FIELD: transport engineering; electric vehicles.
SUBSTANCE: proposed system for delivery of current to electric vehicle, particularly, to rail vehicle, contains sequence of conducting segments which are electrically isolated from each other and from conducting rail line in contact with at least one current-collecting shoe of vehicle, and set of high-voltage supply devices. Each device is connected with current conducting segment being provided with means for detecting current-collecting shoe and with switching means for selective supply of corresponding segment when current-collecting shoe is on said segment, and for connecting said current-collecting shoe with zero potential source when current-collecting shoe is not on segment. Switching means consist of pair of members forming static switches controlled by detector to supply current to corresponding segment when current-collecting shoe is on said segment, and to connect it with zero potential source when current collecting shoe is not on segment, respectively. Each supply device includes short-circuiting means shifted into closed state which is arranged between corresponding segment and zero potential source and which is to be opened by detector.
EFFECT: provision of current supply through ground by device easy to operate.
