Abstract
A novel transformer coil relates to the improvement of the structure of a transformer, particularly to the improvement of a transfer coil. A low-voltage coil of the transformer takes copper foil as a copper conductor; the copper foil is wound to form a cylindrical layer structure; two ends of the copper foil are respectively welded on the outgoing ends of the coil; insulating layers are wound among the layered copper foil; and insulating blocks are arranged at intervals every a plurality of layers of copper foil. The novel transformer coil adopts the whole copper foil as the copper conductor to replace the traditional conductor, so that the copper foil can be quickly wound on a foil winding device together with the insulating layers, with each layer as a turn, thereby simplifying the winding process of the coil, and improving production efficiency. In addition, the structure eliminates the helix angle at the end part of the coil and improves the resistance of the transformer to sudden short circuit.
Description
Technical field:
The utility model relates to the improvement of transformer device structure, is specifically related to a kind of improvement of transformer coil.
Background technology:
Present low-voltage coil of dry type transformer adopts be multiple conducting wires and around helical winding, the end winding of this structure exists bigger helical angle, can produce bigger leakage field in the end during transformer operation, the anti-sudden short circuit of transformer indifferent.The technique for coiling complexity of this exterior loop, the production cost height, production efficiency is low, has wasted great amount of manpower and material resources.
The utility model content:
The purpose of this utility model provides a kind of novel transformer coil, and it can eliminate the helical angle of end winding, has higher anti-sudden short circuit ability, and the low-voltage coil of dry type transformer that is easy to make.In order to solve the existing problem of background technology, the utility model is by the following technical solutions: low voltage winding in transformers with Copper Foil as copper conductor, Copper Foil is wound into layer structure cylindraceous, the two ends of Copper Foil are welded on the winding protruding head respectively, be wound with insulating barrier together between each layer Copper Foil, and be arranged at intervals with collets every the several layers Copper Foil.
Therefore the utility model can together roll with layer insulation on roll-leaf equipment fast owing to replace traditional lead as copper conductor with whole Copper Foil, and each layer is a circle, has simplified the technique for coiling of coil, has improved production efficiency; This structure has been eliminated the helical angle of end winding in addition, has improved the anti-sudden short circuit ability of transformer.
Description of drawings:
Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the vertical view of Fig. 1.
Embodiment:
Referring to Fig. 1-2, this embodiment is by the following technical solutions: the copper conductor of transformer low voltage device coil is that whole the width and the coil height of Copper Foil 1, Copper Foil is suitable, Copper Foil is rolled into cylindric sandwich construction, the top of Copper Foil and end are welded on the winding protruding head 2 respectively, be wound with insulating barrier simultaneously between each layer Copper Foil, and be provided with dielectric support block 3 every the several layers Copper Foil, form gas channel 4 at interval at Copper Foil, so that heat radiation.Therefore this concrete real-time mode can together roll with layer insulation on roll-leaf equipment fast owing to replace traditional lead as copper conductor with whole Copper Foil, and each layer is a circle, has simplified the technique for coiling of coil, has improved production efficiency; This structure has been eliminated the helical angle of end winding in addition, has improved the anti-sudden short circuit ability of transformer.
