Abstract
The utility model discloses a kind of four-part form high-tension coil of 35kV grades of oil immersed type dihedral ring structure, including high-tension coil, the high-tension coil uses four cylindrical section formula structures, is made up of respectively high-tension coil I, high-tension coil II, high-tension coil III, high-tension coil IV.The utility model is simple in construction, with the low-voltage dual-voltage characteristic for the double transformer with split windings of oil immersed type, and improves the security and reliability and stability of its operation.
Description
Technical field
The utility model belongs to electrical equipment technical field, and in particular to the four of a kind of 35kV grades of oil immersed type dihedral ring structure
Segmentation high-tension coil.
Background technology
Traditional 35kV level transformer four-part forms high-voltage coil structure it is general 1 section of top, 2 with it is 3 intersegmental and 4 sections of tops are adopted
Positive square ring is used, this structure is feasible for the transformer of normal operating conditions；And 35kV grades of new energy oil immersed types become
Depressor, due to the inherent characteristic of harmonic content is high in its load and residing high thunderstorm takes place frequently environment, to high using this four-part form
In line ball circle 1 with it is 2 intersegmental and 3 totally unfavorable with 4 intersegmental dielectric strengths.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art that there is provided a kind of 35kV grades of oil immersed type dihedral ring knot
The four-part form high-tension coil of structure.
In order to reach above-mentioned purpose of design, the technical scheme that the utility model is used is：A kind of 35kV grades of oil immersed type is anti-
The four-part form high-tension coil of square ring structure, including high-tension coil, the high-tension coil use four cylindrical section formula structures, respectively by height
Line ball circle I, high-tension coil II, high-tension coil III, high-tension coil IV are constituted.
Upper and lower side is equal between upper and lower side and high-tension coil III, high-tension coil IV between the high-tension coil I, high-tension coil II
Provided with dihedral ring.
The high-tension coil is in coiling, and high-tension coil I and high-tension coil III intersect winding, high-tension coil II and height
Line ball circle IV intersects winding.
The high-tension coil average voltage is divided into four parts, per 1/4 that part is whole voltage.
The utility model beneficial effect：Between high-tension coil I, high-tension coil II with high-tension coil III, high-tension coil IV it
Between the dihedral ring placed can effectively suppress influence of the harmonic wave to transformer, increase section insulation intensity, improving transformer station high-voltage side bus can
By property, four sections of 35kV grades of oil-immersed transformer high-voltage coils can effectively reduce voltage between layers, reduce partial discharge quantity, improve anti-thunder
The ability of surge, improves the reliability of transformer station high-voltage side bus.The utility model is simple in construction, with for the double division changes of oil immersed type
The low-voltage dual-voltage characteristic of depressor, and improve the security and reliability and stability of its operation.

Figure；
Fig. 2 is traditional four-part form high-voltage coil structure schematic diagram.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.As shown in Figure 1-2：It is a kind of
The four-part form high-tension coil of 35kV grades of oil immersed type dihedral ring structures, including high-tension coil, the high-tension coil use four cylindrical sections
Formula structure, is made up of high-tension coil I 1, high-tension coil II 2, high-tension coil III 3, high-tension coil IV 4 respectively.
Between the high-tension coil I 1, high-tension coil II 2 between upper and lower side and high-tension coil III 3, high-tension coil IV 4 above and below
End is equipped with dihedral ring 5.
The high-tension coil is in coiling, and high-tension coil I 1 and high-tension coil III 3 intersect winding, high-tension coil II 2
Intersected winding with high-tension coil IV 4.
The high-tension coil average voltage is divided into four parts, per 1/4 that part is whole voltage.
When the utility model is used:By between high-tension coil I 1, high-tension coil II 2 with high-tension coil III 3, high-voltage line
Influence of the harmonic wave to transformer can effectively be suppressed by enclosing the dihedral ring 5 placed between IV 4, increase section insulation intensity, improve transformation
Device operational reliability, and the cylindrical section formula structure of high-tension coil four, four parts are equally divided into by high voltage, and every section is whole voltage
1/4, four cylindrical section formula structures can effectively reduce voltage between layers, reduce partial discharge quantity, improve the ability of lightning impulse resistant, improve
Transformer station high-voltage side bus reliability.
