Document Type and Number:
Japanese Patent JP6967162
Kind Code:
B2
Abstract:
In order to reduce the volume and mass of a railroad vehicle drive device as a whole while keeping overhead wiring protected from overcurrent as before, and to reduce overall cost during railroad vehicle production, this railroad vehicle drive device is provided with: a line breaker which cuts off a DC current supplied from DC overhead wiring to a railroad vehicle; a current limiter connected to the line breaker in series; an inverter device comprising a power unit for converting DC power supplied via the current limiter into three-phase AC power, and a filter capacitor; and a filter reactor connected between the current limiter and the filter capacitor. All of the constituent components are contained in the same chassis and integrally mounted on the railroad vehicle. In this way, the filter reactor can be reduced in size, so that, by housing a main circuit from the current limiter to the inverter device in the same chassis and installing and wiring the chassis under the floor of the railroad vehicle, it is possible to complete outfitting for the main circuit system and to significantly reduce the number of wires under the vehicle floor and the number of outfitting man-hours during railroad vehicle production.
