Description

[0001] The invention relates to a support device for at least one rail distributor and a rail distributor with at least one such support device.

[0002] Electrical distribution systems can be designed as busbar systems, also known as busbar distribution systems. In this system, the busbars are elongated and designed as fixed conductors or rails in the direction of current flow. Multiple busbars can be guided and supported within a busbar distribution system and coupled together to form a busbar distribution system. The busbars and their busbar distribution system are used for the transmission and distribution of electrical energy. Typical tasks of a busbar distribution system include, for example, connecting a transformer via a main distribution board to a sub-distribution board or supplying power to large consumers using the busbars.Busbar systems are also used, for example, to direct the electricity generated by a generator in the tower head to the base of the wind turbine, or to transport electricity from the base to the tower head to power the electrical systems there. Busbar systems are suitable for transporting and distributing currents ranging from several hundred to several thousand amperes.

[0003] Typically, the busbars of a busbar distribution system are housed in a busbar enclosure, such as a busbar box or busbar covers. The busbar enclosure serves as mechanical protection and to hold the busbar distribution system components together, and, if required, as a grounded protective earth conductor (PE conductor).

[0004] The busbars – also called conductor rails – inside a busbar housing can be made of copper, aluminum, or similarly conductive materials. Busbars of adjacent segments are typically electrically connected using a bolted connection. For this, the ends of adjacent busbars overlap, and a bolt is inserted that exerts force on the flush ends of the adjacent busbars, pressing them together.

[0005] Another known form of connection between busbars, known from the prior art, is achieved via a so-called terminal block. Each busbar extends horizontally along its length. The busbars are connected via the terminal block, in which each busbar is clamped between two conductive contact surfaces, which in turn are insulated from further contact surfaces by insulating plates.

[0006] The invention is based on the objective of providing a support device for a rail distributor which can absorb a mechanical stress acting on the rail distributor. Furthermore, the object of the invention is to provide a rail distributor with an improved support device.

[0007] The first problem is solved according to the invention by a support device having the features of claim 1. The second problem is solved according to the invention by a rail distributor having the features of claim 11.

[0008] Advantageous further developments of the invention are the subject of the dependent claims.

[0009] The support device according to the invention for at least one rail distributor is characterized by a support and a bearing which is arranged on the support and on which the rail distributor is or can be mounted, wherein the bearing and / or the support are arranged to mount the rail distributor in a manner that allows movement relative to the support.

[0010] The invention is based on the premise that at least one support is required during the installation of busbar trunking systems. A support is understood to be, in particular, a beam that holds the busbar trunking system against a building structure, especially a wall, ceiling, floor, or the like, within a building. During installation, forces may act on the busbar trunking system, and the system may move, particularly in the longitudinal direction.

[0011] The advantages achieved with the invention consist in particular in the fact that, by means of the movable bearing and / or the movable support, the mobility of the rail distribution system can be compensated for or absorbed in both enclosed rail distributors (also called covered rail distributors) and unenclosed rail distributors (also called uncovered rail distributors).

[0012] Preferably, the bearing is modular in design. Alternatively or additionally, the support structure can also be modular.

[0013] In particular, the bearing can be characterized by the scaling of a number of bearing elements. Alternatively or additionally, the support can be characterized by the scaling of a number of support elements. This allows the bearing and / or the support to be individually designed for a multiple of different rail distributors.

[0014] For example, the support and / or the bearing can be characterized by scaling a size, in particular a length, width and / or height, of the rail distributor. In particular, the size of the support device can be scaled by a predetermined number of support elements and / or a predetermined number of bearing elements, in particular adapted to the size of the rail distributor to be accommodated.

[0015] Preferably, the bearing can be designed as a sliding bearing. In particular, the bearing can be designed as a longitudinally sliding bearing. Alternatively or additionally, the bearing can be designed to be sliding in more than one direction.

[0016] In one possible embodiment, the bearing is designed as a plain bearing. Alternatively, the bearing can be designed as a roller bearing or a ball bearing.

