Device and method for supplying energy to a sensor device in a rail vehicle

Abstract

A device for supplying energy to a sensor arrangement in a rail vehicle. The device has at least one second electrical conductor which has an inductive coupling to a first electrical conductor. The first electrical conductor connects a converter to a motor of the rail vehicle. The device has a switching module which is operated by way of an operating voltage and has the purpose of processing signals of at least one sensor. The at least one sensor serves to acquire data and/or detect a state of a vehicle component. The switching module is connected to a second electrical conductor. The second electrical conductor is configured to generate the operating voltage from an alternating voltage, applied to the first conductor, by way of induction in the second electrical conductor.
