2) equates.
