Description
（One）Technical field
The utility model is related to a kind of transformer device structure, more particularly to a kind of single-phase voltage transformer body structure.
（Two）Background technology
At this stage, with the development of China's power system, 500kV transformer consumption rapid developments, and single transformer appearance
Amount is also increasing, considers in terms of manufacture, transport, installation dimension, investment and stand-by cost economy, needs three sometimes
Phase transformer is designed to the three-phase group transformer being made up of single-phase transformer, i.e., per a transformer is mutually designed to, is then becoming
Power station is combined by three single-phase transformers.
Currently, for single-phase transformer, single-phase three pillar type, single-phase four-column type and single-phase five limbs type core knot are typically designed as
Structure etc.；It is relatively conventional using single-phase three pillar type core construction for 500kV single-phase autotransformers；And according to user
To the requirement in terms of impedance voltage, conveyor width size, magnetic circuit, insulation and lead, need tap-changing windings design sometimes in list
On an other post in phase three pillar type core construction.According to transformer iron core structure design principle, single-phase three pillar type core construction
The cross-sectional area of other post is principal post cross-sectional area half or so, and the shape of the external construction line in its cross section is approximately oval；In mistake
The problem of going to bias toward consideration side post coil winding technological feasibility, is usually designed into circular configuration so that in this iron
Need by the heart to design a kind of auxiliary support apparatus in addition on post and become cylindrical structure, to ensure other post coil in its circumference side
There is the support of assured uniform upwards, to reach the requirement of transformer mechanical strength；But for this structure so that it is cased with coil
Iron core side pole centre-to-centre spacing less cover the big many of centre-to-centre spacing of post by coil sides, both sides magnetic circuit is extremely asymmetric, and transformer
Consumable quantity unshakable in one's determination is also big.It is therefore necessary to seek a kind of new design to solve this problem.
（Three）The content of the invention
There is provided a kind of structure is attractive in appearance, magnetic circuit tends to symmetrical, economy in order to make up the deficiencies in the prior art for the utility model
Type and practical single-phase voltage transformer body structure.
The utility model is achieved by the following technical solution：
A kind of single-phase voltage transformer body structure, including principal post unshakable in one's determination, it is unshakable in one's determination other that principal post both sides unshakable in one's determination are respectively arranged with left side
Post and right side iron core side pole, it is characterised in that：It is provided with arc, and right side iron core side pole and sets on the right side iron core side pole
It is equipped with the field winding and tap-changing windings of elliptic structure.
The utility model is based on the external construction wire shaped in post cross section by transformer core, by transformer excitation winding and tune
Press Winding Design into elliptic structure, add the support strength between field winding and tap-changing windings and iron core side pole, and lead to
The setting for crossing arc reduces the distance between post and principal post by the side, laughed at today transformer core silicon steel sheet, copper material,
The consumptions such as passage county, transformer oil, improve the symmetry of post magnetic circuit by transformer both sides.
More excellent technical scheme of the present utility model is：
The high oval winding former coiling of advanced technology, ovality is respectively adopted in the field winding and tap-changing windings, its
Holding strength between the iron core side pole of right side is significantly improved.
The utility model has that structure is attractive in appearance, magnetic circuit tends to be symmetrical, economy and it is practical the features such as, be primarily adapted for use in
500kV and the above carry the excitatory single-phase transformer of other post.
（Four）Brief description of the drawings
The utility model is further described below in conjunction with the accompanying drawings.
Fig. 1 is main structure diagram of the present utility model；
Fig. 2 is overlooking the structure diagram of the present utility model；
Fig. 3 is the main structure diagram of traditional single phase structure of transformer body；
Fig. 4 is the overlooking the structure diagram of traditional single phase structure of transformer body.
In figure, 1 principal post unshakable in one's determination, 2 left side iron core side poles, 3 right side iron core side poles, 4 arcs, 5 field windings, 6 pressure regulation around
Group, 7 auxiliary support apparatus, HWIt is high for window；MO1 is left side iron core side pole centre-to-centre spacing；MO2 be right side iron core side pole centre-to-centre spacing.
（Five）Embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.The embodiment includes principal post 1 unshakable in one's determination, the both sides of principal post 1 unshakable in one's determination
It is respectively arranged with left side iron core side pole 2 and right side iron core side pole 3, the right side iron core side pole 3 and is provided with arc 4, and it is right
The field winding 5 and tap-changing windings 6 of elliptic structure are provided with side iron core side pole 3.
For the symmetry saved manufacturing cost He promote the both sides magnetic circuit of principal post 1 unshakable in one's determination, based on iron core side pole cross section outside
The shape of construction line is connect, field winding 5 and tap-changing windings 6 are respectively designed to elliptic loop construction.
Single-phase voltage transformer body structure of the present invention, eliminates baroque auxiliary support apparatus on the iron core side pole 3 of right side
7, use instead with the high arc 4 of simple in construction, easily manufactured, intensity；So that between right side iron core side pole 3 and principal post 1 unshakable in one's determination
Centre-to-centre spacing reduce the most large stretch of wide distance of nearly 1/2 side post, while folder, fuel tank length, transformer oil consumption are also obtained
Different degrees of reduction.Magnetizing coil 5 and voltage regulation coil 6 reduce 25% or so with the average turn length of wire, reduce transformer
Copper material consumption；The high oval winding former coiling of advanced technology, ovality is respectively adopted in magnetizing coil 5 and voltage regulation coil 6, its
Holding strength between right side iron core side pole 3 is significantly improved, and the reliability of transformer station high-voltage side bus is obtained further
Improve.The utility model has that structure is attractive in appearance, magnetic circuit tend to symmetrically, economy and it is practical the features such as.
