The busbar encapsulation module (1, 2, 15 ', 16') extends substantially in a transverse direction, wherein the busbar encapsulation module (1, 2, 15 ', 16') is carried by a main encapsulation module (4, 4a, 9, 9a) extending substantially in a vertical axis direction.

Description

Encapsulation housing arrangement for a gas-insulated switchgear assembly

The invention relates to a switchgear having a busbar encapsulation module which extends substantially in a transverse direction for connecting a plurality of switchboards of the switchgear and is carried by a main encapsulation module which extends substantially in the direction of a vertical axis.

Such a switching device is known, for example, from international publication WO 2012/065630 Al. The switchgear is equipped with a busbar encapsulation module for connecting a plurality of switchboards of the switchgear. Here, the bus bar encapsulation module extends in the lateral direction. For supporting the busbar encapsulation module, it is provided to use a main encapsulation module which extends substantially in the direction of the vertical axis. In order to have a plurality of busbar encapsulating modules arranged in a stepped manner with respect to one another, different types of curved, substantially T-shaped housing assemblies are provided. Additionally, the T-shaped housing assembly is equipped with L-shaped curved appendages to effect deflection. This necessitates the use of differently shaped T-shaped housing assemblies in order to orient the busbar encapsulation modules relative to each other.

The object of the present invention is therefore to provide a switchgear assembly which allows high variability in the construction of the switchgear assembly with a reduced number of structurally simple modules or components.

The object is achieved according to the invention by a switchgear of the aforementioned type, in which provision is made for a branch to be arranged on the housing side on the main encapsulation module, the branch being oriented substantially perpendicular not only to the vertical axis of the main encapsulation module but also to the transverse direction, and for a busbar encapsulation module to be supported on the branch.

The switching device is used to establish or disconnect an on-state, in which a plurality of power distribution panels are connected or can be electrically connected to one another via at least one bus bar encapsulation module. The power distribution panels serve as an inlet and an outlet for the bus bar encapsulation module, so that different power distribution panels can be electrically connected to each other or electrically disconnected from each other via the bus bar encapsulation module. Preferably, the electrical distribution board may be arranged substantially transverse (or relative to the transverse) to the bus bar encapsulation module, depending on the type of marking. A typical switchgear panel of a switchgear assembly usually has a circuit breaker unit with a circuit breaker, wherein the circuit breaker is connected to a first connection side with a busbar encapsulation module and to a second connection side, for example with connecting lines, connecting cables, generators, etc. In order to achieve different switching states, it can be provided that a disconnection switch device and/or an earthing switch device is additionally arranged on the second connection side of the circuit breaker in order to be able to disconnect or to earth a connecting line or the like connected on the second connection side. Similarly, it can also be provided that a disconnection switch or an earthing switch is arranged on the first connection side of the circuit breaker in order to achieve electrical isolation or earthing of the connected busbar encapsulation module. At least one, in particular both, connection sides can be constructed from the main encapsulation module. The main encapsulation module is preferably arranged in/on the electrical panel. The main encapsulation module can be arranged (in particular supported) on the circuit breaker, in particular on an encapsulation housing of the circuit breaker.

For monitoring the electrical panel, measuring transformers can additionally be arranged in the electrical panel. The measuring transformer may be, for example, a current transformer or a voltage transformer. Preferably, a voltage transformer should be arranged on the second connection side of the circuit breaker, so that the potential of the connecting line, the connected voltage transformer, etc. can be measured. Furthermore, the current transformer can be arranged not only on the first connection side but also on the second connection side of the circuit breaker. Preferably, the measuring transformers can be integrated on/in a measuring transformer encapsulation of the switchboard for connecting the power switch to the busbar encapsulation module or to the connecting wires or the like. The measuring transformer encapsulation has an encapsulation here. The measurement transformer capsule may be part of a main capsule module.

The electrical panel has at least one, in particular a plurality of, encapsulation housings. Respectively, may be mechanically coupled to each other.

The encapsulation housing encloses internally a phase conductor for conducting the current. The phase conductors may be spaced apart and electrically insulated by the insulating arrangement of the package housing. The encapsulation housing can enclose the phase conductor in a sealed manner, so that the interior of the encapsulation housing can be filled with an electrically insulating medium.

