In this case, the goal is to be achieved, the grinding bars of the pantograph rocker in terms of minimum mechanical wear in a range of limited, minimized contact force to operate without causing interference in the power transmission increased electrical wear due to arcing and sparking.
  • the object is achieved in a device including a sensor device for detecting an operating state of an electrically conductive contact by detecting an electromagnetic radiation in the form of sparks or electromagnetic crackling in response to a contact force at a contact point between a movable and a stationary part of an electrical power supply.

  • a certain contact force between the pantograph 12 and the catenary 20 is required to ensure a safe transfer of energy from the catenary 20 via the pantograph 12 to the vehicle 10 guarantee.
  • This working pressure is achieved by a pilot pressure circuit 40 which is operatively connected to a working pressure control circuit 60, a regulator (not shown) being provided in the pilot pressure circuit 40 to control the working pressure at a regulated pilot pressure.
  • a sensor device 52 is provided on the roof of the vehicle 10 near the pantograph 12 to monitor an operating condition of the contact between the pantograph 12 and the catenary 20, and the parameters measured and evaluated by the sensor device 52 are further passed to a control device. direction 50 headed.
  • a controller 50 is provided to provide control signals to the controller. If a sparking or crackling between the pantograph 12 and the contact line 20 too strong or too large, it can be concluded that the contact is not optimal. This phenomenon is used to determine that the contact pressure of the current collector 12 on the overhead line 20 is either too high or too low. Thus, a contact pressure range is determined as a function of the driving speed or other parameters within which the contact is optimal or acceptable. If the contact force is outside the permissible range, this can be determined and readjusted accordingly.

The parameters obtained by the sensor device 52 are then forwarded to the control device 50 and evaluated by the control device 50 (S2). By the evaluation in S2, the actual force between the pantograph rocker 14 and the catenary 20 is evaluated to be compared with the target force delimited by an upper limit and lower limit (S3).
  • the pilot pressure in the pilot pressure circuit 40 is then readjusted as a function of the evaluation: if the actual force is too small for the current operating situation (ie the actual force is below the lower limit of the desired force), the pilot pressure is increased by the regulator; if the actual force is too large for the current operating situation (ie the actual force is above the upper limit of the desired force), the pilot pressure is reduced by the controller (S4).
