Abstract
The utility model discloses a 200-grade anti-pulse-voltage composite enameled wire which comprises a copper wire (2). A frequency inverting enamel layer (3) and a polyamide-imide enamel layer (1) are successively arranged on the surface of the copper wire (2) from inside to outside. The frequency inverting enamel layer (3) comprises eight polyester-imide enamel layers. The thickness of each polyester-imide enamel layer is 0.005 mu m. The 200-grade anti-pulse-voltage composite enameled wire has a good corona-resisting performance and prolongs service life of a variable-frequency motor.
Description
Technical field
The utility model relates to a kind of enamelling cuprum round line, particularly a kind of 200 grades of anti-pulse voltage composite enameled wires.
Background technology
Along with the various household electrical appliance such as air-conditioning, refrigerator enter huge numbers of families, " frequency conversion " wording is widely known, and " frequency conversion " the most attracting feature is saves energy.Simultaneously because country's " energy-saving and emission-reduction " policy has brought new opportunity to develop also to bring new challenge simultaneously to energy-saving electric machine industry.
Application variable-frequency control technique, motor has permanent torque, perpetual motion rate governor control characteristics, realizes controllable initiating, stops, braking again; system configuration is simple, small investment, and volume is little; function is strong; can carry out easily voluntarily and control, and the 30-40% that can economize on electricity, popularize variable-frequency control technique to improving the level of China's modernization of industry; energy savings; save material, protection of the environment has very important significance, and variable-frequency control technique will progressively replace mechanical speed governors and DC speed regulation.Along with the rapid popularization of variable-frequency control technique, become increasingly conspicuous its useful life.
And a lot of conventional frequency converters usually only have one deck insulating varnish, the transient pulse ripple that it causes can cause electrical machine insulation to have problems, resonant pulses ripple also appears in the wiring between motor and frequency converter at any time, be that usually said corona discharge or partial discharge effect occurs, partial discharge from reducing the insulation of winding wire, thereby As time goes on can shorten life-span of motor.
Utility model content
The purpose of this utility model is, a kind of 200 grades of anti-pulse voltage composite enameled wires are provided.The utlity model has good corona-resistance property, improved the useful life of variable-frequency motor.
The technical solution of the utility model: 200 grades of anti-pulse voltage composite enameled wires, it is characterized in that: comprise copper round wire, described copper round wire surface is provided with frequency conversion enamelled coating and polyamidoimide enamelled coating from the inside to the outside successively, described frequency conversion enamelled coating is to comprise 8 road polyester-imide enamelled coatings, and the thickness of per pass polyester-imide enamelled coating is 0.005um.
Compared with prior art, the utility model adopts the compound frequency conversion enamelled coating being made up of the 8 anti-pulse voltage in road (anti-corona) polyester-imide enamelled coatings of polyamidoimide enamelled coating, polyester-imide frequency conversion enamelled coating has good pliability tack, can meet the processing technology that client is different, after composite polyamide acid imide enamelled coating, make again the hot property of product, chemical property be improved, finally there is good corona-resistance property, improved the useful life of variable-frequency motor.The utility model is compound by concrete frequency conversion enamelled coating structure and the polyamidoimide enamelled coating limiting, and makes the utlity model has following performance: 1. extend 20%, 1d and reel, paint film should be without cracking; 2. puncture voltage (KV) is more than 11.00; 3. thermal shock (220 DEG C of 1d 30min) paint film should not ftracture; 4. softening puncturing (DEG C) do not puncture in 370 DEG C of 2min; 5. resistance to deteriorated: puncture voltage residual rate is more than 70%; 6. corona resistance ability corona time >=200min; 7. heat resisting temperature can reach 200 DEG C.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Being labeled as in accompanying drawing: 1-polyamidoimide enamelled coating, 2-copper round wire, 3-frequency conversion enamelled coating.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.200 grades of anti-pulse voltage composite enameled wires, form as shown in Figure 1, comprise copper round wire 2, described copper round wire 2 surfaces are provided with frequency conversion enamelled coating 3 and polyamidoimide enamelled coating 1 from the inside to the outside successively, described frequency conversion enamelled coating 3 is to comprise 8 road polyester-imide enamelled coatings, and the thickness of per pass polyester-imide enamelled coating is 0.005um.
The diameter of described copper round wire 2 is 1.240～1.255mm, and the insulation enamelled coating minimum thickness that frequency conversion enamelled coating 3 and polyamidoimide enamelled coating 1 are compounded to form is 0.067mm.
The utility model adopts the compound frequency conversion enamelled coating being made up of the anti-pulse voltage of multiple tracks (anti-corona) polyester-imide enamelled coating of polyamidoimide enamelled coating, polyester-imide frequency conversion enamelled coating has good pliability tack, can meet the processing technology that client is different, after composite polyamide acid imide enamelled coating, make again the hot property of product, chemical property be improved, finally there is good corona-resistance property, improved the useful life of variable-frequency motor.
