Abstract:
A self-recovering current-limiting device, the device comprising:a first and a second electrode for connection to an electric circuit to be protected, each of the first and second electrodes being made of a respective solid metal; a respective non-conductive ceramic disk disposed at a respective inner surface of each of the first and second electrodes; a plurality of pressure-resistant insulating bodies; and a plurality of insulating intermediate walls supported by the plurality of insulating bodies; wherein the plurality of insulating intermediate walls and the plurality of pressure-resistant insulating bodies define a plurality of compression spaces, the plurality of compression spaces being disposed one behind the other between the first and second electrodes and being at least partially filled with a liquid metal; and wherein the plurality of insulating intermediate walls define a plurality of connecting channels therein, each of the respective non-conductive ceramic disks being disposed opposite of the respective connecting channel of a respective adjacent one of the plurality of insulating intermediate walls.
