Abstract
The invention relates to a monitoring device for de-energized catenary systems having bearer cables, contact wires and droppers as well as earthing lines, overhead lines and cable systems. The aim of the invention is to create a monitoring device for de-energized catenary systems or overhead lines during new construction or servicing work to counter theft, which is as easy to implement as possible and additionally can be installed quickly and enables the monitoring of predetermined track sections. Said aim is achieved by dividing catenaries or overhead lines or cable systems into segments (S1-Sn), each consisting of two parallel strands, by forming a line resistance (RFL) at one end by short-circuiting the strands of each segment, by each of the free ends of the segments (S1-Sn) with a respective measuring resistor (RM) of a predetermined size and a respective voltage source (VDC) being connected to form a respective closed circuit (SK1-SKn), and by each circuit being connected to a measuring unit (MV) for measuring the loop current that is equipped with a monitoring device (UE) for triggering an alarm of an alarm device (AL) when a predetermined limit value is exceeded or the loop current is interrupted.
