Title:
TRACK CIRCUIT PROTECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/063337
Kind Code:
A1
Abstract:
A track circuit protection system, comprising a choke transformer (BE), a hollow coil (SVA), tuning matching units (PT) and a compensation tuning unit (TB), wherein the choke transformer (BE) comprises a choke coil and two leading-out terminals (1, 2); the choke transformer respectively realizes connection with two tracks by means of the two leading-out terminals (1, 2); the hollow coil (SVA) comprises a choke coil and two leading-out terminals; the hollow coil (SVA) respectively realizes connection with the two tracks by means of the two leading-out terminals; the tuning matching units (PT) are connected at two ends of the hollow coil (SVA); and the compensation tuning unit (TB) comprises an oscillation branch and a capacitance branch connected in parallel, and the compensation tuning unit (TB) is connected between the two tracks. The track circuit protection system can effectively eliminate the amount of crosstalk disturbance of adjacent segments after a damage fault of a mechanical insulation section occurs and can substantively reduce the impact of high-frequency components in a traction current on the monitoring of a track circuit, thereby ensuring the operating safety of a railway system.
