DISJONCTEUR HAUTE TENSION A INSEREUR DE RESISTANCES A LA FERMETURE, NOTAMMENT POUR POSTE BLINDE

摘要

The device includes a main circuit breaking chamber controlled by a sliding control rod. An auxiliary chamber for the insertion of resistances is connected electrically in parallel with the first, and has auxiliary contacts controlled by a second sliding control rod extending parallel to the first rod. A mechanical connection between the two rods secures the two together during the first phase in the closing. The auxiliary contacts are closed before the main contacts. The rods are separated after the closure of the main contacts, subsequently allowing the auxiliary contacts to open under the action of a spring.
