Catenary Fault Location System for Electrified Railway Yard with Soft Suspension
When the catenaries of multi-track station yards of electrified railways encounters short circuit fault,the fault location device at traction substation cannot locate the fault site,which leads to extra-long time cost of finding and remo-ving the fault and even affects the safe and reliable operation of electrified railway.This paper takes the typical catenary of an electrified railway station with soft suspension as the object,and expounds the current distribution of the important nodes of the catenary in the station yard when the fault occurs.On this basis,the voltage and current acquisition units are installed on the important nodes of the catenary of the station yard,and the station yard fault locating analysis platform is configured at the traction substation to locate the fault area and the fault branch of the catenary of the station yard.
