Abstract
The utility model relates to a single-sided self-adhesive polyvinyl acetal enameled composite wire, in particular to a winding wire used in electric high voltage transformer coil, and belongs to the technical field of coil winding. The utility model is characterized in that a vinyl acetal insulating enamel layer is coated on external surface of the metal wire, and a self-adhesive enamel layer is coated on the wider side of the vinyl acetal insulation enamel layer. The utility model has the advantages of simple, impact and reasonable structure; capability for preventing the leakage of excessive self adhesive enamel from impacting the normal application of a transformer; capability for melting the self adhesive layer on the wider side of the wire, adhering the self adhesive layer between every two circles, cooling, and solidifying at the adhering position to form a whole by the inter-circle adhesion, thereby improving coil rigidity and resistance to deformation; and capability for improving the operational safety of the transformer and prolonging service life.
Description
Technical field
The utility model relates to a kind of single side self acetal enameled sheet wire, and the winding wire of power transformer high-tension coil use specifically belongs to coil windings line technology field.
Background technology
In prior art, the traditional production method of self-adhesion acetal enameled sheet wire is to be coated with the self-adhesion lacquer after being coated with acetal paint on the plain conductor again, and after the enamelled wire coiled coil heats, lead is gone up too much self-adhesion lacquer on four sides and overflowed, make winding deformation easily, thereby influence the trouble free service and the useful life of transformer.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of single side self acetal enameled sheet wire, can allow self-adhesive layer on the lead broadside single face melt and do not overflow, can intensifier coil rigidity and non-deformability, and can improve the space availability ratio of winding.
Main solution of the present utility model is achieved in that
The utility model mainly comprises plain conductor, acetal insulation enamelled coating, self-adhesion enamelled coating, and feature is that described plain conductor outside is coated with acetal insulation enamelled coating, is coated with the self-adhesion enamelled coating on outer wide the single face of acetal insulation enamelled coating.Described self-adhesion enamelled coating width should be apart from acetal each the 1～2mm of enamelled coating broadside both sides that insulate.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Can avoid too much self-adhesion lacquer to overflow, influence effective use of transformer; Can allow self-adhesive layer on wide single face of lead melt and bonding at every turn-to-turn, treat the coil cooling after, the bonding place transfers solid state to, coil has reached the effect of intensifier coil rigidity and non-deformability by integral body of the bonding formation of turn-to-turn; Can improve the safety in operation of transformer, and can increase the service life.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly is made up of self-adhesion enamelled coating 1, plain conductor 2, acetal insulation enamelled coating 3 etc.Described plain conductor 2 outsides are coated with acetal insulation enamelled coating 3, are coated with self-adhesion enamelled coating 1 on acetal insulation enamelled coating 3 outer wide single faces, and self-adhesion enamelled coating 1 width should be apart from acetal insulate wide both sides of enamelled coating each 1～2mm, coiled coil again.
Keep closely contact between each conductor turns during the utility model coil winding, make plain conductor 2 heatings then, allow self-adhesive layer on the lead broadside single face melt and bonding at every turn-to-turn, after treating the coil cooling, the bonding place transfers solid state to, coil has reached the effect of intensifier coil rigidity and non-deformability by integral body of the bonding formation of turn-to-turn.
