Abstract

L'invention concerne un dispositif formant parafoudre. Selon l'invention, il comprend un boîtier cylindrique à la masse 12a ayant une surface latérale interne, un conducteur 10a supporte en relation électriquement isolante par rapport au boîtier, un certain nombre de résistances non linéaires 26 disposées dans le boîtier, pour être interconnectées en série à travers le conducteur électrique et la surface latérale interne du boîtier, et un moyen 28 pour étendre le conducteur électrique d'une extrémité des résistances non linéaires qui est placée à une haute tension pour disposer une partie étendue de ce conducteur électrique près des résistances non linéaires interconnectées en série. L'invention s'applique notamment aux parafoudres pour sous-stations miniatures.
