Abstract
A device for disconnecting a high-voltage direct electric current via a fuse interposed in a main branch, includes an overload system able to generate an oscillating overload current which, in the main branch, over at least one half-period of oscillation, is added to a fault current in terms of absolute value to ensure the melting of the fuse. A method for disconnecting a high-voltage direct electric current, via a fuse interposed in a main branch, includes: storing an electrical energy in an overload system; generating, by the overload system, an oscillating overload current which, in the main branch, over at least one half-period of oscillation, is added to the fault current in terms of absolute value to ensure the melting of the fuse.
