Document Type and Number:
WIPO Patent Application WO/2010/049231
Kind Code:
A3
Abstract:
In order to provide a device (1) for feeding a consumer network (13) with the electric power of a supply network (12), wherein the device (1) has a frequency converter (2) which may be connected both to the supply network (12) and to the consumer network (13), by means of said frequency converter high short-circuit currents may also be provided over a sufficiently long time duration for the consumer network such that a short-circuit is localized in the consumer network and may be selectively separated from the remaining, error-free consumer network, the invention provides a switch unit (13), which is disposed parallel to the frequency converter (2) and configured for bypassing the frequency converter (2), and a controller (9) that is connected to the switch unit (3), said switch unit (13) and controller being equipped to actuate a switch unit (2) upon detection of a short-circuit current flowing across the frequency converter (2).
