SENSOR ARRANGEMENT FOR DETECTING IRREGULARITIES IN OR ON TRACTION CURRENT LINES FOR RAIL-BOUND VEHICLES

摘要

A sensor arrangement for detecting irregularities in or on traction current lines for rail-bound vehicles is proposed, which sensor arrangement comprises at least one sensor (13) for sensing at least one state variable of the traction current line (2), an evaluation unit (14, 15) for evaluating sensor signals which are supplied by the at least one sensor, and a power supply (17) which supplies the at least one sensor and the evaluation unit with voltage and which has a coil (9) for sensing a magnetic field which is generated by a current flowing through the traction current line, and a conversion circuit for converting the current induced by the magnetic field in the coil into storable energy. The at least one sensor, the evaluation unit and the power supply are arranged in a housing (12) which is suitable and is adapted to be a component of a mechanical attachment means of the traction current line such that the magnetic field passes through the coil arranged in the housing.
