Description
Technical field
A kind of unlimited dry-type transformer square coil winding structure is the utility model is related to, belongs to Transformer Manufacturing Technology
Field.
Background technology
The open dry-type transformer high-tension coil number of turn is more, typically uses the coiling of cake formula, it is necessary to have positive cake and anti-cake to hand over
For coiling.Because coil is rectangle, the coil winding mould of prior art can only the positive cake of coiling, anti-cake can not coiling；Using
Have a coil winding mould of technology, no matter positive cake and anti-cake using positive cake coiling, it is necessary to be reserved between coil cake compared with big airways, line
Circle size is difficult to control, and coil dimension is bigger than normal, increases transformer main material cost.
Utility model content
The utility model purpose is to provide a kind of unlimited dry-type transformer square coil winding structure, by the coiling of coil
Structure is changed to multistage laminar coiling by cake formula, and laminar coiling is intersegmental to use slant-pull structure, so uniform intersegmental field strength and interlayer
Field strength, ensure to reduce the physical dimension of coil while transformer performance, simplify technique for coiling, solve to deposit in background technology
Above mentioned problem.
The technical solution of the utility model is：
A kind of unlimited dry-type transformer square coil winding structure, it is exhausted comprising insulating cylinder, end insulation, coil and turn-to-turn
Edge, the coil of multiturn are wrapped in outside insulating cylinder, and two ends up and down of coil are provided with end and insulated, and the turn-to-turn of coil is exhausted provided with turn-to-turn
Edge, the coil are multistage laminar winding structure, and the intersegmental of laminar coiling is connected by oblique pull cable architecture.
The oblique pull cable architecture includes lateral conductor one, lateral conductor two, lateral conductor three and lateral conductor four, and the coil is six sections
Laminar winding structure, six sections of wire turns form coils, be respectively A sections wire turn, B sections wire turn, C sections wire turn, D sections wire turn, E sections wire turn and
F section wire turns, connected from beginning to end by lateral conductor one between A sections wire turn and B section wire turns, pass through oblique pull between B sections wire turn and C section wire turns
Line two connects from beginning to end, is connected from beginning to end by lateral conductor three between D sections wire turn and E section wire turns, leads between E sections wire turn and F section wire turns
Lateral conductor four is crossed to connect from beginning to end.
The beneficial effects of the utility model:The winding structure of coil is changed to multistage laminar coiling, laminar coiling by cake formula
It is intersegmental to use slant-pull structure, so uniform intersegmental field strength and interlayer field strength, ensure to reduce coil while transformer performance
Physical dimension, simplify technique for coiling, reduce the window size of iron core, ensure that the practicality of transformer, improve product
Performance, reduce the main material cost of transformer.
