Title
(EN) DEVICE FOR HIGH-VOLTAGE ISOLATION OF MEANS FOR SUPPLYING POWER TO ELECTRICAL DEVICE CONNECTED TO HIGH-VOLTAGE POTENTIAL

Abstract
(EN)
A device (40) for high-voltage isolation of a means (30) for supplying power to an electrical device (50) connected to a high-voltage potential comprises an isolation transformer (10) that is suitable for supplying power to the power supply means (30). The isolation transformer (10) is a transformer without a magnetic core and includes a primary inductance means (11a) and a secondary inductance means (11b) that are placed in alignment with each other at a predetermined fixed distance (D) so as to magnetically couple the primary inductance means (11a) and the secondary inductance means (11b), and at least one element (52, 55) that is not sensitive to the magnetic field and that extends through the primary inductance means (11a) and the secondary inductance means (11b). The invention is of particular use on a railway vehicle.

Un dispositif d'isolement haute tension (40) de moyens d'alimentation (30) d'un dispositif électrique (50) connecté à un potentiel haute tension, comporte un transformateur d'isolement (10) adapté à alimenter les moyens d'alimentation (30). Le transformateur d'isolement (10) est un transformateur sans noyau magnétique comprenant un moyen d'inductance primaire (11 a) et un moyen d'inductance secondaire (11 b) disposés en regard l'un de l'autre, à une distance (D) fixe prédéterminée de manière à coupler magnétiquement le moyen d'inductance primaire (11 a) et le moyen d'inductance secondaire (11 b), au moins un élément (52, 55) insensible au champ magnétique s'étendant au travers des moyens d'inductance primaire (11 a) et secondaire (11 b). Utilisation notamment sur un véhicule ferroviaire.
