Title:
HIGH-SPEED CIRCUIT BREAKER PROTECTION CONTROL METHOD, CONTROLLER, TRACTION CONTROL SYSTEM AND TRAIN
Document Type and Number:
WIPO Patent Application WO/2019/114651
Kind Code:
A1
Abstract:
A high-speed circuit breaker protection control method, a controller (7), a traction control system (100) and a train (1000). The traction control system (100) comprises a high-speed circuit breaker (1) and an inverter (3) provided respectively corresponding to each carriage of the train (1000), one end of the high-speed circuit breaker (1) being connected to a power source (2), and the other end of the high-speed circuit breaker (1) being connected to the inverter (3). Said protection control method comprises the following steps: acquiring a return detection signal of the high-speed circuit breaker (1), and determining, according to the return detection signal, whether the detection state of the high-speed circuit breaker (1) is in a disconnected state; if it is determined that the detection state of the high-speed circuit breaker (1) is in a disconnected state, acquiring the bus voltage of the inverter (3), and determining, according to the bus voltage, whether the actual state of the high-speed circuit breaker (1) is in a disconnected state; and if it is determined that the actual state of the high-speed circuit breaker (1) is in a disconnected state, generating a first power-off command, and sending the first power-off command to the high-speed circuit breaker (1), such that the high-speed circuit breaker (1) maintains the disconnected state. Thus, the running reliability and safety of the train (1000) are improved.
