Abstract
The utility model discloses a novel varnished wire used for a traction motor. The novel varnished wire comprises a circular copper wire (1). A polyester paint layer (2), a polyester imine paint layer (3) and a polyamidoimide paint layer (4) are successively disposed on the surface of the copper circular wire (1) from inside to outside, the proportion of the polyester paint layer (2) to the polyester imine paint layer (3) and to the polyamidoimide paint layer (4) being 1:6:3. The novel varnished wire used for a traction motor has the characteristics of good adhesiveness, high breakdown voltage and long service life.
Description
Technical field
The utility model relates to a kind of traction electric machine enamelling cuprum round line, particularly a kind of traction electric machine Novel enameled wire.
Background technology
Traction electric machine enamelled wire is that one is mainly applicable to the enamelled wire on High power Traction motor (as mine traction electric machine, metallurgical traction electric machine, track drawing motor, elevator traction motor).Because the condition of part traction electric machine use occasion is more severe, for this has higher requirement to its performance.And that conventional enamelled wire ubiquity tack is poor, the shortcoming such as puncture voltage is not high, and useful life is short.
Utility model content
The purpose of this utility model is, a kind of traction electric machine Novel enameled wire is provided.The utlity model has tack better, puncture voltage is high, the feature of growing useful life.
The technical solution of the utility model: traction electric machine Novel enameled wire, it is characterized in that: comprise copper round wire, described copper round wire surface is provided with polyester enamelled coating, polyester-imide enamelled coating and polyamidoimide enamelled coating from the inside to the outside successively, Polyester Paint layer thickness: polyester-imide thickness of paint layer: polyamidoimide thickness of paint layer=1:6:3.
Aforesaid traction electric machine is with in Novel enameled wire, and described polyester enamelled coating, polyester-imide enamelled coating and polyamidoimide enamelled coating gross thickness are 0.067mm-0.072mm.
Aforesaid traction electric machine is with in Novel enameled wire, and described polyester-imide enamelled coating is made up of 7 road polyester-imide list enamelled coatings, and the thickness of every layer of polyester-imide list enamelled coating is 0.004mm.
Compared with prior art, the utility model forms composite insulation layer by set gradually from the inside to the outside polyester enamelled coating (under-coating varnish), polyester-imide enamelled coating (intermediate layer paint) and polyamidoimide enamelled coating (surface layer paint) on copper round wire surface, limit simultaneously mutual enamelled coating between ratio, make it have tack, puncture voltage is high, useful life is long, chemical property is good, greatly reduce traction electric machine maintenance cost, extend the working life of traction electric machine, good quality assurance is provided.The utility model also limits polyester enamelled coating, polyester-imide enamelled coating and polyamidoimide enamelled coating gross thickness, makes ensureing, in good performance situation, to reduce as much as possible material cost.The utility model also has the following advantages: 1. peel off twisting: K value >=160; 2. pole is reeled: extend 20%, 1d and reel, paint film should be without cracking; 3. puncture voltage (KV): more than 10.00; 4. thermal shock (220 DEG C are extended 20%1d30min): paint film should not ftracture; 5. dielectric loss: 200 DEG C～210 DEG C; 6. resistance to deteriorated: puncture voltage residual rate is more than 70%; 7. resistance to solvent: 6H enamelled coating should not scratched.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Being labeled as in accompanying drawing: 1-copper round wire, 2-polyester enamelled coating, 3-polyester-imide enamelled coating, 4-polyamidoimide enamelled coating.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.Traction electric machine Novel enameled wire, form as shown in Figure 1, comprise copper round wire 1, described copper round wire 1 surface is provided with polyester enamelled coating 2, polyester-imide enamelled coating 3 and polyamidoimide enamelled coating 4 from the inside to the outside successively, polyester enamelled coating 2 thickness: polyester-imide enamelled coating 3 thickness: polyamidoimide enamelled coating 4 thickness=1:6:3.
Described polyester enamelled coating 2, polyester-imide enamelled coating 3 and polyamidoimide enamelled coating 4 gross thickness are 0.067mm-0.072mm.
Described polyester-imide enamelled coating is made up of 7 road polyester-imide list enamelled coatings, and the thickness of every layer of polyester-imide list enamelled coating is 0.004mm.
The high-tenacity polyester under-coating varnish that described polyester enamelled coating adopts ALTS company to produce.Improve the adhesion property of paint film, while preventing from winding the line, occur enamelled coating cracking, come off
The utility model forms composite insulation layer by set gradually from the inside to the outside polyester enamelled coating (under-coating varnish), polyester-imide enamelled coating (intermediate layer paint) and polyamidoimide enamelled coating (surface layer paint) on copper round wire surface, limit simultaneously mutual enamelled coating between ratio, make it have tack, puncture voltage is high, useful life is long, chemical property is good, greatly reduce traction electric machine maintenance cost, extend the working life of traction electric machine, good quality assurance is provided.The utility model also limits polyester enamelled coating, polyester-imide enamelled coating and polyamidoimide enamelled coating gross thickness, makes ensureing, in good performance situation, to reduce as much as possible material cost.
