Abstract
The present invention relates to a kind of New-type transformer low tension coil structure, including coil layer, inner bracing strip, outer stay, parallel conducting wires;The coil layer includes inner bracing strip and outer stay, and the coil layer is made of the copper foil of alternate combinations and layer insulation, and parallel conducting wire is placed in coil layer, and with width to 2, axial 2 conductor in parallel, 4 cakes are a unit.It solves the problems, such as that the line gauge width of single spiral coil chooses excessive caused temperature rise of hot spot and the line gauge width of double-spiral coil chooses too small caused axial bending resistance deficiency problem, while improving product reliability, also improves the economy of product.
Description
Technical field
The invention patent relates to a kind of New-type transformer low tension coil structures.
Background technology
In the power system, we complete biography of the electric energy between power plant to user using various types of transformers
It is defeated.With the rapid development of power equipment, electric power proportion in the Working Life of socio-economic development and people is also more next
It is bigger.With the increase of power demand, the capacity of transformer also the more does the more big therewith.With people's household electricity proportion
Increase, the load fluctuation of transformer is also increasing;With greatly developing for all kinds of power generating equipments, the capacity of step-up transformer
It is more and more extensive.For large capacity step-up transformer, low-voltage coil the number of turns is few, electric current is big, selects loop construction pattern difficult.Through
It is very little often to there is single-screw coil cake number, causes line gauge width larger, eddy-current loss is very big caused by end cross leakage field, both
Increasing the loss of product also causes end temperature rise of hot spot excessively high;The coil cake number of double helix is excessive, causes line gauge width too small,
Both caused line cake axial direction bending strength insufficient, the increase of oil duct quantity, reduces the economy of coil caused by line cake quantity increases
Property.
Utility model content
A kind of New-type transformer low tension coil structure proposed the present invention be directed to current this feature.It need not set
Standby input, of low cost, economic and reliable also solve high-power transformer low-voltage coil cake number On The Choice, solve single spiral shell
The line gauge width of spin line circle chooses excessive caused temperature rise of hot spot problem and the line gauge width of double-spiral coil chooses too small cause
Axial bending resistance deficiency problem, while improving product reliability, also improve the economy of product.

Parallel conducting wire 4 is axial in parallel, and parallel conducting wire 1 and parallel conducting wire 2, parallel conducting wire 3 and 4 width of parallel conducting wire are in parallel;When coiling, and
Connection conducting wire 1,2,3,4 is carried out at the same time, and parallel conducting wire 1 and parallel conducting wire 2, parallel conducting wire 3 and parallel conducting wire 4 are in parallel after complete 1 circle
Conducting wire 2 is removed with 4 conducting wire of parallel conducting wire, and parallel conducting wire 1 continues 1 circle of coiling, parallel conducting wire 1 and parallel conducting wire 2 with parallel conducting wire 3
It staggeredly replaces, and cake 3 is risen to from cake 1, parallel conducting wire 3 staggeredly replaces with parallel conducting wire 4, and rises to cake 4, parallel conducting wire 2 from cake 2
1 circle is continued around with parallel conducting wire 1, parallel conducting wire 4 and parallel conducting wire 3, then parallel conducting wire 1 is removed with 3 interior lines of parallel conducting wire, and
Join conducting wire 2 and continues 1 circle of coiling with 4 conducting wire of parallel conducting wire.
