Abstract
The utility model relates to a polyester-imide transposed conductor for a high-speed train traction transformer. The polyester-imide transposed conductor comprises polyester-imide enameled sheet wires, wherein the polyester-imide enameled sheet wires are combined into two rows of which the wide surfaces are contacted mutually; upper surfaces and lower surfaces of the two rows of polyester-imide enameled sheet wires are transposed along a narrow surface in the same rotation direction; a plurality of insulating layers are continuously and tightly wound outside a transposed enameled wire harness; each polyester-imide enameled sheet wire comprises a copper conductor and a polyester-imide insulating paint layer; the polyester-imide insulating paint layer is circularly coated on the copper conductor; the copper conductor is made of a copper or aluminum sheet wire; and the plurality of insulating layers are made of a plurality of layers of aromatic polyamide insulating paper. The polyester-imide transposed conductor has high mechanical strength, high bending softness and high electrical performance; the temperature resistance level and insulating level of the transposed conductor can be raised; and loss can be reduced.
Description
Technical field
The utility model discloses bullet train traction transformer new special transposed conductor-polyester-imide transposed conductor, specifically be the winding wire that the high-power goods train transformer of 300～380km/h and above passenger train and 7200kW, 9600kW uses, belong to the transformer technology field.
Background technology
Bullet train is sports equipment, and its traction transformer is compared with common transformer, and environment for use is more abominable, shows as that the space is little, temperature is high, vibrations are large.Project organization is also very special: weight wants light, and volume is little, and it is large that ampacity is wanted, and loss is little.Require thus its core product transposed conductor heatproof to want high, it is high that mechanical strength is wanted, and crooked pliability will be got well, and electrical property will be got well.The present speed per hour 300～380km/h of China train traction transformer is with the main dependence on import of transposed conductor.
Summary of the invention
The purpose of this utility model is to overcome existing deficiency, thus the polyester-imide transposed conductor that provides a kind of bullet train traction transformer to use, and this transposed conductor can improve temperature resistant grade, the class of insulation; Good electrical property, and can reduce the wastage.
The technical scheme that provides according to the utility model, the polyester-imide transposed conductor that the bullet train traction transformer is used comprises the polyester-imide enameled sheet wire, described polyester-imide enameled sheet wire is combined into two row that wide face is in contact with one another, on two row polyester-imide enameled sheet wires and below do the same transposition that turns to along leptoprosopy, and the enamel-cover wire harness after transposition outside is closely twined some insulating barriers continuously.
As further improvement of the utility model, described polyester-imide enameled sheet wire comprises copper conductor, polyester-imide insulation enamelled coating, carries out the multi-pass circulation at described copper conductor and scribbles polyester-imide insulation enamelled coating.Described copper conductor adopts copper or flat aluminium wire to make.
As further improvement of the utility model, described polyester-imide insulating varnish layer thickness is 0.09mm～0.13mm.
As further improvement of the utility model, described some insulating barriers are that multilayer aromatics Nomex insulating paper consists of, and thickness of insulating layer is 0.27mm～0.33mm.
Compared with the prior art the utility model has the following advantages:
The utility model mechanical strength is high, crooked pliability is good, good electrical property; Can improve transposed conductor temperature resistant grade, the class of insulation; And can reduce the wastage.
