The Research on track circuit

Abstract With the rapid development of China's railway, the speed of the train has been accelerated step by step, and we have put forward higher requirements for the reliability of the signal system.As an important basic signal equipment of railway, the reliability of ZPW-2000A track circuit is directly related to the safety of train operation.ZPW-2000A track circuit is currently China's most advanced without insulation, of frequency shift track circuit, and the length of transmission, transmission security, reliability, good and easy maintenance, equipment installation standard and index system requirement is very strict. After 2000, track circuit occupies the dominant position of Railway Technology in our country.

In this thesis, the ZPW-2000A track circuit which is widely used in railway system in our country is the main research object. This paper introduces the advantages of ZPW-2000A track circuit and studies the common fault types of track circuit, and puts forward the corresponding solutions to the fault.This thesis analyzes the reason of common red zone and bad shunting,and put forward some countermeasures and solutions to reduce the probability of failure. 

Key Words: track circuit  ZPW-2000A  failure analysis  red zone  bad shunting
