Energy transmission device, cable for this and system of the energy transfer device, the cable and a device to which the means of the power transmission device inductively transmitted electrical current is conductive

摘要

The invention relates to an energy transmission device (1, 1 ') for an inductive transmission of electrical energy, which has at least two primary - side, immediately adjacent, series - connected coils (2) which are substantially congruent to one another and spaced from one another, between two of the immediately adjacent, primary-side coils (2) a housing (3) having a secondary-side coil (4) integrated therein can be arranged, and wherein the distance between two primary-side, immediately adjacent coils (2) is selected such that when generating an alternating magnetic field between the two primary side, immediately adjacent coils (2) or with the aid of the secondary side coil (4) an electric current in the secondary side, between the two primary side coils (2) arranged coil (4) or in the two primary side, immediately adjacent Coils (2) is generated. The present invention also relates to a cable (7) for use in the power transmission device (1, 1 ') and a system of the energy transmission device (1, 1'), the cable (7) and a device (9) to which the means the power transmission device (1, 1 ') inductively transmitted electrical current using the cable (7) is conductive.
