Transmittal Signal Frequency of Centre-Fed Ballastless Track Circuit
摘要
Abstract
To determine the frequency range of centre-fed ballastless track circuit, based on the frequency character of the first parameters and the two-port network coefficient expressions of centre-fed ballastless track circuit in normal, shunt and broken-rail operation modes and the different initial values of minimum ballast resistance, surface-conductivity coefficient, input impedance and output impedance, the frequency characters of track circuit broken sensitivity and train shunt sensitivity was simulated by the graphical method. The result shows that the frequency of centre-fed ballastless track circuit is not larger than 700 Hz when the first parameters is the standard parameters of ballastless track circuit.关键词
