| Zusammenfassung: | The selection device has a sensor system arranged for contact-free differentiation between different voltage systems that are joined to an overhead traction line. A control system is provided for selecting a current collector on the basis of the voltage system detected by the sensor system. The sensor system has a capacitive voltage divider with a measurement capacitance. The current collector is part of the capacitive voltage divider, if no contact with the contact wire is provided. Independent claims are included for the following: (1) a method for selecting a current collector; and (2) a rail vehicle with a direct current voltage system.
Es wird ein Vorrichtung zur Auswahl eines Stromabnehmers eines Schienenfahrzeugs vorgeschlagen. Die Vorrichtung umfasst zumindest ein Sensorsystem (100, 110), das eingerichtet ist, zwischen unterschiedlichen an einem Fahrdraht anliegenden Spannungssystemen kontaktlos zu unterscheiden; und ein Steuersystem zur Auswahl eines Stromabnehmers auf Basis des vom Sensorsystem erfassten Spannungssystems. |
