Abstract

A system for transmitting electrical energy from an energy source to a consumer, e.g., for contactlessly transmitting energy to a mobile consumer, includes a first line conductor and a second line conductor. Each line conductor has, in a respective axial direction, an at least approximately rectangular cross-section, the long sides of which are longer than the broad sides. The axial directions of the line conductors extend at a right angle with respect to a vertical direction. The first and second line conductors intersect in an intersection region in which a holding device is arranged, and are arranged outside the holding device such that the long sides of the line conductor cross-sections are parallel to the vertical direction. The first and second line conductors are arranged in a central region of the holding device such that the long sides of the line conductor cross-sections are oriented at a right angle with respect to the vertical direction.

First claim

1 . A system for transmitting electrical energy from an energy source to a consumer, comprising:
a first line conductor; a second line conductor; and a holding device arranged at an intersection region of the first line conductor and the second line conductor; wherein each line conductor has, in a respective axial direction, a rectangular cross-section, long sides of the cross-sections being longer than broad sides of the cross-sections, the axial directions of the line conductors extending at a right angle to a vertical direction; wherein the long sides of the cross-sections arranged outside the intersection region are oriented parallel to the vertical direction; and wherein the long sides of the cross-sections arranged in a central region of the holding device are oriented at a right angle with respect to the vertical direction.

2 . The system according to claim 1 , wherein the system is adapted to contactlessly transmit energy to a mobile consumer.

3 . The system according to claim 1 , wherein the long sides of the cross-sections arranged in a region between an edge region of the holding device and the central region of the holding device are oriented inclined to the vertical direction and inclined to a respective transverse direction.

4 . The system according to claim 1 , wherein the holding device includes an upper part and a lower part arranged offset from one another in the vertical direction, and the line conductors being held between the upper part and the lower part in a form-fitting manner.

5 . The system according to claim 4 , wherein the upper part and the lower part are identical.

6 . The system according to claim 4 , wherein the upper part and the lower part are formed of an electrically insulating material and/or plastic.

7 . The system according to claim 4 , wherein the upper part and the lower part are detachably connected to one another by at least one screw formed of an electrically insulating material and/or plastic.

8 . The system according to claim 1 , wherein the holding device has a circular cross-section with respect to the vertical direction.

9 . The system according to claim 1 , wherein the holding device includes a first channel accommodating the first line conductor and a second channel accommodating the second line conductor, the channels each extending from an edge region of the holding device through the central region of the holding device to a respective opposite edge region of the holding device.

10 . The system according to claim 9 , wherein the first channel extends at a right angle with respect to the second channel.

11 . The system according to claim 9 , wherein the channels have a rectangular cross-section, long sides of the cross-sections of the channels being longer than broad sides of the cross-sections of the channels, in the edge region of the holding device, the long sides of the cross-sections of the channels are oriented parallel to the vertical direction, in the central region of the holding device, the long sides of the cross-sections of the channels are oriented at a right angle with respect to the vertical direction.

12 . The system according to claim 9 , wherein the long sides of the cross-sections of the channels, in a region between the edge region of the holding device and the central region of the holding device, are oriented inclined to the vertical direction and inclined to a respective transverse direction.

13 . The system according to claim 9 , wherein, in the central region of the holding device, the first channel and the second channel extend offset from one another in the vertical direction.

14 . The system according to claim 9 , wherein the holding device includes two first channels accommodating two first line conductors extending in parallel and/or two second channels accommodating two second line conductors extending in parallel.

15 . A system for transmitting electrical energy from an energy source to a consumer, comprising:
a first line conductor; a second line conductor; and a holding device arranged at an intersection region of the first line conductor and the second line conductor; wherein each line conductor has, in a respective axial direction, an at least approximately rectangular cross-section, long sides of the cross-sections being longer than broad sides of the cross-sections, the axial directions of the line conductors extending at a right angle to a first direction; wherein the long sides of the cross-sections arranged outside the intersection region are oriented parallel to the first direction; and wherein the long sides of the cross-sections arranged in a central region of the holding device are oriented at a right angle with respect to the first direction.

16 . A system for transmitting electrical energy from an energy source to a consumer, comprising:
a first line conductor; a second line conductor; and a holding device adapted to be arranged at an intersection region of the first line conductor and the second line conductor; wherein each line conductor has, in a respective axial direction, a rectangular cross-section, long sides of the cross-sections being longer than broad sides of the cross-sections, the axial directions of the line conductors adapted to extend at a right angle to a vertical direction; wherein the long sides of the cross-sections adapted to be arranged outside the intersection region are adapted to be oriented parallel to the vertical direction; and wherein the long sides of the cross-sections adapted to be arranged in a central region of the holding device are adapted to be oriented at a right angle with respect to the vertical direction.
