The invention relates to a device that can compensate at the point of origin disturbances of the magnetic field in the surroundings of a railway line caused by fluctuations in the current of the power supply catenary. Said system aims at creating a return circuit whose geometry varies depending on the position of the train and which suppresses at the point of origin the field produced by the catenary-train-track and reduces disturbances in the magnetic field in the surroundings. The system is based on deriving the return current from the track that is divided into elementary segments isolated from one another to a return conductor located adjacent and parallel to the catenary by means of a series of vertical conductors connecting each segment to the return conductor.
L'invention concerne un système de courants de compensation du champ magnétique produit par les chemins de fer à traction électrique, susceptible de compenser les perturbations du champ magnétique aux alentours d'une ligne de chemin de fer dues à des variations de tension de la caténaire d'alimentation. Ce système vise à créer un circuit de retour à géométrie variable en fonction de la position du train servant à supprimer le champ produit par le circuit caténaire-train-voie et à réduire, de ce fait, les perturbations du champ magnétique dans les alentours. Ce système est fondé sur la dérivation du courant de retour depuis la voie divisée en tronçons élémentaires séparés en direction d'un conducteur de retour proche et parallèle à la caténaire via une série de conducteurs verticaux qui connecte chaque tronçon avec ce conducteur de retour.
