Circuit arrangement for indication of contamination of railway rail tops and method of such indication

摘要

the involvement of the indication zneciu0161tenu00ed running u017eeleznicnu00edch tracks, just poju00edu017edenu00e9ho railway section in the drive (d), contains in this rail section by a track circuit (tc).which contains the first track belt (1rb), the second track belt (2rb) and the power supply end (fe) and tracker (r).for rolling a strip (1rb, 2rb) poju00edu017edu00ed the traction vehicle (mv) train with the first dvoukolu00edm (1tw), at least one power dvoukolu00edm and in at least one subsequent dvojkolu00edm (ntw).the power end (fe) track circuit (tc) has a first output (fe1) pripojen in series with the first track zones (1rb)in series with the priju00edmacem (r), and also in series with the second track zones (2rw) to the second output (fe2) supply end (fe).in the first bezprostrednu00edm wheelset (1tw) and / or at least one subsequent wheelset (ntw) is a localized current cidlo (1cd, ncd), whose output is priveden to enter priju00edmace (1re,nre) with priju00edmacovu00fdm output napetu00edm (1oreu, noreu) indicating the electrical conductivity contact rolling belt (1rb, 2rb) with wheels (1rw, 2rw, 1nrw, 2nrw) just poju00edu017edenu00e9ho rolling stock section.this involvement is way this indication.they shall be carried out in bezprostrednu00edm area first wheelset (1tw) through the first current cidla (1cd) evaluation of the prutoku first u0161untovu00e9ho current (1isc) and / or in the vicinity of bezprostrednu00edmthe wheelset (ntw) through subsequent flux cidla (ncd) evaluation of the prutoku subsequent u0161untovu00e9ho current (nisc), while the response to u0161untovu00fd current (1isc, nisc) is evaluated in priju00edmaci (1re,nre) as generated by an output electrical signal (1os, nose). if priju00edmaci (1re, nre) priju00edmacovu00e9 output tension (1ore
