Abstract (en)
[origin: DE19750758A1] The invention relates to a current limiting device for combinational circuits, especially low and medium voltage, for electricity supply systems and power distribution. The current limiting device is formed by a plate conductor element (PE) with a core made out of a substrate material (SK) on which a high temperature supraconductive layer can be deposited and which is terminated on one or both sides by a shunt layer (SS) and surrounded on the outside by a heat insulating surface layer (OS). The current limiting device is fully surrounded by liquid nitrogen (NF) acting as a coolant. Resistive current limitation devices of this kind are used in combinational circuits, especially low or medium voltage, for electricity supply systems and power distribution.
