Assembly for Electrically Protecting a Potential Short-Circuit or an Overload in a Direct Current Power Network Having a System-Determined, Variable Source-Internal Resistance

摘要

One assembling is used to electrically protect a potential short circuit path in the power network with an energy stores and there is a system to determine, resistance in variable source. Assembling includes a separator; its trigger characteristic is insufficiently suitable for protection in energy stores; and first and second conductor section of the potential short circuit path in the first mode of operation of second protective device; it is configured to protect first and second conductor section from a load, and the triggering limit of the separator in the first mode of operation appear below.
