überwachungsvorrichtung and method for continuous and bahnrückstromfluss independent monitoring of the integrity of the rückleitungsanschlussleiter a returned for the bahnstrom abahnenergieversorungsanlage and rückleitungs system with a re injection and a überwachungsvorrichtung to monitor the integrity of the rückleitungsanschlussleiter of recycling

摘要

the invention relates to a überwachungsvorrichtung and a method for monitoring the integrity of at least two parallel rückleitungsanschlussleitern 6 a returned to thebahnstrom a bahnenergieversorgungsanlage.in addition, the invention relates to a rückleitungs system with a re injection and a überwachungsvorrichtung to monitor the integrity of at least two parallel rückleitungsanschlussleitern 6 of re injection.the erfindungsgemäße überwachungsvorrichtung includes a stromeinspeise facility 7 for feeding a überwachungsstroms with a predetermined frequency to at least one of the at least twoin parallel rückleitungsanschlussleiter 6 and the rückleitungsanschlussleitern 6 assigned sensors 11 for detecting the in the rückleitungsanschlussleitern fluid flow.moreover, the signals of the sensors 11 überwachungsvorrichtung a receiving auswerteeinrichtung 10, such training is that it checks if the sensorsthe rückleitungsanschlussleitern are allocated, the überwachungsstrom with the specified frequency is recorded.a loss of a rückleitungsanschlussleiters 6 or a defective rückleitungsanschlussleiter, due for example to a kabeldiebstahls or kabelbruchs will be closedwhen a sensor 11, a rückleitungsanschlussleiter 6 is attached to the überwachungsstrom with the specified frequency is excluded.
