| Abstract [eng] |
Audio frequency track circuit is a new generation electronic schematics to control occupation of a rail sector. The signalling currents used in these circuits are at 12 or 8 Hz manipulated 420, 480, 580, 720 or 780 Hz frequency currents. It is a higher frequency of current related to ordinary track circuits, so before calculation the influence of current frequency on track line parameters must be investigated. A new model of branchy track line parameter calculation model was suggested, the results of the mathematical experiment were presented. It was shown that there are critical lengths of separate branches that make inauspicious circumstances for normal mode functionality. Results show that there are certain circumstances at which track circuit can not be tuned correctly. |
