Switching arrangement

The invention relates to a switching arrangement comprising a line switch in an upright first power switch capsule section.

A switching arrangement is known, for example, from PCT publication WO 2014/03943 A1. A circuit breaker is arranged there in an upright circuit breaker enclosure section. The switchgear system described there has a compact footprint so that it can also be used in spatially cramped situations. The well-known switchgear is designed in particular for use in turmarti gene structures. Due to its high degree of specialization, the switchgear shows reduced flexibility.

Thus, the object of the invention is to specify a Schaltanord voltage, which can be adapted to different conditions in a simplified manner while maintaining compact dimensions from.

According to the invention, the object is achieved in a switchgear of the type mentioned in that a first isolating switch is arranged in a first isolating switch enclosure section and a second isolating switch is located in a second isolating switch enclosure, the isolating switch enclosure sections being arranged on the shell side of the circuit breaker enclosure.

A switching arrangement is used to switch a phase conductor. Phase conductors are used to transport electrical energy over long distances. For this purpose, the phase conductors are exposed to a potential difference, with an electric current being carried in the phase conductor driven by the potential difference. A circuit breaker can be part of such a phase conductor, for example. The circuit breaker is surrounded by a circuit breaker encapsulation section. The circuit breaker capsule section enables mechanical protection of the circuit breaker received in its interior. A Kapselungsab section, such as a circuit breaker encapsulation section can have electrically conductive and electrically insulating areas. For example, a base body can be designed to be electrically conductive and areas through which a phase conductor is to be passed can have an electrically insulating effect. An electrically insulating area can embed a phase conductor in a fluid-tight manner, for example, so that the phase conductor penetrates a barrier formed by the encapsulation section in a fluid-tight manner. Furthermore, an electrically insulating area can serve to support the phase conductor. The phase conductor through which the electrical current is to be transported can be switched via the circuit breaker. In order to electrically isolate the phase conductor, it can be surrounded by an electrically isolating fluid. This electrically insulating fluid can be prevented from undesired volatilization by the circuit breaker encapsulation section. To this end, an encapsulation section can represent a fluid-tight barrier. If necessary, it can be provided that the electrically insulating fluid in the interior of the circuit breaker encapsulation section is subjected to a pressure which differs from the environment, in particular an overpressure. As a result, the insulation strength of the electrically insulating fluid can be positively influenced. The electrically insulating fluid can wash around the circuit breaker inside the circuit breaker encapsulation housing and can also be used to flush a switching path of the circuit breaker and to act as the switching gas of the circuit breaker. In addition, however, it can also be provided that the circuit breaker has a switching path which is arranged within a tube, so that the electrically insulating fluid is prevented from entering a switching path of the circuit breaker to penetrate. A different fluid can be arranged within the tube. An approaching vacuum can also prevail inside the tube. Within the tube can be arranged relative to each other movable switching contact pieces of the circuit breaker, between which a switching path is formed. Outside the tube of the circuit breaker, the electrically insulating fluid, which is enclosed in the interior of the circuit breaker encapsulation section, can ensure electrical insulation of the circuit breaker. For this purpose, the circuit breaker can be supported in an electrically insulated manner on the circuit breaker encapsulation section or another encapsulation section. As electrically insulating fluids, which are enclosed by the circuit breaker encapsulation section or another encapsulation section, for example fluorine-containing gases or liquids such as sulfur hexafluoride, fluoronitrile, fluoroketone, fluoro olefins or other suitable electrically insulating fluids such as CO ₂ , nitrogen, oxygen and mixtures with these substances are used. In particular, nitrogen can be mixed with an oxygen component.

