Problems solved by technology

This method partially solves the problem of heat exchange, but there is a problem in covering the transposition wire with a fabric mesh belt impregnated with epoxy resin: the polyester as a component of the fabric mesh belt is hydrolyzable, that is, in the transformer oil , especially at the working temperature of 80-100°C, the polyester material will gradually dissolve or even disappear completely
Therefore, this kind of polyester fiber grid belt is used as a strapping belt, and there are problems in terms of long-term use.

Embodiment Construction

[0022] The present invention is described below in conjunction with some preferred embodiments. It should be noted that these preferred embodiments are not limiting.

[0023] see first figure 1 , which schematically represents a perspective view of the structure of the transposed wire of the present invention; in a preferred embodiment of the present invention, a transposed wire for a transformer is provided, including a first row of enameled wire 1 and a second Rows of enamelled wires 2, each row of the first and second row of enameled wires includes several enameled wires 3, each of the first row of enameled wires 1 passes through the second row of enamelled wires through a bend 4 Conductors, each of the enameled conductors 2 of the second row passes through the enamelled conductors 1 of the first row through another bend 4, thereby realizing the transposition of the enamelled conductors 1 of the first row and the enameled conductors 2 of the second row , wherein the outer...

Abstract

Transposed conducting wire includes first column of enameled conducting wire and second column of enameled conducting wire. There are several pieces of enameled conducting wire in each column. Each piece of enameled conducting wire in first column through a bend and passes through second column of enameled conducting wire. Each piece of enameled conducting wire in second column through a bend and passes through first column of enameled conducting wire so as to realize transposition between first column of enameled conducting wire and second column of enameled conducting wire. In the invention, the transposed conducting wire is covered by fiberglass web. Thus, the conducting wires keep their structure and performance all the time to prevent hydrolysis.

Description

technical field [0001] The present invention relates to a transposed wire (CTC: continuously transposed cable) and its manufacture and use method. This transposed wire is mainly but not limited to be used in large transformers and other electrical equipment such as motors, especially relates to a glass fiber wire Mesh tape transposed wires and methods of making and using the same. Background technique [0002] The outer layer of the traditional transposed wire is covered with insulating paper, which not only affects heat transfer, but also increases the size of the transformer coil. European patent EP 0746 861 B1 discloses a structure in which a fabric mesh tape impregnated with epoxy resin is used to cover transposed wires. The warp and weft of the fabric mesh belt are made of polyester (PE, polyester) or a mixture of glass fiber and polyester (mixed glass silk / polyester). This method partially solves the problem of heat exchange, but there is a problem in covering the tr...