The main encapsulation module serves as a support column to hold the bus bar modules at intervals. For a main encapsulation module extending substantially along a vertical axis, a substantially cylindrical structure, in particular an encapsulation housing, can advantageously be used. For example, a part of the main package module may be formed by a current transformer or a measuring transformer package case. The main encapsulation module can extend substantially tubular in the vertical direction, wherein the branch for supporting the busbar module can be arranged on the housing side on the main encapsulation module. The main encapsulation module can have a plurality of encapsulation housings, in particular flanged to one another. The orientation of the branch perpendicular to the vertical axis and perpendicular to the horizontal axis here refers to the direction of passage of the phase conductors arranged inside the encapsulation housing or the branch. Thus, the phase conductors of the busbar encapsulation module extend substantially in the transverse direction, whereas the portions of the phase conductors located in the main encapsulation module extend substantially in the vertical axis. Accordingly, the orientation of the legs of the main encapsulation module on the housing side perpendicular to the transverse direction and substantially perpendicular to the vertical axis refers to the course of the phase conductors in the legs. This position may correspond, for example, to the flange axis of the flange or flange stub forming the branch.

In the construction of a switchgear having flanges such as threaded flanges, welding flanges, clamping flanges, etc., the package housings have flanges so as to be connectable to each other. The encapsulation module has at least one encapsulation housing. Thus, for example, in the case of welded flanges or threaded flanges, the flange plane is oriented substantially transversely, in particular substantially perpendicularly, to the flange axis. The phase conductor passing through the flange extends substantially in the direction of the flange axis.

Furthermore, it is also possible to project one or more branches from the main encapsulation module with the position of the housing side of the branches in order to support the busbar encapsulation module. The branch can be embodied, for example, in the form of a flange or a flange. Preferably, two oppositely oriented and in this case aligned branches can also be arranged on the main encapsulation module, so that for example a first and a second busbar encapsulation module on both sides (in particular on the housing side) of the main encapsulation module can be supported. The area of the front face (with respect to the vertical axis) of the main encapsulation module can be used for arranging other components, such as grounding switches, measuring transformers, etc. With respect to the complex curved modules known from the prior art, at least equivalent variability with respect to the structure of the switchgear can now be ensured with relatively simple modules/assemblies. If necessary, even the same components can be used, whereby the logistics costs for constructing the switchgear can be reduced.

A further advantageous embodiment can provide that the branch is formed by a cross-member of the main encapsulation module.

The cross assembly is an assembly having an enclosure housing. The cross-member arrangement here generally has cross-arranged branches, in particular flange pieces, which are preferably located in one plane and are oriented perpendicular to one another, wherein two flanges facing one another are each preferably oriented in alignment. The first branch and the second branch can be formed on the main encapsulation module on the housing side, in particular aligned opposite to each other, by means of the cross-member. Furthermore, additional connection possibilities can be provided on the front side in alignment with the vertical axis of the main encapsulation module, so that, for example, earthing switches, measuring transformers, etc. are arranged there and in particular flange-connected there.

It can furthermore be advantageously provided that the busbar encapsulation module is supported on the cross assembly.

The crossover assembly has a plurality of leg and flange connections so that bus bar encapsulation modules supported on the crossover assembly can be variably arranged. The cross-bar assembly here acts as part of the main package module. The busbar encapsulation module may be at least partially supported on the crossover assembly.

It can furthermore be advantageously provided that the busbar encapsulation module is supported indirectly with the interposition of a further crossover component on a branch of the main encapsulation module.

In addition to the direct flange connection of the busbar encapsulation module to the branch of the main encapsulation module, it can also be provided that the support of the busbar encapsulation module is effected indirectly by the intermediate arrangement of at least one further crossover component. The position of the busbar encapsulation module can be varied by arranging further cross-members directly or indirectly on the branches. Thus, for example, the busbar encapsulation modules can be supported in alignment with the legs by using additional cross-members. However, it can also be provided that the busbar encapsulation module is arranged in a laterally offset orientation relative to the branch using a further crossover component. In particular, in the lateral offset, the busbar encapsulation module can be inserted into the unused wedge-shaped space of the switchgear.

Furthermore, by using further crossing assemblies, it is possible to deflect the busbar encapsulation modules in addition to laterally offsetting their position, for example by the branches of the crossing assembly of the main encapsulation module and the branches of the further crossing assembly extending, for example, in different planes.

