Abstract
The utility model relates to the field of transformer coil production, in particular to a foil type coil free of winding space, which structurally comprises lead ranks, a foil belt and a layer insulator, wherein the two lead ranks are respectively fixedly welded with two ends of the foil belt, and the foil belt and the layer insulator are wound together to form an insulating coil. The foil type coil free of winding space has the advantages of being good in performance, long in service life and the like and can be widely used in the production process of foil type coils.
Description
Technical field
The utility model relates to the transformer coil production field, and a kind of no coiling gap foil coil specifically is provided.
Background technology
Transformer foil coil under the prior art mainly is made up of lead-in wire row, paper tinsel band and layer insulation.Lead-in wire row weld together with argon arc welding with the paper tinsel band, then paper tinsel band, layer insulation (being generally half-dry type DMD or SHS) rolled into insulated coil with speed and get final product on paper tinsel winding mold tool.Yet because the thickness that lead-in wire is arranged is far longer than the paper tinsel band, the lead-in wire row of said structure can expose because of long-term with the space of paper tinsel band weld, and causes the conductor oxidation, influences the superpotential performance of transformer coil useful life and withstand shock.
Summary of the invention
The utility model is the deficiency to above-mentioned prior art, provides that a kind of performance is good, the no coiling gap foil coil of long service life.
The utility model solves the technical scheme that its technical problem adopted: a kind of no coiling gap foil coil; Comprise lead-in wire row, paper tinsel band and layer insulation; Two lead-in wire rows are fixing with the welding of paper tinsel band two ends respectively, and the paper tinsel band twines the formation insulated coil with layer insulation, is characterized in; The position at lead-in wire row two ends is respectively arranged with cross-over block in the insulated coil, and the cross section of cross-over block is a wedge shape.
The material of cross-over block is preferably DMD or SHS.
The cross-over block location can be provided with insulating tape on cross-over block for ease.
Compare with prior art, the no coiling gap foil coil of the utility model has increased cross-over block.The cross-over block that adds has effectively been filled the coiling gap through behind the hot setting; Completely cut off air; Therefore guaranteed the useful life of transformer coil; The superpotential performance of withstand shock is better, mechanical strength is higher, the ability of anti-sudden short circuit is stronger, protection against the tide and decay resistance are more excellent, for the transformer safe operation provides reliable guarantee.
Description of drawings
Accompanying drawing 1 is the structural representation that the utility model does not have coiling gap foil coil;
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further, but not as the qualification to the utility model.
Provide a most preferred embodiment below:
Shown in accompanying drawing 1, the no coiling gap foil coil of the utility model comprises lead-in wire row 1, paper tinsel band 2, layer insulation 3 and cross-over block 4.
Two lead-in wire rows 1 are fixing with the two ends welding of paper tinsel band 2 respectively.Paper tinsel band 2 twines with layer insulation 3 and forms insulated coil.Four cross-over blocks 4 are separately positioned on the position at two lead-in wire rows, 1 two ends in the insulated coil.The cross section of cross-over block 4 is a wedge shape.
The material of cross-over block is DMD or SHS.
The winding process of above-mentioned no coiling gap foil coil is following:
After having wrapped up top layer insulation with prior art; To be placed on the paper tinsel winding mold with the lead-in wire row 1 after 2 welding of paper tinsel band; Before the coil winding, put into and the row of lead-in wire 1 and the general big or small cross-over block 4 in paper tinsel band 2 weld spaces (shown in accompanying drawing 2, utilizing insulating tape 5 location); When guaranteeing tight basically, begin to carry out coil winding; Another lead-in wire row 1 place's the same manner is placed cross-over block 4.Other operation in the winding process is identical with the conventional winding process of prior art.
Above-described embodiment, the utility model embodiment a kind of more preferably just, common variation that those skilled in the art carries out in the utility model technical scheme scope and replacement all should be included in the protection range of the utility model.
Claims (2)
1. no coiling gap foil coil; Comprise lead-in wire row, paper tinsel band and layer insulation; Two lead-in wire rows are fixing with the welding of paper tinsel band two ends respectively, and the paper tinsel band twines the formation insulated coil with layer insulation, it is characterized in that; The position at lead-in wire row two ends is respectively arranged with cross-over block in the insulated coil, and the cross section of cross-over block is a wedge shape.
2. no coiling according to claim 1 gap foil coil is characterized in that cross-over block is provided with insulating tape.
