AI Technical Summary
In existing technologies, AC electrified railways suffer from speed loss and safety risks when switching between electrical phases, especially under heavy loads or on long gradients, which may lead to train speed loss and accidents. Furthermore, the dual-side power supply method requires manual switching in case of a fault, which poses a safety hazard.
The system adopts an electric phase-splitting and phase-splitting conversion system adapted to bilateral power supply. It utilizes a ground-based automatic phase-splitting device and electronic switch group to automatically achieve energized phase-splitting without the train's awareness when switching from bilateral power supply to single-sided power supply. The power supply arm is switched to provide power to the electric phase-splitting device through the electronic switch group.
It enables trains to automatically energize themselves without being aware of electrical segmentation/phase switching in bilateral power supply mode, avoiding accidents such as phase switching failures and slope stops, thus improving train operation safety and power supply system reliability.
