Abstract
The utility model proposes the high-tension coil of a kind of two sections continuous cake formula structures, high-tension coil uses continuous cake formula structure, winding wire integrally divides two sections, the intersegmental certain intersegmental distance of design, each circle wire is along coil width to arrangement, naked layer, the cake of coil first paragraph first and the back-roll of the cake of second segment first（Anti- cake）, other cakes just around（Positive cake）, circumferentially divide 8 imaginary stay positions from coil panel center, this is also 8 bit positions of wire, forms a fixed gap between each line cake at wire transposition, penetrates into form passage for resin.Resin penetration under vacuum conditions has prevented the presence of air gap, cavity than more uniform, thorough, between conductor, and the high-tension coil after being heating and curing high-volume, turns into a rigid body without part.
Description
Technical field
The utility model belongs to the technical field of power equipment, and in particular to the resin of a kind of two sections continuous cake formula structures
Casting dry type transformer high-tension coil.
Background technology
It is well known that typically use four-part form laminar for 10kV grade resins cast dry-type distribution transformer high-tension coil
Structure, arrange per section lead, separated between adjacent wire layers with insulating paper in layer vertically, wire is intersegmental have it is certain intersegmental
Away from coil both ends stay the end of certain distance to insulate, and the coil that coiling is completed is placed on die cavity and carries out resin-cast, is then heating and curing
Into steel body.
The coil of this structure, interlayer, turn-to-turn coiling are close, and easily causing resin during vacuum pouring can not impregnate completely,
Small air gap, cavity are left between conductor and conductor, conductor and insulation, causes coil partial discharge quantity big after solidification, is influenceed
Transformer use reliability and service life, loss is brought to electric unit.
Utility model content
The purpose of this utility model is to provide a kind of new structure, for the high-voltage line of resin filled type dry-type transformer
Vacuum pouring, curing characteristics are enclosed, improves its operational reliability and service life.
In order to solve the above technical problems, the technical solution adopted in the utility model is：High-tension coil uses continuous cake formula knot
Structure, winding wire integrally divide two sections, and the intersegmental certain intersegmental distance of design, each circle wire is along coil width to arrangement, without absolutely
Edge layer, the cake of coil first paragraph first and the back-roll of the cake of second segment first（Anti- cake）, other cakes just around（Positive cake）, from coil panel
The heart, which rises, circumferentially divides 8 imaginary stay positions, and this is also 8 bit positions of wire, is formed between each line cake at wire transposition
One fixed gap, penetrate into form passage for resin.
The further winding wire is high electric strength insulation flat conductor.
Using the beneficial effect of above-mentioned technical proposal：Resin penetration under vacuum state is shut out between conductor than more uniform, thorough
The presence of air gap, cavity absolutely, high-tension coil after being heating and curing without it is local high-volume, turn into a rigid body.The program has notable
Practicality, it is easy to be acceptable to the market popularization.

Embodiment
The high-tension coil of four sections of layered structures belongs to prior art, and it includes the high voltage layer type provided with multiple winding protruding heads and led
Line, and the coil-end insulating barrier at laminar wire both ends, the insulating barrier are divided into external insulation and interior insulation, and high-tension coil is divided into I-
IV section, wire hierarchal arrangement vertically places layer insulation between adjacent two layers, it is adjacent it is intersegmental there is certain distance to make intersegmental distance,
Coil both ends preset space makees end insulation, and resin vacuum cast, be heating and curing shaping.
Referring to shown in Fig. 1-5, the utility model proposes the high-tension coil of a kind of two sections continuous cake formula structures, including provided with
The high wafering type wire of multiple winding protruding heads and the coil-end insulation at both ends, the insulation are divided into coil external insulation 8 and coil
Insulate 7, in addition to the first cake of coil first paragraph 1, cake between distance 2, the second cake of coil 3, the first cake of coil first paragraph transposition 4 and
The other cake transpositions 5 of coil, the coil are divided to upper and lower two sections, and wire is along coil width to being arranged in continous way pie, its coil
The first cake of first paragraph 1, the first cake of coil second segment 6 are anti-cake, and other cakes are positive cake, and without layer insulation, using face plate center as
Starting point, circumferentially respectively 8 positions, are the bit positions preset clearance between cake per cake wire transposition position, and coil upper and lower ends are pre-
The intersegmental distance 9 of electric insulation is left, winding wire described further is high electric strength insulation flat conductor, and high-tension coil uses ring
Oxygen tree fat disposal vacuum is poured into a mould, and be heating and curing shaping.
The technical solution of the utility model is not restricted in the range of embodiment described in the utility model, and this practicality is new
The technology contents of the not detailed description of type are known technology.
