Analysis on Feeder Protection of Metro Direct Current Traction Power Supply System
In the operation of metro traction power supply system,continuity and reliability are the most basic requirements,and the application of feeder protection technology is a very important means to ensure the normal operation of metro traction power supply system.In the specific implementation of metro direct current traction power supply system feeder protection,the commonly used technology types include high-current tripping protection,timing overcurrent protection,overhead contact line equipment overheating load protection,frame leakage protection,bilateral jump protection,and automatic reclosing technology.These technologies can play a very important role in promoting the feeder protection of metro direct current traction power supply system.However,in the application process,there are certain differences in its mechanism of action.Based on this condition,this chapter elaborates on the above content.
