Reactor for electric railway, power conversion device for electric railway and driving device for electric railway

摘要

PROBLEM TO BE SOLVED: To provide a reactor for an electric railway which, even if a large current is made to flow, obtains a larger inductance and is more unlikely to be saturated in this invention relating to the reactor for the electric railway mounted on a railway vehicle, a power conversion device for the electric railway using this reactor for the electric railway, and a drive device for the electric railway equipped with this power conversion device for the electric railway.SOLUTION: A first magnetic substance 6 is provided in a region located on a solenoid-shaped coil axis 4 and inside the inner diameter of a coil 2, and in a magnetic field distribution 5 on the coil axis 4, a magnetic field during energization is arranged at a position including a region lowered than the central side of the coil 2.