[0017] The bearing elements and / or the support elements are made of a material with low frictional resistance. For example, the bearing elements and / or the support elements can be made of steel, plastic, or the like.

[0018] Additionally, at least one bearing element and / or at least one support element can be provided with or supplied with a lubricant. Examples of lubricants used include oil, grease, silicone, perfluoropolyether (PFPE), or similar substances.

[0019] Further development includes a cover that partially or completely surrounds the bearing and the support. Specifically, the cover can be designed as a rail housing, a channel made of fire-resistant building panels, or similar materials. The cover can be made, for example, of cladding panels or similar materials. The cover can be made of a fire-resistant material, such as calcium silicate or similar. The cladding panels can be mounted, for example, using screws or steel wire clamps to form firmly connected open or closed channels. In particular, a cover made of fire-resistant material ensures that the busbars of the busbar distribution system located within the channel remain functional for a defined period in the event of a fire in the building.

[0020] The rail distribution system according to the invention comprises at least one of the support devices described above. In particular, at least one support device is attached to support points of the at least one rail distributor. Several support devices can be arranged one behind the other along an installation direction of the rail distribution system. In particular, several support devices can be arranged side by side. One or more support devices can be provided for each rail distribution system, either side by side or along the installation path, and in particular attached to support points.

[0021] The support device, in particular the bearing and the support, can be arranged within the cover, which is simultaneously designed as a rail housing for the conductor rails.

[0022] The properties, features, and advantages of this invention described above, as well as the manner in which they are achieved, will become clearer and more readily understandable in connection with the following description of exemplary embodiments, which are explained in more detail in conjunction with the drawings. These drawings show: Fig. 1 to Fig. 18 schematically in various representations a first embodiment for a support device of a rail distributor, Fig. 19 to Fig. 23 schematically in various representations a second embodiment for a support device of a rail distributor, Fig. 24 to Fig. 26 schematically in various representations a third embodiment for a support device of a rail distributor, Fig. 27 to Fig. 29 schematically in various representations a fourth embodiment for a support device of a rail distributor, Fig. 30 to Fig. 32 schematically in various representations a fifth embodiment for a support device of a rail distributor, Fig. 33 to Fig. 39 schematically in various representations a sixth embodiment for a support device of a rail distributor, Fig. 40 to Fig. 44 schematically in various representations a seventh embodiment for a support device of a rail distributor, and Fig. 45 to Fig. 50 schematically in various representations an eighth embodiment for a support device of a rail distributor.

[0023] Corresponding parts are marked with the same reference symbols in the figures.

[0024] Fig. Figures 1 to 18 schematically show, in various representations, an embodiment of a first support device 1. I of a rail distributor 2.

[0025] The first support device 1 I comprises a support 4 and a bearing 6, which is arranged on the support 4 and on which the rail distributor 2 is or can be mounted.

[0026] The bearing 6 and / or the support 4 are arranged to mount the rail distributor 2 in a relatively movable manner, in particular longitudinally movable, relative to the support 4.

[0027] All subsequent examples of support devices 1 I up to 1 VIIIEach component comprises a support 4 and a bearing 6, which may differ in detail with regard to the movable mounting of the rail distributor 2, as described below. All bearings 6 described below are designed as sliding bearings 6. All bearings 6 described below can be characterized by scaling a dimension, in particular a length, width and / or height of the rail distributor 2, and thus vary in size.

[0028] The busbar 2 is, in particular, part of an electrical distribution system, especially a busbar distribution system. Several busbars 2.1 can be guided and supported within a busbar 2 and coupled to form a busbar distribution system. For example, the busbars 2.1 are designed as rigid conductors or fixed rails extending in the direction of current flow. The busbars 2.1 and their busbar distribution system are used for the transmission and distribution of electrical energy. Typical tasks of a busbar distribution system include, for example, connecting a transformer via a main distribution board to a sub-distribution board or supplying large consumers or the like by means of the busbars 2.1. The busbars 2.1 are, in particular, made of copper, aluminum, or similar conductive materials. Each busbar 2.1 is designed as a separate rigid profile, in particular a flat profile.

