Abstract
A multiphase electrical busbar for the connection of electrical service devices is described, which has one flat ribbon conductor (59, 60, 61) per phase, on which connecting lugs (62, 82, 83) are integrally formed at right angles to the flat ribbon plane. The flat ribbon conductors (59 to 61) are accommodated in a dielectric housing (50), in which chambers (56, 57, 58) are formed which are respectively used to accommodate a flat ribbon conductor (59, 60, 61). In order to avoid phase-to-phase shorts caused by condensed water, the connecting lugs (62, 82, 83) are connected via a U-shaped bend (63, 66, 67) to the flat ribbon conductors (59, 60, 61), in such a manner that each connecting lug (62, 82, 83) in each case forms a first limb of the U-shape, and the flat ribbon conductors (59, 60, 61) are connected to the other limb, at right angles to it. The open side of the U-shapes (63, 66, 67) is open towards the connecting lugs (62, 82, 83).
Description
Multiphase electrical busbar Description The invention relates to a multiphase electrical busbar for the connection of electrical service devices according to the precharacterizing clause of Claim 1.
Figures 1 to 3 show electrical busbars which are known per se and have been in use for a long time. Figure 1 shows a perspective view and Figure 2 the plan view of such a multiphase electrical busbar, having a housing 10 which has three chambers 11, 12 and 13, of which the chambers 12 and 13 as well as 11 and 13 are separated from one another by means of intermediate walls 14 and 15, respectively. Flat ribbon conductors 16, 17 and 18 are inserted as busbars into the chambers 11, 12 and 13, of which busbars the central busbars 18 lie, with straight connecting lugs 19A, 19B, 19C and 19D in a plane with the busbar and with the flat ribbon conductor 18. The busbar formed by the flat ribbon conductor 17 has connecting lugs 20A, 20B, 20C and 20D
which lie in the plane of the connecting lugs 19A to 19D and are connected by means of connecting sections 21 to the flat ribbon bar 17. The connecting lugs 22A, 22B, 22C and 22D which are connected in a similar manner to the busbar 16 are connected by means of obliquely running connecting sections 23 to the busbar 16 in order that the connecting lugs likewise lie in the plane of the connecting lugs 19A to 19D; 20A to 20D.
The distance between the flat ribbon conductors 16, 17 and 18 is in each case chosen such that, when being cut to length, which is done by sawing, bridging between the individual flat ribbon conductors 16 to 18 is prevented and a minimum permissible insulation separation is not infringed.
Figures 1 to 3 show electrical busbars which are known per se and have been in use for a long time. Figure 1 shows a perspective view and Figure 2 the plan view of such a multiphase electrical busbar, having a housing 10 which has three chambers 11, 12 and 13, of which the chambers 12 and 13 as well as 11 and 13 are separated from one another by means of intermediate walls 14 and 15, respectively. Flat ribbon conductors 16, 17 and 18 are inserted as busbars into the chambers 11, 12 and 13, of which busbars the central busbars 18 lie, with straight connecting lugs 19A, 19B, 19C and 19D in a plane with the busbar and with the flat ribbon conductor 18. The busbar formed by the flat ribbon conductor 17 has connecting lugs 20A, 20B, 20C and 20D
which lie in the plane of the connecting lugs 19A to 19D and are connected by means of connecting sections 21 to the flat ribbon bar 17. The connecting lugs 22A, 22B, 22C and 22D which are connected in a similar manner to the busbar 16 are connected by means of obliquely running connecting sections 23 to the busbar 16 in order that the connecting lugs likewise lie in the plane of the connecting lugs 19A to 19D; 20A to 20D.
The distance between the flat ribbon conductors 16, 17 and 18 is in each case chosen such that, when being cut to length, which is done by sawing, bridging between the individual flat ribbon conductors 16 to 18 is prevented and a minimum permissible insulation separation is not infringed.
In the case of the electrical busbar, known per se, as shown in Figure 3, which shows the busbar in cross section, a dielectric housing 30 is likewise provided, having a plurality of chambers 31, 32 and 33 which are located one above the other or alongside one another and are separated from one another by means of partition walls 34 and 35 running in a zig-zag shape.
