The Analysis And Discussion Of Track Circuit Bad Shunting Phenomenon In Wuhan-guangzhou High-speed Railway

With coming of high speed railway era, electricity new technology and new equipment witheach passing day，the role of the track circuit as the main signal equipment mainly include: checkthe train, car passes into the orbit of the road section is free; The rail is complete; Is the carrier ofthe locomotive signal information transmission; It’s the important equipment of signal realizeinterlocking relationship. In the event of bad shunt failure will cause interlock, extremely seriousinfluence on transportation.Since the opening of Wuhan-Guangzhou high-speed railway, Wuhan Electricity ServicesDepartment of Wuhan Railway Administration in the process of track circuit maintenanceanalysis, found the affect driving safety problems of ZPW-2000track circuit: section especiallysplit phase zone section "ride" problems."Ride" problems on site has been found cause codesequence upgrade, route to unlock, leakage into serious consequences, such as road trailermutations as ordinary bullet Wuhan-Guangzhou passenger dedicated to C2way of put intooperation, traffic density increase, Code sequence upgrade may bring more seriousconsequences.This article combined the theoretical analysis and field experiment, according to analyze theformation causes and influence factors of the bad shunting. Take the bad shunting situation ofWuhan Electricity Services Department as an example. From the aspects of technology andmanagement to strengthen the management of bad shunt, reduce the risks causing in track circuitbad shunting, to ensure smooth high-speed rail transport and the safety of people’s lives andproperty.
