Abstract
The utility model discloses a high cold/heat-resisting flat enameled copper wire, wherein the central part of the wire is provided with a flat copper conductor; the middle part of the wire is provided with direct-welding polyester imine paint; the outermost layer of the wire is provided with high cold/heat-resisting insulated paint; and the cross section of the flat enameled copper wire is rectangle. The flat enameled copper wire replaces the traditional process technology of the direct-welding polyester imine flat enameled copper wire and improves the cold-resisting level, the softening puncture property, the hot bonding property, the paint film continuity and the like of a product, thereby not only overcoming the defect of the original product, but also solving the problems of eliminating eddy and skin effect caused by high frequency, reducing the self-heat of the conductor and the like.
Description
The application is one and divides an application that the applying date of original application is on November 4th, 2008, and application number is 2008202206371, and the utility model name is called " high cold-resistant, heat-resisting transformer enameling copper strap wire ".
Technical field
The utility model relates to a kind of high cold-resistant, heat-resisting transformer enameling copper strap wire technology, adopt straight weldering property polyester-imide to coat with lacquer, and cover warnish adopt high cold-resistant, the heat-resisting transformer enameling copper strap wire that height is cold-resistant, heat resistance insulating varnish is made as high cold-resistant, heat-resisting transformer enameled sheet wire internal layer lacquer.
Background technology
At present, directly weldering property polyester-imide enameling copper strap wire structure is by copper conductor, directly weldering property polyester-imide lacquer applies and forms, and is mainly used in the transformer industry.But, because of product thermal endurance class, softening breakdown performance, heat bonding performance, film integrity, freeze-resistant performance etc. do not reach shortcomings such as the requirement of special transformer product and transformer enameled sheet wire self-heating be fast, cause the transformer of special purpose under the ultralow temperature situation, to damage, cause difficulty and economic loss to manufacturing enterprise because of long-time the use.
Summary of the invention
For overcome existing straight weldering property polyester-imide enameling copper strap wire can not effectively guarantee electric enterprise with high-grade special purpose in cold-resistant grade, soften the deficiency of aspects such as breakdown performance, heat bonding performance, film integrity.The utility model provides a kind of high cold-resistant heat-resisting transformer enameling copper strap wire, and it can not only significantly improve the deficiency of existing product, and can eliminate generation eddy current and kelvin effect under the high frequency, reduces problems such as conductor self-heating.
The technical scheme that its technical problem that solves the utility model adopts:
1. utility model solves its technical problem: this novel process The Application of Technology has not only substituted traditional straight weldering polyester-imide lacquer line production technology, and has realized the upgrading of high cold-resistant, heat-resisting transformer enameling copper strap wire product quality.
2. the technical scheme of Cai Yonging: the utility model core is the copper flat conductor, and mid portion is a weldering property polyester-imide lacquer directly, and outermost layer is high cold-resistant, heat resistance insulating varnish, and the global sections shape is rectangle.The utility model is to adopt directly weldering property polyester-imide lacquer enamelled wire internal layer lacquer, and height is cold-resistant, the coating processes technology of a kind of NEW TYPE OF COMPOSITE coating of heat resistance insulating varnish produces cold-resistant, the heat-resisting transformer enameling copper strap wire of high-grade height and cover warnish adopts.
3. shape, the structural feature of utility model design are as follows:
Shape: the cross section is flat square column type insulated conductor.
Structural feature: cold-resistant, the heat-resisting transformer enameling copper strap wire of height centre is that flat copper conductor, intermediate layer are high cold-resistant, heat resistance insulating varnish for straight weldering property polyester-imide lacquer, skin.
4. technological process: carry out being coated with the online first time straight weldering polyester-imide lacquer on the copper conductor surface---evaporation film-forming---online second time, height was coated with cold-resistant, heat resistance insulating varnish------smoke evacuation catalytic purification---cooling, lubricated, take-up---the novel process route of self check packing shipping that evaporates film-forming for the second time
5. the coating processes of composite coating: be that enamelled wire internal layer lacquer adopts original straight weldering polyester-imide lacquer, cover warnish adopts high cold-resistant, heat-resistant agent performance insulating varnish, and two kinds of paint vehicles are organically in conjunction with the compound high-grade enameling copper strap wire that has formed higher cold-resistant grade, softening breakdown performance, heat bonding performance.
Japanning film-forming step: be coated with straight weldering polyester-imide lacquer the online first time---increased behind the evaporation film-forming highly for the second time cold-resistantly freeze, the japanning of solvent resistance insulating varnish, high cold-resistant, the heat-resisting transformer enameling copper strap wire of producing by this novel process.Indexs such as the process test is cold-resistant, thermal endurance class, softening breakdown performance, heat bonding performance, film integrity energy reach the demand of special electric product.
6. main application: high cold-resistant, heat-resisting transformer enameling copper strap wire not only can be applied to electronic apparatus, transformer industry widely, and the application of this technology substituted traditional straight weldering polyester-imide enameled sheet wire production Technology, realized the lifting of high cold-resistant, heat-resisting transformer enameling copper strap wire product quality.This novel process technology can be applied in the Production of Enamel Wires enterprise widely, for market provides better more high cold-resistant, heat-resisting transformer enameling copper strap wire, and raising surface quality and stable performance guarantee, thereby drive the raising of producing enamelled wire industry technology level, filled up domestic blank, popularizing application prospect is extensive in a word, has promotional value and exemplary role.
The beneficial effects of the utility model: enamelled coating has good adhesion property, good high thermal shock resistance properties and good cold-resistant, heat resistance, and can eliminate generation eddy current and kelvin effect under the high frequency, reduce problems such as conductor self-heating.Solved the voltage drop problem of single coating behind the surface-coated lacquer painting layer, can very well adapt to the needs of transformer with enameling copper strap wire.
