[0002] Arrangement in particular for a car body of a track-guided vehicle

[0003] 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 voltage-carrying component.

[0004] Furthermore, the invention relates to a car body, in particular for a track-guided vehicle for passenger transport, comprising at least one such arrangement or one further developed as described below.

[0005] Furthermore, the invention relates to a track-guided vehicle, preferably a rail vehicle, comprising at least such an arrangement or an arrangement further developed as described below and / or at least one car body such or a car body further developed as described below.

[0006] EN 50122-1 specifies requirements for the protective distance that must be maintained between accessible live parts of a railway vehicle and persons, for example, on the platform. This problem did not exist previously in this form, or rather, the existing permissible installation space was sufficient. The protective distance specified in EN 50122-1 before 2022 could be achieved using a straight object 3500 mm long. The new version introduces the stick figure method, according to which a person holding a 500 mm long rod and the points in space that can be reached with it defines the respective protective distance.

[0007] Based on this, the object of the invention is to create an arrangement, in particular for a car body of a track-guided vehicle, which avoids the flashover of electrical voltage while reducing installation space.

[0008] 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 further developments are the subject of the respective subclaims.

[0009] According to the invention, an arrangement is provided, in particular for a car body of a rail-guided vehicle, 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 arranged spaced from the high-voltage assembly by an air gap.

[0010] Furthermore, according to the invention, a car body is provided, in particular for a rail-guided vehicle for passenger transport, comprising such an arrangement or an arrangement further developed as described below, wherein the car body has a roof and at least one side wall.

[0011] Furthermore, according to the invention, a track-guided vehicle, preferably a rail vehicle, comprising at least such an arrangement or an arrangement further developed as described below and / or at least one car body such or a car body further developed as described below is provided.

[0012] The track-guided vehicle is, for example, a rail vehicle or a magnetic levitation train, preferably for passenger transport.

[0013] Passenger transport vehicles are designed in such a way that a number of people can be accommodated in the interior of the vehicle and are specifically adapted to the requirements of passenger transport.

[0014] The inventive solution makes it possible to reduce the distance required by EN 50122-1. Thus, only the electrical distance according to EN 50124 Part 1 (clearance) needs to be maintained.

[0015] The described procedure enables compliance with EN 50122-1 and provides significantly more installation space for the devices. The grounded barrier is designed so that a straight line is not possible between the end of the object and the live component; a barrier blocks the path. The grounded barrier ensures that an electric field from the live part of the high-voltage assembly ends at this point. The electric field forms between the high-voltage assembly and the grounded barrier, and preferably not beyond it.

[0016] In an advantageous development of the arrangement, it can be provided that the barrier of the cladding assembly has a base and an extension region, wherein the extension region extends away from the base, and preferably a distal end of the extension region is arranged closer to the voltage-carrying component than the base.

[0017] This makes it possible to reduce the distance between the high-voltage module and the grounded barrier to a minimum while leaving as much space as possible for other modules, and in particular the high-voltage module.

[0018] In an advantageous further development of the arrangement, it can be provided that the air gap is formed between the distal end of the extension region and the voltage-carrying component.

[0019] This specifies an air gap that indicates a defined distance between the high-voltage assembly and the grounded barrier.

[0020] In an advantageous development of the arrangement, it can be provided that the electrical voltage of the live component is 25 kV AC and the air gap L is at least 300 mm, preferably at least 230 mm; or the electrical voltage of the live component is 15 kV AC and the air gap is at least 200 mm, preferably at least 150 mm; or the electrical voltage of the live component is 3 kV DC and the air gap is at least 100 mm, preferably at least 80 mm; or the electrical voltage of the live component is 1.0 kV AC or 1.5 kV DC and the air gap is at least 100 mm, preferably at least 80 mm.

[0021] The inventive solution makes it possible to reduce the distance required by EN 50122-1, for example, from 600 mm to 230 mm at 25 kV. Thus, only the electrical clearance of 230 mm according to EN 50124 Part 1 (clearance) needs to be maintained.

[0022] In an advantageous further development of the arrangement, it can be provided that the earthed barrier is formed flat.

[0023] This provides a flat shielding, the high-voltage structure.

[0024] In an advantageous development of the arrangement, it can be provided that the grounded barrier is designed in such a way that a low-electric field region is formed on a side of the cladding assembly facing away from the high-voltage assembly, the grounded barrier.

[0025] In the area behind the grounded barrier, in the area of ​​the blue object, there is only a very low field density, where an arc can no longer occur. Therefore, it can penetrate very far into the protective distance (Table 2 of EN 50122-1) without being exposed to any danger.

[0026] In an advantageous further development of the arrangement, it can be provided that an insulating layer is arranged on the side of the cladding assembly facing away from the high-voltage assembly.

[0027] This provides improved protection.

[0028] In an advantageous development of the arrangement, the cladding assembly can have an additional, preferably non-conductive outer cladding element on the side of the cladding assembly facing away from the high-voltage assembly. This provides improved protection. Furthermore, the additional, preferably non-conductive outer cladding element can be freely designed.

[0029] In an advantageous development of the car body, it can be provided that the at least one voltage-carrying component is arranged exposed and touchable on the roof of the car body.

[0030] In an advantageous development of the car body, it can be provided that the cladding assembly is directly connected to the roof of the car body, such that an electrically conductive connection is formed between the extension region, preferably between the distal end of the extension region and the car body, for earthing the earthed barrier.

[0031] This provides an optimal rating for the car body.

[0032] In an advantageous development of the car body, it can be provided that the at least one cladding assembly is arranged in a transition area between the roof and the side wall.

[0033] This makes it possible for the side wall to be extended upwards by the cladding assembly.

[0034] In an advantageous further development of the car body, it can be provided that the earthed barrier extends the side wall in such a way that an object brought to the earthed barrier from the side and from below cannot penetrate into the air gap.

[0035] This ensures that an object brought close to the barrier cannot be reached by an arc generated by the high-voltage assembly.

[0036] All configurations of the arrangement and / or car body apply equally to the track-guided vehicle and vice versa. The invention will be explained below using an exemplary embodiment with reference to the drawing.