The chambers 31, 32 and 33 contain flat ribbon conductors 36, 37 and 38 as busbars, on which connecting lugs 40, 41 and 42 are integrally formed, which run at right angles to the plane of the flat ribbon conductors 36 to 38; the connecting lugs 40, 41 and 42 are of different lengths in order that service devices of the same phase can be connected to one another by means of a single electrical busbar, so that they are at the same potential.
In both arrangements, a problem arises in that condensed water can form as a result of atmospheric influences on the connecting lugs 19, 20, 22 and 40, 41, 42, which condensed water can, for example, flow into the individual chambers in the form of a water droplet. The water droplet shown in Figure 2 runs on the outer surface of the partition wall 14 into the chamber 12; under some circumstances, this water droplet forms a connection from the busbar 17 to the busbar 18, so that a phase-to-phase short can occur here.
In the configuration in Figure 3, a water droplet 43 can be formed on a busbar and can be drawn by capillary action into the chamber 32 in the direction of the arrow P1, which can likewise result in a phase-to-phase short between the busbars 36 and 37 or the busbars 37 and 38.
The object of the invention is to provide a solution which prevents condensed water from being able to lead to a phase-to-phase short.
The chambers 31, 32 and 33 contain flat ribbon conductors 36, 37 and 38 as busbars, on which connecting lugs 40, 41 and 42 are integrally formed, which run at right angles to the plane of the flat ribbon conductors 36 to 38; the connecting lugs 40, 41 and 42 are of different lengths in order that service devices of the same phase can be connected to one another by means of a single electrical busbar, so that they are at the same potential.
In both arrangements, a problem arises in that condensed water can form as a result of atmospheric influences on the connecting lugs 19, 20, 22 and 40, 41, 42, which condensed water can, for example, flow into the individual chambers in the form of a water droplet. The water droplet shown in Figure 2 runs on the outer surface of the partition wall 14 into the chamber 12; under some circumstances, this water droplet forms a connection from the busbar 17 to the busbar 18, so that a phase-to-phase short can occur here.
In the configuration in Figure 3, a water droplet 43 can be formed on a busbar and can be drawn by capillary action into the chamber 32 in the direction of the arrow P1, which can likewise result in a phase-to-phase short between the busbars 36 and 37 or the busbars 37 and 38.
The object of the invention is to provide a solution which prevents condensed water from being able to lead to a phase-to-phase short.
This object is achieved according to the invention by the features of Claim 1.
According to this, the connecting lugs are connected in an advantageous manner via a U-shaped bend to their associated flat ribbon conductor, in such a manner that each connecting lug forms in each case one first limb, and the flat ribbon conductors are connected to the other limb at right angles to it.
Since the open sides of the U-shape point upwards, since the connecting lugs run vertically and the flat ribbon conductors run horizontally in the installed position, the water which condenses on the connecting lugs can run downwards into the U-shape, but it is prevented from getting into the individual chambers-of the dielectric profile, and thus producing a phase-to-phase short.
Corresponding to the U-shapes, which are bent downwards - in the installed position - the outer wall of the chamber of the dielectric profile or of the dielectric housing located opposite the connecting lugs is expanded in the form of a groove, so that a channel is formed there in which condensed water can collect in the installed position. In order that this water can also flow away, there are openings at the lowest point of the channel, through which the condensed water can flow away in the installed position.
Further advantageous refinements and improvements of the invention can be found in the other dependent claims.
The invention as well as further advantageous refinements and improvements of the invention, and further advantages, are explained and described in more detail with reference to the drawing in which, on the one hand, the prior art described above is also illustrated. In the figures:
Figures 1 to 3 show various busbars according to the prior art, Figure 4 shows a cross-section view through a busbar according to the invention, Figures 5 and 6 show a busbar according to the invention in the folded open and closed state, and Figures 7 to 8 show two perspective views, each of a further embodiment of a busbar according to the invention.
Reference will now be made to Figure 4.
Figure 4 shows, schematically, a cross section through a busbar according to the invention, which has a dielectric housing 50, which has two end walls 51 and 52 which form a U-shape with a base wall 53;
intermediate walls 54 and 55 project from the base wall 53, which results in chambers 56, 57 and 58 being formed, in which flat ribbon conductors 59, 60 and 61 are located, which are provided with connecting lugs 62. The other connecting lugs, those for the flat ribbon conductors 60 and 61, are concealed in Figure 4.
