Abstract

The entry transition couples an electromagnetic source to the test cell, and delivers either an electromagnetic impulse with a rapid rise time (less than 500 pico-second) and an amplitude of 100 kV, or continuous high tension electromagnetic waves. The entry has a tapered metal envelope (1) with a fixing and adaptation plate (6), to connect to the test cell, at its larger end. A divergent plate (4) inside the envelope fixes to the septum of the test cell. A moulded resin lining (3) prevents arcing. A male connector (2) at the narrow end provides connection to the source of high tension electromagnetic waves.

Description

La présente invention se rapporte aux cellules de test électromagnétique. Plus particulièrement, I'invention concerne les transitions d'entrée des cellules dites de type Giga Transverse
ElectroMagnétique.The present invention relates to electromagnetic test cells. More particularly, the invention relates to the input transitions of cells called Giga Transverse type
Electromagnetic.

De façon connue la connection entre les cellules de test et les systèmes de mesures extérieurs se fait par une transition d'entrée permettant d'adapter la structure coaxiale en provenance des systèmes de mesures extérieurs, à la structure géométrique de la cellule de test. In known manner, the connection between the test cells and the external measurement systems is made by an input transition making it possible to adapt the coaxial structure coming from the external measurement systems, to the geometric structure of the test cell.

Différentes transitions existent à ce jour permettant, soit d'aborder un contexte fréquentiel élevé en mode onde entretenue, soit un contexte de tension élevée en mode impulsionnel. En revanche, aucune transition permet d'aborder, jusqu'à ce jour, les deux contextes simultanément. Various transitions exist to date allowing, either to approach a high frequency context in continuous wave mode, or a context of high voltage in pulse mode. On the other hand, no transition makes it possible to approach, to date, the two contexts simultaneously.

Cet inconvénient limite sérieusement les applications des cellules dans les domaines de Très Haute Tension en mode impulsionnel ( avec des temps de montée inférieur à une nanoseconde).  This drawback seriously limits the applications of cells in the fields of Very High Voltage in impulse mode (with rise times of less than one nanosecond).

La présente invention a pour but de pallier à ces inconvénients. L'objectif de l'invention est de permettre ces applications mais non exclusivement applicable au milieu impulsionnel. The present invention aims to overcome these drawbacks. The objective of the invention is to allow these applications but not exclusively applicable to the pulse medium.

Cet objectif, ainsi que d'autres qui apparaîtront par la suite est atteint par un système qui comprend une transition d'entrée (1) amovible vis-à-vis de l'interface d'accès à la cellule, assurant la connection requise en continuité électrique du septum de celle-ci et une connectique coaxiale (2) mâle au standard Très Haute Tension (THT 100 kV), d'impédance caractéristique Zc = 50 Ohms, spécifiquement développée. This objective, as well as others which will appear subsequently, is achieved by a system which includes a removable input transition (1) vis-à-vis the access interface to the cell, ensuring the required connection in electrical continuity of the septum thereof and a male coaxial connection (2) to the Very High Voltage standard (THT 100 kV), with characteristic impedance Zc = 50 Ohms, specifically developed.

Ce dispositif de transition d'entrée (1) de cellule de test électromagnétique assure, soit la transmission d'ondes électromagnétiques délivrées en régime impulsionnel avec un temps de montée rapide inférieur à 500 pico-secondes et une amplitude de
Très Haute Tension 100 kV, soit la transmission d'ondes électromagnétiques délivrées à forte puissance en régime entretenu.This input transition device (1) for an electromagnetic test cell ensures either the transmission of electromagnetic waves delivered in pulse mode with a rapid rise time of less than 500 pico-seconds and an amplitude of
Very High Voltage 100 kV, i.e. the transmission of electromagnetic waves delivered at high power under sustained conditions.

I1 est caractérisé en ce qu'il comporte en enveloppe métallique (1) présentant une platine de fixation et d'adaptation (6) sur une cellule de test, et pourvu d'une âme (4) qui se fixe au septum de la cellule de test, d'un isolant en résine moulée (3) évitant le claquage en Très
Haute Tension, et d'une connectique mâle (2) permettant le passage de la Très Haute Tension. I1 is characterized in that it comprises a metal casing (1) having a fixing and adaptation plate (6) on a test cell, and provided with a core (4) which is fixed to the septum of the cell test, of a molded resin insulator (3) avoiding breakdown in Very
High Voltage, and a male connector (2) allowing the passage of Very High Voltage.
