TRACTION NETWORK AND METHOD FOR OPERATING A TRACTION NETWORK OF AN ELECTRICALLY-DRIVEN TRANSPORTATION VEHICLE IN THE EVENT OF A SHORT CIRCUIT

摘要

A method for operating a traction power supply system of an electrically-driven transportation vehicle in response to a short circuit, wherein the traction power supply system includes a voltage source and at least two electric drive units connected to the voltage source via respective electrical distribution paths, and wherein at least one electrical isolating element for selective isolation of the voltage source is arranged in the distribution path of each drive unit, wherein, in response to a short circuit in the traction power supply system being detected, the method includes detecting in which distribution path and/or in which drive unit the short circuit is present; operating the traction power supply system in a ready-to-drive state, wherein only that drive unit in which or in the distribution path of which the short circuit is present is isolated from the voltage source.
