Abstract

Aislador pasante de transformador de alta corriente (18) con un medio de sujeción (32) para sujetar en un transformador de una central eléctrica (4) un conductor eléctrico (30, 74, 86) para pasar a través de una carcasa del depósito del transformador (22), y un aislador eléctrico (26) que es guiado alrededor de un conductor (30, 74, 86), donde el conductor eléctrico (30, 74, 86) presenta dos elementos tubulares del conductor (42, 44) guiados uno dentro del otro, caracterizado porque los dos elementos del conductor (42, 44), a lo largo de una vía de circulación de corriente, mediante una interpenetración radial (58, 80, 88), presentan tanto una sección interna (48, 50) dentro del otro elemento del conductor (42, 44), como también una sección externa (46, 52) por fuera del otro elemento del conductor (42, 44), y porque la interpenetración (58, 80, 88) presenta pares de conductores de conexión (90, 92) que se encuentran rotados uno alrededor del otro en dirección axial, entre las secciones internas y externas (46, 48, 50, 52).High current transformer through insulator (18) with a clamping means (32) to hold an electrical conductor (30) in a transformer (30, 74, 86) to pass through a tank housing transformer (22), and an electrical insulator (26) that is guided around a conductor (30, 74, 86), where the electrical conductor (30, 74, 86) presents two guided tubular elements (42, 44) guided one inside the other, characterized in that the two conductor elements (42, 44), along a current flow path, by means of a radial interpenetration (58, 80, 88), have both an internal section (48, 50 ) inside the other conductor element (42, 44), as well as an external section (46, 52) outside the other conductor element (42, 44), and because the interpenetration (58, 80, 88) has pairs of connecting conductors (90, 92) that are rotated around each other in axial direction, in between the internal and external sections (46, 48, 50, 52).