Furthermore, the space provided inside the cross-bar assembly can be used to accommodate electrical switching apparatus by using additional cross-bars. This is advantageous in particular in the case of passive busbar encapsulation modules, in which the busbar encapsulation module or its encapsulation housing itself has no switching device.

It can furthermore be advantageously provided that the further cross assemblies form sections of the busbar encapsulation module.

The further crossing assembly itself may form a section of the busbar encapsulation module, independently of the position of the further crossing assembly. That is, the crossover assembly forms a portion of the package housing of the busbar package module. The further crossbar assembly is part of the busbar circuit (sammelschinenzuges) of the busbar encapsulation module, whereas, in the case of supporting the busbar encapsulation module by means of an intermediate connection of a further crossbar assembly, it only performs the function of lengthening/displacing the branches of the main encapsulation module.

The concentration of additional crossover components in the busbar encapsulation module makes it possible to dispense with the use of crossover components which are used only for rerouting and extending the branch to the busbar encapsulation module. Rather, the connection of the busbar encapsulation module to the branches of the main encapsulation module can be realized here by means of the same crossover component. The further crossover assembly is part of a busbar encapsulation module. In the case of a switchgear arrangement in a packaging assembly (i.e. in a packaging housing of a busbar packaging module), a so-called active busbar packaging module is formed.

In a further advantageous embodiment, the cross-like projecting legs of the cross modules of the main encapsulation module and the cross-like projecting legs of the further cross modules are each arranged substantially in a plane, and the busbar encapsulation module is arranged on the further cross modules.

The cross-wise erected legs (e.g., flanges, flanged nipples) of the crossover assembly are used to connect the crossover assembly substantially along axes that substantially intersect each other. The guiding, turning and connecting of the busbar encapsulation module to the main encapsulation module can be realized in one plane if the legs of the crossing assembly of the main encapsulation module and the legs of the further crossing assembly are substantially in one plane. This is particularly advantageous when the space is narrow. In particular, when using a common (multi-phase/multi-stage) encapsulated busbar encapsulation module, in which a plurality of phase conductors are arranged, the main encapsulation modules of the same construction for the phases are each continuously aligned substantially uniformly with the transverse direction. In a simple manner, similar connection possibilities can therefore be established in the switchboard in order to enable a transition from a multi-phase encapsulated busbar encapsulation module to a single-phase encapsulated main encapsulation module/modules. Accordingly, similar modules oriented in alignment with one another may be used.

A further advantageous embodiment can provide that the crosswise lying (or lying) branches of the crossing assembly of the main encapsulation module and the crosswise lying branches of the further crossing assembly, which are sections of the busbar encapsulation module, each extend in a plane, wherein the two planes intersect one another, in particular are perpendicular to one another.

The branches of the crossing assembly each extend in one plane, it being possible to couple the crossing assemblies to each other and to integrate further crossing assemblies as sections of the busbar encapsulation module in positions of the planes that are substantially perpendicular to each other by using a plurality of crossing assemblies, wherein two planes of the plurality of crossing assemblies intersect each other. The legs of the further crossover assembly can thus form part of the encapsulation housing of the busbar encapsulation module, wherein the flange axes thereof can be oriented in particular in the transverse direction, so that the internally arranged phase conductors pass the crossover assembly in the transverse direction. Such a position of the crossing assemblies relative to each other provides particular advantages when the busbar encapsulation module has a single-phase (unipolar) encapsulation of the phase conductors, so that a connection via further crossing assemblies to the main encapsulation module can be realized starting from one phase conductor inside the busbar encapsulation module. In addition, the spacing of the plurality of bus bar encapsulation modules, each insulated by a single phase, arranged along the vertical axis direction may also be implemented. The main encapsulation modules arranged one behind the other in the transverse direction can each support different busbar encapsulation modules in different planes, the busbar encapsulation modules preferably extending substantially parallel to one another. The branches for supporting the encapsulation modules can be arranged offset to one another in the direction of the vertical axis on different main encapsulation modules.

In a further advantageous embodiment, the cross assembly can have a plurality of flanged nipples, at least one of which has a different nipple length.

