Description
Technical field
The utility model relates to transformer technology fields, and in particular to a kind of high-voltage coil structure of dry-type transformer.
Background technique
Existing tradition SCB class (epoxy pouring type) dry transformer high-tension coil is middle part voltage regulating, sectional circular cartridge type knot
Structure, loop construction are as shown in Figure 1.It has the following problems: 1, being according to the difference of the voltage of winding, if coil is divided into
Dry laminar segment unit, voltage is higher, and number of segment is more, and coiling is more complicated；2, cushioning layer insulation is wanted to guarantee before every layer of the number of turns
Its dielectric strength, every layer the number of turns are thicker more the layer insulation for adding pad；3, because being middle part voltage regulating, completing half is also needed line
Circle and mold u-turn are around remaining number of segment, complex procedures；4, it needs to be padded with insulating materials between the section of coil, after guaranteeing that coil stands up
It cannot be shifted between section, the dielectric strength that otherwise will cause between section not enough influences properties of product.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of high-voltage coil structure of dry-type transformer, make its around
Make simple, good insulating.
The utility model solve technical problem the technical solution adopted is that: a kind of high-voltage coil structure of dry-type transformer,
It is characterised in that it includes conducting wire and the iron core longitudinally extended along left and right, conducting wire winding in one direction on the iron core
At the line cake of multiple longitudinal gaps, each line cake is made of the multiturn of radial stacking；Outer circle one end of the line cake of left end is longitudinal
Outer circle one end of adjacent lines cake is extended to, interior circle one end of other each line cakes extends longitudinally to the outer circle one of right side adjacent lines cake
End；The line cake of left and right ends respectively draws a terminals outwardly；Epoxy resin is cast between each adjacent two line cake.
The loop construction of the utility model patent is not necessarily to be not necessarily to layer insulation, do not need more mold exchange side coil grading
To the disposably coiling of one high-tension coil of completion.

Specific embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing.In the utility model
Description in, it should be noted that term " center ", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outside"
The orientation or positional relationship of equal instructions is to be based on the orientation or positional relationship shown in the drawings, and being merely for convenience of description, this is practical new
Type and simplified description, rather than the device or element of indication or suggestion meaning must have a particular orientation, with specific orientation
Construction and operation, therefore should not be understood as limiting the present invention.In addition, term " first ", " second ", " third " are only used
In description purpose, it is not understood to indicate or imply and faces ground importance.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified
Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally
Connection；It can be mechanical connection, be also possible to be electrically connected；Can be directly connected, can also indirectly connected through an intermediary,
It can be the connection inside two elements.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
The concrete meaning of language in the present invention.
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Fig. 2, the high-voltage coil structure of the dry-type transformer of a preferred embodiment of the utility model comprising lead
Line and the iron core (not shown) longitudinally extended along left and right, conducting wire is on iron core in one direction around the line for being set as multiple longitudinal gaps
Cake, each line cake are made of the multiturn of radial stacking, are cast with epoxy resin between each adjacent two line cake.For example, First Line
The cake line cake of number (from left to right) is made of the 1st circle, the 2nd circle, the 3rd circle and the 4th circle this four circle.Second line cake is by the 5th~8
Circle is constituted, and third line cake is made of the 9th~12 circle.The rest may be inferred, and totally 12 line cakes form in the present embodiment, and each line cake is by four
Circle is constituted, in total 36 circle.Wherein, terminals A is drawn in interior circle one end of First Line cake, and interior circle one end of the tenth two wires cake, which is drawn, to be connect
Line end X.
Interior circle one end of second line cake extends to outer circle one end of third line cake, and interior circle one end of third line cake extends to
Outer circle one end of four line cakes.The rest may be inferred, and outer circle one end of the line cake of left end extends longitudinally to outer circle one end of adjacent lines cake,
Interior circle one end of other each line cakes extends longitudinally to outer circle one end of right side adjacent lines cake.
In the present embodiment, voltage difference only has 1 circle voltage between adjacent two circle of same line cake, between two neighboring line cake most
High voltage differential is 7 circle voltages, therefore wants much lower compared to existing sectional circular core structure.
It is and above-mentioned as shown in figure 3, the high-voltage coil structure of the dry-type transformer of another preferred embodiment of the utility model
Embodiment is slightly different, and First Line cake (a line cake of number from left to right) is made of the 1st~3 circle, and the second line cake is by the 4th
~6 circles are constituted, and third line cake is made of the 7th~9 circle.The rest may be inferred, totally 12 line cakes composition in the present embodiment, each line cake by
Three circles are constituted, in total 36 circle.Wherein voltage difference only has 1 circle voltage, two neighboring line cake between adjacent two circle of same line cake
Between ceiling voltage difference be 5 circle voltages.
Due to wanting much lower compared to existing sectional circular core structure, conducting wire itself insulation can satisfaction answer
And resistance to pressure request, therefore this loop construction is not necessarily to interlayer dielectic, more economically.Moreover, the coiling of this loop construction repeats
The coiling of each line cake need to only guarantee the insulating wrapping of cross-line between the number of turns and every cake, be not necessarily to halfway by coil and mold tune
Head improves coiling efficiency；Coil is all close-packed arrays in addition to cross-line position between every cake after complete stand up, will not be wired
The case where circle shifts, high reliablity；Under identical insulation conditions, distance be can be set smaller, more compact between line cake.
Above are merely preferred embodiments of the utility model, it is noted that those skilled in the art
For, without departing from the principle of this utility model, several improvements and modifications can also be made, these improvements and modifications
It should be regarded as the protection scope of the utility model.
The non-detailed portion of other in the utility model belongs to the prior art, therefore details are not described herein.
Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should
Understand: it is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of
Technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and this is practical new
The range of each embodiment technical solution of type.
