Abstract

The invention relates to an enameled composite wire jacket body. The enameled composite wire jacket body comprises an internal clamping component, wire jackets and external sleeve joint components, wherein the internal clamping component comprises a clamping body with a square section, four walls of the clamping body are each provided with a clamping support, the section shape of each wire jacket is of a regularly octagonal structure, a passage with a square section is arranged inside each wire jacket, a clamping groove is formed in the outer wall of each wire jacket, the wire jackets are fixed to the internal clamping component through mutual matching of the clamping grooves and the vertical supports, and the external sleeve joint components are combined with the outside of the wire jackets in a sleeving mode so that the enameled composite wire jacket body can form an integral whole. The enameled composite wire jacket body is used for an enameled composite wire, and is simple in structure, good in electrical performance, good in stability, safer and more reliable.

Description

technical field [0001] The invention relates to an enamelled combined wire sleeve body. Background technique [0002] With the development of large-capacity power transformers, in addition to improving the mechanical strength, short-circuit resistance and impact resistance of the coil, it is also necessary to reduce the damage of the transformer. Among them, the tip discharge phenomenon is a kind of partial discharge damage to the transformer. Generally, the enamelled combination wire is composed of 2-4 single-sided self-adhesive enameled flat wires radially combined, and is composed of 5 layers of paper insulation layers on the outside, but the conductors of this structure are prone to tip localization at the rounded corners. The discharge phenomenon brings potential safety hazards to the transformer. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an enamelled combined wire sleeve for the enameled combined wir...
