摘　　要：文章结合实际工程应用、铁路电力故障处理现状,在分析铁路供电系统各类型故障特点和故障特征的基础上,针对铁路电力贯通线特点,设计了以铁路专用故障指示器为基础应用于铁路供电系统的故障定位系统。With the rapid development of China’s railway and the transformation of electrification,the power supply lines under the jurisdiction of the railway bureau are vast,and the distribution along the lines is very complex.Among them,the 10 kV power line provides power for traffic lights,office space and even related power supply nearby.Railway transportation is of vital importance to people’s livelihood,so the reliability and stability of operation is of vital importance.The stability and reliability of the corresponding power supply system is also of great importance,that is,the requirements for troubleshooting of power supply system are very high.Once the power supply line breaks down,it will cause the running signal lamp to lose the power supply,unable to work normally,affect the normal running of the locomotive,and even cause a lot of property losses and life safety.Therefore,it is very important for the railway power supply system to inspect the line,find out the fault and quickly remove the fault to restore the normal power supply.