All these connecting lugs are connected to their associated flat ribbon conductors 59 as is illustrated for the busbar which can be seen: a U-shape 62 is connected to the flat ribbon conductor 59, with one limb 64 of the U-shape merging into the connecting lug 22 and forming the connecting lug 22, while, in contrast, the other limb 65 is connected to the flat ribbon inductor 59 which runs roughly at right angles to it. The connecting lugs of the other flat ribbon conductors 60 and 61 are connected to a U-shape 66 or 67, which corresponds to the U-shape 63, and which, as is evident from Figure 4, are staggered downwards corresponding to the distance between the flat ribbon conductors 59, 60, 61. The U-shapes are open in a direction which runs at right angles to the planes of the flat ribbon conductors in the direction of the connecting lugs.
The lower terminating wall 52 has a bend 68 in the form of a groove with a channel base 70 which is located -in the installed position - underneath the wall 52, and to whose free end a wall 71 is connected, which wall 71 runs at right angles to the partition walls 54 and 55 and to the terminating walls 51 and 52 and considerably overhangs the upper wall 51, so that the base wall 53 is smaller than the covering wa11.71. This results in a channel 69 being formed, whose channel base 70 is provided with openings 72.
If a water droplet 73 is now formed on the connecting lug 62, then the water droplet 73 can run into the U-shape 63; the water droplet 73A denoted by dots there can drip onto the channel base 70, and can flow out through the opening 72. This prevents a phase-to-phase short between the individual busbars or flat ribbon conductors of different phases.
All the sections of the dielectric housing 50 are integrally connected to one another, so that, for assembly, the busbars must be pushed in their longitudinal direction into the chambers 56, 57 and 58.
It is self-evident that the partition walls 54 and 55 are designed so as to ensure a sufficient distance between the flat ribbon conductors 59, 60 and 61.
Reference is now made to Figure 5. A dielectric housing 80 contains chambers which are arranged one above the other, correspond to the chambers 56 to 58 and are covered by the upper terminating wall 81, so that they cannot be seen. The flat ribbon conductors 59, 60 and 61 are inserted into the chambers, although they likewise cannot be seen, and the connecting lugs 62, 82 and 83 are formed on them, although they cannot be seen in Figure 4. However, the individual U-shapes of the connecting lug can be seen well, namely the U-shape 63 of the connecting lugs 62, the U-shape 66 of the connecting lug 82, and the U-shape 67 of the connecting lug 83. A flap 84 corresponding to the wall 71 is connected such that it can rotate to the wall that corresponds to the lower wall 52 and which cannot be seen in Figure 5, with hinges (which are not shown in any more detail) being provided which are produced, for example, by means of a film hinge or by hooking the covering flap 84 into appropriate openings. In this case, the flap 84 has a strip 85 which is integrally formed at right angles to the flap plane and in which openings 86 are provided which are used, in the same way as the openings 72, for any condensed water to flow out.
Since the busbars and the flat ribbon conductors can be inserted into their chambers in the direction of the arrow P2, the dielectric housing 80 can be terminated even from the start at the end faces by a terminating wall 87 and 88 which runs at right angles to the chambers 56 and is integrally connected to the housing 80.
Figure 6 shows the arrangement according to Figure 5 in closed form; the flap 84 is folded up at right angles to the chambers and parallel to the connecting lugs, with latching tabs (87) which are integrally formed on the upper terminating wall 81 passing through openings 88 in the flap 84. The strip 85 then runs horizontally, so that the condensed water can flow away outwards through the openings 86.
Figure 7 shows a further refinement of the invention.
The multiphase busbar has a dielectric housing 90, whose chambers 91, 92 and 93 can be seen on the right.
The flat ribbon conductors are pushed into these chambers 91 to 93, which correspond to the chambers 56 to 58 in Figure 4; the connecting lugs 62, 82 and 83 are proud of the upper covering wall 94 of the insulating housing 90. A wall 96 which corresponds to the wall 71 is integrally formed on the lower terminating wall, in the same way as that illustrated in Figure 4, so that the flat ribbon conductors must be pushed in their longitudinal direction via one of the end faces into the chambers 91 to 93. Once the individual connecting lugs 62, 82 and 83 have been aligned correctly with respect to one another, the open end faces are closed.by means of cover plates 97 and 98, whose contour corresponds to the circumferential contour of the dielectric housing 53.
