Abstract
The utility model discloses a kind of four sections of 35kV grades of oil-immersed transformer high-voltage coils, 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 a kind of four sections of 35kV grades of oil-filled transformer high pressures
Coil.
Background technology
Common oil immersion-type distribution transformer high-voltage coil structure is usually a cylindrical section formula, and this structure is for 10kV grades
For transformer, because its voltage is relatively low, voltage between layers is not comparatively also high, and what does not result in transformer in operation
Harm；For 35kV grades of transformers, because its rated voltage is higher, voltage between layers is also higher, in the presence of high field intensity, high
Partial discharge quantity is larger in line ball circle, and the ability of lightning impulse resistant is weak.35kV grades of new energy oil-filled transformers are residing for it
The particular surroundings that takes place frequently of high thunderstorm, to totally unfavorable using the high-tension coil of this one-part form cylinder mode.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and there is provided a kind of four sections of 35kV grades of oil immersed type transformations
Device high-tension coil.
In order to reach above-mentioned purpose of design, the technical scheme that the utility model is used is：A kind of four sections of 35kV grades of oil immersions
Formula transformer high-voltage coil, including high-tension coil, the high-tension coil use four cylindrical section formula structures, respectively by high-tension coil I,
High-tension coil II, high-tension coil III, high-tension coil IV are constituted.
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：Four sections of 35kV grades of oil-immersed transformer high-voltage coils can effectively reduce voltage between layers,
Reduce partial discharge quantity, improve the ability of lightning impulse resistant, improve the reliability of transformer station high-voltage side bus.The letter of the utility model structure
It is single, with the low-voltage dual-voltage characteristic for the double transformer with split windings of oil immersed type, and improve the security of its operation and reliable and stable
Property.
Brief description of the drawings
Fig. 1 is four sections of 35kV grades of oil-immersed transformer high-voltage coils structural representations of the utility model；
Fig. 2 is the high-voltage line structural representation of existing cylinder mode.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.As shown in Figure 1-2：One kind four
35kV grades of oil-immersed transformer high-voltage coils of section, including high-tension coil, the high-tension coil use four cylindrical section formula structures, respectively
It is made up of high-tension coil I 1, high-tension coil II 2, high-tension coil III 3, high-tension coil IV 4.
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 the cylindrical section formula structure of high-tension coil four, high voltage is equally divided into four parts,
Every section is the 1/4 of whole voltage, and four cylindrical section formula structures can effectively reduce voltage between layers, reduce partial discharge quantity, improve anti-thunder
The ability of surge, improves transformer station high-voltage side bus reliability.
