Glass fiber tape film lapping aluminum circular transposition lead

Abstract

The invention relates to a glass fiber tape film lapping aluminum circular transposition lead which has light mass, small transposition pitch, even appearance size, large vortex and circumfluence loss and favorable electrical property. The glass fiber tape film lapping aluminum circular transposition lead comprises a transposition lead core, wherein the outer part of the transposition lead core is lapped by an insulation layer; and the transposition lead core is transposed into two rows by a plurality of film lapping leads. The glass fiber tape film lapping aluminum circular transposition lead is characterized in that the film lapping leads are film lapping aluminum circular leads, and the insulation layer is a film.

Problems solved by technology

[0002] The dry-type air-core filter reactor is installed on the post insulator. The weight of its main body will affect the mechanical strength of the post insulator and the ability to resist other external factors such as wind pressure. In the past, ordinary enamelled copper transposed wires were used. See figure 1 , figure 2 , which is composed of a certain number of enamelled copper flat wires to form two rows in which the wide surfaces are in contact with each other. Covered with self-adhesive varnish 4, the upper and lower sides of the two rows of enamelled flat wires are transposed in the same direction along the narrow surface as required to form a transposed wire core, and then use electrical insulating paper, rope or tape 5 as the external insulation continuous Wrapping, the outermost layer 1 and the innermost layer 3 are overlapped and wrapped, and the remaining layers 2 are wrapped with gaps. The disadvantage is that it uses a copper conductor 6 as the base material, so the quality is large. In order to ensure that the dry-type air-core filter reactor The normal operation of the post insulator needs to increase the volume to ensure the mechanical strength; in addition, limited by the specifications of the ordinary enamelled copper flat wire, the minimum transposition pitch of the ordinary transposed conductor can only reach 45mm, and the transposition times of the transposed conductor are few , the eddy current and circulation loss are large, and because the copper conductor has high mechanical strength and small deformation, the gap between the cores of the transposed wire is large, and it is easy to produce the phenomenon of out-of-tolerance dimensions
