High voltage device for a rail vehicle
View Patent ↗A high voltage device for a vehicle, which at least during driving operation is supplied with electric energy from a power system providing a high voltage, having at least one high voltage component which by a main power switching unit is electrically connectable to the power system and a grounding switching device having at least one switching device. In order to increase personal safety during work on the high voltage device in a constructively simple manner, it is proposed that the high voltage component has at least one receiving region in which the switching device is accommodated—at least in a grounding position that grounds at least one active section of the high voltage component.
1. A high voltage device for a vehicle which at least during driving operation is supplied with electrical energy from a power system providing a high voltage, the high voltage device comprising:
a main power switching unit;
at least one high voltage component, which by means of said main power switching unit can be electrically connected to the power system, and having at least one active section;
said at least one high voltage component being a voltage conversion device which serves, starting from the high voltage provided by the power system, to provide a voltage different therefrom;
a grounding switching device having at least one switch configured to assume a grounding position in which said switch grounds an electrical connection between said active section and said main power switching unit; and
said at least one high voltage component having a housing formed with a receiving region in which said switch is accommodated at least in said grounding position that grounds said at least one active section of said high voltage component, said housing enclosing said at least one active section of said at least one high voltage component.
2. The high voltage device according to claim 1 , wherein said switch is encapsulated in said at least one receiving region.
3. The high voltage device according to claim 1 , wherein said at least one high voltage component is provided for an inductive voltage conversion.
4. The high voltage device according to claim 1 , wherein said at least one high voltage component has at least one cooling and/or insulating material which is provided respectively to cool or electrically insulate said at least one active section, wherein said cooling and/or insulating material serves for electrical insulation of said switch.
5. The high voltage device according to claim 4 , wherein said at least one the receiving region is filled at least partially with said cooling and/or insulating material.
6. The high voltage device according to claim 5 , wherein said cooling and/or insulating material is embodied as a cooling and/or insulating liquid.
7. The high voltage device according to claim 6 , wherein said cooling and/or insulating material is oil.
8. The high voltage device according to claim 1 , wherein said high voltage component is a transformer enclosed in said housing, said transformer including a primary winding forming said active section, a secondary winding and a core.
9. A vehicle, comprising:
a high voltage device which at least during driving operation is supplied with electrical energy from a power system providing a high voltage, said high voltage device containing:
a main power switching unit;
at least one high voltage component, which by means of said main power switching unit can be electrically connected to the power system, and having at least one active section;
said at least one high voltage component being a voltage conversion device which serves, starting from the high voltage provided by the power system, to provide a voltage different therefrom;
a grounding switching device having at least one switch configured to assume a grounding position wherein said switch grounds an electrical connection between said active section and said main power switching unit; and
said at least one high voltage component having a housing formed with a receiving section in which said switch is accommodated in the grounding position that grounds said at least one active section of said high voltage component, said housing enclosing said at least one active section of said at least one high voltage component.
10. The vehicle according to claim 9 , wherein the vehicle is a rail vehicle.
11. The vehicle according to claim 9 , wherein said high voltage component is a transformer enclosed in said housing, said transformer including a primary winding forming said active section, a secondary winding and a core.
