Abstract
The invention discloses a production method of a transposed winding conducting wire for an environment-friendly reactor, which relates to the technical field of electrical appliances. The production method comprises the following steps: firstly cleaning bare aluminum rods, further forming aluminum wires by extruding the aluminum rods, then coating heat-resistant polyester primers outside the aluminum wires, further coating polyamide-imide finish coats, forming lacquered wires, finally twisting at least five lacquered wires, and winding polyamide-imide outside the twisted lacquered wires. The production method can solve the difficult problems of poor forming compactness of a conductor, difficult treatment of an interface between an insulating layer and the conductor, non-ideal insulation effect and the like in the prior art, and has low cost, high performances and environmental protection, and the product can be widely applied in the industrial and civil fields of track traffic, nuclear power plants, power plants and the like.
Description
Technical field
The present invention relates to technical field of electric appliances.
Background technology
Winding wire is divided into reactor, motor and transformer winding wire by product type.The winding wire of general and reactor, transformer and electric drilling match, all adopt copper material as conductor, electric conductivity is better but cost is too high, and the insulating barrier continuity that is attached to the copper material surface is relatively poor, conductor moulding tightness is poor, insulating barrier and conductor boundary are handled than problems such as difficulties, thereby have influenced numerous performances of product.
Summary of the invention
The object of the invention is to design a kind of good insulating, conduction is stablized the production method of good environmental protection reactor with the transposition winding conducting wire.
The present invention includes following steps:
1) cleaning of naked aluminium bar;
2) the aluminium bar is formed aluminum steel by extruding;
3) outside aluminum steel, apply heat-resistant polyester priming paint after, polyamide coating acid imide finish paint again forms enamelled wire;
4) at least five enamelled wires are stranded, and outside stranded enamelled wire wrapped aromatic polyester acid amides.
The cleaning of described naked aluminium bar is: it is that the speed process with 5-10 rice per minute washes surface impurity and greasy dirt in 5% the sodium hydrate aqueous solution pond that the aluminium bar is soaked in molar concentration; To wash the sodium hydroxide solution that retains with running water through the aluminium bar that sodium hydrate aqueous solution cleaned again, it is stand-by to dry up the back through blow-dry device again.
During wrapped aromatic polyester acid amides, wrapping angle is 30～45 ° in the step 4).
When stranded, the pitch of transposition is 11～17mm in the step 4).
The present invention adopts aluminum material as conductor, makes cost reduce 40-60%, and is convenient to transportation and coiling.The single insulating layer original from product changes composite insulation layer into; the single insulating layer forms netted stereochemical structure after curing; composite insulation layer can have protective effect to the individual layer insulation; the most important thing is that compound insulating barrier can be penetrated in the space network of simple layer; form finer and closely woven space network, thereby reduce the formation of defect point.Insulating barrier adopts the insulating varnish that is beneficial to compound aluminium product, forms good interface between aluminium and insulating barrier, and dielectric strength, mechanical performance and hot property all improve greatly.By many combinations of enameled aluminium flat wire, transposition, make when the reactor coiling, to form closed loop, can reduce the generation of eddy current, also can reduce the heating and the reactive loss of large-scale reactor, thereby increase the service life.The invention solves that prior art conductor moulding tightness is poor, insulating barrier and conductor boundary handle difficult problems such as difficult, that insulation effect is undesirable, low cost, high-performance, environmental protection, product can be widely used in industry, civil areas such as track traffic, nuclear power station, power plant.
Embodiment
Production stage:
1, the cleaning of naked aluminium bar: it is that the speed process with 5-10 rice per minute washes surface impurity and greasy dirt in 5% the sodium hydrate aqueous solution pond that the aluminium bar is soaked in molar concentration; To wash the sodium hydroxide solution that retains with running water through the aluminium bar that sodium hydrate aqueous solution cleaned again, it is stand-by to dry up the back through blow-dry device again.
2, the aluminium bar is formed aluminum steel by extruding: with traditional drawing process is extrusion process, thereby has improved surface smoothness and aluminium material density, thereby has increased current strength; The material crystal structure changes long shape structure into from strip, thereby has improved the mechanical strength of product.
3, outside aluminum steel, apply heat-resistant polyester priming paint after, polyamide coating acid imide finish paint again forms enamelled wire: adopt heat-resistant polyester priming paint, form quality interface with aluminium, finish paint adopts the polyamidoimide lacquer of compact structure, produces the high-quality enamelled wire.
4,5～47 enamelled wires are stranded, and outside stranded enamelled wire wrapped aromatic polyester acid amides: wrapping angle is 30～45 °, the transposition radical be 5～47, the pitch of transposition is 11-17mm.
Product key property and index:
1, conductance: excellent
2, voltage: 2500 volts
3, crooked pliability: 3a3b
4, insulating barrier adhesive force: 15%
5, resilience: 4 °
6, heat shock resistance is more than 200 ℃.
