Abstract
The invention discloses a winding for a transformer. The winding comprises an iron core, a high-intensity insulation cylinder, a low voltage winding and a high voltage winding; the winding for the transformer is characterized in that: inner axial support strips which are arranged along the circumference of the high-intensity insulation cylinder in an equant way are arranged outside the high-intensity insulation cylinder; the low voltage winding is wound on the inner axial supporting strips; an inner lock support strip, and outer axial support strips which are arranged along the circumference of the low voltage winding in an equant way are arranged outside the low voltage winding sequentially; the high voltage winding is wound on the outer axial supporting strips; and an outer lock support strip is arranged outside the high voltage winding. The winding for the transformer is high in mechanical intensity, and short circuit resistance capacity, and low in the temperature rising of the maximum point and has long service life.
Description
Technical field
The present invention relates to power equipment and make the field, it is high particularly to relate to a kind of mechanical strength and anti-short circuit capability, the Transformer Winding of long service life.
Background technology
Development and lifting along with transformer technology; Various big capacity high voltage transformers are designed and develop; And each item technical parameter of transformer also constantly increases; This type of novel transformer requires increasingly high to each side such as the temperature rise of winding, Short Circuit withstands, therefore need a kind of novel transformer winding structure to satisfy its needs.
The high and low pressure winding of traditional Transformer Winding is enclosed within each winding on the iron core and shaping compresses and processes through independent the making more in order successively; Can leave the gap unavoidably between its each winding, this structure can be brought following deficiency: the one, because of the size that increases winding has increased the cost of transformer, the 2nd, because of each winding suit not compact; Concentricity is poor; The width of cloth causes its mechanical Strength for Winding and anti-short circuit capability not high to discontinuity, and the 3rd, each winding can not get protection when assembling; Grazing mutually easily each other causes the winding surface insulation layer to damage.In addition; Traditional Transformer Winding also has through the structure of stay and cushion block structure oil duct is set; To solve the problem of temperature rise of winding, be axial single oil duct design mostly, effect is limited; And stay the also not clear and definite reasonably standard in position specifically is set, also cause the winding width of cloth to problems such as discontinuity, stay displacements easily.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes prior art, provides a kind of mechanical strength and anti-short circuit capability high, and the temperature rise of winding peak is low, the Transformer Winding of long service life.
For solving the problems of the technologies described above; The present invention provides a kind of Transformer Winding; Comprise iron core, high strength insulating cylinder, low pressure winding and high pressure winding; It is characterized in that: the said high strength insulating cylinder outside is provided with the interior axial stay that is provided with along branches such as high strength insulating cylinder circumference, and said low pressure winding technique is said in axially on the stay, and the said low pressure winding outside is provided with the internal lock stay and successively along the outer axial stay of branches such as low pressure winding circumference setting; On the axial outside stay of said high pressure winding technique, the said high pressure winding outside is provided with the external lock stay.Said interior axially stay is with axially stay is respectively along branch settings such as high strength insulating cylinder and low pressure winding circumference outward, and rationally distributed, the width of cloth is to stressed even; Stability Analysis of Structures, concentricity is high, and internal lock stay and external lock stay play further fastening effect; Improve mechanical strength and anti-short circuit capability; And cooperates with interior axial stay and outer axially stay and to form axial oil duct and the width of cloth to oil duct, thereby reduction winding temperature rise at the hottest point increases the service life.
Aforesaid Transformer Winding is characterized in that: said low pressure winding is a sped structure, and said high pressure winding conducting wire is an oxygen-free cupreous, and said interior axially stay, outer axially stay, internal lock stay and external lock stay are preparatory closeization chamfering stay.
The beneficial effect that the present invention reached:
Mechanical strength and anti-short circuit capability are high, and the temperature rise of winding peak is low, long service life.
Description of drawings
Fig. 1 is a cross-sectional structure sketch map of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described.
As shown in Figure 1; High strength insulating cylinder 1 outside is provided with the interior axial stay 2 that is provided with along branches such as insulating cylinder circumference; Spiral low pressure winding 4 is wound on the said interior axially stay 2; The outer axial stay 3 that said low pressure winding 4 outsides are provided with internal lock stay 6 successively and are provided with along branches such as low pressure winding circumference is wound on the outer axially stay 3 by the high pressure winding 5 of oxygen-free cupreous coiling, and said high pressure winding 5 outsides are provided with external lock stay 7.
In addition; All stays are all through preparatory closeization, chamfered; The equal dipping lacquer cured of winding coil; Adopt during design of Windings that low electricity is close, oil duct, the width of cloth to improve winding mechanical strength and anti-short circuit capability, satisfy the requirement of the high in short-term overload of electric power system to transformer to the design of fastening " 0 " nargin between amplifying sections.The coil axial pressing force is controlled in strict accordance with technological requirement, makes each coil compress its electromagnetic center height of back on same horizontal line, and corresponding line cake is strict with ampere-turn equilibrium requirement control, and its axial force and the stress of conductor are minimum when guaranteeing transformer short-circuit.This structure forms axial oil duct and the width of cloth to oil duct in Transformer Winding, reduced the temperature rise of winding peak, has prolonged useful life.
Mechanical strength of the present invention and anti-short circuit capability are high, and the temperature rise of winding peak is low, long service life.
Above embodiment limits the present invention never in any form, and every other improvement and application that above embodiment is made with the equivalent transformation mode all belongs to protection scope of the present invention.