The use of a first and a second isolating switch enables the circuit breaker to be connected electrically in series with these isolating switches, for example. For this purpose, the first disconnector and the second disconnector can each be arranged upstream and downstream of the circuit breaker on connection sides of the circuit breaker that differ from one another. This makes it possible to isolate the circuit breaker on both sides via the disconnector. Furthermore, there is also the possibility of using disconnectors in order to alternately or simultaneously connect the same connection side via the first disconnector and the second disconnector on one and the same connection side of the circuit breaker the circuit breaker for example with a first and a second cable (or other connection lines). This gives the opportunity to use the first and the second Disconnector make a selection. For example, a circuit breaker can be integrated into a ring line, whereby the circuit breaker can be fed from one or the other half of the ring by alternately connecting the first and the second disconnector, or a ring can be looped through when switched on at the same time .

The first and second circuit breakers are in a first circuit breaker encapsulation section and in a second

Disconnector enclosure section arranged. The isolating switch capsule sections are preferably metically separated from one another, so that in the interior of each of the capsule sections separate fluids, in particular

electrically insulating fluids, can be arranged. In this way, electrically insulating fluids separated from one another can be encased via the various encapsulation sections.

In order to allow a phase conductor to pass from one encapsulation section to the other encapsulation section, an area is preferably designed to be electrically insulating, so that the fluids are separated and an electrically insulated transition of the phase conductor between the individual encapsulation sections is enabled. For example, post insulators can be used for this purpose, which are necessary to keep the phase conductors or the phase conductor spaced apart from an electrically conductive area of a wall of an encapsulation section. For example, it is possible to make the encapsulation section electrically conductive in one area and only the areas in which the phase conductor passes through a wall (barrier) of an encapsulation section,

design electrically insulating. So-called electrically insulating bushings can be used for the phase conductor to pass through a wall of an encapsulation section. These are, for example, disk-shaped Insulators which, in an electrically insulating manner, close an opening, for example in a base body of the encapsulation section.

A bushing can be designed to be fluid-tight, if necessary a bushing or the phase conductor passed through can have a channel through which an electrically insulating fluid can pass from one encapsulation section to another encapsulation section. The encapsulation sections can preferably be hermetically separated from one another and only an electrically insulated crossing of the corresponding phase conductors between encapsulation sections can be permitted.

A circuit breaker encapsulation section can be designed, for example, essentially tubular, the tube axis being aligned approximately in a vertical. As a result, an upright circuit breaker encapsulation section is formed on which the shell side the disconnector encapsulation sections are arranged. Correspondingly, if necessary, starting from the circuit breaker positioned inside the circuit breaker enclosure section in radial directions, positioning of the isolating switch enclosure sections and the isolating switch inside the same made light possible. For connecting encapsulation sections, these can e.g. Have flanges via which the encapsulation sections are connected to one another. Flanges are also suitable for the passage of a phase conductor from one Kapselungsab section to another encapsulation section as well as for receiving a bushing.

By choosing the positions of the flanges, the position of the encapsulation sections relative to one another can be determined. With regard to the execution of the isolating switch enclosure sections and the filling of the same, the procedure can be analogous to the circuit breaker enclosure section.

A disconnector encapsulation section can be connected directly or indirectly to a circuit breaker encapsulation section be scheduled. In the case of an indirect attachment, for example by using an intermediate encapsulation section, an enlarged spacing of the isolating switch encapsulation section from the circuit breaker encapsulation section can take place. A further circuit breaker encapsulation section and / or a further disconnector encapsulation section, etc. can serve as the intermediate encapsulation section. Flanges used for attachment should be aligned on one axis. A second, preferably structurally identical, power switch encapsulation section can also serve as the intermediate encapsulation section. The Zwischenkapselungsab section can also be used to deflect a phase conductor and thus prevent the same direct, linear passage (for example in the direction of an aligned axis of the flanges).

A further advantageous embodiment can provide that the disconnector encapsulation sections are aligned with one another.

