Abstract

Cette invention a pour objet de fournir une ligne de transmission d'énergie qui permet des communications et l'alimentation électrique sans contact, qui est exempte du risque de pénétration de saletés ou de poussières, et rayonne un petit nombre d'ondes électromagnétiques. Plus particulièrement, l'invention concerne un système d'alimentation électrique comprenant : une ligne de transmission d'énergie (1) qui comprend un conducteur externe cylindrique (102) ayant une fente s'étendant longitudinalement au sommet et un conducteur interne (101) positionné à l'intérieur du conducteur externe (102) sans toucher le conducteur externe (102), et qui transmet de l'énergie à partir d'une source d'alimentation en CA à une longueur d'onde prescrite ; et un support mobile (600) qui comprend une électrode de réception d'énergie (210) qui fait face sans contact au conducteur interne (101), qui se déplace le long de la ligne de transmission d'énergie (1), et qui reçoit de l'énergie à partir de la ligne de transmission d'énergie (1) par la formation d'une capacité de jonction (Cc1) au moyen du conducteur interne (101) et d'une électrode de réception d'énergie (210), pour alimenter ainsi une charge. Le conducteur interne (110) a une rainure (G) dans laquelle l'électrode de réception d'énergie (210) peut être insérée, et la capacité de jonction (Cc1) est formée dans la rainure (G) entre le conducteur interne (101) et l'électrode de réception d'énergie (210).
