METHOD AND DEVICE FOR MONITORING PANTOGRAPH FAILURE

摘要

The invention relates to a method for monitoring pantograph failure in a rail vehicle combination of at least one rail vehicle, comprising a plurality of pantographs and electrical conductors from the pantographs to a carriage body-side busbar, wherein the surface temperature of at least one electrical conductor from a pantograph to the carriage body-side busbar is determined, an electrical signal corresponding to said temperature is relayed to a carriage control system, and the carriage control system compares the temperatures of the measurement points associated therewith. A failure of a pantograph is recognised by the occurrence of a temperature difference between the measurement points of the affected pantographs and the unaffected pantographs or by the occurrence of a different temperature change speed at the measurement points.
