| 摘要 |
The invention relates to a system (20) for supplying auxiliary drives (18) in a rail vehicle with electrical power, wherein said system (20) is connected via an isolating transformer (14) to a power source, such as a DC voltage intermediate circuit (7), wherein said system (20) is connected without a resistor, which limits the current flow, interposed via a protective switch (25) to an electrical reference potential, in particular to vehicle ground, and wherein said protective switch (25) is designed to open upon passage of a current flow through said closed protective switch (25), which is caused by an additional contact of said system (20) to said reference potential. |
