Control panel

The invention relates to a panel having a Sam rail portion and a first interrupter unit as a second interrupter unit.

A switch panel is known for example from the published patent application DE 196 06 213 Al. The local panel has a first and a second interrupter unit whose hous se are connected in a modular manner. On the one hand, such an arrangement permits high variability in construction. On the other hand, this requires a large number of specific modules. However, such a high variability is not required for all purposes, so that cost savings through a simplified structure are possible here.

Thus, it is an object of the invention to provide a kostengüns term embodiment of a panel, which offers a sufficient possibility of variation.

According to the invention the object is achieved in a switching panel of the type mentioned in that the busbar nenabschnitt extends along a transverse axis and the first and the second interrupter unit along a Tie fenachse aligned one behind the other, where at the depth axis, the transverse axis in the direction of a in we substantial vertical projection axis seen cuts.

For example, a button is a subunit of a

Electrical power transmission device. An electric power transmission device serves to transmit electrical energy. For this purpose, the electric power transmission device has at least one switching field, which cut a bus bar and has a first and a second breaker unit. A busbar section serves one Conducting an electrical current, wherein one or more phase conductors of the busbar section are to be electrically insulated accordingly. The running in the direction of a transverse axis busbar section can serve a connec tion of several panels. As a result, by means of the busbar sections of a plurality of cubicles, a transfer of electrical energy between sections connected via the bus bar sections is possible. A busbar nenabschnitt in this case has at least one, in particular several re electrically insulated (s), phase conductors. The longitudinal axis of a phase conductor runs essentially in the direction of the transverse axis. About stubs of the busbar section is connected to the first and the second interrupter unit. In this case, the first and the second Unterbre can be provided to chereinheit with one and the same Pha senleiter the busbar section contacted to who. However, it may also be provided that the first and the second interrupter unit with different Phasenlei are to contact the busbar section.

A depth axis extends substantially perpendicular to the transverse axis, in the direction of the busbars section is arranged extending. In the direction of the Querach se interfaces are provided at least at one end, in particular at both ends of the busbar section to make a contact of the busbar section of the switching field with a busbar section of an adjacent to an ordered panel. Adjacent panels can be consecutive net angeord in the direction of the transverse axis. In the direction of the depth axis, the two sub-breaker units are arranged in alignment one behind the other, so that in the line of sight of the depth axis, the breaker units overlap each other at least partially. Additionally or alternatively, an aligned alignment of sub-breaker units may be provided in the direction of the projection axis. Between the depth axis and the transverse axis in the direction of a substantially perpendicular projection axis seen results in an intersection between the depth axis and transverse axis. For example, it can be provided that the He extension of the busbar section in the direction of the transverse axis is greater than its extension in the direction of the depth axis (and vice versa).

The breaker units can be designed for different functions. For example, it may be a subcarrier unit of a grounding switch, a quick-change switch, a circuit breaker, a circuit breaker, a circuit breaker, etc. act. An interrupter unit is characterized in that it can cause a change in an impedance in a course of an electrical phase conductor. For example, this can be done by relatively movable to each other switching contact pieces.

In order to make an electrical insulation of the busbar section and / or a breaker unit or generally a Pha senleiters, a housing may have a fluid receiving space. In this case, the housing may be formed as a fluiddich tes encapsulating to include in its interior a special atmosphere can. To generate the special atmosphere, fluids can be used, which are preferably in gaseous form. Particularly suitable as fluids are fluorine-containing substances, such as sulfur hexafluoride, fluoronitrile, fluoroketone, and other electronegative substances, such as nitrogen, C0 ₂ , insulating oils, insulating esters, etc. Preferably, the housing may be formed as a pressure vessel, so that the fluid disposed in the interior under pressure can be set. Within the fluid receiving space may be arranged phase conductors which are surrounded by the fluid and are electrically insulated by this. A wall of a Kapselungsgehäuses can be electrically isolated penetrated by a phase conductor, so that the housing outside the Kapse an electrical contacting of the same is made light. For example, this may be provided at interfaces of the busbar section, for example several busbar sections of several panels mitei each other to connect. It can also be provided to delimit several fluid receiving spaces from one another within a cubicle.