Figure 6 shows that the end walls 87 and 88 as well as the cover plates 87 and 88 are proud of the flap 84, so that the edges 87A and 88A, which run parallel to the connecting lugs, are aligned with the outer surface of the flap 84. The cover plates 97 and 98 can be latched; it is also possible for them to be attached by ultrasound welding etc.
In other words: the connecting lugs 62, 82, 83 form a U-shape 63, 66, 67 with the flat ribbon conductors 59, 60 and 61, as seen from the end face, with the flat ribbon conductors 59, 60, 61 being aligned as limbs at right angles to the connecting lugs 62, 82, 83.
Figure 8 shows a perspective illustration of a multiphase busbar 100 whose upper terminating wall 101 - in the installed position - has cutouts 211 on its free edge 102, into which connecting lugs 103 and 104 engage, and are used for fixing the flat ribbon conductors against movement along their longitudinal axis. The covering flap 105 which corresponds to the covering flap 89 has a plurality of openings 106, through which the busbar can be ventilated.
According to this, the connecting lugs are connected in an advantageous manner via a U-shaped bend to their associated flat ribbon conductor, in such a manner that each connecting lug forms in each case one first limb, and the flat ribbon conductors are connected to the other limb at right angles to it.
Since the open sides of the U-shape point upwards, since the connecting lugs run vertically and the flat ribbon conductors run horizontally in the installed position, the water which condenses on the connecting lugs can run downwards into the U-shape, but it is prevented from getting into the individual chambers-of the dielectric profile, and thus producing a phase-to-phase short.
Corresponding to the U-shapes, which are bent downwards - in the installed position - the outer wall of the chamber of the dielectric profile or of the dielectric housing located opposite the connecting lugs is expanded in the form of a groove, so that a channel is formed there in which condensed water can collect in the installed position. In order that this water can also flow away, there are openings at the lowest point of the channel, through which the condensed water can flow away in the installed position.
Further advantageous refinements and improvements of the invention can be found in the other dependent claims.
The invention as well as further advantageous refinements and improvements of the invention, and further advantages, are explained and described in more detail with reference to the drawing in which, on the one hand, the prior art described above is also illustrated. In the figures:
Figures 1 to 3 show various busbars according to the prior art, Figure 4 shows a cross-section view through a busbar according to the invention, Figures 5 and 6 show a busbar according to the invention in the folded open and closed state, and Figures 7 to 8 show two perspective views, each of a further embodiment of a busbar according to the invention.
Reference will now be made to Figure 4.
Figure 4 shows, schematically, a cross section through a busbar according to the invention, which has a dielectric housing 50, which has two end walls 51 and 52 which form a U-shape with a base wall 53;
intermediate walls 54 and 55 project from the base wall 53, which results in chambers 56, 57 and 58 being formed, in which flat ribbon conductors 59, 60 and 61 are located, which are provided with connecting lugs 62. The other connecting lugs, those for the flat ribbon conductors 60 and 61, are concealed in Figure 4.
All these connecting lugs are connected to their associated flat ribbon conductors 59 as is illustrated for the busbar which can be seen: a U-shape 62 is connected to the flat ribbon conductor 59, with one limb 64 of the U-shape merging into the connecting lug 22 and forming the connecting lug 22, while, in contrast, the other limb 65 is connected to the flat ribbon inductor 59 which runs roughly at right angles to it. The connecting lugs of the other flat ribbon conductors 60 and 61 are connected to a U-shape 66 or 67, which corresponds to the U-shape 63, and which, as is evident from Figure 4, are staggered downwards corresponding to the distance between the flat ribbon conductors 59, 60, 61. The U-shapes are open in a direction which runs at right angles to the planes of the flat ribbon conductors in the direction of the connecting lugs.
The lower terminating wall 52 has a bend 68 in the form of a groove with a channel base 70 which is located -in the installed position - underneath the wall 52, and to whose free end a wall 71 is connected, which wall 71 runs at right angles to the partition walls 54 and 55 and to the terminating walls 51 and 52 and considerably overhangs the upper wall 51, so that the base wall 53 is smaller than the covering wa11.71. This results in a channel 69 being formed, whose channel base 70 is provided with openings 72.
