Abstract
The invention relates to the technical field of enamelled wires for transformers, in particular to a polyester composite double-insulating enamelled wire for a transformer. The polyester composite double-insulating enamelled wire for the transformer comprises a copper wire conductor, wherein a layer of insulating paint is coated on the copper wire conductor, and a polyethylene terephthalate (PET) polyester film is arranged outside the insulating paint. By adopting the structure, the enamelled wire has polyester composite double-insulating performance and can resist 180-200 DEG C of high temperature, accordingly the insulating performance and the short-circuit capacity are effectively improved, decrustation and damage phenomena of the enamelled wire are avoided in the wire winding process, and the using performance and the service life of the enamelled wire are improved and prolonged. In addition, the polyester composite double-insulating enamelled wire has the advantages of being reasonable in design, simple in structure, low in cost and the like and can be applied to a small power transformer winding with voltage lower than 315kVA and applied in the electrical field of motors with high requirements of high-temperature resistance and the like.
Description
Technical field
The present invention relates to transformer enamelled wire technical field, be specifically related to transformer polyester Composite Double enamel insulated wire.
Background technology
At present, in the transformer technology field, people thirst for solving sudden problem of short-circuit.Transformer not only can cause transformer to damage, burn phenomenon, and can damage other circuit elements devices in use if sudden short circuit.And from the transformer short circuit fault analysis of causes, wherein most important reason is the damage of transformer coil enamelled wire, thereby causes the sudden short circuit phenomenon of transformer.The enamelled wire of prior art, usually scribble one deck insulating varnish in the outside of lead, and the thickness of insulating varnish is 0.02～0.06mm, transformer coil is in winding process, because misoperation occurs the enamelled wire decortication easily, damages phenomenon, perhaps after long-time the use, the insulation property of enamelled wire reduce, and finally cause the generation of sudden short circuit phenomenon, thereby have reduced serviceability and the useful life of product.
Summary of the invention
The transformer of the purpose of this invention is to provide a kind of reasonable in design, simple in structure, good insulation preformance, avoiding occurring peeling, damage phenomenon is with polyester Composite Double enamel insulated wire.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: transformer polyester Composite Double enamel insulated wire, comprise copper conductors, the outside of described copper conductors scribbles one deck insulating varnish, and the outside of described insulating varnish is provided with the PET mylar.
Further, the thickness of described PET mylar is 0.03～1mm.
The present invention has following beneficial effect: transformer of the present invention mainly comprises copper conductors with polyester Composite Double enamel insulated wire, wherein, scribbles one deck insulating varnish in the outside of copper conductors, and is provided with the PET mylar in the outside of insulating varnish; The present invention adopts said structure, make its enamelled wire have polyester Composite Double insulation property, and high temperature resistant is 180～200 ℃, thereby effectively improve anti-insulating properties and the anti-short circuit capability of enamelled wire, avoid in the coiling process, enamelled wire decortication occurs, damages phenomenon, improves product serviceability and useful life.In addition, characteristics such as that the present invention has is reasonable in design, simple in structure, cost is low, but in the following compact electrical transformers winding of extensive use 315kVA and need in the motor electric field of high request such as high temperature resistant.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
The present invention will be further described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, transformer comprises copper conductors 1 with polyester Composite Double enamel insulated wire, and the outside of described copper conductors 1 scribbles one deck insulating varnish 2, and the outside of described insulating varnish 2 is provided with PET mylar 3; Wherein, the thickness of described PET mylar 3 is 0.03～1mm.In the present embodiment, by the PET mylar copper conductors that scribbles insulating varnish is coated, because the PET mylar has high temperature resistant, proof voltage good insulation preformance, and thinner thickness, thereby can make that the anti-short circuit capability of enamelled wire is strong, effectively improve product useful life.The transformer that adopts polyester Composite Double enamel insulated wire to manufacture through test of many times and test, has solved the technical barrier of the sudden short circuit of transformer effectively.
Explanation is at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, other modifications that those of ordinary skills make technical scheme of the present invention or be equal to replacement, only otherwise break away from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of the claim scope of the present invention.
Claims (2)
1. transformer comprises copper conductors (1) with polyester Composite Double enamel insulated wire, it is characterized in that the outside of described copper conductors (1) scribbles one deck insulating varnish (2), and the outside of described insulating varnish (2) is provided with PET mylar (3).
