Problems solved by technology

Since wires are usually made into various coils, it is difficult to make the length of each wire consistent in the process of coil winding by using multiple wires and winding them together, which will cause each wire to be wound in parallel. After the coil is formed, the magnetic field strength in the leakage magnetic field is different, so that d

Embodiment 1

[0017] The embodiment of the present invention first discloses a high-frequency wire, including at least two wire bundles, all the enameled wires in each wire bundle are of equal length and arranged in parallel, and the wire bundles are staggered and arranged in a braided form; The number of enameled wires in each wire bundle is the same, and the specification of each enameled wire is the same.

[0018] preferred, such as figure 1 As shown, the number of wire bundles of the high-frequency wire 10 is 2, and the enameled wires in each wire bundle are arranged in a row, and the interlaced twill process of copper braided wires is used for braiding between the two wire bundles. Wherein, the high-frequency wire can be braided into a flat shape by copper braiding process, which is convenient for winding and realizes that when the high-frequency wire is wound into a coil, the parallel winding length is basically the same.

[0019] It is worth noting that the existing copper braided w...

Abstract

The invention relates to the technical field of wires, and discloses a high-frequency wire and a manufacturing method thereof to effectively reduce the loss to the wire caused by high-frequency magnetic field or current and higher harmonics. The high-frequency wire disclosed by the invention comprises at least two wire bundles, wherein all enamelled wires in the wire bundles are equal in length and are arranged in parallel; the wire bundles are transposed in a staggered manner and are arranged in a woven form; and the enamelled wires in the wire bundles are consistent in number and consistent in specification. The invention further discloses the manufacturing method of the high-frequency wire. The method comprises the steps that the sectional area of the enamelled wires, the number of the wire bundles for sharing the current and the number of the enamelled wires in the wire bundles are determined according to performance indexes of the skin effect and the eddy-current loss; the enamelled wires in the wire bundles are equal in length, consistent in number and consistent in specification; and the wire bundles are transposed in a staggered manner and are arranged in a woven form to form the high-frequency wire.

Description

technical field [0001] The invention relates to the technical field of wires, in particular to a high-frequency wire and a manufacturing method thereof. Background technique [0002] Wires usually work under alternating magnetic fields or conduct alternating currents, and sometimes carry many high-order harmonics. In these cases, due to the influence of eddy current effect and skin effect on the wire, the wire will inevitably generate AC electromagnetic loss. The higher the alternating frequency of the magnetic field and current, the greater its loss. In order to solve this problem, reducing the cross-sectional area of ​​the wire is the most effective way to reduce high-frequency loss. We usually use multiple insulated wires connected in parallel. Under the same conductive cross-sectional area, reducing the cross-sectional area of ​​a single wire can effectively reduce the loss caused by high-frequency magnetic field or current and high-order harmonics to the wire. The sma...