The arrangement of the busbar section and the sub-breaker units can be provided such that in the direction of the projection axis of the busbar section to at least one of the interrupter units covered or the busbar section is covered by one of the interrupter units. However, it may also be provided that a spacing between the busbar section and Unterbre is provided chereinheiten, so that a mutual cover over each other does not occur. For example, the transverse axis and the depth axis cross-like duri fen, wherein depending on the arrangement of the busbars section in the direction of the projection axis seen the Sam melschienenabschnitt before the breaker units or above or below the breaker units or in front of the lower breaker units.

Furthermore, it can be advantageously provided that in the direction of the projection axis between the depth axis and transverse axis an angle of about 45 ° to about 135 °, in particular of about 90 °, is included.

Preferably, should be provided between the depth axis and transverse axis from Rich direction of the projection axis seen a rectangular Anord statement. As a result, the construc tion and the construction of a compact switchgear, which has a plurality of interconnected in the direction of the transverse axis panels easier. Accordingly, Cartesian coordinates can be used. However, it can also be provided that an angle between the depth axis and the transverse axis is closed, which is about 45 ° to about 135 °. For example, a pivoting of a panel to the transverse axis can be made. This is an arrangement of a Switch panel allows, which undergoes a shortening in the direction of the depth axis, wherein by pivoting a staggering of the panel in the direction of the transverse axis he follows.

A further advantageous embodiment can provide that in the direction of the projection axis, the breaker units are arranged approximately at the same height.

By aligned alignment of the interrupter units they can cover each other at least partially, in particular completely, in the direction of the depth axis, so that one interrupter unit is covered / covered by an offset unit from another sub-unit. In particular, in construction same breaker units so a narrow Silhouet te of the panel achieved in the direction of the depth axis who the. By aligning the breaker units in egg ner same height, a nearly congruent arrangement of the breaker units in the direction of the depth axis can be accepted. Compared to a height graduation of Unterbre chereinheiten the height of the structure of the panel, in particular in the direction of the projection axis reduces who the. Furthermore, there are advantages in terms of Verwen tion of phase conductors, which serve a contact of the sub-breaker unit. At similar altitude of the sub-breaker units, the use of simple, possibly similarly shaped phase conductors offers, so that an increased number of identical parts can be used to form the panel.

Advantageously, it can be provided that all Unterbre chereinheiten of the same type along the depth axis are arranged behind each other.

Depending on the purpose of the interrupter unit, their construction may differ. Usually, circuit breakers, fast earthing switches, earthing switches, tion switch and load switch, etc. in addition to their Schaltvermö conditions in their form. In particular, the shape differs the design of the relatively movable switch contact pieces. By grouping breaker units of the same type, it is thus possible within a switching field to define a plurality of deepbeams parallel to one another along the depth axis. Different types of interrupter units can be arranged in each case along different depth tracks. This results in advantages in terms of actuation of the individual interrupter units, as in the direction of Tie fenachse, preferably a frontal access to each of the lows is given tracks. For example, the interrupter units, which are arranged on different depth tracks along the depth axis, each take over different functions and in turn be coupled to the one or more interrupter units of the other depth axes. In particular, when using multiple Sam melschienenabschnitten, for example, so-called double busbar sections, so a busbar replacement can be made on the corresponding interrupter units on the ent speaking pathways.

Advantageously, it can further be provided that the switching field several interrupter units of a first type and a plurality of interrupter units of a second type aufwei sen, interrupter units of a type are each arranged on egg ner depth path in line with each other and the depth paths are aligned parallel to and / or on the depth axis.

A division of the interrupter units of the same type on separate depth tracks makes it possible to provide parallel depth tracks extending in the direction of the depth axis in order to arrange similar interrupter units. As a result, at least one of the interrupter units of a type is accessible from the front, ie viewed in the direction of the depth axis. This makes assembly and maintenance easier than knew arrangements. Furthermore, a simplified control of the individual interrupter units is thus made possible, since an access to each at least one of the interrupter units is typically possible.

