Abstract

Le dispositif permet de contrôler l'épaisseur de l'isolant selon une certaine direction par rapport à l'axe du fil 4. La poulie 33 est formée d'un flasque en matière isolante et d'un flasque en matière conductrice. Les deux flasques présentent à leur périphérie des rebords de forme tronconique orientés à 45 degrés par rapport au plan perpendiculaire à l'axe de la poulie. Le générateur HF 36 alimente le pont de mesure formé par un condensateur de référence C1 et le condensateur que constituent la poulie 33 et le segment de fil 4 en contact avec la gorge. En faisant passer le fil successivement sur plusieurs poulies agencées différemment, on peut mesurer l'épaisseur d'isolation dans différentes directions radiales par rapport à l'axe du conducteur, les comparer et calculer l'excentricité.The device makes it possible to control the thickness of the insulation in a certain direction relative to the axis of the wire 4. The pulley 33 is formed of a flange made of insulating material and a flange of conductive material. The two flanges have at their periphery edges of frustoconical shape oriented at 45 degrees relative to the plane perpendicular to the axis of the pulley. The HF generator 36 supplies the measuring bridge formed by a reference capacitor C1 and the capacitor formed by the pulley 33 and the segment of wire 4 in contact with the groove. By passing the wire successively over several pulleys arranged differently, it is possible to measure the insulation thickness in different radial directions with respect to the axis of the conductor, to compare them and to calculate the eccentricity.
