Description
One, technical field:
The utility model relates to a kind of silk-covered wire, particularly a kind of high heat conduction single glass fibre flat aluminium wire.
Two, background technology
At present, large, medium and small motor extensive use, motor windings generally is entwined through coil winding machine by glass fiber copper binding wire and the hollow copper strap wire mixing of glass fiber bag, because motor often is in the environment for use of a kind of high temperature or overload, had a strong impact on the reliability and the life-span of motor, so heat dissipation problem is to influence motor performance and vital problem of life-span.It mainly is to cool off by coolant fluid being imported motor stator inside that tradition solves heat dissipation problem, or utilizes the fan heat radiation, or low temperature environment work down.The motor lapped wire itself is studied the increase thermal conductivity, also is one of method that solves motor radiating.At present, used enamel-cover winding wire on the motor is the copper paint envelope curve.Advantages such as the copper paint envelope curve has the conductance height, and resistivity is low.But because the price of copper material is higher, and goes up again in recent years at double, make that the production cost of copper paint envelope curve is higher,, occurred aluminium matter enamelled wire on the market for reducing cost.
Three, summary of the invention:
Technical purpose

Technical scheme
Technical problem to be solved in the utility model can be achieved through the following technical solutions: a kind of high heat conduction single glass fibre flat aluminium wire, it comprises conductor, it is characterized in that: described conductor skin covers layer of silica gel, brushing insulating resin lacquer, wrapped single-glass silk, brushing insulating resin lacquer successively.
Described conductor is a flat aluminium wire, is rectangle, and its long limit is 1.00～4.00mm, and broadside is 2.00～16.00mm.
Described layer of silica gel is a heat conductive silica gel, and thickness is 0.1～0.2mm, directly contacts with conductor can effectively conductor be produced heat and conduct; Heat conductive silica gel has heat conduction, insulation, compression, and adhesion, working temperature are-60～200 ℃, can tolerate 300 ℃ of high temperature, can play the effect of filling, damping, heat radiation.
Described insulating resin lacquer can be preferably the epoxy resins insulation lacquer, preferred especially silk-covered wire lacquer 1448-2; Tack between reinforcing glass silk and the lead.Epoxy resins insulation lacquer, conductive coefficient is 0.21～0.26w/m.k, has anti-load, corona resistance, insulation, excellent mechanical intensity, character such as high temperature resistant.Insulating varnish thickness is 0.02～0.05mm
Described single-glass silk closely, wrapped on conductor equably, adopt i.e. 1～2 ° of wrapping angle of fine pith.Glass fiber has the lead of raising intensity, increases flexible effect.
The high heat conduction single glass fibre of the utility model flat aluminium wire by using crowded-daraf(reciprocal of farad) to draw to the conductor in the middle of the lapped wire, makes the size of conductor reach high accuracy, by unwrapping wire, and annealing, be coated with layer of silica gel, japanning is cured, cooling, wrapped, japanning is cured, and refrigerating work procedure is finished.Whole technology realizes the purpose of this utility model by startup, shut down procedure, the production process control of digital drive establishment.
Beneficial effect
The utility model is by layer of silica gel, and insulating resin coats with lacquer, actings in conjunction such as single-glass silk, and the heat conductivility 0.2～0.3 of raising motor is applicable to various motors, electrical equipment, is particularly useful for the winding of big capacity high motor, electrical equipment.The utility model conductor adopts flat aluminium wire, reduces the finished product of product, alleviates product weight simultaneously.