A further advantageous embodiment may provide that an interrupter unit has a movable switching contact piece whose movement axis extends substantially in the direction of the projection axis.

An interrupter unit has a switching path which is variable in impedance. The switching path can be realized, for example, by contact pieces which can be moved relative to one another and which can be driven relative to one another. For this purpose, at least one of the Schaltkontaktstü- bridge by means of a drive device is movable. A BEWE tion axis of a switching contact piece may be ei ne axis of rotation of a pivotal switching contact piece or a displacement axis of a linearly displaceable angeord Neten switching contact piece, for example. The location of a Bewegungsach se of the movable switching contact piece extends in We sentlichen in the direction of the projection axis. Accordingly, a nearly right-angled arrangement with respect to the depth axis is preferably provided. Thus, a Schaltkontakt- moves, for example, parallel to the projection axis or perpendicular to the projection axis. In connection with the positioning of interrupter units behind one another in the course of the depth axis, it is possible to provide compact envelope contours to design a breaker unit. For example, a breaker unit can be made substantially cylindrical, wherein ei ne movement axis, for example, along the cylinder axis is directed. However, it can also be provided that an interrupter unit is formed, for example disc-shaped, wherein a movement axis of the switching contact piece, in particular a pivotable switching contact piece is parallel to the projection axis, whereby pivoting in one Swivel plane takes place, which is for example perpendicular to the pro jection axis.

A further advantageous embodiment may provide that movable switching contact pieces of several successive curse tend arranged interrupter units are driven by a common drive means.

By means of a common drive device, a plurality of un-breaker units can be actuated, wherein these sub-breaker units are aligned in particular in the direction of the depth axis. This makes it possible to run a simply structured drive chain, for example, to transmit a pushing movement or a rotational movement parallel to the depth axis and so to operate the multiple interrupter units. This provides a possibility, starting from the parallel Ver run to the depth axis, relatively movable switching contact pieces, for example, drive directly and Kraftumlenkeinrich obligations such as rocker arm, pivot lever, etc. to dispense, which would only extend the transmission path from the drive means to a drivable switching contact piece.

Advantageously, it may be provided that a ki nematic chain for transmission of a movement extends substantially parallel to a depth axis.

A kinematic chain may extend substantially parallel to a depth axis. In this case, there is the possibility of forming branches to interrupter units, starting from this kinematic chain extending in parallel. For example, may be arranged at the front side of a drive device which distributed over the kinematic chain in the depth axis into a movement to the ver different interrupter units. In particular, in the case of identically constructed breaker units which are distributed along egg ner common deep path parallel to the depth axis are arranged, it is given the opportunity to cause a synchro nes switching the various interrupter units forth. As a result, a condition is given to switch synchronously in example multi-phase electric power transmission systems. In a simple case example, the use of a rotatable shaft may be provided, wel che along a depth axis with its axis of rotation he stretches. Pinions, swivel levers, etc. can be used to decouple movements in the course of the shaft. For example, it is thus possible to provide a common actuation of several interrupter units via one and the same drive device. In this case, the interrupter units, which can be driven by one and the same drive device, can be arranged both on a single deep path or also on a plurality of substantially parallel tracks aligned with one another. As a result, the effort to form a kinematic chain can be reduced.

A further advantageous embodiment may provide that a plurality of interrupter units in the direction of the Projektionsach se form the vertices of a rectangle and / or a rhombus and / or a triangle.