The cross assembly has an encapsulation housing with a plurality of flange connections via which the cross assembly can be flange-connected to further flange connections. The flanged connections are arranged substantially radially to one another, wherein preferably the positions of the individual flanged connections that are perpendicular to one another are to be defined. Preferably, the flanged nipples of the crossing assembly lie in one plane, such that preferably at least one pair, in particular a plurality of pairs, in particular two pairs, of flanged nipples are arranged opposite each other in alignment and the respective alignment axes preferably cross each other. Preferably, one flange piece has a different flange length than the other flange pieces, so that a symmetrical cross-member along the flange axis is preferably formed, but only with respect to the flange axis running through the pieces having different piece lengths.

In a further advantageous embodiment, the cross assembly can have four flange connections arranged crosswise, wherein one flange connection has a different connection length relative to the other flange connections.

The difference in the length of the flange pipe of one of the four flange pipes, in particular in relation to the length of the remaining, in particular equally long, flange pipe, has the following advantages: the base flange is formed by flange nipples of different nipple lengths, from which three further flange nipples extend in a similar manner. Furthermore, by using such a cross assembly which is configured asymmetrically with respect to one flange axis of the flanged joint and symmetrically with respect to the other flange axis of the flanged joint, different types of compensation or height variations can be implemented by selecting and using flanged joints of different joint lengths.

A further advantageous embodiment can provide that the cross-member has a similar housing contour.

The number of different package housings can be reduced by using similar cross-members having similar housing profiles. In addition, in particular in the case of a cross assembly using nipples having different nipple lengths, different positions of the individual flanged nipples of different nipple lengths in the case of a flanged connection of two cross assemblies are provided relative to one another. A similar housing profile is basically associated with the interface on the cross assembly defined by the flanged connection. That is, even if there are differences in the design of the crossover assembly itself, the location of the interface formed by the flanged pipe should be maintained in the case of similar housing profiles. Thus, a similar shell profile can be maintained even if the design of the crossing assemblies differ from each other in detail, whereby the crossing assemblies can be modularly interchanged with each other and a modular system can be formed.

A further advantageous embodiment may provide that at least one of the modules (or the encapsulation housing) is filled with an electrically insulating fluid.

By filling at least one, in particular a plurality of, modules/encapsulation modules of the switchgear with an electrically insulating fluid, the electrical insulation of the phase conductors can be protected inside the modules, for example phase conductor sections in a busbar encapsulation module, phase conductor sections in a main encapsulation module or phase conductor sections inside a cross assembly. In the case of a fluid-tight design of the individual modules or assemblies, evaporation of the fluid can be prevented, and if necessary, the modules or their encapsulation can be designed as a pressure vessel, so that the fluid can also be filled under pressure. Suitable fluids may be, for example, gases or liquids, wherein a fluid having a fluorine component has proven to be particularly advantageous here, since it has good arc extinguishing properties in addition to good insulating properties, for example when an arc caused by a switching operation or a fault is interrupted. As fluorine-containing fluid, for example, sulfur hexafluoride, fluoronitrile or fluoroketone or other fluorine-containing organic compounds can be used. Alternative electrically insulating fluids, for example based on nitrogen or carbon dioxide or clean air, may be used in addition to the fluorine-containing fluid to ensure sufficient insulating strength.

A further advantageous embodiment can provide that the contact pitch of the switching device is arranged within the cross-member.

The crossover assembly has in its interior, in addition to the arrangement of the phase conductors and the electrical insulation, the contact spacing of the switchgear. Such a switching device is characterized in that, for example, the relatively movable contact pieces can open or close the contact pitch. Such a switching device can, for example, interrupt or establish a phase conductor. Furthermore, it is also possible to provide switching devices, for example for safety reasons, in which a predetermined potential is applied to the phase conductor. A plurality of switching devices may also be arranged on/in the crossing assembly.

A further advantageous embodiment can provide that the switching device is a circuit breaker.

A circuit breaker is a switching device for opening or closing a phase conductor path. The circuit breaker is designed to be switched on and off in the absence of current. Therefore, the disconnection switch cannot switch the operating current. Although switched on and off without current, a discharge phenomenon can also occur on a switching device in the form of a circuit breaker. For example, by capacitive charging, the discharge current can also flow through the circuit breaker in the currentless state, as a result of which a switching arc can form in the event of an opening distance. Quenching of the switching arc can be supported on such a circuit breaker by means of an electrically insulating fluid which can be arranged inside the crossover assembly.

