Abstract

A high-voltage apparatus has at least one high-voltage component and at least one current sensor, which is assigned to a corresponding high-voltage component. The high-voltage apparatus has at least one transmission apparatus, to which at least one corresponding current sensor is assigned. The at least one transmission apparatus is designed to provide an information signal, which contains information on whether there is a potential risk originating from the corresponding high-voltage component or not, depending on a measurement signal of the at least one corresponding current sensor, by way of a wireless radio link in order for the information to be reproduced on an external reproduction apparatus.

Claims

1. A high-voltage apparatus, comprising:

a high-voltage component;

a current sensor associated with the high-voltage component;

a transmission apparatus that includes the current sensor, the transmission apparatus being configured to receive a measurement signal from the current sensor as a basis for providing an information signal via a wireless radio link,

wherein the information signal includes a piece of information on whether or not a potential threat is posed by the high-voltage component, the information signal being utilized by an external reproduction apparatus for conveying the piece of information.

2. The high-voltage apparatus according to claim 1, wherein the information signal contains a piece of position information representative of a position of the current sensor in the high-voltage apparatus.

3. The high-voltage apparatus according to claim 1, wherein the high-voltage apparatus is a vehicle.

4. The high-voltage apparatus according to claim 3, wherein the vehicle comprises a plurality of high-voltage components, each high-voltage component having a respective associated current sensor and transmission apparatus.

5. The high-voltage apparatus according to claim 3, wherein the information signal contains a vehicle identifier representative of a vehicle type of the vehicle.

6. An external reproduction apparatus, comprising:

a radio reception unit configured to receive an information signal provided by a high-voltage apparatus according to claim 1,

wherein the external reproduction apparatus is configured to display a respective two-colored set of traffic lights based on the information signal received associated with the current sensor,

wherein a first traffic light color represents no threat being posed by the high-voltage component and a second traffic light color represents a threat being posed by the high-voltage component.

7. The external reproduction apparatus according to claim 6, wherein

the information signal contains a piece of position information representative of a position of the current sensor in the high-voltage apparatus, and

wherein the external reproduction apparatus is configured to display the respective two-colored set of traffic lights at a position indicative of the position of the current sensor in the high-voltage apparatus.

8. The external reproduction apparatus according to claim 7, wherein

the high-voltage apparatus is a vehicle,

the information signal contains a vehicle identifier representative of a vehicle type of the vehicle,

the external reproduction apparatus is configured to display the respective two-color set of traffic lights at the position indicative of the position of the respective current sensor on a vehicle depiction matching the vehicle type of the vehicle.

9. A system, comprising:
