Abstract
In each phase of procedure for mfg. leading and connecting wire, a layer of adhesive material is uniformly coated on outer layer of metal filament, outer layer of conductor and outer layer of insulating sheath. Passing through hot air equipment, the layer of adhesive material is dried, solidified and formed as a layer of very thin protective layer. In procedure of dipping lacquer, the adhesive layer prevents contact between lacquer liquid and metal filament as well as lacquer liquid and layer of insulating sheath so as to prevent cementation, pastiness, chap and breakage.
Description
Technical field
The present invention relates to a kind of electrical equipment and electrical equipment, relate in particular to a kind of electrical equipment and electrical lead wire and manufacturing process thereof.
Background technology
The electrical equipment and electrical lead wire is one of main insulating material of electrical equipment and electrical insulation system, winding is connected by lead wire and external power, need bear whole electric currents of electrical equipment and electrical and whole voltages, if the insulation damages of lead wire or decreased performance will cause the trouble or failure of whole electrical equipment and electrical.
In order to improve the insulation property of electrical equipment and electrical winding, need carry out the dipping lacquer of various process conditions and cure processings (immerse, vacuum pressure impregnation etc.) winding usually, because the needs of technology, lead wire often together carries out dipping lacquer and cures processing with winding.
In order to improve the flexibility of lead wire, the conductor of lead wire is formed through synnema, stranding, pipe strand by many soft filaments usually; The outer layer insulation of lead wire often is made of macromolecule organic materials such as rubber, plastics, silicon rubber.Cure in the process at dipping lacquer, impregnating varnish will produce following harmful effect to lead wire, cause flexibility, insulation property, the conductor contact resistance of lead wire to change:
1, the solvent in the impregnating varnish will be had an effect to the outer layer insulation material of lead wire, cause the insulating material swelling, cause decreasing insulating and inefficacies such as cracking, be full of cracks after the baked and cured;
2, after the impregnating varnish baked and cured with the outer layer insulation secure bond, form the flexibility that one deck paste paint shell has not only influenced lead wire, and easily cause the outer layer insulation cracking after the bending;
3, in the dipping lacquer process, particularly in the vacuum pressure impregnation technical process, impregnating varnish is under pressure or capillarity, lead wire inside is infiltrated in gap along conductor, resin bonds together filament, conductor and insulating sleeve after the baked and cured, make soft originally lead wire become hard, be difficult to bending, can cause insulating sleeve cracking even damaged;
4, at position that impregnating varnish arrives, the all impregnated lacquer in filament surface applies, and not only makes the conductor hardening but also causes the contact resistance between the filament to increase considerably, and be difficult for scraping, when adopting cold-press process, cause the contact resistance of copper sleeve and lead wire to increase.
The problems referred to above of lead wire are prevalent among the electrical equipment and electrical industry, the phenomenon that the motor complete machine that causes owing to lead wire insulation damages, loose contact punctures, generates heat, burns happens occasionally, be major hidden danger and the weak link in the insulation system, had a strong impact on the manufacturability of motor general assembly and the reliability in the actual motion.
Insulation industry and cable industry were taked many ways at the problem of the anti-dipping lacquer of lead wire insulating sleeve, wherein mainly contained: one, at the adhesive of the outside silicon-coating lipid of lead wire insulating sleeve; Two, at the sheath material of the outside extrusion molding of lead wire insulating sleeve, the slim anti-dipping lacquer of parcel one deck.The principle of above method is all based on intercepting contacting of lead wire insulating outer layer and impregnating varnish, to reach the purpose of the anti-dipping lacquer of outer layer insulation.But still there is following drawback in said method:
1, the solvent identical with impregnating varnish (toluene, dimethylbenzene, styrene etc.) of the adhesive of the silicone grease class of uncured processing, the dissolved impregnating varnish that enters of adhesive in the dipping lacquer process has not only weakened antiseized effect, causes the impregnating varnish quality to descend simultaneously;
2, the method for the sheath material of the outside extrusion molding of lead wire insulating sleeve, the anti-dipping lacquer of the parcel very thin type of one deck not only price rise, and cause that the lead wire external diameter increases, flexibility descends, manufacturability is poor;
3, can not solve that the lead wire inner conductor oozes after the lacquer baked and cured in not flexible, the installation process of hardening that the insulating sleeve cracking is damaged, problems such as conductor and insulating sleeve adhesion, the increase of conductor contact resistance.
