Research on the Mechanism of the Capacitive Coupling Interference of Multiline Parallel Track Circuits
There are many many parallel station tracks in high-speed railway stations with complex application sce-narios,and in the case of three parallel lines,the middle station track is susceptible to electromagnetic interference from the two side lines.When the two lines are in the same direction as the middle track,the capacitive coupling interference received by the middle station track is the sum of interference from the two lines,and the larger the coupling capacitance of adjacent lines,the stronger interference.In order to reduce the capacitive coupling interfer-ence among adjacent lines in the case of multiple parallel lines,design measures such as changing the relative layout of lines and adopting shielding can be taken to ensure the stability and reliability of the operation of track circuits in high-speed railway stations.
