Abstract

The invention provides a terylene glass-fiber covered sintered enamelled wire. According to the terylene glass-fiber covered sintered enamelled wire, an insulation layer has uniform thickness, is smooth in surface and high in flexibility, has high breakdown voltage, and can meet the use requirement of a transformer or a motor. The terylene glass-fiber covered sintered enamelled wire comprises a conductor and the insulation layer wrapped outside the conductor, and is characterized in that the insulation layer includes a terylene glass-fiber coating and an insulating paint layer.

Description

Dacron glass yarn bag sintering enamelled wire

Technical field

The present invention relates to the glass fiber covered wire field, be specially dacron glass yarn bag sintering enamelled wire.

Background technology

The insulating barrier 4 that present glass fiber covered enamelled wire comprises conductor 1 and is coated on the conductor outside, see Fig. 1, wherein insulating barrier 4 is the mixed layer of glass fiber and insulating varnish, insulating barrier is to obtain at the wrapped impregnating varnish that applies in the conductor external procedure of glass fiber, its shortcoming is: can have larger gap between glass fiber and the conductor when adopting the wrapped conductor of glass fiber outside, and can only play bonding effect at the wrapped impregnating varnish that applies simultaneously of glass fiber, this is so that there is pore in insulating barrier, rough, and its thickness of insulating layer reaches 0.4mm～0.5mm, thickness of insulating layer is thicker, size is inhomogeneous, cause the enamelled wire pliability poor, breakdown potential is forced down, adopt the transformer of this glass fiber covered enamelled wire winding or motor in use the office of being prone to put phenomenon, affect the useful life of transformer or motor, thereby it can not satisfy the instructions for use that is pressed with transformer or the motor of strict demand for dimensional homogeneity and breakdown potential.

Summary of the invention

For the problems referred to above, the invention provides dacron glass yarn bag sintering enamelled wire, its thickness of insulating layer is evenly, smooth surface, flexility is good and have higher puncture voltage, can satisfy the instructions for use of transformer or motor.

Its technical scheme is such, and it comprises conductor and insulating barrier, and it is outside that described insulating barrier is coated on described conductor, it is characterized in that: described insulating barrier comprises dacron glass yarn covering and insulation enamelled coating.

It is further characterized in that:

It is whole that described dacron glass yarn covering is coated on described conductor, and it is outside that described insulation enamelled coating is coated on described dacron glass yarn covering.

It further is characterised in that: described dacron glass yarn covering adopts high-frequency induction heating technique with the dacron glass yarn sintered described conductor outside that adheres to; It is outside that described insulation enamelled coating adopts felt method or die methods that insulating varnish is coated in described dacron glass yarn covering equably.

In the dacron glass yarn bag sintering enamelled wire of the present invention, its insulating barrier comprises dacron glass yarn covering and the outer field insulation enamelled coating of internal layer, and its internal layer adopts high-frequency induction heating technique with the dacron glass yarn sintered conductor outside that adheres to, thereby can effectively reduce the space between conductor and the insulating barrier and can not produce pore, adopt simultaneously die methods or felt method enamelling process can strictly control the enamelled wire size, insulating varnish is coated on the dacron glass yarn covering equably outside, further guaranteed the uniformity of size, therefore dacron glass yarn bag sintering enamelled wire of the present invention has good pliability and thermal endurance and higher puncture voltage, and total thickness of insulating layer is less, only be about 0.3mm, can reduce the space when being applied to transformer or motor, and be conducive to the heat conduction, guarantee afterwards the performance and used life of transformer or motor.
