Energy supply unit for transmitting auxiliary energy to an electrical device
First Claim
1. Energy supply unit (1) for transmitting auxiliary energy for an electrical arrangement, especially for a control circuit (2) in a medium or high voltage facility, whereby the energy supply unit (1) has a primary coil (5), which stands at least indirectly in connection with an energy source (7), a secondary coil (9) which stands at least indirectly in connection with the control circuit (2), and an insulating section installed between the primary coil (5) and the secondary coil (9), over which the transmission of auxiliary energy takes place by means of a magnetic alternating field, characterized in that a primary coil (5) constructed as a flat coil is installed on a first supporting plate (4) and a secondary coil (9) constructed as a flat coil is installed on a second supporting plate (8), the two supporting plates (4, 8) are arranged at a defined distance to each other, and the insulating section is constructed as an air gap (11) formed between the primary coil (5) and the secondary coil (9).

Abstract
An energy supply unit includes a primary coil which is at least indirectly connected to an energy source. In a secondary coil which is at least indirectly connected to the control circuit, and an insulating section formed between the primary coil and the secondary coil. The auxiliary energy is transmitted via the insulating section by way of a magnetic alternating field. The energy supply unit further includes a first carrier plate, a primary coil embodied as a flat coil situated on the first carrier plate, a second carrier plate, and a secondary coil embodied as a flat coil situated on the second carrier plate. The insulating section is embodied as an interferric space formed between the primary coil and the secondary coil.