The disconnector encapsulation sections can preferably be aligned cursing one another. The envelope contour of the corresponding disconnection switch capsule sections is approximately the same in the direction of an escape axis. As a result, slim switch arrangements with a small footprint can be used for example. Furthermore, a simplified possibility is given, for example, to bring cables for integrating the switching arrangement into an electrical power transmission network to the switching arrangement and to connect them to it. The disconnector encapsulation sections can also be embodied in an essentially tubular manner analogously to the essentially tubular circuit breaker encapsulation section. In this case, the cross section of an essentially tubular circuit breaker encapsulation section should preferably be selected to be larger than the cross section of a circuit breaker encapsulation section. Before given, the disconnector encapsulation sections can also be designed identically. The Disconnector encapsulation sections can, for example, provide angled access to the interior of the circuit breaker encapsulation section. In the case of an essentially tubular disconnector encapsulation section, a flange for connection to a circuit breaker section, for example, can be located on one side so that the pipe axes of the circuit breaker encapsulation housing and a disconnector encapsulation section arranged on the shell side are essentially parallel. For example, it is possible to lead a phase conductor out of the inside of the circuit breaker encapsulation section on the jacket side via a disconnector attached on the jacket side and to redirect it at an angle within the circuit breaker encapsulation section. For example, it is possible to deflect the phase conductor section by approx. 90 ° inside a disconnector enclosure section. By choosing the angular position, an aligned alignment of the disconnector enclosure sections can be achieved.

An advantageous embodiment can provide that the

Disconnector encapsulation sections are aligned in alignment with one another in the direction of a vertical axis of the first circuit breaker encapsulation section.

A vertical axis of the circuit breaker encapsulation section can be determined, for example, by a tube axis of the circuit breaker encapsulation section. The vertical axis can preferably be aligned in a vertical direction. A shell-side attachment of the disconnector encapsulation sections can take place along the vertical axis at a distance from one another, so that the disconnector encapsulation sections are spaced apart on an axis which is aligned essentially parallel to the vertical axis of the circuit breaker encapsulation section. In particular when using angled disconnector encapsulation sections, an aligned alignment of the same can be provided, but an opposite alignment of an angular branching off of the Circuit breaker encapsulation sections can be provided. It is possible, for example, to supply lines such as cables to the circuit breaker via the circuit breaker encapsulation sections on the circumference of the circuit breaker encapsulation section and to enlarge the base area of the switching arrangement only slightly, preferably at one and the same position on the circumference. Aligned along a vertical axis

Disconnector encapsulation sections are preferably connected directly to the same circuit breaker encapsulation section. For the composite on the circuit breaker encapsulation section vorgese Henen flanges are aligned on the shell side in the same radial direction, but spaced apart in the direction of a vertical axis.

A further advantageous embodiment can provide that the disconnector encapsulation sections are aligned transversely to a vertical axis of the first circuit breaker encapsulation section in alignment with one another.

A transverse axis can, for example, pass the vertical axis of the circuit breaker encapsulation section essentially perpendicularly, in particular intersect the vertical axis, with the disconnector encapsulation sections being able to be positioned on opposite sides on the shell side of the circuit breaker encapsulation section. Thus, there is a perpendicular alignment of the various axes to one another, with the disconnector encapsulation sections being aligned with one another in the direction of the transverse axis. This is particularly advantageous when the disconnector encapsulation sections are intended to provide an angled branch on the shell side of the circuit breaker encapsulation section and these are to be aligned with the same direction. For example, it is possible to feed a first cable via the first disconnector encapsulation section and a second cable via the second disconnector encapsulation section to the circuit breaker encapsulation section, the two cables from one and the same direction to the Strive for circuit breaker encapsulation section. When using flanges to connect different Kapselungsab sections to each other, use of a Kapselungsab section can be provided, which brings about an indirect bond between the circuit breaker enclosure section and the disconnector enclosure section. Another circuit breaker encapsulation section can be used for spacing. For example, it is possible to align two or three circuit-breaker capsule sections, preferably of the same type, parallel to one another and to flange them together. For this purpose, coupling flanges can be used on the shell side, which connect the circuit-breaker encapsulation sections with one another at a rigid angle. If necessary, coupling flanges can be penetrated by a phase conductor. Preferably, flanges for flanging disconnector encapsulation sections and coupling flanges are diametrically opposite on the shell side on a circuit breaker encapsulation section. Thus, a linear, angularly rigid combination of several circuit breaker encapsulation sections and several disconnector switch encapsulation sections is possible, with the flanges used for the connection advantageously being aligned with one another on an axis.

