Description

Arrangement in particular for a car body of a track-guided vehicle The invention relates to an arrangement, in particular for a car body of a track-guided vehicle, comprising a high-voltage assembly and at least one cladding assembly, wherein the high-voltage assembly has at least one live component. Furthermore, the invention relates to a car body, in particular for a track-guided passenger transport vehicle, comprising at least such an arrangement or, as described below, a further developed arrangement. Furthermore, the invention relates to a track-guided vehicle, preferably rail vehicle, comprising at least such an arrangement or, as described below, a further developed arrangement and / or at least such a car body or, as described below, a further developed car body. EN 50122-1 places requirements on the electrical clearance which must be maintained between touchable live parts of a rail vehicle and persons located on the platform, for instance. This problem previously did not exist in this form, or the existing permissible installation space was sufficient. Before 2022, the electrical clearance according to EN 50122-1 could be provided with a straight object with a length of 3500mm. In the new version, the stick figure method was introduced, according to which a person manually holding a rod with a length of 500mm and the points in the room that can be reached by it defines the respective electrical clearance. On that basis, the object underlying the invention is to create an arrangement, in particular for a car body of a track-guided vehicle, which prevents the flashover of voltage with a reduced installation space. This object is achieved by the arrangement of claim 1. Furthermore, the object is achieved by the car body of claim 9. Furthermore, the object is achieved by the track-guided vehicle of claim 14. Advantageous embodiments and developments are the subject matter of the respective subclaims. In accordance with the invention, an arrangement, in particular for a car body of a track-guided vehicle, is provided, comprising a high-voltage assembly and at least one cladding assembly, wherein the high-voltage assembly has at least one live component. The cladding assembly has at least one grounded barrier, which is spaced apart from the high- voltage assembly by an air gap. Furthermore, in accordance with the invention a car, in particular for a track-guided passenger transport vehicle, is provided, comprising such an arrangement, or as described below, a further developed arrangement, wherein the car body has a roof and at least one side wall. Furthermore, provision is made, in accordance with the invention, for a track-guided vehicle, preferably rail vehicle, comprising at least such an arrangement, or as described below, a further developed arrangement and / or at least such a car body, or as described below, a further developed car body. The track-guided vehicle is, for example, a rail vehicle or a maglev train, preferably for passenger transport. Passenger transport vehicles are embodied in such a way that a plurality of people can remain in the interior of the vehicle and it is specially adapted to the requirements of passenger transport. The solution according to the invention makes it possible to reduce the distance required in EN 50122-1. This means that only the electrical distance according to EN 50124 Part 1 (air gap) must be maintained. The procedure described enables compliance with EN 50122-1 and makes a significantly larger installation space available for the devices. The grounded barrier is embodied in such a way that a straight line is not possible between the end of the object and the live component, and a barrier blocks the way. The grounded barrier ensures that an E-field of the live part of the high- voltage assembly terminates at it. The electric field is formed here between the high-voltage assembly and the grounded barrier and preferably not beyond that. In an advantageous development of the arrangement, provision can be made for the barrier of the cladding assembly to have a base and an extension area, wherein the extension area extends away from the base, and a distal end of the extension area is preferably arranged closer to the live component than the base. This makes it possible to reduce the distance between the high-voltage assembly and the grounded barrier to a minimum and at the same time to leave as much installation space as possible for other assemblies and in particular the high- voltage assembly. In an advantageous development of the assembly, provision can be made for the air gap to be embodied between the distal end of the extension area and the live component. This specifies an air gap that indicates a defined distance between the high-voltage assembly and the grounded barrier. In an advantageous development of the arrangement, provision can be made for the voltage of the live component to be 25kV AC and for the air gap L to be at least 300mm, preferably at least 230mm; or for the voltage of the live component to be 15kV AC and for the air gap to be at least 200mm, preferably at least 150mm; or for the voltage of the live component to be 3kV DC and for the air gap to be at least 100mm, preferably at least 80mm; or for the voltage of the live component to be 1.0kV AC or 1.5kV DC and for the air gap to be at least 100mm, preferably at least 80mm. The solution according to the invention makes it possible to reduce the distance required in EN 50122-1, e.g. with 25kV from 600 mm to 230 mm. This means that only the electrical distance according to EN 50124 Part 1 (air gap) of 230 mm must be maintained. In an advantageous development of the assembly, provision can be made for the grounded barrier to be embodied to be 2- dimensional. This provides a 2-dimensional shielding of the high-voltage structure. In an advantageous development of the arrangement, provision can be made for the grounded barrier to be embodied such that an electric low-exposure area is embodied on a side of the cladding assembly, grounded barrier, which faces away from the high-voltage assembly. In the area behind the grounded barrier, in the area of the blue object, there is only a very low field density in which an arc can no longer be created. This can therefore also penetrate far into the electrical clearance (table 2 of EN 50122-1) without being exposed to risk. In an advantageous development of the arrangement, provision can be made for an insulating layer to be arranged on the side of the cladding assembly which faces away from the high- voltage assembly. This provides enhanced protection. In an advantageous development of the arrangement, provision can be made for the cladding assembly to have an additional, preferably non-conducting exterior cladding element on the side of the cladding assembly facing away from the high- voltage assembly. This provides enhanced protection. Furthermore, the additional, preferably non-conducting exterior cladding element can be freely designed. In an advantageous development of the car body, provision can be made for the at least one live component to be arranged in an exposed and touchable manner on the roof of the car body. In an advantageous development of the car body, provision can be made for the cladding assembly to be connected directly with the roof of the car body such that an electrically conducting connection is formed between the extension area, preferably between the distal end of the extension area and the car body, in order to ground the grounded barrier. This provides an optimal rating for the car body. In an advantageous development of the car body, provision can be made for the at least one cladding assembly to be arranged in a transition area between the roof and side wall. This makes it possible for the side wall to be extended upward by way of the cladding assembly. In an advantageous development of the car body, provision can be made for the grounded barrier to extend the side wall in such a way that an object approaching the grounded barrier from the side and from below cannot penetrate the air gap. This ensures that an object approaching the barrier cannot be reached by an arc formed by the high-voltage assembly. All embodiments of the arrangement and / or car body apply in the same way to the track-guided vehicle and vice versa. The invention is to be explained below on the basis of an exemplary embodiment with respect to the drawing.

The at least one live component 110 is arranged in an exposed and touchable manner on the roof 4 of the car body 2. The cladding assembly 200 is directly connected to the roof 4 of the car body 2 such that an electrically conducting connection is formed between the extension area 230, preferably between the distal end 232 of the extension area 230 and the car body 2, in order to ground the grounded barrier 210.
