Along with developing rapidly of power electronic technology and novel semi-conductor device, ac speed control technology obtains constantly improving and improving.The appearance of the frequency converter that performance is progressively perfect, with its good output waveform, the excellent ratio of performance to price makes its market of expand cooperative exchanges speed governing day by day, thereby the ac variable frequency speed regulation motor is used widely; Variable-frequency motor is under high frequency voltage impacts, the discharge of part and the corona phenomenon that space charge gathers easily take place in the insulation of enamelled wire, quickened ageing of insulation, shorten motor useful life, the life-span of many alternating-current variable frequency motor operations has only 1-2, that have in addition have only several weeks so that in trial run the motor enamelled wire just occur damaging, and damage and usually occur in turn-to-turn, that is to say that our common enamelled wire can not satisfy the service condition of our phase asynchronous ac variable frequency speed regulation motor.
Summary of the invention
At the deficiencies in the prior art, the invention provides a kind of production technology of frequency conversion varnished wire, can make enamelled wire obtain good corona-resistance property.
Technical problem to be solved by this invention is achieved by the following technical solution: processing step is as follows: (1) unwrapping wire: the soft attitude copper bar of 2.600mm is up to the standards, is placed on pay off rack porcelain ring vertical lower; (2) wire drawing: 2.600mm copper bar is drawn into required specification silk, makes copper wire line footpath error between+0.013 ,-0.004 scope; (3) clean: will draw good specification silk and cause cleaning water tank place, and clean up with the greasy dirt of the rinse water of handling well with specification silk surface; (4) annealing: cleaned specification silk is annealed 570 ℃ of annealing furnace upper strata temperature, 580 ℃ of lower floor's temperature by the speed of 22m/min from the annealing furnace upper strata by lower floor; (5) cooling: the specification silk with blower cools is come out in the annealing furnace makes it meet the requirements of temperature; (6) japanning, cure, cooling: earlier specification silk surface-coated 10 road frequency conversion polyester are coated with lacquer, according to 1.350,1.360,1.360,1.370,1.380,1.390,1.390,1.400,1.400,1.410 the japanning mould of specification applies successively, apply 3 road polyamidoimide lacquers again, according to 1410,1.420,1.430 the japanning mould of specification applies successively, cure after the per pass japanning, cooling, descend japanning together again, pass through the upper strata from baker lower floor when curing, 220 ℃ of baker inlet temperatures, 330 ℃ of baker lower floor temperature, temperature is 430 ℃ before the catalysis, the supplementary heating temperature is 470 ℃ after the catalysis, evaporate coating the paint internal solvent with above technological temperature, be cured containing admittedly, make the mechanical performance of paint itself, electrical property is given full play to; (7) lubricated: as, to make enamelled wire in the coiling process, can make things convenient for use fully with enamelled wire surface-coated layer of surface lubricant; (8) take-up: the enamelled wire made on the dish tool of client's defined, is made things convenient for client's use.
The production technology of the frequency conversion varnished wire that the present invention adopts can make enamelled wire obtain good corona-resistance property, thereby slow down the ageing of insulation phenomenon, prolongs the useful life of motor.
Embodiment
The production technology of frequency conversion varnished wire of the present invention, processing step is as follows: (1) unwrapping wire: the soft attitude copper bar of 2.600mm is up to the standards, and Interventions Requested are resistance, twisting, resistivity, are placed on pay off rack porcelain ring vertical lower after the check; (2) wire drawing: according to certain wire drawing die proportioning, with 2.555mm, 2.269mm, 2.017mm, 1.794mm, 1.598mm, 1.423mm, the progressively wire drawing of 1.310mm specification wire-drawing die, 2.600mm copper bar is drawn into required specification silk, makes copper wire line footpath error between+0.013 ,-0.004 scope; (3) clean: will draw good specification silk and cause and clean the water tank place, the rinse water that usefulness is handled well cleans up the greasy dirt on specification silk surface etc.; (4) annealing: cleaned specification silk is annealed by lower floor from the annealing furnace upper strata by the speed of 22m/min, 570 ℃ of annealing furnace upper strata temperature, 580 ℃ of lower floor's temperature make its softening performance reach percentage elongation more than 31% after the annealing, below springback angle 37 degree; (5) cooling: the specification silk with blower cools is come out in the annealing furnace, make it meet the requirements of temperature, hand feels not to be felt very boiling hot and gets final product; (6) japanning, cure, cooling: earlier specification silk surface-coated 10 road frequency conversion polyester are coated with lacquer, according to 1.350,1.360,1.360,1.370,1.380,1.390,1.390,1.400,1.400,1.410 the japanning mould of specification applies successively, frequency conversion polyester lacquer is that the form that the nano particle of frequency conversion closes reaction by large fierce dog is dissolved in the middle of the paint of polyester-imide, to obtain good corona-resistance property, apply 3 road polyamidoimide lacquers afterwards again, according to 1410,1.420,1.430 the japanning mould of specification applies successively, coats the polyamidoimide lacquer to reach our needed temperature resistant grade.Cure, cool off the back, descend together to paint again in the per pass japanning, pass through the upper strata from baker lower floor when curing, 220 ℃ of baker inlet temperatures, 330 ℃ of baker lower floor temperature, 470 ℃ of supplementary heating temperature, last fire door blower fan 400r/min after 430 ℃ of the preceding temperature of a catalysis, the catalysis, following fire door blower fan 2000r/min, temperature after the catalysis 〉=650 ℃, circulating fan 2100r/min, waste discharge blower fan 400r/min, evaporate coating the paint internal solvent with above technological temperature, make the mechanical performance of paint itself, electrical property give full play to containing admittedly to be cured; (7) lubricated: as, to make enamelled wire in the coiling process, can make things convenient for use fully with the surface lubricant that enamelled wire surface-coated one deck configures; (8) take-up: the enamelled wire made on the dish tool of client's defined, is made things convenient for client's use.
