description

Switchgear panel The invention relates to a switchgear cubicle with a extending in the direction of a transverse axis of the busbar section for connection of at least two distributive device ^¬ genschaltfeider, wherein the busbar section several, in particular three or integral multiples, extending in the direction of the transverse axis phase conductor housing for on ^¬ takeover of phase conductors, wherein at least one of the phase conductor housing has at least one interface, which is followed by a housing module. Such a switchgear panel is known, for example, from the product publication "Gas-insulated switchgear of 72.5 to 800 kV" from Siemens AG, where it is proposed to construct a switching field such that several phase conductor ^housings which project in the direction of a transverse axis on a switchgear panel extend, are supported on different ports. It is provided that passes depending on the position of the various phase conductors housing in each case a specific ge ^¬-curved housing module for use. As a result, an almost arbitrary arranging the phase conductors housings of the individual phase conductor possible. Thus, although a high Va ^¬ achieved riabilität in the design of the switchgear fields for different application variants, however, the number of necessary different housing blocks for supporting the different phase conductor housing is comparatively large.

Therefore, a distributive device ^¬ genschaltfeld obtained as the object of the invention to specify which allows for reduced number of variants of housing modules for supporting Phasenleiter- further housings a high variability in the Ausgestal ^¬ processing of the switchgear cubicle. According to the invention the object is achieved in a switchgear switch box of the type mentioned in that at least one of the interfaces of a phase conductor housing is connected to a Y-housing block.

Through the use of a Y-housing block, a housing ^{¬ building} block is created, which has at least three branches in a projection, which protrude ^¬ in different directions. The projection should be done in the installation position of the Y housing block in the direction of the transverse axis of the switch panel. The transverse axis is the axis along which a busbar extends, from which switchgear switch panels extend in a stitch-like manner essentially perpendicular to the transverse axis. The busbar section of a switchgear panel crosses / spans in particular advantageously in the direction of the transverse axis successive phases. In particular, the bus bar section can transversely to several volatile ^¬ tend arranged breaker housings of the switchgear are genschaltfeldes. A Y-housing module provides a housing, in the interior of which at least one phase conductor is arranged. The phase conductor branches (possibly switchable / switchable) between at least three branches of the Y-housing. Branches of the Y-housing block are example ^¬ formed by connecting pieces. The nozzles serve to bind an input / connecting the Y-housing module with further Gehäu ^¬ sen. The sockets represent interfaces of the Y housing component. The Y housing component preferably has a fluid-tight housing. It can be provided, for example, that the individual branches of the Y-housing block are arranged axially staggered in the direction of the transverse axis. Wei ^¬ ter can be provided that the branches of the Y-Gehäusebau ^¬ stone are aligned with respect to the transverse axis on a circuit in alignment with ^¬ each other. In particular, in the case of an axial offset, it is possible, for example, for a vertex of the individual branches (projecting in a projection) to be provided in the direction of the transverse axis in the form of a substantially hollow-cylindrical basic body in whose lateral surface Chen essentially the individual branches of the Y-block housing are arranged perpendicularly of the cylinder axis fortra ^¬ quietly. Alternatively, it can also be provided that the individual branches are aligned in a circulation around a transverse axis

(radiating) are arranged and the branches of the Y

Housing blocks merge together at the apex, so that in the vertex of a limited by the individual branches volume is encompassed. For example, it can also be advantageously provided in this case that the top area is widened in the manner of a spherical cap, wherein the individual branches are advantageously radially aligned in a plane of a diameter. The branches should preferably be designed as substantially hollow cylindrical neck. Relative positions, angle specifications, center points, etc. refer in this case to cylinder axes of the nozzles. The stubs of the Y-housing should preferably be formed opposite to the interfaces of the phase conductor housing of the busbar section or further housing.

