| Summary: | The ground automatic neutral section passing device has been widely used in high-slope and heavy-duty electrified railways. In order to prevent catenary breakdown caused by locomotives, fully guarantee the safe operation of locomotives and traction power supply system, ensure line transportation capacity and minimize the fault range and recovery time of the ground automatic neutral section passing device, by means of the comparative study of various protection schemes, a kind of three-dimensional protection scheme was designed, which took the active controllable electronic tag as the core and also had automatic power-off label and signal lights. The protection logic was discussed and the engineering application design was carried out. Through the on-site joint simulation test, the electronic tag with encryption matching technology could realize the safety and control of the protection area while the power-off label and the signal lights could effectively warn the drivers to check and confirm. |
