A Rail line model with distributed parameters of track circuit

Abstract

Models of continuous jointlesstrack circuits with an adaptive receiver are presented, where the power supply is connected to the beginning or middle of the rail circuit, and also to the locomotive receiver. The aim of the work is to develop models of rail lines, which take into account the actual current distribution along the track line and which may be used to research adaptive jointlesstrack circuits. The electric schemes of the jointlesstrack circuits are given, equations, connecting currents and voltages at the ends of the rail line, coefficient of four-pole rail lines, algorithms for calculating track circuits. In conclusion, that the track circuit can operate at an insulation resistance four times lower than the permissible value, where the permissible insulation resistance is Ri = 1om*km. New approaches and tools for analyzing and synthesizing solutions are considered, with considering account real operating conditions and disturbing factors.

Research on fault analysis and health management technology of 25Hz phase-sensitive track circuit

“…Due to the long-term exposure of outdoor equipment to open environments, it is greatly affected by factors such as rain, snow, and traction current interference, which poses great challenges for equipment maintenance personnel. There are three main maintenance measures for track circuits: manual inspection, comprehensive testing vehicles and signal centralized monitoring system [1] .…”
