Abstract
A composite winding wire for a track traction transformer relates to the technical field of track transportation equipment and comprises at least two composite insulating wires arranged in a total insulating aromatic poly-amide taped covering, wherein each composite insulating wire comprises an aluminum wire core and an aromatic poly-amide insulating layer; and the outside of the aluminum wire core is wound by the aromatic poly-amide insulating layer. By using the composite winding wire, the weight of the track traction transformer product can be reduced, the cost of the track traction transformer product can be reduced and the influence on the distribution of a magnetic field due to the crack of a coil can be avoided. The conductivity quantity of the coil of the composite winding wire is considerably high, so that a single wire cannot bear heavy current, the additional loss generated by a load resistor of the transformer due to the incomplete transposition can be reduced, further the vortex loss can be reduced, the cost is reduced and the energy sources are saved.
Description
Technical field
The utility model relates to the production technical field of the compound winding wire of traction transformer usefulness TUFR in the rail-based conveyor system technical field, particularly rail-based conveyor system.
Background technology
In China city, intercity traffic infrastructure be very weak always, to compare gap obvious with the medium country in the world, differ greatly especially with the distance of developed country, the input of the increasing infrastructure of country's proposition in nearly 2 years is unprecedented to the means of transportation input of big and medium-sized cities.Wherein electrified city rail, inter-city passenger rail, Development of High Speed Railway is rapid, large-scale track traffic facility must be with large-scale electrification as guarantee, thereby driven the rapid intensification in whole rail traction electric machine and traction transformer market, brought the large market with compound winding wire of TUFR and orbit motor with the film sintered winding wire of polyimides-F46 for the track drawing transformer.
At present, orbit motor has formed market scale at home with the film sintered winding wire of polyimides-F46, each big electromagnetic wire factory starts one after another, production capacity at home begins to take shape, and the track drawing transformer is not also all realized production domesticization with the compound winding wire of TUFR, still have the partial dependency import, cost is higher.
The utility model content
The utility model purpose is to design the track drawing transformer compound winding wire of TUFR of a kind of low cost of manufacture, safety.
The utility model comprises and is arranged on insulate at least two compound inslation lines in total lapping layer of aromatic polyamides, and each compound inslation line is made up of an aluminum core and aromatic polyamides insulating barrier, and described aromatic polyamides insulating barrier is wrapped outside the aluminum core.
The utility model adopts the aluminum core to replace the copper core, alleviated the weight of track drawing power transformer product, reduce the cost of track drawing power transformer product, and, aluminium conductor combines with epoxy resin better, when the casting process neutral temperature changed, both coefficients of expansion were very approaching, can not influence Distribution of Magnetic Field because of the coil cracking.Because the product coil electric conduction quantity is quite big, single line can't carry so powerful electric current, the utility model adopts many compound inslation lines to substitute the design of an original insulated wire, reduced the coiling difficulty of transformer, made coil molding simpler, many combination transpositions, the supplementary load loss that transformer load resistance that incomplete transposition causes produces have been reduced, thereby reduced eddy current loss, reduced cost, saved the energy.It is the wrapped materials of two insulation that the utility model adopts the aromatic polyamides insulating barrier, can more stably realize wrapped structure, makes properties of product more stable.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises at least two (this example is four) compound inslation lines 1, and each compound inslation line 1 is made up of an aluminum core 1-1 and aromatic polyamides insulating barrier 1-2, and aromatic polyamides insulating barrier 1-2 is wrapped outside corresponding aluminum core 1-1.
Aromatic polyamides total lapping layer 2 that insulate is set outside four compound inslation lines 1.
Claims (1)
1. the compound winding wire of track drawing transformer, it is characterized in that comprising and be arranged on insulate at least two compound inslation lines in total lapping layer of aromatic polyamides, each compound inslation line is made up of an aluminum core and aromatic polyamides insulating barrier, and described aromatic polyamides insulating barrier is wrapped outside the aluminum core.
