Abstract
The utility model discloses a kind of ultra micro thin flat wire of high-power transformer, it is characterised in that：Including copper strap wire (1), the outer surface of copper strap wire (1) is sequentially provided with refractory layer (2), the first insulating barrier (3), the second insulating barrier (4) and wearing layer (5)；The refractory layer (2) is self-cross linking type organic-silicon heat-resisting paint layer, thickness 0.02mm；First insulating barrier (3) is to fill in gram modified poly ester imines enamelled coating, thickness 0.03mm；Second insulating barrier (4) is polyamidoimide enamelled coating, thickness 0.02mm.The utility model has the characteristics of heat shock resistance temperature is high, and cut through temperature is high, and wearability is good.
Description
Technical field
It the utility model is related to a kind of enameled sheet wire, the ultra micro thin flat wire of particularly a kind of high-power transformer.
Background technology
High-power transformer is in order to improve impulse overvoltage performance, widely used new structure and technique, shorted-turn fault
Odds has increased trend.Existing shorted-turn fault mainly includes：Enamel-covered wire is due to heat-resisting, heat shock resistance, soft
Changing the performances such as breakdown not enough causes aging to be accelerated, and insulating properties reduce and cause short circuit；Winding deformation causes machine to enamel-covered wire enamelled coating
Tool wears, and decreasing insulating causes short circuit.Therefore, existing high-power transformer enamel-covered wire heat shock resistance temperature is low, softens and hits
Wear that temperature is low and anti-wear performance is poor.
Utility model content
The purpose of this utility model is, there is provided a kind of ultra micro thin flat wire of high-power transformer.The utility model has
The characteristics of heat shock resistance temperature is high, and cut through temperature is high, and wearability is good.
The technical solution of the utility model：A kind of ultra micro thin flat wire of high-power transformer, including copper strap wire, copper strap wire
Outer surface is sequentially provided with refractory layer, the first insulating barrier, the second insulating barrier and wearing layer；The refractory layer is self-cross linking type organosilicon
Heat-resisting enamelled coating, thickness 0.02mm；First insulating barrier is to fill in gram modified poly ester imines paint, thickness 0.03mm；Described
Two insulating barriers are polyamidoimide enamelled coating, thickness 0.02mm.
In the ultra micro thin flat wire of foregoing high-power transformer, the wearing layer thickness is 0.01mm.
In the ultra micro thin flat wire of foregoing high-power transformer, the copper strap wire broadside is 2.00-2.06mm, and narrow side is
1.06-1.12mm, chamfer radius 0.4mm.
Compared with prior art, the self-cross linking type organic-silicon heat-resisting paint that the utility model priming paint uses being capable of heatproof 250-
500 degrees Celsius, significantly improve the heat resistance of enamelled coating.First insulating barrier is using plug gram modified poly ester imines paint, and it is with second
The insulating lacquer layer of insulating barrier composition has high softening breakdown and thermal shock resistance properties.The wear-resisting enamelled coating of the utility model outermost layer can have
Reduce the damage that mechanical wear is brought to enamelled coating in effect ground.Therefore, the utility model has heat shock resistance temperature high, and softening punctures temperature
The characteristics of degree is high, and wearability is good.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Mark in accompanying drawing for：1- copper strap wires, 2- refractory layers, the insulating barriers of 3- first, the insulating barriers of 4- second, 5- wearing layers.
Embodiment
The utility model is further described with reference to embodiment, but is not intended as to the utility model limitation
Foundation.
Embodiment.A kind of ultra micro thin flat wire of high-power transformer, form as shown in figure 1, including copper strap wire 1, copper strap wire 1
Outer surface be sequentially provided with refractory layer 2, the first insulating barrier 3, the second insulating barrier 4 and wearing layer 5；The refractory layer 2 is self-crosslinking
Type organic-silicon heat-resisting paint layer, thickness 0.02mm；First insulating barrier 3 is plug gram modified poly ester imines paint, and thickness is
0.03mm；Second insulating barrier 4 is polyamidoimide enamelled coating, thickness 0.02mm；The thickness of wearing layer 5 is
0.01mm；The broadside of copper strap wire 1 is 2.00-2.06mm, and narrow side is 1.06-1.12mm, chamfer radius 0.4mm.
Described wearing layer 5 can use imide paint.
