Abstract
This invention provides a power-off device for overhead contact lines, comprising a communication circuit for receiving analog signals to be processed, an analog-to-digital converter circuit for converting the analog signals to be processed into digital signals to be processed, a processor for analyzing the digital signals to be processed, and a relay circuit for outputting the analyzed results. The processor is connected to the communication circuit, the analog-to-digital converter circuit, and the relay circuit. This invention ensures that the overhead contact lines can be powered off promptly in the event of a geological disaster, guaranteeing the safety of trains, passengers, and railway facilities. It reduces reliance on manual intervention, improves response speed, avoids the safety hazards associated with manual power-off, and effectively and quickly responds to faults or disasters.
