    • PROBLEM TO BE SOLVED: To provide a DC reactor to be serially connected to the rectifier of a DC transforming station for electric railway which can be prevented from rapid increase of current flowing, at the occurrence of a fault and which can reduce the high-frequency waves generated due to rectification.
      SOLUTION: The DC reactor 1 to be connected to a rectifier 25 of a DC transforming station 20 for electric railway has a coil 2, having a size necessary for suppressing the inductance in the air-core state that can cut off the rise of fault current, at the occurrence of an accident by a circuit breaker, and also has a magnetic core 3 which is to be inserted to the coil so that the inductance in the rated current region of 2,000 A or higher can reduce the rectification ripples generated that accompany rectification.