It can furthermore be advantageously provided that the switching device is an earthing switch.

The ground switch is a switching device for applying a ground potential as needed to a phase conductor arranged inside the module in an electrically insulated manner. This is necessary, for example, if a safety circuit is to be implemented and in any case an unintentional undervoltage connection of the phase conductor is to be prevented. The ground switch is therefore equipped with a contact pitch that makes it possible to connect the phase conductor to ground potential. In this case, different embodiments of the earthing switch can be provided, for example, the so-called operating ground can be equipped with relatively slow-running, relatively movable contacts, while the faster contacts are relatively fast, which, for example, in the event of an identification of a fault situation or in the event of an imminent fault situation, leads to earthing of the phase conductor.

fig. 16 shows an alternative design of a cross assembly with a grounding switch, including a disconnecting switch with a flange connection that is possible for grounding.

Fig. 1 shows an electrical panel with a first passive busbar encapsulation module 1 and a second passive busbar encapsulation module 2. The passive

busbar encapsulation modules

1, 2 each have a tubular encapsulation housing, wherein the tube axis of the encapsulation housing extends substantially parallel to the transverse direction. The tube axes of the housing shells of the first and second passive

busbar encapsulation modules

1, 2 are substantially perpendicular to the plane of the drawing of fig. 1. In order to mount the two

busbar encapsulation modules

1, 2, a first main encapsulation module 4 is flanged onto the encapsulation housing of the circuit breaker 3. For this purpose, the encapsulation of the circuit breaker 3 is equipped with a corresponding flange on which the first main encapsulation module 4 is mounted. The flange of the housing of the circuit breaker 3 is oriented in such a way that the first substantially tubular main housing module 4 is oriented along a vertical axis. Accordingly, the lateral and vertical axes are substantially perpendicular to each other, with the vertical axis lying in the plane of the illustration of fig. 1. The first main encapsulation module 4 has a first current transformer 5 for converting current. The cross member 6 is connected to the housing 3 of the circuit breaker by an intermediate connection of a first current transformer 5. The cross assembly 6 has first, second and third and fourth

flanged nipples

7a, 7b, 7c, 7 d. In this case, the first flange 7a is provided with a greater pipe length than the remaining

flanges

7b, 7c, 7 d. The

flanged nipples

7a, 7b, 7c, 7d are each oriented at right angles to one another and extend (with their flange axes) substantially in a plane (here the plane of the drawing) such that the two

flanged nipples

7a, 7c or 7b, 7d are each oriented in axial alignment with one another. The

flanged connections

7a, 7b, 7c, 7d each have a circular cross section. A housing-side branch is formed on the first main encapsulation module 4 by means of two flanged nipples 7b, 7c, said branch having aligned flange axes which are substantially perpendicular not only to the vertical axis of the first main encapsulation module 4 but also to the transverse direction of the passive

busbar encapsulation module

1, 2. The flanged stub 7a with the greater stub length is aligned with the vertical axis of the first main encapsulation module 4, oriented/arranged away from the first current transformer 5.

Further cross members

8a, 8b are flanged to the branches, respectively. The

further cross members

8a, 8b are substantially designed as cross members 6 similar in construction to the first main encapsulation module 4, wherein at least their housing contours coincide. In this case, flanged connections 7a with an extended connection length are used in the

further crossover assemblies

8a, 8b in order to be flanged respectively with the

flanged connections

7b, 7d of the crossover assembly 6 in the first main encapsulation module 4, which are used as branches. The remaining flange connections of the

further crossover assemblies

8a, 8b can thus be used in order to carry the encapsulation housings of the first and second passive

busbar encapsulation modules

1, 2. For this purpose, the housing shells of the first and second passive

busbar housing modules

1, 2 are designed with corresponding shell-side flanges in order to establish a connection with the

further cross members

8a, 8 b.

