high breaking capacity fuse, controllable fusing, overcurrent protection
Fuses, usually metal links of a lead alloy, are used extensively around world and work fairly well considering their intrinsic problems. Being dependent on the melting of a metal link, their exact blow point is subject to considerable variation. Therefore, a new type of fuse based on controllable fusing concept is proposed. All the experimental tests outlined that there is the possibility to extend the current protection range both to overloads and shortcircuits. Lower operating times in the case of the new fuse can be obtained for a command in advance through an adequate transducers, depending on di/dt parameter, for instance.