Accordingly, the possibility is given, for example, to ^{¬ at} least on one of the branches of the Y-housing block, the Posi ^¬ tioning at least make a phase conductor housing. Advantageously, support for one or more phase conductor housings can also be provided on two of the branches. Unused branches of the Y housing block can be closed at the end. For this purpose, for example, a flange cover a neck. For connection of a phase conductor case with the Y-housing module while an attachment of an interface of the Phasenleiterge ^¬ housing is advanta- geous to provide a nozzle of the Y-housing block. A nozzle can be designed, for example, as a welding nozzle, adhesive nozzle or as a nozzle in flange, etc. For example, a connecting piece can be made substantially hollow-cylindrical, in particular hollow-cylindrical circular. An interface of a phase conductor housing can on the shell side to preferably substantially hollow cylindrical be arranged risch formed phase conductor housings of the busbar section. In this case, the Zylin ^¬ derachse of the phase conductor housing is substantially parallel to the transverse axis. An interface of a phase conductor housing of the busbar section for connection to other Ge ^¬ housings can be designed as a nozzle. This interface should preferably be on the shell side. The busbar section can be designed as a single busbar or as a multiple busbar, in particular as a double busbar. The busbar section can be made single-phase or multi-phase. Within a Phasenleiterge ^¬ housing one or more phase conductors may be included. In an inclusion of multiple phase conductors within a common housing, this can result in the same electric potential (same phase, single-pole isolation), or different electrical potentials lead (several Pha ^¬ sen, multi-pole isolation). A composite of Y-package and phase conductor housing should be made fluid-tight, so that phase conductors within the housing surrounding fluid can not escape. The housings themselves should be designed as fluid-tight pressure vessels. Inside the housing for transporting an electric current provided phase ^¬ conductors are of an electrically insulating fluid, such as sulfur hexafluoride gas, nitrogen gas, an oil, etc. lapped. Advantageously, the fluid can have a pressure on ^¬.

Preferably, the switchgear panel should be designed as a pressurized gas or pressure fluid-insulated system, so that the phase conductors are arranged within a pressurized electrically insulating fluid, for example an insulating gas such as sulfur hexafluoride or nitrogen or an insulating ester or an insulating oil. The corresponding housings, in particular the phase conductor housing and the Y housing component, surround the electrically insulating fluid and form a pressure-resistant barrier for the fluid. Likewise, the Y-housing block can be part of a pressure-resistant barrier be, wherein a guided within a phase conductor housing ^¬ ter phase conductor can protrude electrically insulated in at least one of the branches. The use of a Y-block housing enables ver ^¬ different phase conductor housing using a support and the same embodiment of the Y-block housing in different positions. For example, an asymmetrical design of the Y-housing block may be provided in order to rotate at a 180 ° rotation, for example around a branch of the Y-housing.

Housing blocks to produce mirror-symmetric layers. Because of ^¬ given the opportunity to use one and the same Y-housing block several times to a switchgear panel. For example, it can be provided that the switchgear panel is designed multiphase, particularly three phase, that is, a switchgear cubicle has meh ^¬ eral phase conductors which are electrically insulated from one another, wherein the individual phase conductors of each via ^¬ weils associated phase conductor housing and guided therein phase conductor of a Busbar section with other Pha ^¬ senleitern further Schaltwerksschaltfeider are connectable. The busbar section is advantageously transverse to the sequence of the individual phases of the switchgear panel. In particular, in the use of three-phase executed Schaltanlagenschaltfeidern is possible by various positioning and dessel ^¬ ben Y housing block to hold and as a mechanical spacing of the phase conductor housing besides located therein phase conductors several, in particular at least two of the phase conductors / phase conductor housing at different Po ^¬ sitions to ensure. At least the Y-housing module and especially the phase conductor casing of Sammelschienenabschnit ^¬ tes should be carried out single-pole insulated. In this Fal ^¬ le fluid isolation is limited in each case by a housing, wherein within the fluid quantity in each case only one phase conductor of a phase (of a pole) is / are arranged. An advantageous embodiment can provide that the Y-housing module has a base branch and a first and second support branch, wherein the support branches enclose an angle of about 135 °.