A further flange is arranged on the housing of the first circuit breaker 3, to which a second main housing module 9 is connected. The second main encapsulation module 9 is here designed substantially similar in structure to the first main encapsulation module 4 and substantially parallel thereto. That is to say, a second current transformer 10 is connected to the encapsulation of the circuit breaker 3, to which the crossover assembly 6 is also flanged. The position is selected analogously to the cross-member on the first main encapsulation module 4 in such a way that the elongated flanged pipe 7a is oriented in alignment with the vertical axis, facing away from the second current transformer 10, relative to the similarly constructed

flanged pipes

7b, 7c, 7 d. Accordingly, the housing-side branch on the second main encapsulation module 9 is aligned with the housing-side branch of the first main encapsulation module 4. The flange of the cross-member 6 of the second main encapsulation module 9 facing the first main encapsulation module 4 is closed by means of an imperforate cover. On the oppositely aligned branches of the crossover assembly 6, an inverted crossover assembly 11 is arranged, wherein the inverted crossover assembly 11 is flanged to the branches of the second main encapsulation module 9 by means of a flange stub having an increased stub length relative to the remaining flange stubs of the inverted crossover assembly 11. By means of the increased length of the connecting tube, a space can be formed in which electrical switching devices, such as circuit breakers and/or grounding switches, can be installed. In alignment with the housing-side branch of the second main encapsulation module 9, the terminal module 12 is flanged to the inverted cross member 11. A voltage transformer 13, which reflects the voltage of the cable 14 connected by means of the terminal module 12, is also flanged to the terminal module 12.

In fig. 1, the course of the current-carrying phase conductors inside the encapsulation housing can be seen in addition to the individual modules or components which can be part of the modules. The first and second passive

busbar encapsulation modules

1, 2 have three phase conductors in their interior, respectively, so that the first and second passive busbar encapsulation modules are multiphase (multi-stage) encapsulated busbar encapsulation modules, respectively. Alternatively, it can also be provided that the first and/or second passive busbar encapsulation module is embodied encapsulated as a unipolar (single-phase) variant, so that only one phase conductor for conducting the current is arranged in each case inside the encapsulation housing.

In the present case, starting from the multi-stage insulation of the first and second

busbar encapsulation modules

1, 2, a single-pole insulation of the respective phase conductor is provided within the

further crossover assembly

8a, 8b for connection to the first main encapsulation module 4 and additionally via the circuit breaker 3 and the second connection side. Starting from one of the phase conductors of the first and second passive

busbar encapsulation modules

1, 2, respectively, the isolation or separation of the individual phase conductors can be achieved via a disconnection switch in the respective

other crossover component

8a, 8 b. Furthermore, a branching of the phase conductors is provided in the crossover component 6 of the first main encapsulation module 4, so that the phase conductors of the first and second

busbar encapsulation modules

1, 2 can be brought into electrical contact with the first connection side of the circuit breaker 3 via a further run in the first current transformer 5. Furthermore, within the crossover assembly 6, the phase conductors of the first main encapsulation module 4 can also be interrupted by means of a disconnection switching device, so that the branching of the phase conductors of the first and second passive

busbar encapsulation modules

1, 2 can be interrupted. Furthermore, the phase conductor sections separated in the crossover assembly 6 by the disconnection switch can be grounded by means of a grounding switch.

The second current transformer 10 has a phase conductor in its interior, which is connected to the second connection side of the circuit breaker 3 in the encapsulation. The connection or disconnection of the electrically conductive connection between the phase conductor sections guided in the first or second

current transformer

5, 10 or in the first or second main encapsulation module 4, 9 can thus be effected by the circuit breaker unit of the circuit breaker 3 in the encapsulation housing. In the cross-member 6 of the second main encapsulation module 9, a grounding switch is provided in the course of the phase conductor in the direction of the terminal module 12. In addition, a disconnection switch is provided in the crossover assembly 11, by means of which electrical isolation of the phase conductors routed in the terminal module 12 can be achieved. Furthermore, an earthing switch is arranged on the inverted crossover component 11, whereby the phase conductors guided in the terminal module 12 can be earthed. The connection of the phase conductors in the switchgear to the phase conductors of the cable 14 can be effected via the junction module 12.

Fig. 2 shows a perspective view of the electrical panel known from fig. 1. It is clearly shown here that the three phase lines (conductors) arranged in common insulation in order to connect the first and second passive

busbar encapsulation modules

1, 2 need to be implemented correspondingly three times as much as the components and parts shown in the side view in fig. 1. The axially aligned arrangement of the encapsulation housing is particularly clearly shown, and the axially aligned arrangement of the main encapsulation module 4, 9 and the circuit breaker 3 is particularly clearly shown in the transverse direction of the power distribution board. In addition to the multiphase-insulated

busbar encapsulation modules

1, 2, the other modules/components of the switchboard are embodied as single-phase-insulated.

