POWER SUPPLY SYSTEM FOR TRAIN TRAVERSING PHASE BREAK, AND TRAIN

WIPO Patent Application WO/2019/109716

A1

A power supply system for a train traversing a phase break, the system comprising: a main circuit breaker (11), a lightning arrester (15), an on-board transformer (12), a first control device (13), and a motor (14). Two ends of the main circuit breaker (11) are connected to a contact network (10) and a primary side of the on-board transformer (12), respectively. One end of the lightning arrester (15) is connected to the ground, and another end thereof is connected to the main circuit breaker (11) and the primary side of the on-board transformer (12). Two ends of the first control device (13) are connected to a secondary side of the on-board transformer (12) and the motor (14), respectively. When the main circuit breaker (11) is closed, the on-board transformer (12) inputs a first voltage to the first control device (13). When the main circuit breaker (11) is open, the motor (14) inputs a second voltage to the on-board transformer (12) via the first control device (13). The first control device (13) adjusts the magnitude of the second voltage to be less than the magnitude of the first voltage. The invention also comprises a train having on-board electrical equipment and the power supply system for a railroad traversal of a phase break.
