Description
Technical field
The utility model is related to field transformer, more particularly to a kind of low voltage winding in transformers.
Background technology
Transformer is that a kind of voltage and current of grade is converted into another kind of same frequency etc. using electromagnetic induction principle
The voltage and current and the equipment of transmitting electric energy of level, the coil constitution equipment of transformer circuit part in itself, it with it is outside
Power network is directly connected to, and is most important part in transformer, therefore is referred to as " heart " of transformer.
Existing transformer coil has following defect：1. because circular configuration volume is bigger, spent copper material compares
Many, the space occupied is also big, and because coil is enclosed within core limb, the volume of coil is excessive also to cause core volume mistake
Greatly, cost and not readily transportable, installation be not only limit；2. the stay in air channel be all entrained in inside and outside two-layer coil it
Between, and stay is in strip, in order to ensure that the steadiness between inside and outside two-layer coil then has to strengthen between stay and coil
Contact surface, then must just increase the width of stay, this also just reduces the size in air channel indirectly, reduces radiating effect
(specifically such as：A kind of anti-breakdown transformer coil of CN205016352U), while can not be even between the air channel of stay both sides
Logical, this is also unfavorable for heat flow and radiating in coil.
The content of the invention
The purpose of this utility model is just to provide a kind of low voltage winding in transformers, repacks conventional circular coil into ellipse
Shape, reduces material usage amount, and will not also reduce the size in air channel while steadiness between coil is strengthened.
Technical problem of the present utility model is mainly addressed by following technical proposals：
A kind of low voltage winding in transformers, including outer layer low-voltage coil, internal layer low-voltage coil and by outer layer low-voltage coil with
The air channel constituted between internal layer low-voltage coil, the air channel sets respectively with the junction of outer layer low-voltage coil, internal layer low-voltage coil
There is air channel to insulate, it is axially arranged side by side in the air channel to have many bracing bars, and stay section is in I-shaped shape, correspondence in the stay
The end face of both sides is affixed with the insulation of corresponding air channel respectively, and stream of the section in equilateral triangle is also transversely provided with stay end face
Mutually be staggered setting in two end faces of groove, wherein stay between corresponding circulation groove.
Preferably, the stay is cut into by insulating board several paper slips simultaneously overlap bonding and form.
Preferably, the stay height is equal with coil height.
The beneficial effects of the utility model are：The utility model is improved to ellipse by by coil section, reduces
The cost and volume of coil, while namely reducing the cost and volume of iron core, reduce production, transport and the installation of product
Cost；Section is affixed in two end faces of the stay of I-shaped shape with the insulation of corresponding air channel, not only ensure that stay is exhausted with air channel
Contact area between edge is sufficiently large and inside and outside layer low-voltage coil between steadiness, while compared with conventional strip stay,
The air channel size of stay both sides is also increased, and circulation groove can then guide the circulation of gas between adjacent air channel, to accelerating coil
Radiating serve good effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of stay in the utility model.
In figure：1st, outer layer low-voltage coil, 2, internal layer low-voltage coil, 3, air channel, 4, air channel insulation, 5, stay, 6, circulation groove.
Specific embodiment
Below by embodiment, and with reference to accompanying drawing 1-2, the technical solution of the utility model is made more specifically
It is bright.
A kind of low voltage winding in transformers, including outer layer low-voltage coil 1, internal layer low-voltage coil 2 and by outer layer low-voltage coil
The air channel 3 constituted between 1 and internal layer low-voltage coil 2, the air channel 3 and outer layer low-voltage coil 1, the connection of internal layer low-voltage coil 2
Place is respectively equipped with air channel insulation 4, and axially arranged side by side in the air channel 3 to have many sections in I-shaped shape stay 5, stay 5 is external
Layer low-voltage coil 1 and internal layer low-voltage coil 2 play support firm effect, in the stay 5 end face of correspondence both sides respectively with it is right
The air channel insulation answered 4 is affixed, and circulation groove 6 of the section in equilateral triangle is also transversely provided with the end face of stay 5, wherein stay
Mutually be staggered setting in two end faces between corresponding circulation groove 6, and circulation groove 6 can guide the circulation of gas between adjacent air channel 3,
Radiating to accelerating coil serves good effect.
Several paper slips that the stay 5 is cut into by insulating board simultaneously overlap bonding and form, the height of the stay 5 and coil
It is highly equal.
The utility model is improved to ellipse by by coil section, reduces the cost and volume of coil, while
The cost and volume of iron core are exactly reduced, production, transport and the installation cost of product is reduced；Section is in the stay of I-shaped shape
5 two end faces are affixed with corresponding air channel insulation 4, not only ensure that the contact area between stay 5 and air channel insulation 4 is enough
Steadiness between big and inside and outside layer low-voltage coil, while compared with conventional strip stay, also increasing the both sides of stay 5
The size of air channel 3, and circulation groove 6 can then guide the circulation of gas between adjacent air channel 3, the radiating to accelerating coil is served actively
Effect.
One embodiment of the present utility model has been described in detail above, but the content is only of the present utility model
Preferred embodiment, it is impossible to be considered as limiting practical range of the present utility model.It is all to be made according to present utility model application scope
Impartial change with improve etc., all should still belong within patent covering scope of the present utility model.
