Transformer Winding
Technical field
The utility model relates to a kind of Transformer Winding, particularly relates to a kind of winding for high-tension transformer.
Background technology
Existing Transformer Winding kind is a lot, and general Transformer Winding is made up of skeleton, former limit winding, secondary winding, and in the time that former limit winding conducting wire wire diameter is larger, its effect is that loss is large, heating causes coil to burn out.
Utility model content
For the deficiency of above-mentioned Transformer Winding, the utility model provides a kind of cost low, and structural design is new reasonable, and loss is little, good insulating, the Transformer Winding that efficiency is high.
Technical solution of the present utility model:
Transformer Winding, it comprises former limit winding, secondary winding, skeleton, insulating paper, it is characterized in that: described skeleton is rectangular configuration, and two ends are provided with square resin plate, in the middle of skeleton, has square through hole, four limits of square resin plate are respectively provided with an aeration structure; Described former limit winding is the enamelled wire winding of selected good wire diameter, the number of turn, and around on skeleton, described secondary winding is the enamelled wire of selected good wire diameter, around former limit winding skin, every interlayer separates with insulating paper, be so both conducive to layer with layer insulation, be conducive to again the heat radiation of transformer.
Described aeration structure is rectangular opening.
Described rectangular opening is at least arranged everywhere on square resin plate.
Described rectangular opening is entrance hole and the wire hole of former limit winding and secondary winding, and in addition, this rectangular opening also has thermolysis.
Described insulating paper is high pressure resistant, resistant to elevated temperatures paper.
The beneficial effects of the utility model:
The utility model by arranging aeration structure on Transformer Winding skeleton, this aeration structure not only can be used as entrance hole and the wire hole of former limit winding and secondary winding, but also there is thermolysis, between winding by insulating paper separate be conducive to layer with layer insulation, that this Transformer Winding has is high pressure resistant, high temperature resistant, loss is little, steady performance.

Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is further described.
Transformer Winding as described in Fig. 1 to 2, it comprises former limit winding 5, secondary winding 6, skeleton 1, insulating paper, and described skeleton 1 is rectangular configuration, and two ends are provided with square resin plate 3, in the middle of skeleton 1, have square through hole 2,3 four limits of square resin plate are respectively provided with an aeration structure, described former limit winding 5 is selected good wire diameters, the enamelled wire winding of the number of turn, around on skeleton 1, described secondary winding 6 is enamelled wires of selected good wire diameter, around former limit winding 5 skins, every interlayer separates with insulating paper, so both be conducive to layer with layer insulation, be conducive to again the heat radiation of transformer, described aeration structure is rectangular opening, described rectangular opening is at least arranged everywhere on square resin plate 3, described rectangular opening 4 is entrance hole and the wire hole of former limit winding 5 and secondary winding 6, in addition, this rectangular opening 7 also has thermolysis, described insulating paper is high pressure resistant, resistant to elevated temperatures paper.
Specific works process:
Pressing the enamelled wire of selecting wire diameter on skeleton, fix the two ends of coil windings and winding, the two ends of winding respectively the rectangular opening from the both sides resin plate of skeleton wear out, and reserve sufficient length, end of incoming cables and leading-out terminal are respectively divided into several shallow bids and load onto plug-in unit.Former limit winding, the enamelled wire of selected wire diameter,, is set to former limit winding on magnetic core cylinder beyond on the skeleton of former limit and fix the two ends of coil windings and winding by definite number of turn.Secondary winding, the enamelled wire of selected wire diameter, on secondary skeleton, often winds one deck by definite number of turn, encloses and fixes with the paper bag one that insulate, until around complete secondary coil, fix insulating paper and coil two ends.The secondary winding winding is set on the cylindrical edge of another one magnetic core.Being housed, former limit winding installs with two magnetic core clips that secondary winding is housed, finally the Transformer Winding casting resin assembling.
The utility model by arranging aeration structure on Transformer Winding skeleton, this aeration structure not only can be used as entrance hole and the wire hole of former limit winding and secondary winding, but also there is thermolysis, between winding by insulating paper separate be conducive to layer with layer insulation, that this Transformer Winding has is high pressure resistant, high temperature resistant, loss is little, steady performance.
To sum up, the utility model accomplishes the end in view.
