Document Type and Number:
WIPO Patent Application WO/2024/060406
Kind Code:
A1
Abstract:
An urban rail vehicle power supply control device, comprising a first power source (201), two sockets (1) for sheds provided in a high voltage box of an urban rail vehicle, and in-shed plugs (3) provided in a shed. A first contact pair is provided between each socket (1) for sheds and each in-shed plug (3); the first contact pair comprises a first plug electric contact (31) and a second plug electric contact (32) provided on the in-shed plug (3), and a first socket electric contact (11) and a second socket electric contact (12) provided on the socket (1) for sheds. Two first socket electric contacts (11) corresponding to the two sockets (1) for sheds are electrically connected to each other, and two second socket electric contacts (12) corresponding to the two sockets (1) for sheds are electrically connected to each other. Socket cover plates (2) are provided with conductive blocks (21). The urban rail vehicle is further provided with a switch unit which is in a closed state only when a first condition is satisfied, wherein the first condition is that all knife switches on the urban rail vehicle are located at a power supply position for sheds; the switch unit is electrically connected between the two first socket electric contacts (11) corresponding to the two sockets (1) for sheds of the high voltage box, or is electrically connected between the two second socket electric contacts (12) corresponding to the two sockets (1) for sheds of the high voltage box. Further provided is an in-shed power supply control device for urban rail vehicles.
