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

A kind of New-type transformer low tension coil structure

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.

The technical solution of patent of the present invention is：A kind of New-type transformer low tension coil structure, including coil layer, inner bracing strip, Outer stay, parallel conducting wire；The coil layer includes inner bracing strip and outer stay, the coil layer by alternate combinations copper foil and layer Between insulate and constitute, the inner ring of the inner bracing strip and the outer ring of outer stay are equipped with appearance insulation.

Further, the parallel conducting wire is placed in coil layer, and with width to 2, axial 2 conductor in parallel, 4 cakes are one A unit.

Further, the number of turns of the coil layer is arranged as：The number of turns of the coil layer is arranged as：Parallel conducting wire 1, Parallel conducting wire 2, parallel conducting wire 3,3 circle of coiling in 4 cakes of parallel conducting wire 4；Parallel conducting wire 1, parallel conducting wire 2 and parallel conducting wire 3, 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.

Description of the drawings

Patent of the present invention is described further with reference to the accompanying drawings and examples.

Fig. 1 is the wire turn arrangement schematic diagram of patent of the present invention.

In figure：1- coil layers, 2- inner bracing strips, 3- outer stays, 4- parallel conducting wires 1,5- parallel conducting wires 2,6- parallel conducting wires 3, 7- parallel conducting wires 4.
