Description

A kind of 110kV above three dimensional wound core transformer continuous winding
Technical field
The utility model relates to the technical field of power equipment, is specifically related to a kind of 110kV above three dimensional wound core transformer continuous winding.
Background technology
The high-tension coil of current 110kV above transformer generally adopts the structure of " inner shield continous way " or " being entangled with continous way ", and set up static board at end winding, still can normally work under ensureing the superpotential impact that coil causes in atmospheric over-voltage or operation.But inner shield continuous winding structure needs to insert shielding conductor at the turn-to-turn of active conductors, make the wire filling rate of whole coil reduce, and during coiling, shielding conductor, not with active conductors coiling, thus adds coiling operation, improves cost of manufacture.And distance between traditional " high-low " (or " high-in ") of being entangled with continuous winding structure is comparatively large, coil is compact not, and volume is larger.In addition, the static board of traditional 110kVA high-tension coil too increases the height of transformer, and the cost of transformer is also increased thereupon.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model be to provide a kind of compact conformation rationally, Short Circuit withstand and the strong continuous winding of overvoltage capabilities.
The utility model solves the technical scheme that its technical problem adopts:
A kind of 110kV above three dimensional wound core transformer continuous winding, described transformer comprises stereo-triangular wound core post,
Described stereo-triangular wound core post is wound with coil by vertical around mode,
Described coil comprises the paper web be socketed in outside stereo-triangular wound core post, and paper web is provided with stay, stay is wound with multiple line cake,
Described line cake comprises anti-section and wire that wire outside in moves into from the inner positive section outwards laid out, described anti-section and positive section are arranged alternately, and separate with the cushion block of insulation, adjacent anti-section and positive section interlink and form two segment unit, have at least in an anti-section or positive section and be provided with square ring in every two groups of two segment units.
As the further improvement of technique scheme, described anti-section and positive section are provided with and are entangled with line cake.
As the further improvement of technique scheme, between described paper web and stay, be provided with longitudinal oil duct.
As the further improvement of technique scheme, described cushion block is provided with horizontal oil duct.
As the further improvement of technique scheme, described end winding is provided with insulating end ring, ensures coil and external insulation.
The beneficial effects of the utility model are:
Continuous winding of the present utility model is mainly applicable to the high-tension coil of 110kV above transformer, adopting to stand directly is wound on stereo-triangular wound core post around mode, change the horizontal coiling of coil routine into longitudinal direction, make coil have more excellent operative weldability and coiling consolidation more, structure is compacter; Again owing to being provided with square ring in coil, ensure that the electrical strength of coil, improve coil filling rate and enhance the overall mechanical strength of coil.
In addition, in coil, be provided with longitudinal oil duct and horizontal oil duct, effectively improve the radiating effect of coil, reduce the working temperature of coil, extend its useful life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the coil of stereo-triangular wound core post and coiling;
Fig. 2 is continuous winding coiling expanded view of the present utility model.
Embodiment
With reference to Fig. 1, a kind of 110kV above three dimensional wound core transformer continuous winding that the utility model provides, comprise stereo-triangular wound core post 1 and coil 2, coil 2 adopts to stand and is wound on stereo-triangular wound core post 1 around mode, and coil 2 forms to being only a kind of wire continuous coiling topmost from bottom.
With reference to Fig. 2, coil 2 comprises the paper web 3 being arranged on innermost layer, paper web 3 is provided with stay 4, forms longitudinal oil duct between paper web 3 and stay 4.Stay 4 is wound with multiple line cake 5, line cake 5 comprises anti-section and wire that wire outside in moves into from the inner positive section outwards laid out, and anti-section and positive section are arranged alternately, and separate with the cushion block 10 of insulation, are provided with horizontal oil duct in cushion block 10.As shown in Figure 2, first anti-section 6 and the first positive section 7 interlink, first positive section 7 and the second anti-section 8 interlink, second anti-section 8 and the second positive section 9 interlink, repetition like this, interlinks adjacent anti-section and positive section, wherein, first anti-section 6 and the first positive section 7 form a two segment unit, and the second anti-section 8 and the second positive section 9 form a two segment unit.Between the positive section 9 of described first anti-section 6 to the second, at least one section is provided with square ring 11 and is provided with and be entangled with line cake 12.Online cake 5 arranges square ring 11, and what not only can effectively prevent between line cake 5 is creepage, can improve its Electric Field Distribution simultaneously; And be entangled with arranging of line segment 12 and can increase turn-to-turn capacitance, improve superpotential distribution, improve the anti-short circuit capability of coil 2.
