Description

Technical Field

[0001] The invention relates to the technical field of transposed conductors, and in particular to a reinforced high-temperature-resistant self-adhesive transposed conductor. Background Art

[0002] Transposed conductor is a special electromagnetic wire, which is composed of multiple enameled flat wires. During the winding process, these flat wires are transposed according to a specific rule to form a transposed conductor.

[0003] The utility model with the existing announcement number: CN212570487U discloses a double-sided self-adhesive transposed conductor, including a copper flat wire, which is coated with insulating varnish to form an enameled flat wire, and then a plurality of enameled flat wires are transposed and covered with a transposed conductor insulation layer to produce a single transposed conductor; each of the transposed conductors includes two oppositely arranged wide surfaces and two oppositely arranged narrow surfaces, and the plurality of transposed conductors form two rows with the wide surfaces in contact, and insulating paper is inserted between the two rows of transposed conductors.

[0004] In actual use of the above-mentioned wire, due to the integrated design of the insulation layer on the surface of the wire, the heat dissipation effect of the wire is reduced, the wire temperature increases, and the heat dissipation burden is increased. For this reason, we propose a reinforced high-temperature resistant self-adhesive transposed wire. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a reinforced high temperature resistant self-adhesive transposed conductor, which overcomes the deficiencies of the prior art and aims to solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a reinforced high-temperature resistant self-adhesive transposed conductor, comprising an enameled conductor, the enameled conductors are stacked and distributed in a longitudinal column, the outer wall of the enameled conductors is coated with a self-adhesive paint, the outer wall of the enameled conductors is provided with a plurality of insulating layers, each of the insulating layers is sleeved on the outer wall of the enameled conductor, the outer wall of each insulating layer is provided with a plurality of through grooves, a plurality of the through grooves are uniformly distributed longitudinally on the outer wall of the insulating layer, the outer wall of the insulating layer is further provided with a plurality of through holes, the plurality of through holes extend to the cutouts on both sides of the insulating layer, the insulating layer is made of polyimide, and both sides of the inner wall of the insulating layer are fixedly connected with reinforcing ribs:

[0007] The enameled wire is the main part and has the characteristic of high temperature resistance. Multiple insulation layers are sheathed on the outer wall of the enameled wire. Compared with a single complete insulation layer, it can effectively reduce the damage of the insulation layer after multiple bending. At the same time, the through grooves and through holes opened on the outer wall of the insulation layer can accelerate the heat dissipation of the wire into the transformer oil, increase the heat dissipation area of ​​the wire, and improve the heat dissipation efficiency of the wire.

[0008] The beneficial effect of the present invention is that a plurality of insulating layers are sleeved on the outer wall of the enameled wire, which can effectively reduce the situation where the insulating layer is damaged after multiple bending compared with a single complete insulating layer.

[0009] The present invention can accelerate the heat dissipation of the conductor into the transformer oil by providing the through grooves and through holes on the outer wall of the insulating layer, increase the heat dissipation area of ​​the conductor, and improve the heat dissipation efficiency of the conductor.

[0015] Embodiment 1

[0016] See also Figures 1 to 3 A reinforced high-temperature resistant self-adhesive transposed conductor comprises an enameled conductor 1, which is stacked in a vertical column. The outer wall of the enameled conductor 1 is coated with self-adhesive paint. The outer wall of the enameled conductor 1 is provided with a plurality of insulating layers 2, each of which is sleeved on the outer wall of the enameled conductor 1. The outer wall of each insulating layer 2 is provided with a plurality of through grooves 3, and the plurality of through grooves 3 are uniformly distributed longitudinally on the outer wall of the insulating layer 2. The outer wall of the insulating layer 2 is also provided with a plurality of through holes 4, and the plurality of through holes 4 extend to the cutouts on both sides of the insulating layer 2. The insulating layer 2 is made of polyimide, and both sides of the inner wall of the insulating layer 2 are fixedly connected with reinforcing ribs 5.

[0017] The enameled wire 1 is the main body and has the characteristic of high temperature resistance. A plurality of insulating layers 2 are sleeved on the outer wall of the enameled wire 1. Compared with a single complete insulating layer 2, the insulating layer 2 can be effectively reduced from being damaged after multiple bending. At the same time, the through grooves 3 and through holes 4 provided on the outer wall of the insulating layer 2 can accelerate the heat dissipation of the wire into the transformer oil, increase the heat dissipation area of ​​the wire, and improve the heat dissipation efficiency of the wire.

[0018] Working principle: The through grooves 3 and through holes 4 opened on the outer wall of the insulating layer 2 can accelerate the heat dissipation of the wire into the transformer oil. Since the contact area between the transformer oil and the wire is increased, the heat dissipation efficiency of the wire is improved at this time. In addition, multiple insulating layers 2 are sleeved on the outer wall of the enameled wire 1. Compared with a single complete insulating layer 2, the insulating layer 2 can effectively reduce the damage after multiple bending.