A Y-housing module having a base branch and a first and a second support leg is preferably such incorporated ^¬ is that the base branch is set as a force receiving element is a ^¬, wherein the support branches least each feed taking a phase conductor housing of a phase conductor inserted ^¬ puts his can , Thus, the forces emanating from the phase conductor housings, which can be arranged on the support branches, can be introduced into the base branch. As can be ^¬ provided that both the first and the second support branch or even only one of the support branches with egg ^¬ nem phase conductor housing of the busbar section verbun ^¬ the.

Use of a between the support branches eingeschlos- Senen angle of 135 ° allows for a corresponding positio ^¬ discrimination of the Y-housing module via its base branch ver ^¬ different type costs incurred by the support branches of the Y-Gehäusebau ^¬ stone. Thus, a spacing Various ^¬ ner phase conductor along with housing lying in phase conductor on a circular path is possible, for example, the circular pitch is 45 ° or a multiple thereof. For example, three different phase conductor housings, six different phase conductor housings or nine different phase conductor housings can be arranged in a grouped manner distributed over a full circle, wherein the phase conductor housings of a group are each arranged offset by 45 ° zueinan ^¬ . The circular path should rotate around the transverse axis of the switchgear panel coaxially. Each group should be distributed ^{symmetrically} within a circle sector of 90 °. The angle limbs delimiting the respective circular sector (which enclose the angle of 90 °) should be swung out of a vertical or horizontal so that in each case at least in each case one of the phase conductor housing of the first group and the two ^¬ th group lie with their axes in a common horizontal or in a common vertical plane. It is preferable for each of the phase conductor housings of one group to be associated with a phase conductor housing of the other group, each lying in one plane. The planes should be parallel or perpendicular to each other. In particular, for this purpose, the groups or their circular sectors should be swung in opposite directions by 22.5 ° from a horizontal or vertical (see in particular Figures 2, 11, 12, 13).

A further advantageous embodiment can provide that the two support branches are aligned asymmetrically to the base branch.

By an asymmetrical configuration of the Y-housing ^¬ teines it is possible to align the base branch preferably in the vertical or horizontal direction and in particular to rotate 180 ° about the cylinder axis of the base branch, so that with respect to a rotation axis after rotation by 180 ° on both sides this axis counter-spreading

Support branches are present at aligned base branches axially one behind the other lying Y-housing blocks. A rotation axis should preferably lie in a vertical or horizontal.

A further advantageous embodiment can provide that the two support branches are aligned symmetrically to the base branch. In addition to an asymmetrical design of the Y-housing block, it is also possible to provide a symmetrical configuration of a Y-housing block. In this case, would be given a rotation of 180 ° of the Y-housing block to the Zylin ^¬ derachse of the base branch in a projection in the direction of the transverse axis, regardless of rotation, a constant contour of the Y-housing block. Especially with a combination of asymmetric and symmetrical th Y-housing blocks is then the possibility of a three-phase ^¬ engineered switchgear cubicle using two different Y-housing components in support of a three-phase busbar section execute. The phase conductor housings extending in the direction of the transverse axis, for example substantially in the manner of hollow cylinders, can be aligned parallel to one another, wherein these

Phase conductor housing each having approximately the same distance from the vertex of the Y-housing blocks. Correspondingly, a position of the phase conductor housings in the manner of a cage results, wherein the phase conductor housings delimiting the cage are distributed on a circular path around the Y housing modules. The vertices of the Y-housing ^¬ blocks should define the transverse axis and form the center point of the circular path.

Furthermore, it can be advantageously provided that, in a sequence in the direction of the transverse axis with aligned base branches, a symmetrical Y-housing module is flanked by asymmetrical Y-package modules.

