Method of manufacture of a fuse, the method of implementing this process, and a fuse relates to means for controlling the environment increasing

摘要

The present invention relates to a method of manufacture of a fuse, comprising a step of determination of the geometry of at least one fusible plate (16) fitted to the fuse, in which it is considered the following parameters: a nominal current of conduction (i16) of the fusible plate (16); a nominal operating voltage of the fuse, a heating corresponding, in a pre - arc, with at least a part (18) of the fuse, and a heating corresponding, in the arc mode, this part (18) of the strip of fusible. The process is characterized in that, in this step of determining, it is also considered the laplace forces (f21 - f25) experienced at least by this part (18) of the strip of fusible. The present invention also relates to a fuse, comprising a ceramic shell and at least one fusible plate (16) located in this case, characterized in that it also comprises means for controlling the electromagnetic environment of the fusible plate (16) in a pre - arc and / or of a transition pre - arc / arc.
