Abstract

Dispositif de protection à effet de champ contre les surtensions. On obtient le processus d'amorçage de la décharge grâce à un jeu de deux électrodes secondaires, en parallèle avec les électrodes primaires, de façon à créer des couples ioniques grâce à des électrons émis par l'effet de champ; les électrodes sont toutes enfermées dans une enceinte contenant un gaz, et les électrodes secondaires créent un champ électrique plus intense que celui présent entre les électrodes primaires. Application aux installations de radar, aux lignes de télécommunications, de signalisation à distance, etc.Field-effect surge protection device. The discharge initiation process is obtained by means of a set of two secondary electrodes, in parallel with the primary electrodes, so as to create ionic couples thanks to the electrons emitted by the field effect; the electrodes are all enclosed in an enclosure containing a gas, and the secondary electrodes create an electric field more intense than that present between the primary electrodes. Application to radar installations, telecommunications lines, remote signaling, etc.