In the embodiment of a switchgear panel having a plurality of phase conductor housings of a busbar section, a flanking of a symmetrical Y-housing construction flank of asymmetrical Y-housing blocks can be flanked on both sides, in particular in the direction of the transverse axis. The individual phase conductor housing of the busbar section can be positioned distributed on a circular path. Preferably, two different design variants, namely to use a symmetrical and two preferably asymmetrically shaped Y-housing blocks. The base branches should be aligned one behind the other, wherein a symmetrical Y-housing block is arranged between the two asymmetric Y-housing blocks. The two asymmetric Y-housing blocks should have respect to the base branch mirror-inverted supporting branches, wherein in a projection in the direction of the transverse axis, a support branch of the symmetrical housing block as Angle bisector lies between the respective support branches of the flanking asymmetric Y-housing blocks. In this case, the position of the individual support branches is selected such that different phase conductor housings (in particular 3) are distributed symmetrically, for example, on a quadrant. The

Quarter circle limiting legs should be arranged differently from a vertical position as well as different from a horizontal position. Preferably, a pivoting of the four ^¬ telkreises from a vertical or horizontal by 22.5 ° should follow. An integer multiple of 22.5 ° in turn gives a pitch of 45 ° or of 135 °, so that there is a simplified modular design of the switchgear panel. In adjacent to each other arranged essentially equal be built switching fields (which are connected across a bus bar) are adjacent to each other Y-housing modules are preferably each embodied asymmetrically, wherein an opposite mirror-image position of the immediately Benach ^¬ disclosed asymmetric Y-housing modules should be provided.

A further advantageous embodiment can provide that the phase conductor housing of the phase conductor of the busbar section in the direction of the transverse axis aligned on a

Circular path are arranged whose center in the apex of the base branch and at least one, in particular two

Support branches of a Y-housing block is located.

A distribution of the individual phase conductor housing of the different phases of the busbar section on a

Circular path represents a compact embodiment of a transversely extending to the switchgear panel busbar Be. Preferably ^¬ within the circular path at the individual phase conductor housing of the phase conductor radially aligned Stut ^¬ zen for connection to corresponding Y-housing blocks

be positioned (in particular with their support branches). An arrangement of the circular path around a center, which in

Vertex of a base branch and at least one of Support branches of the Y-housing block is located, allows a symmetrical design of the busbar section.

Advantageously, it can further be provided that the Y-housing module on at least one of its branches with a

Ring flange is provided, which has a Verschraubungstei- lung of 22.5 ° or a multiple thereof.

For the integration of a Y-housing block into a switchgear panel, advantageously the use of

Ring flanges are provided. Ring flanges may in this case have to all branches of the Y-block housing similar Di ^¬ mensions. The annular flanges should have annular flange surfaces. Preferably, glands should be positioned on the annular flanges, which serve in the circulation of the annular flange symmetrically distributed a bracing a flange. The glands should be evenly distributed on a circular path. The screw connection should be 22.5 °. Thus, it is ensured that even with a rotation of a Y-housing ^¬ block about a cylinder axis of the base branch and a circular distribution of the individual phase conductor housing a busbar section can be done a correct screwing the ring flanges. At the same time, compliance with the positions of the individual axes within the switchgear panel is enforced by the 22.5 ° division. Needs ^¬ way axes can also be made of z. B. Vertical or horizontal, preferably by 22.5 ° or an integral multiple thereof.

A further advantageous embodiment may provide that the Y-housing module is bulged dome-like in the apex region of the branches. A dome-like bulge can be effected for example by ei ^¬ ne spherical shape of the Y-housing block in the ticket ^¬ telbereich of the individual branches. advantageously, For this purpose, the individual branches should be arranged in alignment in one plane, so that they are radially forbearing when using, for example, a spherical body for dome-like bulge in a diameter plane. In a first approximation, for example, a first and a second support branch as well as a base branch on an equator of the ball can extend distributed in a radiating manner around the circumference. The individual branches should in each case be designed substantially hollow-cylindrical, wherein the radial extension refers to the cylinder axes.

