CONNECTOR STRUCTURE OF MAIN TRANSFORMER AND HIGH-VOLTAGE DEVICE BOX, AND RAILWAY VEHICLE INCLUDING SAME

PROBLEM TO BE SOLVED: To improve electric connection workability of the main transformer and the high-voltage device box of a railway vehicle, followability to the relative position changes of the main transformer and the high-voltage device box, and freedom of underfloor device laying-out.SOLUTION: A connection structure includes a circuit breaker connected to a power cable for supplying high-voltage power, a high-voltage device box housing the circuit breaker and installed in a vehicle underfloor, a main transformer transforming the voltage of the high-voltage power and installed in the vehicle underfloor, a first connector device electrically connected to the circuit breaker and installed in the partition wall of the high-voltage device box, a second connector device electrically connected to the main transformer and installed in the partition wall of the main transformer, and a high-voltage cable having a cable connector part loaded at both ends and covered to be insulated. The cable connector part is fitted and connected to the first connector device and the second connector device, and thus the first connector and the second connector device are connected by the high-voltage cable.
