Description
One, technical field:
The utility model relates to a kind of silk-covered wire, particularly a kind of high heat conduction terylene single glass fibre copper strap 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.Because China greatly develops power industry recently, particularly hydroelectric development advances by leaps and bounds, the fire-resistant thin dacron glass yarn sintered enameling copper strap wire that hydraulic generator is used still belongs to blank at home, this electromagnetic wire needs the temperature resistant grade of high request, thin insulation thickness, high proof voltage requires and very strong mechanical property.
Three, summary of the invention:
Technical purpose
The utility model provides a kind of novel high heat conduction terylene single glass fibre copper strap wire for solving motor lapped wire heat dissipation problem, and it has good heat-conducting, to satisfy now for specification requirements such as the motor lapped wire are heat-resisting.
Technical problem to be solved in the utility model is to provide a kind of novel high heat conduction terylene single glass fibre copper strap wire, satisfy the temperature resistant grade of the high request that hydraulic generator uses, thin insulation thickness, the demand of the coiling group of high proof voltage requirement and very strong mechanical property.
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 terylene single glass fibre copper strap wire, it comprises conductor, it is characterized in that: described conductor skin is followed successively by layer of silica gel, insulating resin lacquer, single-glass silk, insulating resin lacquer, terylene layer.
Described conductor is a copper strap 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 is an alkali-free glass wool, and closely, wrapped on conductor equably, single-glass silk-covered wire lapping direction is opposite, adopts i.e. 1～2 ° of wrapping angle of fine pith.Glass fiber has the lead of raising intensity, increases flexible effect.
The dacron thread of described terylene layer melts earlier in whole process of preparation and afterwards cools off the effect of playing adhesive glass silk and enameling copper strap wire, so require dacron thread under the temperature resistant grade that guarantees electromagnetic wire, fusing point is low more good more, and require to have good levelability after the fusing, enameled sheet wire, glass fiber and dacron thread are fused into one; And these character of dacron thread depend on the size of the degree of polymerization of dacron thread, in the utility model, the degree of polymerization of described dacron thread is 50～80, optimal proportion described in wrapped between glass fiber and the dacron thread is 35～45%, make dacron thread, can make electromagnetic wire have good electrical property after glass yarn sintered, the favorable mechanical performance is arranged again.
The high heat conduction terylene of the utility model single glass fibre copper strap 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, and cooling is wrapped, japanning is cured, cooling, and the bag terylene, 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
