  • FIG 11 shows a basic state of the Fahr effetsschaltersys ⁇ tems 1000. All switches in the signal transmitter 1003 and in the contact line switches 1001a to 1001c are open. The current source 709 in the signal generator 1003 is now turned on. Since it is not loaded by the open current loop, it adjusts itself to its rated voltage. Now the switch 705 is closed and thus sets the first catenary switch 1001a of the current loop under voltage (see FIG 12). This voltage detects the voltage sensor 1005a of the catenary switch 1001a and starts in ⁇ if the same run-up.

  • the control of the catenary ⁇ switch 1001a detects that the current loop by a remote station, that is, the line breaker has been 1001b closed and is thus intact.
  • the startup is completed for station 1001a, leaving resistor 1113a open. That is, in particular, that the switch Ulla is not closed again.
  • an interruption of a cable core and thus of the current loop may show that no current is flowing for a longer period of time than is required for a transmission of a serial data telegram.
  • Such an error affects all stations.
  • the signal generator 1003 can recognize this and report the error. Simultaneously, in particular all stations start a new current loop ramp in beneficial ⁇ manner to achieve that now switched to the terminator before the interruption and a residual-current loop can go into operation.
  • a first indication of a short circuit during operation is a further decrease of the voltage in DATA +, because now only one current has to flow through the small short circuit resistance.
  • the signal generator 1003 can detect this in particular by measuring its output voltage.
  • Another indication of a short circuit or an incorrectly turned terminator from the perspective of the signal generator ⁇ 1003 is the fact that NEN distant stationing are no longer able DATA + to interrupt and transmit data.
  • a third In ⁇ diz for a short circuit may be provided: if the current flow is not interrupted by switching off the corresponding terminating resistor, there must be a short circuit in the Lei ⁇ tion to the next station, because this has yes not yet started its own ramp-up and therefore not switched DATA + and ih ⁇ ren corresponding terminating resistor.
  • the signs or indications described here make it possible to operate the remaining system in the event of a short circuit according to the following procedure.
  • the central unit or the signal transmitter 1003 receives from one station or line breaker 1001a to 1001c no answer, although a current flows, it is based on a short circuit, since a keptfal ⁇ lene station would disrupt the loop.
  • the signal transmitter 1003 itself breaks the current loop by means of its switch 705 until all stations 1001a open to 1001C due to the error in the initial state ge ⁇ hen, ie the switch Ulla to 1111c and the switches 1009a to 1009c are.

  • the stations will break off the DATA + lines 701a again on their own if the current also flows when the terminating resistor is switched on. Since the states ⁇ on has only one contact, ie the switch 1009a or 1009b or 1009c, to interrupt the current loop, it would take it out of the loop and the station behind would have to close its terminating resistor.
  • another separate contact (not shown), for example a relay, is installed at the output of the DATA + line 701a in an advantageous manner, which interrupts only the continuation of the line.
  • a device for controlling and monitoring switching devices which are distributed along a high-voltage line, for example a railway overhead line system.

  • catenary switch, point heater switch and / or short-circuit signaling relays can be electrically connected in series in any combination.
  • any other devices can be electrically connected in series in the electric current loop.
  • it should be devices that need to transfer only a re ⁇ tively small amount of information, particularly some bits, or which can be controlled with only a few bits of control commands.