A further advantageous embodiment can provide that a first group of phase conductor housings are supported on Y housing modules and a second group of phase conductor housings are arranged cantilevered in the direction of the transverse axis on a common circular path, in each case offset by 45 ° relative to one another.

It can be provided that a group of phase conductor housings, in particular three phase conductor housings, are respectively positioned via Y housing modules. Such a first group may provide a positioning of the individual phase conductor housing distributed on a circular path. The circular path is defined with respect to the transverse axis of the switchgear genschaltfeldes, wherein the preferably hollow-cylindrical in Wesentli ^¬ chen phase conductors of the busbar housing nenabschnittes with their cylinder axes extending substantially parallel to the transverse axis. The arrangement of a second group of phase conductor housings can furthermore be provided on one and the same circular path, whereby these pass through the respective Y housing modules in particular at a distance, but are themselves also designed to run transversely to the switchgear panel. The phase conductors of the phase conductor housings, which are positioned at a distance from the Y-housings, do not protrude directly into the Y-housings. Such a use of a first and a second group, with only one group immediately above Y- Housing blocks is supported, for example, for the ^¬ design of a switchgear panel serve as a so-called dome panel. In such a Kuppelschalt ^¬ field, the phase conductors of the phase conductor housing of the first group and the phase conductors of the phase conductor housing of the second group via an electrical switching device, such as a circuit breaker, can be switched. Thus, the possibility exists, within a Schaltanlagenschaltfel ^¬ of a busbar section, which extends transversely to a switchgear panel, to interrupt. Thus, it is possible to divide the bus bar into a first portion and a second portion, wherein the first section several Schaltanlagenschaltfeider can be arranged, and more melschienenabschnittes Schaltanlagenschaltfeider may be at ^¬ arranged at the second section of the hunt. In this case, the first group of phase conductor housings is assigned to the first subsection, the second group of phase conductor housings is assigned to the second subsection, so that a longitudinal disconnection of the busbar is made possible via a switchgear panel designed in this way. In the area of the switchgear panel, it may be preferable to make the phase conductor / phase conductor housing jump on the circular path. In this case, the sections protrude from each other with different sense of direction, wherein phase conductor housing of the various sections of Sam ^¬ melschiene lie in divergent sectors of the circular path.

By adhering to a circularly offset by 45 ° arrangement of the individual phase conductor housing such a ges switches panel for busbar longitudinal separation can be inserted in alignment in a switchgear with a variety of the same ^¬ like Schaltanlagenschaltfeidern, so that a busbar longitudinal circuit is made possible. A further advantageous embodiment may provide that on the Y-housing block a grounding switch for grounding a is disposed within the Y-housing block phase conductor.

A Y-package may be configured such that in the interior of the Y-housing block located or projecting phase conductors are contacted, for example, permanently electrically conductive, so that the various phase ^¬ conductors, for example, within the base branch and at least within one, in particular both Support branches extend, node-point-like contact with each other. The phase conductors within a Y-block housing, which are assigned to a phase, always guide the moving ^¬ surface electric potential. The phase conductors can be acted upon within the Y-housing block, for example by means of a grounding switch with ground potential. The grounding ^¬ switch can be designed differently. In ^¬ example, a grounding switch can be centrally located at the apex of the support arms and the base branch, starting from this point, a movable contact piece of the earthing switch with a mating contact, which ground potential leads, can be contacted. Conversely vorgese ^¬ hen may be that a movable contact piece of a grounding switch ^¬ permanently carries ground potential, which is movably mounted in the region of the housing of the Y-block housing and, if necessary, to the phase conductor inside the Y-