Fig. 3 and 4 show a second variant of the electrical panel with a first and a second active

busbar encapsulation module

15, 15 ', 15 ", 16', 16". With regard to the construction of the second main packaging module 9a, including the flipped cross assembly 11 and the patching modules 12, the voltage transformers 13 and the cables 14 connected thereto, see the implementation of fig. 1 and 2. Furthermore, the circuit breaker 3 in the encapsulation has the same structure and function as the circuit breaker 3 known from fig. 1 and 2.

Only the structure of the first main packaging module 4a, including the bus

bar packaging modules

15, 15 ', 15 ", 16', 16" supported therein, is changed. The first current transformer 5, which can be seen in fig. 3, is aligned in the lateral direction in a triple configuration, so that three encapsulated phase conductors, which are electrically insulated from one another, can be monitored. (see the perspective view of fig. 4). The extension of the first main encapsulation module 4a in the vertical axis direction is the same for all the first current transformers 5. On a first current transformer 5 of the first main encapsulation module 4a facing the viewer, a crossover assembly 6 is flanged analogously to fig. 1 and 2. It is also provided that the cross-member 6 is oriented in such a way that the cross-erected flanged connections are arranged in a plane and that this plane is oriented substantially perpendicular to the transverse direction. Correspondingly, a branch is arranged on the housing side on the first main encapsulation module 4a of the switchboard according to fig. 3, on which also the encapsulation housings of the first active

busbar encapsulation module

15, 15 ', 15 "and the second active

busbar encapsulation module

16, 16', 16" are flange-connected. The encapsulation housing is formed in part by

further cross-members

8a, 8a ', 8a ", 8 b', 8 b" connected to the branches. In contrast to the embodiment of fig. 1 and 2, it is provided here that the flange connections of the connected

further crossover components

8a, 8a ', 8a ", 8 b', 8 b", each extending in a plane, are oriented in such a way that they are perpendicular to the plane of the flange connections of the crossover components 6 in the first main encapsulation module 4a (the lying

further crossover components

8a, 8a ', 8a ", 8 b', 8 b"). Thus, the

further crossing assemblies

8a, 8a ', 8a ", 8 b', 8 b" of the first and second active

busbar encapsulation modules

15, 15 ', 15 ", 16', 16" are traversed in the transverse direction by the phase conductors constituting the busbars. In order to flange the

further crossover assemblies

8a, 8a ', 8a ", 8 b', 8 b" of the

busbar encapsulation modules

15, 15 ', 15 ", 16', 16" to the branches of the first main encapsulation module 4a, in each case a flange stub is used, which has an increased stub length in relation to the other remaining (laterally penetrated by the phase conductors) flange stubs. The phase conductors of the busbars are surrounded by and run through further

flanged cross members

8a, 8a ', 8 b'. Furthermore, a disconnection switch can be arranged in the

further crossing assemblies

8a, 8a ', 8a ", 8 b', 8 b", so that switching can also take place inside the (gas) space in which the phase conductors of the busbars are arranged. The

busbar encapsulation modules

15, 15 ', 15 ", 16', 16" that can be switched in the space of the phase conductors of the busbar are referred to as active

busbar encapsulation modules

15, 15 ', 15 ", 16', 16".

In the embodiment of the switchboard according to fig. 1 and 2, the one encapsulating housing accommodating the phase conductors of the bus bars is free of switching devices, wherein further cross-members 8a, 8b (connected in between) are required for arranging the switching devices. In the embodiment of the switchboard with active

busbar encapsulation modules

15, 15 ', 15 ", 16', 16", the

further crossing assemblies

8a, 8a ', 8a ", 8 b', 8 b" are themselves part of the encapsulation housing of the

busbar encapsulation modules

15, 15 ', 15 ", 16', 16", as shown in fig. 3 and 4.

