Description
Technical field
The present invention relates to distribution transformer technical field, more particularly to a kind of low pressure on loaded capacity-regulated transformer
Mixing winding structure.
Background technology
The conversion of general transformation capacitance-adjustable transformer size and capacity is switched over according to the size of load, and high-pressure side is to pass through
D/Y changing of transformations its connections, low-pressure side is realized by changing the connection in series-parallel relation of winding.High voltage D connection during triangle Large Copacity,
The serial/parallel combination of low pressure, high pressure Y connects during low capacity, low voltage series.Low pressure must be divided into three parts, above-mentioned functions could be realized.Such as
Three parts are sequentially overlapped coiling by fruit, then circulation can be produced when in parallel, increase transformer load loss.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided one kind is rational in infrastructure, can effectively slow down transformer
Load loss on loaded capacity-regulated transformer low pressure mix winding structure.
To achieve the above object, technical scheme provided by the present invention is：It is a kind of for low on loaded capacity-regulated transformer
Pressure mixing winding structure, includes the first coil being made up of Copper Foil, the staggered helical formula knot being made up of paper-covered copper flat wire for a pair
Second coil and tertiary coil of structure, it is individually positioned in the first coil and the second coil, the end of tertiary coil upper and lower ends
The layer insulation insulate, being arranged in first coil and the outlet copper bar for being separately positioned on the first coil upper and lower ends, its
Described in first coil in inner side, the second coil and tertiary coil interlock and are wound on outside.
Further, oil duct support is also placed with the staggered helical formula structure that second coil and tertiary coil are constituted
Bar.
Yet further, the oil duct stay is placed by double helix pattern.
Further, tertiary coil periphery be also wound with one layer it is half-dried without latitude glass adhesive tape layer.
This programme is by the staggered helical formula structure that is constituted using the first coil that is made up of Copper Foil and by wire copper-clad flat line
The hybrid winding structure that second coil and tertiary coil are constituted, it is carrying out amount of capacity conversion can to cause transformer
When, high conversion efficiency and conversion effect stabilization, and can be effectively reduced transformer efficiency loss.

Specific embodiment
With reference to specific embodiment, the invention will be further described：
Referring to shown in accompanying drawing 1 to 3, a kind of low pressure on loaded capacity-regulated transformer described in the present embodiment mixes coiling
Structure, it includes the first coil 1 being made up of Copper Foil, the second of the staggered helical formula structure being made up of paper-covered copper flat wire for a pair
Coil 2 and tertiary coil 3, be individually positioned in the coil 2 of first coil 1 and second, the upper and lower ends of tertiary coil 3 end insulation 6, set
Put the insulation of the layer in first coil 15 and be separately positioned on the outlet copper bar 8 of the upper and lower ends of first coil 1, wherein described the
In inner side, the second coil and tertiary coil interlock one coil（One on the other）It is wound on outside.
Specifically, when first coil 1 is made, the coiling Copper Foil first on profiled insulation cylinder 9, in the welding of Copper Foil beginning position
Outlet copper bar 8, and end insulation 6 is placed at Copper Foil two ends, during coiling Copper Foil while around while placed layer insulation 5, Copper Foil ending
Outlet copper bar 8 in welding, finally further around two ring layers insulation 5.
Because the second coil 2 and tertiary coil 3 are double helix alternating expression structure, it is in implementation process：Around for making
Axially and around paper-covered copper flat wire and paper-covered copper flat wire on one coil 1, to rise and stay paper-covered copper flat wire and paper-covered copper flat wire at first and ending
The room of 5mm is reserved, facilitates the welding of lead.End insulation 6 is placed at two ends in winding process, and places oil by double helix pattern
Road stay 4.Coil is tensed with tightening belt in coiling, after coil winding is good, outermost layer is with half-dried without latitude glass adhesive tape 7 half lap of layer
Around one layer.
The examples of implementation of the above are only the preferred embodiments of the invention, not limit implementation model of the invention with this
Enclose, therefore the change that all shapes according to the present invention, principle are made, all should cover within the scope of the present invention.
