- the branches can be supplied in full, perforated or forked versions.
- the present invention further relates to a closed busbar system according to the preamble of claim 14.
- Such a module-like structure has in addition to the extremely variable adaptability to planning, subsequent changes and the like the further advantage of economical, quick and easy assembly.
- the busbar system can be quickly produced even after the last project revisions. f) The assembly is faster than other systems because, for example, no time is needed to dry out an insulating material. g) The system is easy to adapt to the various provisions of the local utilities, as various blocks can be easily redesigned and manufactured, which considerably reduces the construction costs. h) The system can be used for main cabinets in which feeders and outlets can be mounted on a mounting plate, as well as for bottom and end distribution cabinets.
- 1 is a schematic plan view of a closed busbar system for three-phase low-voltage distribution according to a preferred embodiment of the present invention
- 2 shows a section along the line II-II of Figure 1
- Figure 4 is a perspective view of the three-phase arrangement of phase and branch rails, as they can be inserted into the module of Figure 3, and
- Figures 5A and 5B are a plan view and a front view, respectively, of two joined insulative housing modules.
- closed busbar system 10 is the one or three-phase voltage distribution in the example low voltage range of 380/400 volts and is arranged on a base plate 11 on a building wall or the like and surrounded by a control cabinet.
- the closed busbar system 10 is suitable for both subdistributor and final distributor. Typical specifications of such busbar systems are given in ANNEX 1.
- the closed busbar system 10 is constructed from a plurality of modules 12 to 15 of an electrical insulating housing, wherein the insulating housings or modules 12 to 15 may be identical or different in that the center distances x and y to be explained are different can.
- FIGS 1 and 2 extend phase rails 16, 17 and 18 over the entire length of the four modules 12 to 15 and the busbar system 10, wherein per module 12 to 15 each three transverse branch rails 21, 22 and 23 are arranged in the Embodiment on both sides protrude from the respective module 12 to 15 and there are provided with mounting holes 24 and 25.
- Each insulating housing module 12 to 15 has, as is apparent from Figure 2 and in particular Figure 3, a base 27, in which the phase rails 16 to 18 are inserted, and a socket cover 28, which covers the transverse branch rails 21 to 23 and receives.
- the base 27 of the insulating housing 12 to 15 on the base plate 11 and the covers 28 are mounted on the sockets 27 strung together.
- the phase rails 16 to 18 are arranged such that between the bottom 31 of the phase rails 16 to 18 and the opposite inner side 32 of the bottom 33 of the base 27, a cooling channel 30 of preferably approximately rectangular cross-sectional configuration results.
- the individual cooling channels 30 in the sockets 27 are in alignment with one another by the arrangement of the plurality of modules 12 to 15 arranged next to each other, so that, according to FIG. 2, a cooling air flow 35 results from bottom to top through the busbar system 10.
- This cooling air flow 35 along the phase rails 16 to 18 can be generated passively or actively by means of a fan.
- each insulating 12 to 15 is made an electrical insulating material, for example of a glass fiber reinforced polyester, which can be processed for example by means of injection molding.
- the base 27 has in the embodiment three parallel spaced grooves 36 to 38, which are identical and have a mirrored to its center plane mirror cross-section.
- the receiving grooves 36 to 38 have two spaced in the direction of the depth of the groove 36 to 38 shoulder pairs 39 and 40, of which the lower shoulder pair 40 of the support of the phase rails 16 to 18 and a certain distance to the base 41 of the receiving groove 36 to 38th having, between the bottom 31 of the phase rails 16 to 18 and the base 41 of the grooves 36 to 38 of the mentioned cooling channel 30 is formed in an approximately rectangular cross-section.
- the distance of the upper shoulder pair 39 to the lower shoulder pair 40 substantially corresponds to the thickness of the phase rails 16 to 18.
- the cover 28 has the base 27 facing transverse recesses 51 which extend over the entire width of the cover 28 and the receiving of the branch rails 21 to 23, so far as they are raised above the phase rails 16 to 18, and the exit from the insulating 12th serve up to 15.
- the cover 28 is screwed onto the base 27, for example, as can be seen on the corresponding holes 52 of the cover 53 of the cover 28 and the holes 54 in the provided between the grooves 36 to 38 longitudinal webs 55 of the base 27.
- the center distances x and y of the branch rails 21 to 23 and thus the recesses 51 in the socket cover 28 and the transverse grooves 47 to 49 of the base 27 may vary according to the switches or the like used.
- Figure 4 shows the perspective arrangement of three branch rails 21 to 23 within a module 12 to 15 on the phase rails 16 to 18.
- the ⁇ bzweigschienen 21 to 23 are bent or folded so that in each case a branch rail 21 to 23, each with a phase bar 16 to 18 electrically contacted and mechanically connected. Otherwise, no contact takes place between the branch rails 21 to 23 and the phase rails 16 to 18.
- the ends of the branch rails 21 to 23 are angled on both sides in the protruding from the insulating housing 12 to 15 ends to the height of the phase rails 16 to 18, where they are connected to further lines and / or switches or the like devices.
- An insulating sheath 56 can be plugged onto a blind end of a branch rail 21 to 23.
- FIG. 3 also shows an upper cover strip 58 and a lower cover strip 59, which strips do not touch each other the modules 12 to 15 but only at the respective end modules 12 to 15, so according to Figure 1 to the upper module 12 and to the lower module 15 are attached.
- the upper cover strip 58 is provided in the region of each cooling channel 30 with pairs of slots 61, while the lower cover strip 59 has a rectangular cross-section slot 62 which is aligned with the cooling channel 30, and a recess 63 through which the respective phase rail 16 to 18 is passed ,
- the insulating overlaid phase rails 16 to 18 end.
- both the base 27 and the cover 28 between the phase rails 16 to 18 and between the branch rails 21 to 23 each have at their ends projecting strips 66, 67, which serve to extend possible creepage distances.
- FIGS. 5A and 5B show an exemplary embodiment of an insulating housing module 12 to 15 to be lined up in the direction of the phase rails 16 to 18.
- a tongue and groove connection in the form of a dovetail connection 71 provided in the sockets 27 of the adjacent modules 12 and 13.
