Abstract

The utility model relates to a layer-rising structure of twin U-shaped coils, and belongs to the technical field of transformers. The technical scheme includes that the layer-rising structure comprises an upper inner coil (1), a lower inner coil (4), an upper outer coil (6), a lower outer coil (7) and an end coil (2), the upper inner coil and the lower inner coil share the same coil direction to the right, while the upper outer coil and the lower outer coil share the same coil direction to the left, and the end coil is arranged between the upper inner coil and the upper outer coil and the lower inner coil and the lower outer coil. The same direction of the coils in the layering structure can guarantee distance between coils on rising layers between the upper coils and the lower coils. A slope of a conducting line can be guaranteed by leveling up an inclined portion of the end coil through a bearer, angle rings are buckled outside the coils of the rising layers to increase safety margin between the upper coils and the lower coils, further increase the safety margin in the middle of a high-tension coil, and operation safety is guaranteed.

Description

The dual U-shaped coil rise layer structure
Technical field
What the utility model related to a kind of dual U-shaped coil rises layer structure, belongs to the transformer technology field.
Background technology
At present, in traditional axial split transformer, two low-voltage coils are axial arranged, lift one's head and drawn by the internal coil diameter side in the middle part.Outlet difficult treatment on the one hand, technique is dispersed large, the reliability of the middle part outlet of the low-voltage coil of axial split is under suspicion, capacity along with the axial split transformer constantly increases on the other hand, the low-voltage coil electric current constantly increases, the middle part outlet takes up room very large, and the transformer cost rolls up, and its economy also is under suspicion.In the axial split transformer, two axial arranged coils all are designed to the double-layer spiral formula, and namely dual U-shaped, connect by the liter layer between dual U-shaped ectonexine wire, and the processing that the liter layer is located directly affects economy and the reliability of product.
The utility model content
What the utility model purpose was to provide a kind of dual U-shaped coil rises layer structure, it is the U-shaped that in the axial split transformer, two axial arranged coils all are designed to the double-layer spiral formula, winding protruding head is all in the end, connect by rising layer in the middle part of coil between inside and outside layer conductor, handle well and rise layer connection, improve economy, the reliability of product, solve the problems referred to above that background technology exists.
The technical solution of the utility model is: a kind of dual U-shaped coil rise layer structure, comprise top inner coil, bottom inner coil, upper outer layer coil, bottom outer coil and end circle, top inner coil and bottom inner coil be around to identical, for the right side around to; Upper outer layer coil and bottom outer coil be around to identical, for a left side around to; Top inner coil and upper outer layer coil, and place the end circle between bottom inner coil and bottom outer coil.
Inclination place of end circle arranges cushion block and levels up, and square ring is buckled in the line cake outside, end circle place.
The beneficial effects of the utility model: two coils are double-layer spiral formula U-shaped structure, two coils are arranged up and down, top inner coil and bottom inner coil are around to identical, upper outer layer coil and bottom outer coil are around to identical, can guarantee that lower coil rises layer and locates distance between the line cake, inclination place of end circle is leveled up with cushion block and can be guaranteed the wire slope, square ring namely can increase margin of safety between upper and lower coil outside being buckled in and rising the layer line cake, can increase again the margin of safety to the high-tension coil middle part, guarantee security of operation.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram;
In figure: top inner coil 1, end circle 2, bottom inner coil 4, square ring 5, upper outer layer coil 6, bottom outer coil 7.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is described further.
A kind of dual U-shaped coil rise layer structure, comprise top inner coil 1, bottom inner coil 4, upper outer layer coil 6, bottom outer coil 7 and end circle 2, top inner coil and bottom inner coil be around to identical, for the right side around to; Upper outer layer coil and bottom outer coil be around to identical, for a left side around to; Top inner coil and upper outer layer coil, and place the end circle between bottom inner coil and bottom outer coil.Inclination place of end circle arranges cushion block and levels up, and square ring 5 is buckled in the line cake outside, end circle place.

Claims (2)

1. a dual U-shaped coil rises layer structure, it is characterized in that: comprise top inner coil (1), bottom inner coil (4), upper outer layer coil (6), bottom outer coil (7) and end circle (2), top inner coil and bottom inner coil be around to identical, for the right side around to; Upper outer layer coil and bottom outer coil be around to identical, for a left side around to; Top inner coil and upper outer layer coil, and place the end circle between bottom inner coil and bottom outer coil.
Dual U-shaped coil according to claim 1 rise layer structure, it is characterized in that: inclination place of end circle arranges cushion block and levels up, square ring (5) is buckled in the line cake outside, end circle place.
