Abstract
The invention relates to a copper/silver layered-type corona-resistant transposed conducting wire, in particular to a novel structure of winding wires for AC variable-frequency motors, belonging to the technical field of coil winding wires. The invention is characterized in that the transposed conducting wire is formed through the following steps: coating an oxygen-free copper conductor with a polyesterimide enameled coating, a nano Ag2O compound enameled coating and a polyamidoimide enameled coating in sequence; curing the coatings to form single enameled wires; arranging the single enameled wires into two rows; adding sheathing paper between the two rows of single enameled wires; and coating the sheathing paper in an insulating layer. The invention has the advantages that the structure is compact and reasonable, the space occupied by the transformer is reduced; the adhesive performance of the enameled film to the base material is improved; and the transposed conducting wire has high heat resistance and greatly improves the performance of the winding wires in terms of resistance to the peak voltage surge caused by high-frequency pulse and corona resistance, so that the service life of the AC variable-frequency motor using the winding wires is greatly prolonged.
Description
Technical field
The present invention relates to a kind of copper/silver layered-type corona-resistant transposed conducting wire, specifically a kind of novel alternating-current variable frequency motor winding wire structure belongs to coil windings line technology field.
Background technology
Development along with China's electric machine industry technology, converter technique has obtained using widely with its excellent cost performance, but because the impulse wave that converter technique produces has the crest and the rapid lifting in the section time of high voltage peak, add and to change and high frequency, paint film insulation to winding wire produces greatly influence, it is breakdown to make it that turn-to-turn insulation takes place easily, in addition, the humorous wave energy that frequency conversion produces makes the production of electric energy, transmission and the efficient of utilizing reduce, make winding overheated, produce vibration and noise, and making ageing of insulation, shorten useful life, even break down or burn.Studies have shown that the premature failure of winding wire insulation system is the main cause that causes alternating-current variable frequency motor to damage.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby provide a kind of copper/silver layered-type corona-resistant transposed conducting wire, the resistance of discharge degraded in the time of can effectively increasing electric current by winding wire, eliminate partial discharge, help the accumulation of diffusion charge again, have better heat-resisting and heat conductivity, the dielectric heat of dissipation own effectively reaches the requirement of anti-high-frequency pulse voltage and corona-resistance property etc. rapidly.
According to technical scheme provided by the invention, copper/silver layered-type corona-resistant transposed conducting wire comprises the oxygen-free copper conductor, and feature is: apply polyester-imide enamelled coating, nanometer Ag on the oxygen-free copper conductor successively
2The compound enamelled coating of O, polyamidoimide enamelled coating, boundling solidifies the back and forms single enamelled wire, single enamelled wire is arranged formed two row, and itemizing two adds lining paper between the root enamelled wire, is coated in the paper insulation layer.
Described polyester-imide prime coat thickness of paint layer is: 0.01 ± 0.002mm.
Described nanometer Ag
2The compound enamelled coating of O applies twice at least or more than the twice, the per pass thickness of paint layer is: 0.01 ± 0.001mm.
Described polyamidoimide enamelled coating applies nine roads at least or more than nine roads, the per pass thickness of paint layer is: 0.01 ± 0.002mm.
Compared with the prior art the present invention has the following advantages:
Project organization compactness of the present invention, reasonable has reduced the volume that takies transformer; Strengthened the adhesion property of paint film to basis material; High heat-resisting, significantly improve the performance of winding wire aspect anti-high-frequency impulse peak voltage impact and corona resistance, use extend greatly the useful life of the alternating-current variable frequency motor of this winding wire.
