HIGH VOLTAGE DEVICE SYSTEM OF A RAILCAR, AND RAILCAR

摘要

A high voltage device system (100) of a railcar according to the present invention is a high voltage device system mounted on a railcar (10) and includes a plurality of high voltage devices (30, 40) to which high-voltage electric power from an overhead contact line is supplied, a plurality of high-voltage cables (70) configured to connect the high voltage devices (30, 40) with each other, and a joint device (51) to which the high-voltage cables (70) are connected. The high-voltage cables (70) respectively include cable connector portions (72) at tip end portions thereof, and each of the cable connector portions (72) includes a base tubular portion (78) configured to cover the high-voltage cable (70) and a fit tubular portion (77) extending from the base tubular portion (78) in a direction substantially perpendicular to a longitudinal direction of the high-voltage cable (70). The joint device (51) includes joint connector portions (55), each of which is fitted to the fit tubular portion (77) of the cable connector portion (72) to be connected to the high-voltage cable (70).
