Abstract: A vehicle control device for a first railroad vehicle includes a case, a first wireless router device housed in the case, and an antenna device. The antenna device is installed on any of outer peripheral surfaces of the case. The first wireless router device transmits collected operation data of the vehicle control device via the antenna device and a first wireless communication network to a second wireless router device arranged in a second railroad vehicle so that a gateway router also arranged in the second railroad vehicle can transmit the collected operation data to an external server via a second wireless communication network.

Abstract: In the railway vehicle power conversion device, an air flow passage is formed by providing an L-shaped partition plate whose long side is in the rail direction, in the interior of a box suspended below the floor of the vehicle. On one side of this partition plate, there are included, in order of the rail direction, a high-speed circuit breaker, relay unit, interface unit and control device. On the other side of partition plate, a pair of smoothing reactors are included on the short side of L-shaped partition plate, and a semiconductor cooling unit is included on the other side of the smoothing reactors and partition. A heat-radiating part of this semiconductor unit projects at the side of air inlet port of air flow passage. Electrically driven fans are fixed within an airflow passage at the smoothing reactors.

Abstract: In the rail way vehicle power conversion device according to the present invention, an airflow passage 6 is formed by providing an L-shaped partition plate (2d) whose long side is in the rail direction, in the interior of a box suspended below the floor of the vehicle. On one side of this partition plate (2d), there are accommodated in order in the rail direction a high-speed circuit breaker (13A), relay unit (13B), interface unit (13C) and control device (13D) . On the other side of partition plate (2d), a pair of smoothing reactors (8A) and (8B) are accommodated on the short side of L-shaped partition plate (2d), and a semiconductor cooling unit (7) is accommodated on the other side of these smoothing reactors (8A), (8B) and partition (2f). A heat-radiating part (7a) of this semiconductor unit (7) projects at the side of air inlet port (2e) of airflow passage (6). Electrically driven fans (9A) and (9B) are fixed within airflow passage (6) at smoothing reactors (8A) and (8B).