Housing blocks can be moved. It can be seen ^¬ this is that only a grounding switch for grounding the phase conductors, particularly the phase conductor node is ^¬ sets is. However, it can also be provided that the phase conductors extending through the support branches can each be earthed via separate earthing switches. These separate earthing switches can be located inside the support branches, but it can also be provided that they are arranged, for example, on adjoining housing assemblies (eg, the phase conductor housing) of the switchgear panel. Furthermore, it can be provided that the Y-housing block is associated with an electrical switching device. This electrical ^¬ specific switching device can be, for example a release switch, which for example the running in the base branch of the Y-Gehäusebau- stone phase conductor can electrically contact with a running within one of the branches supporting the phase conductor. For example, the circuit breaker may optionally connect the phase conductor of the base branch to a phase conductor of the first support branch or of the second support branch. If necessary, the phase conductor of the base branch can also be connected to both phase conductors of the two support branches. In addition to the use of a single circuit breaker can also be provided that in each of the support branches, a separate circuit breaker is arranged, which connects each one located in the support branches phase conductor separable with the phase conductor of the base branch. The disconnectors Kgs ^¬ NEN thereby within the support branches are, but it may also be provided that the separating switch in adjacent to the support housing assembly branches (z. B. a phase conductor housing) are located.

When using two separate circuit breakers, the use of a single earthing or the use of multiple earthing switches may be provided, wherein the plurality of earthing switches, for example, the phase conductors in the support branches each ground separately, in particular after they are electrically isolated from a phase conductor of the base branch. For example, a circuit breaker can be used which switches a stitch from a phase conductor of the busbar section extending within a phase conductor housing into a Y housing module. A disconnect switch can be used to alternately connect a phase conductor of a base branch to one or the other phase conductor of a support branch. In addition to a switching function within the Y-block housing, the arrangement of a grounding switch to the Y-Gehäusebau ^¬ stone may further be provided. For example, it is possible to If necessary, the earth conductor of the phase conductor housing or other in the Y-housing module projecting phase conductor to apply ground potential. It can also be provided, for example, that the earthing switch is designed as part of a combined disconnecting earthing switch, so that in addition to an earth also a separation of electrically conductive phase conductors, which extend in the interior of the Y-housing block, is possible. A further advantageous embodiment may provide that a movable contact piece of the earthing switch in

Vertex area of the Y-housing ^block surrounded by the Y-housing ^¬ construction stone is movably mounted. The arrangement of a movable contact piece of a grounding ^¬ switch in the apex area of the Y-housing block made it ^¬ light, for example, a rotating contact, in particular ^¬ a knife contact to use, which is movable, for example, by 360 °. On the pivoting track of the movable contact piece, various stationary mounted counter contacts can be located at different positions, which in particular can come into contact with the movable contact piece in chronological succession. Thus, it is possible, for example, to permanently apply a ground contact to a mating contact piece, so that the movable contact piece, as well as the corresponding phase conductor connected to the contact piece in an electrically conductive manner, connect to ground potential. Furthermore, provided by a provided in the apex region of the Y-housing contact piece bearing the movable contact piece, for example, in a plurality of aligned Y-housing blocks a common, projecting into the individual Y-housing blocks or this durchset ^¬ zende shaft to be used as a drive element. Thus, it is possible to play at ^¬ to move the shaft drive device by a single check, wherein movements can be transmitted to the interior of Y-blocks to the housing ent ^¬ speaking moving contacts on the common shaft. A further advantageous embodiment may provide that a movable contact piece of the earthing switch is movably mounted on the Y-housing block.

By a movable positioning of the movable contact piece on the Y-housing block, the movable contact piece can be ^aufschlagt permanently in a simplified manner with ground potential be ^¬ . If necessary, the movable contact piece can then be moved toward a phase conductor in the interior of the Y-housing block, so that this phase conductor is subjected to ground potential. It can be particularly advantageous if at least a portion of the Y-housing block is made of electrically conductive material, which leads a Erdpo ^¬ potential. For example, it can be provided that the housing of the Y-housing block is made of a cast metal gefer ^¬ , which permanently leads ground potential. Entspre ^¬ accordingly can advertising made a simplified form a grounding current path via the housing of Y-housing module to.

