の保護動作が容易になる。F0 action If configured as described above, if a ground fault occurs on the side of the electric train line in a double-track configuration, the fault current can be immediately interrupted by interrupting one set of circuit breakers, making it possible to immediately interrupt the fault current. It becomes easier to take. In addition, since a diode is inserted between the power running bus and the roundworm bus, the fault current from the forward power converter that flows into the reverse power converter side when commutation of the reverse power converter fails is interrupted by a circuit breaker. This makes it possible to prevent the spread of accidents involving reverse power converters. Furthermore, a diode is also connected between the commonly connected anode sides of the bidirectional power converter and the diode bridge circuit, so even if a ground fault occurs while the bidirectional power converter is in forward power conversion operation, power will not continue. Since the current is blocked by the diode and the powering current passes through the circuit breaker, protective operation in the event of an accident becomes easy.
