Description
Technical field
the utility model relates to a kind of enamelled wire, particularly a kind of Special enameled wire.
Background technology
along with the development of electric power, electronic technology, due to variable-frequency motor have energy-conservation, speed governing level is high, structure is simple, volume is little and the advantage such as easy to use, therefore variable-frequency motor all has wide practical use in mine, electric power, transport, household electrical appliances and military project etc., and progressively instead of mechanical speed change and DC speed regulation.But the impulse wave that the speed regulating device of variable-frequency motor produce, in short time, voltage raises rapidly, add transformable frequency, add that the factor such as partial discharge and local dielectric heating creates serious destruction to magnet wire insulation film in addition, enamelled wire structure corona-resistance property is more weak, puncture voltage is not high, shortens the useful life of enamelled wire.And include a lot of enamelled coating in existing enamelled wire structure, each enamelled coating structure is all be made up of a lot of individual layers, but the uneven thickness of each single layer structure, thus causing existing enamelled wire structure ubiquity performance uneven, resistance to elevated temperatures is poor, useful life is short, adhesion property is poor, puncture voltage is not high and the shortcoming such as uneven of being heated.
Summary of the invention
the purpose of this utility model is, provides a kind of Special enameled wire.This enamelled wire structure corona-resistance property is relatively good, and performance is even, and has the advantages such as adhesion property is good, resistance to elevated temperatures is good, long service life, puncture voltage are high and be heated evenly.
the technical solution of the utility model: a kind of Special enameled wire, includes circular copper wire, circular copper wire surface is provided with polyester-imide enamelled coating, polyesteramide imines enamelled coating and polyamidoimide enamelled coating from the inside to the outside successively, is wherein distributed with metal particle in polyester-imide enamelled coating; Polyester-imide enamelled coating is made up of 7 layers of polyester-imide individual layer; Polyesteramide imines enamelled coating is made up of 7 strata esteramides imines individual layers; Polyamidoimide enamelled coating is made up of 10 strata amide imide individual layers, and each thickness in monolayer is all identical, and thickness is: 0.0028-0.0032mm.
aforesaid Special enameled wire, described thickness in monolayer is 0.0030mm.
the beneficial effects of the utility model: compared with prior art, the utility model is structurally by setting gradually polyester-imide enamelled coating from the inside to the outside on circular copper wire surface, the composite insulation layer that polyesteramide imines enamelled coating and polyamidoimide enamelled coating are formed, and to formation polyester-imide enamelled coating, the individual layer number of plies of polyesteramide imines enamelled coating and polyamidoimide enamelled coating limits, the thickness in monolayer forming these enamelled coatings is set as identical numerical value simultaneously, when thickness in monolayer is 0.0028-0.0032mm, this enamelled wire structure corona-resistance property is relatively good, performance is even, and it is good to have adhesion property, resistance to elevated temperatures is good, long service life, the advantages such as puncture voltage is high and be heated evenly.Thus make the resistance of variable-frequency motor wear performance enhancement, extend useful life.In polyester-imide enamelled coating, be evenly distributed with metal particle, improve the adhesion property of polyester-imide enamelled coating to circular copper wire.When the thickness in monolayer forming each enamelled coating is 0.0030mm, the performance of enamelled wire structure is best, and wherein corona-resistance property improves 1.5 times in JB/T10930-2010 standard base; Soften and puncture (DEG C): when 370 DEG C, do not puncture in 2.5min; Puncture voltage residual rate more than 80%; Puncture voltage (KV) more than 12.00, useful life extends 18%; And the thickness in monolayer forming each enamelled coating is set to identical numerical value, thus make enamelled wire when producing, paint convenient, need not often go adjustment coating apparatus to change the thickness in monolayer of each enamelled coating, thus shorten the thickness in monolayer regulation time forming each enamelled coating, improve the production efficiency of enamelled wire, for enterprise brings larger economic benefit.
