Description

The oval foil coil of tape insulation tube
Technical field
The utility model relates to a kind of foil coil, relates in particular to a kind of oval foil coil of tape insulation tube.
Background technology
The transformer of elliptical line coil structures has characteristics such as volume is little, in light weight, saving material, obtained using widely in transformer manufacture technology in recent years, yet the transformer of elliptical line coil structures all adopts the flat type copper wire coiling, because loop construction, foil coil are never being used at oval coil.Traditional foil coil is cylinder mode.Its great advantage is that technique for coiling is simple, the production efficiency height, however but can't match with the oval coil of high pressure, be difficult to reach the effect that integral product reduces cost.As not taking measures, the inner and outer diameter of coil is difficult to control during oval paper tinsel coiling coiling, and in coiling after which floor, because the tension force effect of Copper Foil, the outlet copper bar can be caused the coiling failure by horizontal stretch bending.
Summary of the invention
The utility model provides a kind of oval foil coil of tape insulation tube, and this Stability Analysis of Structures is not easy loose and distortion, good heat dissipation effect, and manufacture method is convenient, the rate of finished products height.
The utility model adopts following technical scheme:
A kind of oval foil coil of tape insulation tube, comprise the copper bar of starting, the ending copper bar, insulating cylinder, the Copper Foil of tape insulation paper, the Copper Foil of tape insulation paper is wound on the insulating cylinder layer by layer, the interlayer of the Copper Foil straight line portion of tape insulation paper is provided with the straight line stay, Copper Foil circular arc shaped portion at tape insulation paper is provided with the circular arc stay, stay evenly distributes along the circumference of ellipse, the ending copper bar is connected with the other end of the Copper Foil of tape insulation paper, the copper bar of starting is positioned at the groove of insulating cylinder, and be connected with an end of the Copper Foil of tape insulation paper, have the L shaped steel plate at the copper bar of starting, the L that the copper bar of starting is positioned at the L shaped steel plate bends, and the L shaped steel plate is positioned at the groove of insulating cylinder, and is fixed by groove, when the coiling Copper Foil, bear tension force in the Copper Foil winding process jointly by the L shaped steel plate and the copper bar 1 of starting.
The utility model obtains following technique effect:
(1) insulating cylinder is enclosed within on the winding former during coiling, because insulating cylinder can't be slotted the outlet copper bar is positioned, the baffle plate fluting at pattern tool two ends is spacing, copper bar can be by Copper Foil tension force stretch bending distortion in winding process, therefore before coiling earlier at L shaped steel plate of copper bar underlay, again copper bar is placed on the L of L shaped steel plate curved in, like this, because the restriction that the L of L shaped steel plate is curved makes that copper bar can be by stretch bending, copper bar can not produce distortion in winding process.
(2) for making that heat is easy to shed in the coil use, during coiling, be provided with stay at the interlayer of Copper Foil, it can be dispelled the heat by air.Be not all to need to be set as bar between each layer Copper Foil, only need behind the coil winding of certain number of plies, establish stay, continue coiling again.During coiling since coil be not positive circle, end winding insulation meeting fluffs diffusing in coiling, stop up the coil air flue, therefore when coiling, should will rise with interim small cushion block pad in the first stay of the coil gas gap, to hold the insulation stretching, treat behind the dipping lacquer small cushion block to be taken away, to guarantee the tightness degree of coil-end insulation.
(3) in coiling after which floor, the circular arc of coil and straight line connection part branch be outside bulging deformation gradually, so straight line portion stay air flue height is than the little 1~2mm of circular arc portion.
(4) take apart a die the back because the tension force of coil circular arc portion can make coil long axis direction external diameter diminish, therefore when coiling, each is used about insulating board bed hedgehopping 2mm at the circular arc two ends.
(5) with hold down gag coil overall dimensions positioning instant can be finished coiling behind the mould unloading.
Can be applicable on the range transformer and use as a kind of of low-voltage coil, its electric conducting material can be that Copper Foil also can be an aluminium foil, and insulating material can be selected different insulating material for use according to the different insulative grade.
Because the particularity of loop construction, the place of its uniqueness is arranged during oval foil coil coiling, the utility model is to solve the problem that oval coil exists when coiling.So that coiling goes out qualified oval paper tinsel coiling.
The utility model improves through test of many times, successfully solved the coiling difficult problem of oval (in fact being shaped as similar ellipse) foil coil, the oval coil that coiling goes out satisfies the production needs fully, and this pattern coil has advantages such as volume is little, activity coefficient is high, good heat dissipation effect, economical with materials.
