Abstract

Selon l'invention, un appareil de destruction des mauvaises herbes comprend un interrupteur (S), un transformateur (TR), un ensemble cascade (K) de multiplication de tension, et un transformateur haute tension (TRHV) et un ensemble de rétroaction (PS), assemblés ensemble de façon qu'un connecteur d'entrée (F) soit attaché à l'interrupteur (S), un connecteur de sortie duquel est attaché à un connecteur d'entrée du primaire du transformateur (TR), dont l'autre extrémité primaire est connectée à un connecteur d'entrée (N), tandis que les connecteurs de sortie du secondaire du transformateur (TR) sont connectés aux connecteurs d'entrée de l'ensemble cascade (K) dont la sortie est connectée à un connecteur d'entrée du primaire de transformateur haute tension (TRHV), tandis que l'ensemble cascade (K) est connecté par l'intermédiaire de l'ensemble de rétroaction (PS) au deuxième connecteur d'entrée du primaire du transformateur haute tension (TRHV), alors que les connecteurs du secondaire du transformateur haute tension (TRHV) sont connectés aux électrodes (E) qui produisent un fort champ électromagnétique. L'appareil de destruction des mauvaises herbes peut être conçu comme un appareil portable, aussi si les électrodes (E) sont placées sur un support (30) à monter sur des chariots à main, sur un motoculteur, sur un tracteur, sur un camion, sur une remorque ou sur un treuil d'un autre véhicule sur lequel des dispositifs appareils de destruction de mauvaises herbes sont aussi placés, et appareils desquels, par des conducteurs, une haute tension des connecteurs de sortie sur l'appareil est conduite à chacune des électrodes de la pluralité d'électrodes (E) montées sur le support (30). Lors du fonctionnement, l'appareil de destruction des mauvaises herbes expose une plante à un fort champ électrique qui, dans la plante, à cause des pertes, produit de la chaleur de sorte que la température de la plante augmente. L'augmentation de la température dans la plante augmente aussi les pertes diélectriques dans la plante, ce qui engendre une augmentation supplémentaire de la chaleur et une augmentation supplémentaire des pertes. Ce procédé cumulatif continue jusqu'à ce que la chaleur soit telle que la mauvaise herbe est détruite par la pénétration électrothermique.
