Abstract

Cette installation (10) d'émission d'une onde électromagnétique à oscillateur commuté comprend : - une ligne (35) de transmission d'une onde électromagnétique jusqu'à une antenne (18) disposée à une première extrémité, ladite ligne de transmission (35) comprenant une âme (43), un blindage (45) entourant l'âme (43) et un matériau diélectrique (46), remplissant l'espace entre l'âme (43) et le blindage (45), et - un éclateur (41), relié à une deuxième extrémité (49) de la ligne de transmission (35), opposée à la première extrémité, l'éclateur comportant deux électrodes reliées respectivement à l'âme (43) et au blindage (45) et entre lesquelles est disposé un liquide diélectrique de commutation. Le liquide diélectrique de commutation a une conductivité inférieure à 10 µS/cm, une rigidité diélectrique supérieure ou égale à 10 kV/mm et un temps de relaxation inférieur à 50 ms.This installation (10) for transmitting a switched oscillator electromagnetic wave comprises: a line (35) for transmitting an electromagnetic wave to an antenna (18) disposed at a first end, said transmission line ( 35) comprising a core (43), a shield (45) surrounding the core (43) and a dielectric material (46), filling the space between the core (43) and the shield (45), and - a spark gap (41), connected to a second end (49) of the transmission line (35), opposite the first end, the spark gap having two electrodes respectively connected to the core (43) and to the shield (45) and between which a dielectric switching liquid is arranged. The switching dielectric liquid has a conductivity of less than 10 μS / cm, a dielectric strength greater than or equal to 10 kV / mm and a relaxation time of less than 50 ms.
