Gluing process during production of filmed rectangular aluminum stranded wire for extra-high voltage dry type reactor

Abstract

The invention discloses a gluing process during production of a filmed rectangular aluminum stranded wire for an extra-high voltage dry type reactor. The process is characterized by comprising the following step of: getting a stranded, transposed and molded half-finished product and allowing the product to pass through two glue grooves in which thin 118-1H (the viscosity is between 35 and 39S) solvent-free immersion paint and thick 118-1H (D) (the viscosity is between 90 and 110S) solvent-free immersion paint are filled respectively. The process is rational and has ingenious conception; since the thin solvent-free immersion paint can easily pass through gap between filmed round aluminum wires to quickly flow into the half-finished product so as to squeeze the air in the half-finished product out, and the thick solvent-free immersion paint is adhered to the surface of the half-finished product, the thin paint in the half-finished product can be locked, and the paint can be locked by coating polyester nonwoven fabric. After the solvent-free immersion paint and the polyester nonwoven fabric are cured by heat treatment, an insulating layer is formed by the solvent-free immersion paint and the polyester nonwoven fabric together, and a good heat-conducting effect is exerted; and since a conductive solvent is unavailable in the solvent-free immersion paint, the insulation performance between the filmed round aluminum wires can be guaranteed, and the process has extremely high popularization value.

Description

technical field [0001] The invention relates to the technical field of cable equipment, in particular to a production process of a film-wrapped rectangular aluminum stranded wire for a reactor. Background technique [0002] In the past, most UHV reactors were oil-immersed, which had defects such as flammability and poor environmental protection. Therefore, it is imperative to replace oil-immersed reactors with dry-type reactors that are small in size, light in weight, and environmentally friendly. However, there is air between the film-wrapped round aluminum wires in the rectangular film-wrapped stranded transposed aluminum winding wire of UHV dry-type reactor. If it is not removed, the electrical performance of the winding wire will be affected, and the heat dissipation will be poor. . Contents of the invention [0003] The object of the present invention is to provide a gluing process in the production of film-wrapped rectangular aluminum stranded wires for UHV dry-type...
