An arrangement comprising a magnetic body (12) having a hole portion (11) for passage of a primary-side first induction line (2), a primary-side second induction line (5) for electrically feeding a load in a contactless manner, an added line (17) passing through the hole portion (11) of the magnetic body, and a first contact (19) for short-circuiting the added line 17. According to this arrangement, short-circuiting provided by the first contact (19) can cut off electric feeding to the primary-side second induction line (5), thereby isolating the load (second-side power receiving circuit) without mechanically switching the power supply line.

La présente invention concerne une installation d'alimentation électrique sans contact comprenant un corps magnétique (12) présentant une partie à trou (11) destinée au passage d'une première ligne d'induction primaire (2), une seconde ligne d'induction primaire (5) servant à fournir une alimentation électrique sans contact à une charge et passant à travers la partie à trou (11) du corps magnétique (12), une ligne supplémentaire (17) passant à travers la partie à trou (11) du corps magnétique (12), et un premier contact (19) servant à court-circuiter la ligne supplémentaire (17). Selon l'invention, l'alimentation électrique fournie à la seconde ligne d'induction primaire (5) peut être interrompue par mise en court-circuit du premier contact (19) et la charge (circuit de réception d'énergie électrique secondaire) peut être déconnectée sans commutation mécanique de la ligne d'alimentation électrique.