[0029] The busbars 2.1 can be arranged in a busbar enclosure 2.2. The busbar enclosure 2.2 serves as mechanical protection and cohesion for the components of the busbar distribution system 2 and, if required, as a grounded protective conductor (PE conductor). In air-insulated systems, the busbar enclosure 2.2 prevents unwanted electrical contact between the busbars 2.1 and the environment. The busbar enclosure 2.2 is dimensioned such that, firstly, the clearances required to prevent unwanted electrical contact are maintained, and secondly, the busbars 2.1 within the busbar enclosure 2.2 are cooled by natural or forced convection.

[0030] In the "sandwich" system configuration, electrical insulation between the busbars 2.1 (at least between the live conductor and the neutral conductor) and between the busbars 2.1 and the busbar housing 2.2 prevents unwanted electrical contact between the busbars 2.1 and the environment. Cooling is achieved through natural or forced convection from outside the busbar housing 2.2.

[0031] The rail housing 2.2 is, in particular, designed in multiple parts. The rail housing 2.2 can, for example, be box-shaped (not shown in detail). Alternatively, as shown, the rail housing 2.2 can comprise an upper cover profile 2.2.1 and a lower cover profile 2.2.2, as well as side cover profiles (not shown in detail). The upper cover profile 2.2.1 and the lower cover profile 2.2.2 can, for example, be designed as U-shaped sheet metal profiles.

[0032] A support 8 serves in particular to support the bearing 6 and the support 4. The support 8 holds the busbar 2 against a building structure, in particular a wall, ceiling, floor, or the like, within a building. During installation, forces may act on the busbar 2, causing movement, especially in the longitudinal direction x. Due to the resulting high coefficients of friction in conventional supports 8, caused by the high weight of the busbar 2 with its conductor rails 2.1, especially those made of copper, undefined forces may act on the busbar 2, potentially leading to damage. This is reduced or even avoided by means of the movable mounting of the busbar 2 according to the invention, based on the at least one bearing 6 and the at least one support 4.

[0033] By means of the movable bearing 6 and / or the movable support 4, the movement of the rail distributor 2 can be compensated for or absorbed at the support 8, both in the case of an enclosed rail distributor 2 (also called a covered rail distributor, as shown) and in the case of an unenclosed rail distributor 2 (also called an uncovered rail distributor, not shown). The support 8 can, for example, be a fire protection plate.

[0034] Preferably, bearing 6 is modular in design. Alternatively or additionally, support 4 can be modular in design.

[0035] Fig. Figure 2 shows an example of the support 4. The support 4 is designed as a base plate. The support 4 is designed as a U-shaped base plate with two lateral legs 4.1. The legs 4.1 can also be angled outwards. For example, the legs 4.1 can be angled by 90° and / or 180°. This allows the support 4 to be nested or inserted into another component of the support device 1. I be flexibly coupled.

[0036] Fig. Figure 3 shows the rolling element of the bearing 6 of the first support device 1 IA bolt 6.1, for example, made of round steel. The bearing 6 is designed as a rolling bearing or roller bearing. The bearing 6 preferably comprises a plurality of bolts 6.1. The bolts 6.1 are in particular designed as cylindrical rollers or barrel rollers. The bearing 6 can be easily scaled by the number of bolts 6.1 and adapted to the size of the rail distributor 2.

[0037] Fig. Figure 4 shows a guide unit 6.2 (also called a roller unit) for receiving the bolts 6.1. The guide unit 6.2 is designed as a frame 6.2.1 in which the bolts 6.1 can be rotatably mounted. Laterally, a frame opening 6.2.0 (shown in Fig. 20) Bearing surfaces 6.2.2 for the bolts 6.1 and sliding surfaces 6.2.3 are formed.

In addition, the support plate 4.2 has a number of stop elements 4.2.2, in particular tabs, bends, openings or the like, which serve as stop points for the support plate 4.2 on the guide unit 6.2. This is intended to prevent the support plate 4.2 from sliding beyond the guide unit 6.2.