In order to be able to arrange different encapsulation housings of the single-phase insulated

busbar encapsulation modules

15, 15 ', 15 ", 16', 16", the individual main encapsulation modules 4a facing away from the observer are arranged stepwise in their height. This is achieved, for example, by interposing a spacer encapsulation housing between the respective first current transformer 5 and the

cross assemblies

6, 6', 6 ″ supported thereby, whereby a parallel displacement of the respective branches on the respective first main encapsulation module 4a is achieved in the vertical axis direction (see fig. 4). Accordingly, the enclosure housings of the single-phase enclosed

busbar enclosure modules

15, 15 ', 15 ", 16', 16" may be axially spaced along the vertical axis. Alternatively, bus

bar encapsulation modules

15, 15 ', 15 ", 16', 16" using polyphase insulation can also be provided.

Fig. 5, 6, 7, 8, 9, 12, 11 and 12 show variants of the electrical panel known from fig. 1 and 2, respectively. In this case, the first and second passive

busbar encapsulation modules

1, 2 are each flanged differently to the cross member 6 of the first main encapsulation module 4, so that, in addition to the suspended arrangement of the first and second passive

busbar encapsulation modules

1, 2 shown in fig. 1, a supported arrangement of the first and second passive busbar encapsulation modules according to fig. 5 is also possible. Furthermore, fig. 6, 7, 8, 9, 12, 11 and 12 show combinations of

busbar encapsulation modules

1, 2 arranged in different planes, respectively, wherein these combinations are arranged variably by differently flange-connecting

further cross assemblies

8a, 8b via the cross assembly 6 of the first main encapsulation module 4, respectively.

Fig. 5, 6, 7, 8, 9, 12, 11 and 12 clearly show variants using similar cross assemblies, wherein different types of arrangements of the

busbar encapsulation modules

1, 2 can be realized. Different types of electrical panels can thus be built as desired.

Fig. 13 clearly shows the arrangement of the flat crossing assembly of the individual phase conductors of the first or second active

busbar encapsulation module

15, 16, which is flanged onto the crossing assembly 6. For better identification, an insulation is schematically shown, which arranges the phase conductor inside the encapsulation housing and is insulatively spaced with respect to the encapsulation module. The

further crossover component

8a, 8b lying flat is here part of the encapsulation housing of the first or second active

busbar encapsulation module

15, 16.

The arrangement of the additional grounding switch has been removed in fig. 13.

Fig. 14 shows an embodiment of a crossover assembly 6, which is located on the first main encapsulation module 4 (see fig. 5), wherein in the variant according to fig. 14 only one busbar encapsulation module 1 is connected to the branch by an intermediate connection further crossover assembly 8 a. The separation function is achieved by means of a cut-out switch which is itself located in the cross-over assembly 8 a.

Fig. 15 shows a possible arrangement of the crossover assembly 6 with the grounding switch. Via the housing-side branch carried by the first main encapsulation module 4, passive or active busbar encapsulation modules can be supported as required, wherein the grounding of the internally arranged phase conductors can be effected via grounding switches in the crossover assembly 6.

Fig. 16 shows a detail of the second main packaging module 9 as known from fig. 1, 2, 3 and 4. A cross member 6 is attached to the second current transformer 10 of the second main encapsulation module 9, by means of which cross member 6 the inverted cross member 11 is flanged at the housing-side connection of the second main encapsulation module 9. In the cross member, a grounding switch is arranged, whereby grounding of the phase conductors located inside the cross member 6 can be achieved. In the inverted cross member 11, a disconnection switch is arranged, with which the phase conductors connected to the phase conductors of the cable 14 via the connected terminal module 12 can be disconnected. The earthing switch is arranged on the flange-connected earthing switch housing 20, thereby providing additional space to allow relative movement of the earthing switch's earthing contacts inside the flipped cross-member 11.

The cross assemblies shown in the figures each have a flanged connection to a further flanged connection, wherein a fluid-tight connection of the respective cross assembly is thereby provided. In each variant, the flange connections not provided for the flange connection are closed with corresponding blank covers, so that a fluid-tight connection of the cross-members is provided, and the interior of each cross-member can be filled with an electrically insulating fluid. If necessary, the respective encapsulation housing of the assembly or module can be designed as a pressure vessel, so that the interior can be filled under pressure with an electrically insulating fluid, preferably a gas.

In order to seal the encapsulation housing, a fluid-tight barrier, for example in the form of an insulating arrangement, can be arranged in particular in the region of the flange.
