Definitions
- the present invention relates to a cable support device for switchgear.
- the present invention relates to a cable support device for fixing a plurality of supply cables in a switchgear assembly according to the preamble of claim 1.
- Switchgear and in particular switchgear which include circuit breaker panels, have a plurality of supply cables that must be fixed in a suitable manner in the switchgear. The resulting strain relief ensures that these cables are securely attached to the actual electrical terminal contacts of the circuit breakers.
- cable clamps are usually attached to a base plate of a cable support device in such a way that a supply cable guided between the cable clamp and the base plate is clamped.
- a corresponding number of cable clips must then be attached to the base plate of the cable support device.
- Such cable clamps are very space-consuming due to their shape, in particular due to their fastening tab, which can lead to space problems in the switchgear, especially with a large number of supply cables.
- a variety of different cable clamps and fasteners are known today, which also vary depending on the diameter of the supply cable to be clamped. So that a technician has to assemble the switchgear to fix the cables a correspondingly large number of various tools, cable clamps and fasteners ready, which makes the assembly very expensive.
- the object of the present invention is therefore to provide a cable support device which is space-saving even with a large number of supply cables and which also enables simple assembly.
- the cable support device has a first clamping plate with a largely identical base plate, and in that this first clamping plate can be connected to the base plate with at least two bolts in such a way that that between the clamping surfaces of the base plate and the clamping plate guided supply cables are arranged next to each other in layers and fixed, a space-saving clamping of the supply cables is achieved with the cable support device according to the invention. Since the clamping plate is always connected to the base plate by means of the bolts in such a way that the cables are adequately fixed, the same cable support device can also be used to fix supply cables with different diameters.
- the same cable support device can be used in different types of switchgear, supply cables with a first diameter being used in a first switchgear and supply cables with a second diameter in another switchgear.
- the cable support device preferably has two guides, to which the base plate can be fastened using suitable means and with which the first clamping plate is guided such that it can be moved parallel to the base plate.
- the guides are preferred as parts of the housing
- the cable support device can be prefabricated together with the housing, that is, the base plate fastened to the guides and the clamping plate can be loosely connected to the base plate via the bolts.
- the supply lines they only have to be inserted between the base plate and the clamping plate guided over the guides, and both plates are then only connected with the bolts so tightly that the supply lines are clamped. This significantly reduces the effort involved in installing the switchgear, since no additional installation materials such as cable clamps or fasteners have to be kept in place for fixing the supply lines.
- At least one further clamping plate is provided which has a clamping surface which is largely identical to the first clamping plate and which can be connected to the base plate with the at least two bolts in such a way that the supply cables guided between the clamping surfaces of the first and the further clamping plate are arranged next to one another and be fixed. Then with the cable support device in a first position between the base plate and the first clamping plate leads with a first diameter and in a second position between the first and second Clamping plate leads with a second diameter can be fixed.
- the layers are mounted directly on top of each other, which in turn saves space, especially with a large number of supply lines.
- the bolts can be flexibly attached to any location on the base plate and the clamping plates and thus these plates can be connected accordingly. This means that the attachment can be flexibly adapted to the number or the thickness of the cables that are to be fixed in a position between two plates.
- Fig.2 switchgear with a second embodiment of the cable support device.
- FIG. 1 shows part of the housing of a switchgear assembly S.
- the housing of the switchgear assembly S has an opening at its bottom through which the supply cables L1-L7 are fed to the switchgear assembly S.
- these cables L1-L7 are then, but not shown here, connected to the corresponding contacts, such as the electrical contacts of the individual circuit breakers of a circuit breaker panel.
- the switchgear assembly S in the exemplary embodiment shown has a cable support device at the opening, with which the feeder cables L1-L7 can be fixed, that is to say fixedly attached to the switchgear assembly S.
