CIRCUIT BREAKER CONTROLLER FOR ELECTRICALLY POWERED TRAIN

To provide a circuit breaker controller for an electric train that can perform circuit interruption reliably before proceeding into a dead section, while preventing a train from stopping due to circuit interruption at a time of passing through the dead section. A circuit breaker controller 100 is mounted on each vehicle of an electric train together with a receiver 13 that detects a track antenna beacon installed at a predetermined position before and after the dead section, to control a circuit breaker 10 provided between a power collector and a main circuit device by detecting the track antenna beacon by the receiver 13. The circuit breaker controller 100 includes a running-position calculation unit 21 that calculates a running position of the vehicle based on a speed of the electric train, a circuit-breaker control-position calculation unit 22 that calculates a circuit-breaker off-control position at which the circuit breaker 10 is off-controlled according to a speed of the electric train at a point in time at which the receiver 13 detects the track antenna beacon installed before the dead section in the traveling direction, and a circuit breaker control unit 23 that executes off-control of the circuit breaker 10 at a point in time at which the running position and the circuit-breaker off-control position match each other.
