Definitions

  • a single fuse may comprise a detector, e.g. by its jumping out signaled that the fusible conductor has melted through and so the fuse was triggered. Since the status of a detector is to be visually checked by hand, and because the fuses are sometimes located in hard-to-reach places, for example inside a control cabinet, the monitoring of the individual fuses requires a great deal of effort and therefore takes a relatively long time. especially in larger or more complex plants.
  • the object of the invention is to simplify the automated monitoring of fuses.
  • This object can be achieved by means of a fuse according to claim 1, namely, when the fuse has at least one transponder which is adapted to send a readable signal via radio, and if the fuse is further formed when triggered on the transponder so to prevent it from being able to send a radio-readable signal or to send a modified radio-readable signal. Then it can be seen from the changed or failed signal that the fuse has been triggered. As a result, a very simple monitoring of the fuses without intervention in the main circuit is possible.

Abstract

L'invention concerne un nouveau fusible (100, 200) comprenant au moins un transpondeur (119, 120) conçu pour émettre un signal lisible par voie hertzienne. Ce fusible (100, 200) est conçu pour agir sur le transpondeur (119, 120) en cas de déclenchement de sorte que ledit transpondeur (119, 120) ne puisse plus émettre de signal lisible par voie hertzienne ou puisse émettre un signal lisible par voie hertzienne modifié. Le fusible peut être lu au moyen d'un dispositif d'évaluation (300) conçu pour détecter le déclenchement d'au moins un fusible (100, 200) d'après la perte ou la modification du signal lisible par voie hertzienne émis par le transpondeur (119, 120) du fusible (100, 200) et éventuellement pour informer l'utilisateur et/ou lui fournir des données du fusible (100, 200) déclenché.