- the cable support device consists of a base plate G, which has a cable clamping surface FG. Furthermore, the cable support device has a first clamping plate M1, which has a clamping surface FM1 that is largely identical to the base plate G. The largely identical cable clamping surfaces FG and FM1 are ultimately determined by the available space in which the supply cables can be guided through the cable support device. These areas FG and FM1 are shown in dashed lines in FIG. Furthermore, at least two bolts B1 and B2 are provided, which are preferably designed as threaded bolts.
- the first clamping plate M1 can then be connected to the base plate G in such a way that the between the clamping surfaces FG and FM1 of the base plate and the clamping plate led supply cables Ll, L2, L3 and L4 are arranged next to each other and fixed in this position. Since these supply cables have almost the same diameter, a secure fixation of the supply cables and thus a corresponding strain relief in the switchgear is achieved.
- the plates G and Ml are then connected, for example, in that corresponding threads are provided for the threaded bolts on the plates G and Ml, and the plates are screwed together by means of the threaded bolts guided in the threads in such a way that the supply cables L1-L4 between the plates are pinched.
- connection between plate G or Ml with the bolts Bl or B2 can be made by leading the bolts through corresponding perforations in the plates G and Ml and connecting them to the plates G or Ml accordingly by means of a nut and lock nut.
- the specific embodiment shown in FIG. 1 has elongated holes as perforations in the plates G, M1 and M2. These mainly serve to adapt the position of the bolts to the feed lines to be clamped.
- a further clamping plate M2 is provided with a clamping surface FM2.
- the supply cables L5-L7 can then be fixed, that is to say clamped, between the first Ml and the further M2 clamping plate in a second position.
- the different layers can also be used to securely fix cables with different diameters in different layers.
- cable L1-L4 have a first diameter and the supply cable L5-L7 have a different diameter.
- FIG. 1 A further stage of expansion with additional clamping plates for further supply cables is indicated by dashed lines in FIG. 1.
- the clamping plates G, M1, M2 etc. are connected to one another via the two common bolts B1 and B2. Additional bolts can be provided as indicated in FIG. 1, in order to connect the plates additionally between the feed lines arranged next to one another, particularly in the case of wide clamping surfaces FG, FM1, FM2, in order to increase the stability of the fixation.
- FIG. 2 shows another embodiment of the cable support device according to the invention.
- a base plate G, a first clamping plate M1 and a further clamping plate M2 are provided here.
- the supply cables L1 -L4 are routed between the base plate G and the first clamping plate Ml and the supply cables L5 and L ⁇ between the clamping plate Ml and the clamping plate M2.
- four bolts B1-B4 are provided here, as well as two nuts MB1 and MB2 on the base plate G and two nuts MB3 and MB4 on the first clamping plate M1.
- the first clamping plate M1 is connected to the base plate G via the bolts B1 and B2 and the nuts MB1 and MB2 in such a way that the leads L1-L4 can be fixed accordingly.
- the second clamping plate M2 is connected to the first clamping plate M1 via the bolts B3 and B4 and the nuts MB3 and MB4 in such a way that the leads L5 and L6 are fixed accordingly.
- This embodiment then enables, for example, first a first layer of cables, namely L1-L4, which have a common first diameter, to be fixed in the cable support device and only then next layer can be fixed with the supply cables L5 and L6.
- the fixing of the cables can be simplified during assembly, since not all cables have to be led through the cable support device and braced at once.
- a third and also further clamping plates can also be specified in the second exemplary embodiment, which are connected to the adjacent clamping plate via correspondingly further bolts.
- the cable support device according to the invention can also comprise a plurality of base plates and clamping plates attached to them.
- the features of the two exemplary embodiments described and shown in FIGS. 1 and 2 can also be easily combined with one another.
- a third clamping plate can be attached to a second clamping plate with two bolts. This second clamping plate is then fastened together with the first clamping plate to the base plate via two further bolts.
- the bolts can also have other suitable shapes, such as, for example, a clamping bolt shape. Many other embodiments are thus conceivable as long as only the basic idea of the present invention, namely a number of supply cables in layers between plates, is to be clamped in a space-saving and simple manner.
