Abstract
The utility model discloses an F-level electromagnetic wire which is low in production cost, is suitable for saving energy and reducing emission, reduces environment pollution and is high in performance. The F-level electromagnetic wire comprises a circular or rectangular copper wire and an insulation resin layer which is formed by extruding and coating high-temperature-resistant modified polyester resin on the copper wire by using am extruder. The insulation resin layer has the thickness of 0.15 to 1.4mm. When the electromagnetic wire is produced, an organic solvent is not needed, the organic solvent is prevented from being discharged, and pollution to environment is eliminated; compared with an enamelled wire, the electromagnetic wire has the advantages that the insulation layer is not needed to be painted for multiple times, baked for multiple times and cured at high temperature; compared with a film lapped wire, the electromagnetic wire has the advantage that a process for manufacturing a film is eliminated; and the power of a heater is only thousands of watts, and at least 200 kilowatt of electricity can be saved. The electromagnetic wire is high in quality, pollution is avoided and zero release is realized in a production process, production efficiency is very high, and energy can be saved greatly. The process is suitable for manufacturing the circular or rectangular electromagnetic wire by using other insulation resins with the characteristic of thermoplasticity.
Description
Technical field
The utility model relates to the technical field that the electrician makes with electromagnetic wire, relates to high-voltage generator, high-tension motor, track drawing motor, frequency-conversion and speed-regulation motor, wind-driven generator etc. with F level electromagnetic wire.
Background technology
In electrician trade, the electromagnetic wire demand is very big.Usually the electromagnetic wire of using in motor, the electrical apparatus industry has two big types: enamelled wire and lapped wire.The amount of solid of wire enamel is very little in the enamelled wire manufacture process, less than 20%, be coated onto certain film thickness, just must be coated with repeatedly, cures repeatedly, makes solvent evaporates and makes film curing.Not only waste a large amount of organic solvents, and caused the severe contamination of environment, repeatedly cured the huge consumption that also causes electric power.Concerning lapped wire; The lapped wire that specific type of electric machines such as particularly large-scale high-voltage generator, high-tension motor, track traffic traction electric machine, high-voltage frequency conversion and speed-adjusting motor are used or mica coiling or polyimide film sintered line; Wherein mica tape or the polyimide film used of lapping electromagnetic wire all used a large amount of organic solvents, and consumed a large amount of electric power, causes waste; Improved the production cost of electromagnetic wire, simultaneously also severe contamination environment.On the other hand, enamelled wire inevitably has pin hole, and the wrapped sintering line of mica lapped wire and film all has seam crossing, and these all are the weak link of electricity undoubtedly on electrical property.Be the high-pressure trend that adapts to high-rating generator, the frequency conversionization of variable working condition high-tension motor, track traffic high speed and heavy loading require electromagnetic wire that higher reliability and long useful life are arranged.
How solving the pollution in the electromagnetic wire production process, the problem of high energy consumption, improve the performance of electromagnetic wire simultaneously, is the technical barrier of this area.
The utility model content
The technical problem that the utility model will solve provide a kind of production cost lower, be suitable for energy-saving and emission-reduction, reduce environmental pollution and the higher F level electromagnetic wire of properties of product.
In order to solve the problems of the technologies described above, the F level electromagnetic wire that the utility model provides comprises: circle or rectangular copper wire and the high temperature resistance polyester resin is extruded in the insulating resin layer on this copper cash through extruder.
Particularly, the thickness of said insulating resin layer is 0.15～1.4mm.
The technique scheme of the utility model is compared prior art and is had the following advantages:
Need not organic solvent when (1) electromagnetic wire of the utility model is produced, stopped the discharging of organic solvent, eliminated pollution environment; Compare insulating barrier with enamelled wire and need not repeatedly to paint, repeatedly cure and hot setting, compare the operation of having saved thin film fabrication with the film lapped wire, heater power has only several kilowatts, and economize on electricity is more than at least 200 kilowatts.So the product quality of the electromagnetic wire of the utility model is higher, production process is pollution-free, zero discharge, production efficiency are higher, can be significantly energy-conservation.The utility model is applicable to other insulating resins with thermoplastic characteristics makes circle and rectangular electromagnetic wire.
(2) the F level electromagnetic wire of the utility model, adopting the high temperature resistance polyester resin is insulating resin, produces F level electromagnetic wire through the technology with extrusion modling.The electromagnetic wire of processing has like this been eliminated the gap of the pin hole and the lapped wire seam crossing of enamelled wire, has improved electrical insulation properties; The high temperature resistance polyester resin is suitable for improving the thermal endurance of insulating barrier, and makes the electromagnetic wire of producing reach the F class F insulation; Conductive coefficient reaches 0.55W/Mk.Thickness of insulating layer can be by regulating in 0.15～1.4mm (two-sided thickness) scope.

Embodiment
The F level electromagnetic wire of present embodiment comprises: circle or rectangular copper wire 11 and the high temperature resistance polyester resin is extruded in the insulating resin layer 12 on this copper cash 11 through extruder.
The thickness of said insulating resin layer 12 is 0.15～1.4mm.
The production method of said F level electromagnetic wire comprises: the high-temperature insulation resin is put into the extruder hopper, start extruder; Said extruder is heated to 180～240 ℃, 260～270 ℃ and 270～275 ℃ to said insulating resin segmentation successively.When pellet reaches 270～275 ℃, be the high temperature viscous state, and be pressed against head; Extrude from the die sleeve mouth annular gap of materials flow through between core rod and die sleeve that arrives head; Make the bare copper wire that is preheated to 110 ℃ pass cross-head and be installed in the shaping mould in the head; The insulating resin that is melt into viscous state is expressed on the bare copper wire that is extruded in circle or rectangle on the bare copper wire; Adopt 85 ℃ hot water, 55 ℃ warm water, 20 ℃ room temperature water to cool off successively then successively 40 seconds; To form the continuous closely knit insulating barrier that thickness is close to bare copper wire uniformly, rolling is to take-up reel the most then.
