Abstract
The utility model discloses a mixed wire winding structure of low pressure for having on year accent appearance transformer, its second coil and tertiary winding including the first coil that constitutes by the copper foil, a pair of spiral alternating expression structure that constitutes by paper bag copper ribbon line, place respectively about first coil and second coil, the tertiary winding end at both ends insulating, set up the layer that circles in the forefront and insulating and set up respectively and be in the forefront circles down the copper bar of being qualified for the next round of competitions at both ends, wherein incline including the first coil, the crisscross coiling of second coil and tertiary winding is in the outside, the hybrid wire winding structure that the second coil of this scheme through the spiral alternating expression structure that adopts the first coil that comprises the copper foil and comprise the copper clad ribbon line and tertiary winding are formed, can so that the transformer its when carrying out the conversion of capacity size, conversion efficiency is high just to change the effect steadily to can reduce transformer power consumption effectively.
Description
Technical field
The utility model relates to distribution transformer technical field, refers more particularly to a kind of low pressure mixing winding structure on loaded capacity-regulated transformer.
Background technology
The conversion of the large low capacity of general transformation capacitance-adjustable transformer switches according to the size of load, and high-pressure side is by its connection of D/Y changing of transformation, and low-pressure side is that the connection in series-parallel relation by changing winding realizes.High voltage D connection during triangle Large Copacity, the serial/parallel combination of low pressure, during low capacity, high pressure Y connects, low voltage series.Low pressure must be divided into three parts, could above-mentioned functions be realized.If three parts are stacked up coiling successively, then can produce circulation time in parallel, increase transformer load loss.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of low pressure on loaded capacity-regulated transformer rational in infrastructure, that effectively can slow down transformer load loss to mix winding structure.
For achieving the above object, technical scheme provided by the utility model is: a kind of low pressure mixing winding structure on loaded capacity-regulated transformer, include the first coil be made up of Copper Foil, second coil of the staggered helical formula structure be made up of paper-covered copper flat wire for a pair and tertiary coil, be placed on described first coil and the second coil respectively, the end insulation at the upper and lower two ends of tertiary coil, be arranged on the layer insulation on the first coil and be separately positioned on the outlet copper bar at the described first upper and lower two ends of coil, wherein said first coil is in inner side, second coil and tertiary coil interlock and are wound on outside.
Further, oil duct stay is also placed with in the staggered helical formula structure that described second coil and tertiary coil are formed.
Again further, described oil duct stay presses double helix pattern placement.
Further, to be also wound with one deck half-dried without latitude glass adhesive tape layer in described tertiary coil periphery.
The hybrid winding structure that this programme consists of the second coil and tertiary coil adopting the first coil be made up of Copper Foil and the staggered helical formula structure be made up of wire copper-clad flat line, can make transformer its carry out amount of capacity conversion time, conversion efficiency is high and conversion effect stable, and can effectively reduce transformer efficiency loss.
Accompanying drawing explanation
Fig. 1 is loop construction schematic diagram of the present utility model.
Fig. 2 is plan structure schematic diagram of the present utility model.
Fig. 3 is the winding structure schematic diagram of the utility model coil.
In figure: 1-first coil, 2-second coil, 3-tertiary coil, 4-oil duct stay, 5-layer insulate, and 6-holds insulation, and 7-is half-dried without latitude glass adhesive tape layer, 8-outlet copper bar, 9-profiled insulation cylinder.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail:
Shown in accompanying drawing 1 to 3, a kind of low pressure mixing winding structure on loaded capacity-regulated transformer described in the present embodiment, it includes the first coil 1 be made up of Copper Foil, second coil 2 of the staggered helical formula structure be made up of paper-covered copper flat wire for a pair and tertiary coil 3, be placed on the first coil 1 and the second coil 2 respectively, the end insulation 6 at tertiary coil about 3 two ends, be arranged on the layer insulation 5 on the first coil 1 and be separately positioned on the outlet copper bar 8 at the first coil about 1 two ends, wherein said first coil is in inner side, second coil and tertiary coil staggered (one on the other) are wound on outside.
Concrete, when making the first coil 1, first coiling Copper Foil on profiled insulation cylinder 9, the upper outlet copper bar 8 of Copper Foil beginning position welding, and end insulation 6 is placed at Copper Foil two ends, in the process of coiling Copper Foil, limit is around limit placed layer insulation 5, the upper outlet copper bar 8 of Copper Foil ending welding, finally again around two ring layer insulation 5.
Because the second coil 2 and tertiary coil 3 are double helix alternating expression structure, it is in implementation process: axially and around paper-covered copper flat wire and paper-covered copper flat wire on the first coil 1 that coiling is good, playing first and ending place stays paper-covered copper flat wire and paper-covered copper flat wire will reserve the room of 5mm, the convenient welding gone between.In winding process, end insulation 6 is placed at two ends, and presses double helix pattern placement oil duct stay 4.Coiling limit, limit tightening belt strains coil, after coil winding is good, outermost layer with half-dried without latitude glass adhesive tape layer 7 half-lap one deck.
The examples of implementation of the above are only the preferred embodiment of the utility model, not limit practical range of the present utility model with this, therefore the change that all shapes according to the utility model, principle are done, all should be encompassed in protection range of the present utility model.
