Detailed Description
For a better understanding of the present invention, reference will now be made in detail to the present invention, examples of which are illustrated in the accompanying drawings.
As shown in fig. 1 and fig. 2, the utility model discloses a winding wire for an energy-saving transformer, which comprises a conductor 1 and an insulating layer coated on the conductor.
The cross section of the conductor 1 is rectangular, and the corners of the rectangle are of convex arc structures.
The insulating layer comprises a first insulating layer 2 and a second insulating layer 3 which are coated on the conductor from inside to outside at a time.
The first insulating layer 2 is formed by a polyimide composite film wrapped on the conductor 1, and the second insulating layer 3 is formed by a mica tape wrapped on the first insulating layer 1.
The corners of the conductor 1 are arranged to be arc-shaped structures, so that the wrapping of the insulating layer is facilitated, and the polyimide composite film has high insulating property. The mica tape has high temperature resistance, combustion resistance and insulativity, and the insulativity and the high temperature resistance of the winding wire for the energy-saving transformer can be improved through the arrangement of the two insulating layers, particularly the arrangement of the mica tape. Can stably work for a long time at the high temperature of 200 ℃ and can bear the high temperature of 240 ℃ for a short time. The method is mainly applied to energy-saving transformers, mining motors and the like.
Specifically, the polyimide composite film is a polyimide F46 composite film, and the mica tape is a 200-grade polyimide reinforced mica tape.
The conductor 1 is formed by winding a plurality of wires. The conductor formed by winding the conducting wire has the advantage of convenient manufacture.
The polyimide composite film is disposed on the conductor 1 by means of sintering. The surface of the polyimide composite film is provided with a polyester-imide glue layer. The polyimide adhesive layer is melted by heating, and then the polyimide composite film can be sintered on the conductor.
The mica tape comprises a mica paper base layer and a polyimide reinforcing layer arranged on the mica base layer. Through the setting of reinforcement layer, can improve the structural strength of mica tape.
The overlapping rate of the mica tape in lapping is 30-50%. Through the overlapping of the mica tape during the lapping, the structural strength of the mica tape lapping can be improved.
The thickness of the conductor is 1mm-8 mm.
The technical principles of the present invention have been described above with reference to specific embodiments, which are intended to explain the principles of the present invention and should not be interpreted as limiting the scope of the present invention in any way. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without any inventive effort, which would fall within the scope of the present invention.