By fixing at least two parallel aligned parallel paths parallel to the depth axis, along which spaced apart each interrupter units distribute to each other, the possibility is given to provide a symmetrical distribution of interrupter units on the two depth axes. In this case, an arrangement can be made such that form in the direction of the projection axis, the breaker units each corner points of a rectangle, egg nes rhombus or a triangle or any other ge suitable geometric arrangement. In particular, in egg ner similar, aligned symmetrically designed distribution of the interrupter units Ver an arrangement of Un is terbrechereinheiten at vertices, at least one rectangle allows. An offset of the interrupter units to the respective Transverse paths to each other leads to triangular or rhombic positions of the interrupter units. For example, it can also be provided that a common (eg stationary) switching contact piece is used both for switching a first interrupter unit and for switching a second interrupter unit. This is beispielswei se advantageous if a circuit breaker and a grounding switch to operate. In particular, so can be done in a simple form a locking of a grounding switch against a circuit breaker, as always only one of the two sub-breaker units can be clocked with the common switching contact piece kon. This is advantageous, for example, when interrupter units are arranged distributed along two depth tracks, the depth tracks seen in the direction of the projection axis overlap each other (insbesonde re congruent), but are spaced from each other.

A further advantageous embodiment may provide that a plurality of interrupter units are arranged within a common housing Ge.

A common housing can einhausen multiple breaker units, so that they are protected against access from the outside ge. Advantageously, the common housing form an encapsulating, which einhaust the internally arranged in its interrupter units in a closed Flu idaufnahmeraum. This fluid receiving space can be filled with an electrically insulating fluid, in particular a gas, but also an electrically insulating fluid. It can be provided that the several Unterbre chereinheiten, which are each arranged in a common housing, breaker units of the same type. For the interrupter unit of different types different housing may be provided. The housing may preferably be a pressure vessel, so that an electrically insulating fluid arranged in the interior is also under an overpressure. or suppression can be set. Advantageously, the housing, for example, a hollow cylindrical shape (end sides preferably closed), wherein the Hohlzy cylinder axis is preferably aligned substantially parallel to the projecting onsachse. Accordingly, breaker units can be aligned parallel to the hollow cylinder axis. The shape of the end faces can vary, preferably a substantially circular or oval contour can be used. Furthermore, the housing can also be formed by a fusion zen several hollow cylinders, so that an enlargement of the housing provided in the interior of the receiving space takes place. While maintaining the curved lateral surfaces can thus create a rib-like surface, so that the hous se is particularly resistant to differential pressures. In this case, for example, several Teilgehäusebau groups with their lateral surfaces merge into each other, wherein the plurality of sub-housing assemblies are connected to each other on lateral surfaces. The hollow cylinder axes of an individual sub-housing assemblies are seen in the direction of the pro jection axis preferably spaced from each other on a depth track parallel to the depth axis lying.

A further advantageous embodiment may provide that all interrupter units are arranged within a common housin ses.

The arrangement of all interrupter units of the switching field within a common housing has the advantage that the switching field can be configured in a compact form. In particular, in an arrangement of interrupt units units of different types within a common housing, a particularly compact panel can be formed. In addition, for example, monitoring devices need to be performed only once for the interior of the common housing. Thus, for example, an overpressure protection, a density monitoring or a pressure monitoring, etc. for the interior of the common housing le- be formed diglich in a single embodiment. Further, when accommodating all interrupter units in a common housing phase conductors for contacting the interrupter units with each other within the common housing extend. Thus, the number of passages of Pha senleitern is reduced by walls of the housing.

Regardless of the design of the housing for Unterbre chereinheiten a sepa rates busbar housing may be provided for the busbar section. The busbar nengehäuse and the housing are preferably connected rigid angle with each other. For example, the busbar nengehäuse and the housing welded together, glued, potted, screwed, etc. be. In a substantially hollow cylindrical configuration of a common housing, a busbar housing, for example, be connected to the front side with the common housing. However, it can also be provided that the busbar housing is connected on the shell side with the common housing. A connection can be made via nozzles within which phase conductors nenabschnitt to form a stub line between the busbar and the arranged in the housing Unterbre run units. Between the busbar housing and the common housing, a separation of fluid arranged in the interior of the housing and the busbar housing may be provided. For example, this can be done with means of a so-called disc-shaped separation insulator, which enables a fluid-tight seal of the fluid receiving chambers of the respective housing and in turn can be penetrated by a phase conductor.
