  • mechanical switching devices so-called short-circuiters, are used, which must meet high requirements. For example, it must be possible for such a short-circuiter to be switched more than 10 times in one hour. In addition, it must withstand a current of 400 A and switch within 250 ms. The actual switching process must be done even faster because within the 250 ms also measured the voltage between the rail and the building earth, compared with a threshold and must be controlled at too high a voltage of the short circuiter.

This is due, among other things, to the fact that the switching device is open as long as the contactor coil is traversed by a current.

Abstract

L'invention concerne un dispositif et un procédé pour limiter le potentiel des rails d'une voie ferrée à courant continu, une ligne de liaison (8) à faible valeur ohmique étant disposée entre le rail (1) et le sol (2) de la structure. Un appareil de commutation (7) intégré dans la ligne de liaison (8) est relié avec une unité de commande (4) par l'intermédiaire d'une liaison de commande, l'unité de commande étant reliée à un voltmètre (3) disposé entre le rail (1) et le sol (2) de la structure. Selon l'invention, l'appareil de commutation (7) comprend une bobine de protection (6) qui est reliée à une unité de commande dynamique (4). Lorsque la tension entre le rail (1) et le sol (2) de la structure dépasse une valeur seuil, l'appareil de commutation (7) effectue une opération de fermeture et connecte la ligne de liaison (8) de manière conductrice.
