PROCESS FOR MANUFACTURING A FUSE, METHODS OF IMPLEMENTATION AND IDENTIFICATION, AND FUSE

摘要

The present invention relates to a process for manufacturing a fuse, comprising a step of defining the geometry of at least one fusible strip (16) employed in the fuse, in which step the following parameters are considered: a nominal current density (i16) conducted by the fusible strip (16); a nominal operating voltage of the fuse; a Joule integral corresponding, in the pre-arcing regime, to at least one part (18) of the fusible strip; and a Joule integral corresponding, in the arcing regime, to this part (18) of the fusible strip. The process is characterized in that, in this defining step, the Lorentz forces (F21-F25) acting on at least this part (18) of the fusible strip are also taken into consideration. The invention also relates to a fuse, comprising a ceramic casing and at least one fusible strip (16) placed in this casing, characterized in that it also comprises means for controlling the electromagnetic environment of the fusible strip (16) in a pre-arcing and/or a pre-arcing/arcing transition regime by amplifying or attenuating the Lorentz forces acting on at least one part of the fusible strip (16).
