Abstract
The utility model discloses a kind of 110kV transformer insulation structure, including iron core (1), interior winding (3), high pressure winding (4) and the tap-changing windings (6) being successively set on from inside to outside in iron core (1) circumference, and it is arranged on the iron yoke (2) at iron core (1) two ends；Wherein, between interior winding (3) and (1) unshakable in one's determination, between high pressure winding (4) and interior winding (3) and between tap-changing windings (6) and high pressure winding (4), it is provided with insulating barrier.This utility model high pressure winding technique is simple, and upper end insulation declines, and barred window filling rate is high, and cost is less.Further, this utility model feature is that 110kV high pressure winding uses continuous structure, and cancels end static board, and interior winding insulation is strengthened.
Description
Technical field:
This utility model relates to a kind of 110kV transformer insulation structure, it is adaptable to the 110kV transformation of double winding or Multiple coil
Device.
Background technology:
At present, the transformator of 110kV electric pressure, due to surge voltage safety requirements, the high pressure winding generally company of being entangled with
Continuous or inner screen continuous structure, and upper end placement static board.
This kind of structure transformer high pressure winding technique is complicated, and manufacturing cost is higher；Static board is arranged at winding top, and upper end is exhausted
Edge distance is big, relatively costly.
Utility model content:
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, it is provided that a kind of 110kV is transformer insulated
Structure, is characterized in that 110kV winding uses continuous structure, and coiling is simple；Cancelling end static board, upper end insulation distance drops
Low.
For reaching above-mentioned purpose, this utility model adopts the following technical scheme that and realizes:
A kind of 110kV transformer insulation structure, including iron core, be successively set on from inside to outside in circumference unshakable in one's determination interior around
Group, high pressure winding and tap-changing windings, and it is arranged on the iron yoke at two ends unshakable in one's determination；Wherein, between interior winding and iron core, high pressure winding
And it is provided with insulating barrier between interior winding and between tap-changing windings and high pressure winding.
This utility model is further improved by, and high pressure winding uses the high pressure winding of continuous way.
This utility model is further improved by, and the outside of interior winding is provided with soft corner-ring.
This utility model is further improved by, and is provided with soft corner-ring inside and outside the upper and lower end parts of high pressure winding.
This utility model is further improved by, insulating barrier, high pressure winding and the interior winding between interior winding and iron core
Between insulating barrier and tap-changing windings and high pressure winding between insulating barrier all use special insulation cardboard to make.
Relative to prior art, this utility model has a following beneficial effect:
This utility model high pressure winding continuous structure, coiling is simple, effectively reduces cost of labor.
Further, this utility model feature is and cancels 110kV winding overhang static board, and upper end insulation declines, ferrum
Window filling rate is high, and materials consumption rate is decreased obviously, and cost is less；The most inside and outside winding overhang insulating strength, it is ensured that electrically pacify
Entirely.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model:
In figure: 1 is unshakable in one's determination, and 2 is iron yoke, and 3 is interior winding, and 4 is high pressure winding, and 5 is soft corner-ring, and 6 is tap-changing windings.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As it is shown in figure 1, this utility model one 110kV transformer insulation structure, including the high pressure winding 4 of continuous way, absolutely
Interior winding 3, tap-changing windings 6, unshakable in one's determination 1 and the iron yoke 2 that edge is strengthened.
Concrete structure of the present utility model is, from unshakable in one's determination 1 be followed successively by from inside to outside interior winding 3, high pressure winding 4, pressure regulation around
Group 6；Increasing soft corner-ring 5 reinforced insulation outside interior winding 3, high pressure winding 4 is to have inside and outside continuous structure, and upper and lower end parts
Soft corner-ring 5 reinforced insulation.Additionally, between interior winding 3 and unshakable in one's determination 1, between high pressure winding 4 and interior winding 3 and tap-changing windings 6 with
It is provided with insulating barrier between high pressure winding 4, and insulating barrier uses special insulation cardboard to make.
It is to illustrate this utility model described in above-described embodiment, though literary composition is illustrated by specific term,
But the protection domain that can not limit this patent with this, the personage being familiar with this technical field can understand spirit and the principle of this patent
Afterwards it is changed or revise and reach equivalence purpose, and this equivalence change and amendment, all should be covered by right
In defined category.
