Device and method for inductively transmitting electric energy to displaceable consumers

摘要

The invention relates to a device for inductively transmitting electrical energy to displaceable consumers (F1-F13) that can be moved along a track, having a primary conductor arrangement (2) divided into route segments (3-7) that are electrically separated from each other, and extending along the track, wherein individual route segments (3-7) are each associated with at least one current source (3′-7′) for imprinting a continuous current into each of the route segments (3-7), and to a corresponding method. The aim of the invention is to supply the displaceable consumers in an energy-saving manner with electric energy matched to demand, and to allow short reaction times when operating the device. This aim is achieved by providing the device with a means (11) for determining the total power of the displaceable consumers (F1-F13) present in each of the individual route segments (3-7) and with a means (11) for actuating the current sources (3′-7′) for applying the electrical continuous current corresponding to the total power required for each route segment (3-7), or by determining, according to the method, the required total power of the displaceable consumers (F1-F13) present in each route segment and applying an electrical continuous current to each route segment (3-7) by means of the associated current source (3′-7′), said current corresponding to the total power required therein.
