Abstract
The utility model relates to a strong adhesion acetal enameled flat wire which comprises an oxygen-free copper flat wire conductor. The strong adhesion acetal enameled flat wire is characterized in that the outer surface of the oxygen-free copper flat wire conductor is evenly coated with an acetal paint film layer with the thickness of 0.06-0.17mm; and the width of the enameled flat wire is 2-18mm and the thickness of the enameled flat wire is 1-6mm. The strong adhesion acetal enameled flat wire is compact and reasonable in structure; the electric strength and the mechanical strength of a winding wire are greatly improved, and the strong impact of the external environment can be resisted; and an insulation structure is stable and is capable of bearing load generated by the operation of a transformer and the reduction of the ambient environment, so that the service life of a coil can be further improved, and the running safety of the transformer can be improved. The strong adhesion acetal enameled flat wire has the function that due to the strong adhesion of a paint film, the frequency of coil short circuit caused by damage of the paint film can be reduced.
Description
Technical field
The utility model relates to a kind of strong adhesion acetal enameled sheet wire, and especially a kind of winding wire that is used for power transformer winding belongs to coil windings line technology field.
Background technology
In prior art, the traditional production method of acetal enameled sheet wire is to apply acetal paint at the plain conductor outer wall.After enamelled wire coiled coil is used for transformer,, can influence the tack of conductive line surfaces paint film, make paint film be prone to disengaging to take place and cause coil short with conductor owing to the stress that is squeezed, collides, thus reduction transformer useful life and job security.Along with generating set is done bigger and bigger, power transformer voltage and capacity are in the security consideration to power network line simultaneously also along with increasing, will increase substantially with strong adhesion acetal enameled sheet wire demand as power transformer.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the prior art, and a kind of strong adhesion acetal enameled sheet wire is provided, and insulation system is stable, tack is strong, electrical strength is high, mechanical strength is high.
The technical scheme that provides according to the utility model; A kind of strong adhesion acetal enameled sheet wire; Comprise oxygen-free copper lenticular wire conductor, characteristic is: the outer surface at said oxygen-free copper lenticular wire conductor evenly is coated with the acetal paint rete, and the thickness of said acetal paint rete is 0.06～0.17mm.
The width of said enameled sheet wire is 2～18mm, and thickness is 1～6mm.
Said acetal paint rete is applied by polyvinyl formal and obtains.
The utility model compact conformation, reasonable; Electrical strength, the mechanical strength of winding wire significantly improve, and can resist the severe impact of external environment; Insulation system is stable, can bear the load of transformer operation generation and the reduction of surrounding environment, thus the useful life of further extension coil, and the safety in operation of raising transformer.Effect; The strong adhesion of paint film makes because the frequency that the paint film breakage causes coil short to take place.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with concrete accompanying drawing the utility model is described further.
As shown in the figure: strong adhesion acetal enameled sheet wire comprises oxygen-free copper lenticular wire conductor 1, acetal paint rete 2 etc.
The utility model comprises oxygen-free copper lenticular wire conductor 1, evenly is coated with acetal paint rete 2 at the outer surface of said oxygen-free copper lenticular wire conductor 1, and the thickness of said acetal paint rete 2 is 0.06～0.17mm;
The width of said strong adhesion acetal enameled sheet wire is 2～18mm, and thickness is 1～6mm;
Said acetal paint rete 2 is applied by polyvinyl formal and obtains, said polyvinyl formal by polyvinyl alcohol and formaldehyde at H
+The polyvinyl formal that condensation forms under the effect applies and forms.
Said oxygen-free copper lenticular wire conductor 1 by on draw that casting bar five die drawings pull out technology or extruding forms the carrot-free conductor list of any surface finish core; Said acetal paint rete 2 is coated on the periphery wall of oxygen-free copper lenticular wire conductor 1, through curing form fixedly paint film after, again through being drawn to take-up, on coil around the formation finished product.
Adding man-hour, at first be with on draw the casting bar and press through roll and tie to required size, pull out or be squeezed into the carrot-free oxygen-free copper lenticular wire of any surface finish conductor 1 through five die drawings then; Secondly after sealing is softened to lead; Adopt thin lacquer overbrushing technology; And be equipped with suitable stoving temperature with on the smooth fastening perisporium that is coated in oxygen-free copper lenticular wire conductor 1 of acetal paint rete 2, form strong adhesion acetal enameled sheet wire, at last through coil in the traction around.
Apply the acetal paint rete at oxygen-free copper lenticular wire perisporium, under the technology that adopts thin lacquer overbrushing, be equipped with suitable stoving temperature, improve the strong adhesion of paint film, make the fastening coating of acetal paint film, through coiling on the pulling equipment around forming finished product to conductor.
