Abstract

Dispositif de protection contre les surtensions, comprenant un limiteur de tension à remplissage de gaz et une varistance à base d'oxyde métallique qui est branchée en parallèle sur ce limiteur de tension. Selon l'invention, la résistance de la ligne 4 est relevée par une résistance ohmique 3, le limiteur de tension 1 à remplissage de gaz est placé du côté de cette résistance où peut se manifester une surtension, tandis que de l'autre côté de cette résistance la varistance 2 limite la tension appliquée au circuit 5 à protéger. Application notamment à la protection des points de couplage à semi-conducteurs dans les installations téléphoniques.
