The invention relates to a high-voltage apparatus. Furthermore, the invention relates to a corresponding external reproduction apparatus. Furthermore, the invention relates to a corresponding system having the high-voltage apparatus and the external reproduction apparatus.
If an accident occurs in or with a high-voltage apparatus, it is often impossible for people outside the high-voltage apparatus to tell whether the high-voltage apparatus is live and whether a threat is therefore posed by the high-voltage apparatus.
The object on which the invention is based is that of providing a high-voltage apparatus and an external reproduction apparatus that helps to make it possible to ascertain without touching whether a threat is posed by the high-voltage apparatus.
This and other objects are achieved by a high-voltage apparatus having at least one high-voltage component, at least one current sensor that is associated with a respective high-voltage component, and at least one transmission apparatus that has at least one respective associated current sensor, wherein the at least one transmission apparatus is designed to take a measurement signal from the at least one respective current sensor as a basis for providing an information signal via a wireless radio link, which information signal has a piece of information about whether or not a potential threat is posed by the respective high-voltage component, for the purpose of reproducing the piece of information on an external reproduction apparatus.
The invention is distinguished by a high-voltage apparatus. The invention is furthermore distinguished by a corresponding external reproduction apparatus. The invention is furthermore distinguished by a system having the high-voltage apparatus and the external reproduction apparatus.
The high-voltage apparatus has at least one high-voltage component. The high-voltage apparatus has at least one current sensor that is associated with a respective high-voltage component. The high-voltage apparatus has at least one transmission apparatus that has at least one respective associated current sensor. The at least one transmission apparatus is designed to take a measurement signal from the at least one respective current sensor as a basis for providing an information signal by way of a wireless radio link. The information signal has a piece of information about whether or not a potential threat is posed by the respective high-voltage component. The at least one transmission apparatus is designed to provide the information signal by way of a wireless radio link.
By way of example, for each current sensor, the high-voltage apparatus has a transmission apparatus that has only one respective associated current sensor.
Examples of such high-voltage components are components that are provided for producing, transmitting and/or consuming electric power at a high electrical voltage. A high electrical voltage of this kind is at least 300 V for example. A high-voltage component of this kind is an electrical energy store, an electric drive machine, a cable, a plug and/or a connection in the high-voltage apparatus, for example.
The current sensor is installed in a manner integrated in a plug and/or in what is known as a black box and/or in a cable, for example.
An example of a high-voltage apparatus of this kind is a vehicle, such as a hybrid or electric vehicle, a test bench, a photovoltaic installation, a power supply installation, a rail vehicle installation and/or a rail vehicle.
A high-voltage apparatus of this kind allows the information signal to be provided for the external reproduction apparatus, which information signal has a piece of information about whether or not a potential threat is posed by the respective high-voltage component. By way of example, the information includes whether or not the respective at least one current sensor measures an electric current and/or what the level of the measured electric current is and/or whether the respective at least one current sensor has a fault. This means that it is possible for an emergency worker, for example, to establish whether a threat is posed by the high-voltage apparatus and whether or not he or she can approach the high-voltage apparatus without danger in a simple manner and without touching.
According to a further advantageous embodiment, the information signal has a piece of position information that is representative of a position of the at least one respective current sensor in the high-voltage apparatus.
This means that it is a very simple matter for the emergency worker, for example, to establish where the respective current sensor is positioned in the high-voltage apparatus. It is therefore possible to establish what location in the high-voltage apparatus may pose a threat.
According to a further advantageous embodiment, the high-voltage apparatus is a vehicle.
Specifically in the case of a vehicle, such as a hybrid vehicle and/or an electric vehicle, it is important for the emergency worker to know whether or not he or she can approach the vehicle in order to be able to initiate rescue measures quickly and safely.
According to a further advantageous embodiment, the information signal has a vehicle identifier that is representative of the vehicle type of the vehicle.
Specifically in the case of modern vehicles, it is often not immediately evident from the outside whether an electric vehicle and/or a hybrid vehicle is involved. Transmission of the vehicle type allows the rescue worker, for example, to tell whether the vehicle is an electric vehicle and/or a hybrid vehicle.
The external reproduction apparatus has a radio reception unit that is designed to receive the information signal that has been provided by the high-voltage apparatus or by an advantageous embodiment of the high-voltage apparatus. The external reproduction apparatus is designed to react to reception of the information signal by displaying a respective two-colored set of traffic lights that is associated with the at least one respective current sensor. A first traffic light color is representative of no threat being posed by the respective high-voltage component. A second traffic light color is representative of a threat being posed by the respective high-voltage component.
The external reproduction apparatus has a display, for example, such as a screen, for reproduction. The external reproduction apparatus is particularly a portable apparatus, such as a smart phone and/or a tablet PC.
The respective two-colored set of traffic lights provides a simple way of using the external reproduction apparatus to reproduce whether or not the respective high-voltage component poses a threat. By way of example, the first traffic light color may thus be green and the second traffic light color may be red.
According to one advantageous embodiment, the information signal has a piece of position information that is representative of a position of the at least one respective current sensor in the high-voltage apparatus. The external reproduction apparatus is designed to display the respective two-colored set of traffic lights at the position of the at least one respective current sensor.
This means that the position of the at least one respective current sensor can be displayed on the external reproduction apparatus in a simple manner. By way of example, it is thus a simple matter for the rescue worker to establish where the respective current sensor is positioned in the high-voltage apparatus. Hence, it is possible to establish what location in the high-voltage apparatus may pose a threat.
According to a further advantageous embodiment, the high-voltage apparatus is a vehicle. The information signal has a vehicle identifier that is representative of a vehicle type of the vehicle. The external reproduction apparatus is designed to display the respective two-colored set of traffic lights at the position of the at least one respective current sensor on a vehicle depiction that matches the vehicle type of the vehicle.
This means that the external reproduction apparatus can be used to display simply and clearly where the respective at least one current sensor and the respective high-voltage component are arranged in the vehicle.
