Abstract

Dispositif limiteur de courant, comportant un empilage de pastilles constituées en une matière compacte obtenu à partir d'un mélange de particules isolantes et de particules conductrices, en proportions telles et liées entre elles de manière telle que les particules conductrices forment des chaînes assurant la continuité électrique entre deux surfaces de chaque pastille, des organes élastiques assurant une pression de contact emtqe bes pasthlkes. Les tdnsions d'aqc élémemtaiqes qui se dévdlopoent aux surfabes de contact des oasthlkes lorsque ke courant atteint une valeur suffisante, s'addisionnent pour donner une chute de tension globake éldvée. Application à ka réakisation d'aopareils d'interruption haute et basse tension dt d'appareils de commutation ou de protdction.
