| 摘要 |
The invention relates to a device (1) for feeding a consumer network (13) with electrical power from a supply network (12), wherein the device (1) comprises a frequency converter (2), one side of which can be connected to the supply network (12) and the other side of which can be connected to the consumer network (13), said converter also being able to provide high short circuit currents for the consumer network over a sufficiently long time frame so that a short circuit in the consumer network can be localized and separated in a targeted manner from the remainder of the consumer network, which is fault-free. A mechanical switching unit (3) is disposed parallel to the frequency converter (2) and is adapted to bypass the frequency converter (2), and control means (9) are connected to said switching unit (3), said control means being adapted to actuate the switching unit (2) when a short circuit current flowing across the frequency converter (2) is detected. |