Electric energy system to be used with a first phase, a second phase and a third phase for electrical energy transmission. The phase conductors of the three phases are arranged independently of each other electrically isolated, wherein in each of the three phases, a temporally and quantitatively different to the other phases current can be performed, which are fed for example by a three-phase AC voltage system.

The switchgear panel has a first phase 1, a second phase 2 and a third phase 3. All three phases are carried out in the switchgear panel with regard to their electric circuit of the same kind, wherein exempla ^¬ driven the construction of the first phase 1 is to be explained in more detail. The first phase 1 of the switchgear panel has a cable entry module 4. The cable entry module 4 has a substantially hollow cylindrical housing, wel ^¬ ches is frontally provided with a cable connection element. For example, this cable connection element can be designed as a Ka ^¬ belstecker, so that a cable 5 can be connected to phase 1 of the switchgear panel. Pre- lying the use of a single-conductor cable 5 is vorgese ^¬ hen. Inside the cable entry module 4, a phase ^¬ conductor is electrically isolated from the housing of the cable entry module 4 is held. A phase conductor serves to guide an electric current. The interior of the cable entry module 4, as well as other housing of Schaltanla ^¬ genschaltfeldes, is filled with an electrically insulating fluid, in particular an electrically insulating gas such as sulfur hexafluoride or nitrogen. The electrically isolie ^¬ Rende fluid is enclosed standing under an excess pressure in the interior of the individual housing. The housings hermetically enclose the electrically insulating fluid and prevent it from escaping. Sheath side is over a connection on the Cable insertion module 4 a separator housing 6 flanged. In the disconnector housing 6, a circuit breaker is arranged wel ^¬ cher allows electrical switching of the composite with the cable 5 ^¬ nen phase conductor.

A circuit breaker is capable of breaking rated currents or short-circuit currents several times safely. An electromechanical actuation of the breaker unit of the circuit breaker is made possible by means of a drive unit 8 arranged on the face side on the circuit breaker ^housing with interposition of an angular module.

A busbar section of the switchgear panel extends transversely to the sequence of phases 1, 2, 3 of the Schaltanla ^¬ genschaltfeldes. About the Y-housing block 9 is a coming from the interrupter unit phase conductor via a

Disconnector-earthing combination 12 optionally distributed to a phase conductor of the first phase conductor housing IIa of the busbar or a phase conductor of the second phase conductor housing IIb of the busbar section. Alternatively, a contacting of the coming of the breaker unit of the circuit breaker housing 7 phase conductor can be made with ground potential.

In addition, any arrangement of earthing switches can be provided so that any grounding of the individual phase conductors in base branch 13 and in the support branches 10a, 10b or the phase conductor of the phase conductor housing IIa, IIb can be made.

The use of a combined separator-earthing combination 12 shown in the figures is only to be understood as an example.

The busbar or the busbar section is made before ^¬ lying as a double busbar. The first and the second phase conductor housing IIa, IIb are each assigned to phase 1 and each surround a phase conductor of phase 1 of the double busbar. Optionally, the circuit breaker unit of phase 1 or of the cable 5 can be connected to one of the phase conductors of phase 1 of the double busbar of the busbar section via the disconnector-earthing combination 12.

Based on the side view of Figure 2, the structure of extending in the direction of the transverse axis busbar section is illustrated. The busbar section is presently designed as a so-called double busbar. Two parallel-running three-phase busbar strands are designed as a collective ^¬ rail section, each of the double busbars each having a phase conductor of the first phase 1, the second phase 2 and the third phase 3. The a ^¬ individual phase conductor housing are in the direction of Querach ^¬ se (perpendicular to the drawing plane of FIG. 2) arranged distributed on a circular path, wherein the first three-phase bus bar and the second three-phase busbar of the busbar portion of each of the Urzeigersinnes opposite aufein ^¬ other following the first phase 1, the second phase 2 and the third phase 3 has.