If a water droplet 73 is now formed on the connecting lug 62, then the water droplet 73 can run into the U-shape 63; the water droplet 73A denoted by dots there can drip onto the channel base 70, and can flow out through the opening 72. This prevents a phase-to-phase short between the individual busbars or flat ribbon conductors of different phases.
All the sections of the dielectric housing 50 are integrally connected to one another, so that, for assembly, the busbars must be pushed in their longitudinal direction into the chambers 56, 57 and 58.
It is self-evident that the partition walls 54 and 55 are designed so as to ensure a sufficient distance between the flat ribbon conductors 59, 60 and 61.
Reference is now made to Figure 5. A dielectric housing 80 contains chambers which are arranged one above the other, correspond to the chambers 56 to 58 and are covered by the upper terminating wall 81, so that they cannot be seen. The flat ribbon conductors 59, 60 and 61 are inserted into the chambers, although they likewise cannot be seen, and the connecting lugs 62, 82 and 83 are formed on them, although they cannot be seen in Figure 4. However, the individual U-shapes of the connecting lug can be seen well, namely the U-shape 63 of the connecting lugs 62, the U-shape 66 of the connecting lug 82, and the U-shape 67 of the connecting lug 83. A flap 84 corresponding to the wall 71 is connected such that it can rotate to the wall that corresponds to the lower wall 52 and which cannot be seen in Figure 5, with hinges (which are not shown in any more detail) being provided which are produced, for example, by means of a film hinge or by hooking the covering flap 84 into appropriate openings. In this case, the flap 84 has a strip 85 which is integrally formed at right angles to the flap plane and in which openings 86 are provided which are used, in the same way as the openings 72, for any condensed water to flow out.
Since the busbars and the flat ribbon conductors can be inserted into their chambers in the direction of the arrow P2, the dielectric housing 80 can be terminated even from the start at the end faces by a terminating wall 87 and 88 which runs at right angles to the chambers 56 and is integrally connected to the housing 80.
Figure 6 shows the arrangement according to Figure 5 in closed form; the flap 84 is folded up at right angles to the chambers and parallel to the connecting lugs, with latching tabs (87) which are integrally formed on the upper terminating wall 81 passing through openings 88 in the flap 84. The strip 85 then runs horizontally, so that the condensed water can flow away outwards through the openings 86.
Figure 7 shows a further refinement of the invention.
The multiphase busbar has a dielectric housing 90, whose chambers 91, 92 and 93 can be seen on the right.
The flat ribbon conductors are pushed into these chambers 91 to 93, which correspond to the chambers 56 to 58 in Figure 4; the connecting lugs 62, 82 and 83 are proud of the upper covering wall 94 of the insulating housing 90. A wall 96 which corresponds to the wall 71 is integrally formed on the lower terminating wall, in the same way as that illustrated in Figure 4, so that the flat ribbon conductors must be pushed in their longitudinal direction via one of the end faces into the chambers 91 to 93. Once the individual connecting lugs 62, 82 and 83 have been aligned correctly with respect to one another, the open end faces are closed.by means of cover plates 97 and 98, whose contour corresponds to the circumferential contour of the dielectric housing 53.
Figure 6 shows that the end walls 87 and 88 as well as the cover plates 87 and 88 are proud of the flap 84, so that the edges 87A and 88A, which run parallel to the connecting lugs, are aligned with the outer surface of the flap 84. The cover plates 97 and 98 can be latched; it is also possible for them to be attached by ultrasound welding etc.
In other words: the connecting lugs 62, 82, 83 form a U-shape 63, 66, 67 with the flat ribbon conductors 59, 60 and 61, as seen from the end face, with the flat ribbon conductors 59, 60, 61 being aligned as limbs at right angles to the connecting lugs 62, 82, 83.
Figure 8 shows a perspective illustration of a multiphase busbar 100 whose upper terminating wall 101 - in the installed position - has cutouts 211 on its free edge 102, into which connecting lugs 103 and 104 engage, and are used for fixing the flat ribbon conductors against movement along their longitudinal axis. The covering flap 105 which corresponds to the covering flap 89 has a plurality of openings 106, through which the busbar can be ventilated.