Advantageously, it can further be provided that the disconnector encapsulation sections each have a cable connection, the cable connections on the disconnector encapsulation sections each being aligned opposite to one another.

A cable connection on a circuit breaker enclosure section provides the option of connecting a cable to the circuit breaker enclosure section. By using an angled design of a circuit breaker enclosure section, a shell-side introduction of at least one phase conductor, which is made available by the cable, can be made into the interior of the circuit breaker enclosure section. By aligning the angular position The cables strive from different directions on the circuit breaker encapsulation section or strive from the same direction on the circuit breaker encapsulation section. For example, cable connectors can serve as the cable connection, which can be plugged onto an outer cone of the cable connection, for example. Conversely, however, the cable connection can also have an essentially conical socket, with a corresponding counterpart on the cable enabling electrical contact. Regardless of its specific design, a cable connection has the option of feeding a cable in a dielectrically controlled and stable manner to the switching arrangement and feeding the phase conductor of the cable through a wall of a disconnector enclosure section in an electrically insulated and electrically stable manner.

An opposite orientation of the cable connections makes it possible, for example, to let cables run from opposite directions onto the circuit breaker encapsulation section and to let the corresponding cables open out at the first disconnector encapsulation section or at the second disconnector encapsulation section. The opposite orientation relates to the insertion direction of the phase conductor of the respective cable on the respective disconnector enclosure section. Preferably, the opposite alignment of the cable connections can be provided in the case of a cursing alignment of the disconnector encapsulation sections in the direction of the vertical axis of the circuit breaker encapsulation section. It is thus possible, for example, to supply and discharge a phase conductor to the power switch on a constant base of the Schaltan order.

A further advantageous embodiment can provide that the disconnector encapsulation sections each have a cable connection, the cable connections to the Isolation switch enclosure sections are each directed in the same direction.

Aligning the cable connections of the different disconnector encapsulation sections in the same direction enables access to different cables from one and the same direction to the respective disconnector encapsulation sections. In particular with an alignment of the circuit breaker capsule sections in alignment with a transverse axis, there is the possibility of distributing several circuit breaker capsule sections on the circumference of the circuit breaker capsule section and each from one and the same direction cables to the

Lead switching arrangement. With regard to the design of the cable connections, reference is made to the above.

A further advantageous embodiment can provide that an earthing switch is arranged at least on one of the disconnector encapsulation sections.

An earthing switch is used to apply earth potential to a phase conductor. This is particularly desirable for safety circuits. For example, a ground fault can be provoked even in the event of a faulty connection, which usually results in an automated safety shutdown. In this respect, an earthing switch is a safety system, by means of which, if necessary, earth potential can be connected to the phase conductor, for example a disconnector or a circuit breaker. If necessary, depending on the function of the earthing switch, a particularly rapid connection of earth potential can take place. So-called high-speed earthing switches are to be used for this purpose. It can also be provided that a make-proof earthing switch is used, which can forcefully earth the phase conductor even when the phase conductor is live. The earthing switch can protrude into the interior of the respective disconnector enclosure section and earth the phase conductor located there. The earth potential can be made available, for example, by electrically conductive areas of the isolating switch encapsulation section, which, for example, carry ground potential.

Another advantageous embodiment can provide that at least one of the disconnectors is designed as a three-position device.

With a three-position device, one and the same An

drive arrangement a circuit breaker contact piece or several circuit breaker contact pieces that carry the same potential, drive and operate on the one hand a circuit breaker and on the other hand an earthing switch, so that the circuit breaker and the earthing switch are positively locked. A change from the isolating function to the earthing function can take place via a neutral position of a movable isolating switch contact piece, with the isolating switch and the earthing switch being open in the neutral position and alternating switching on of the isolating switch or the earthing switch via one and the same drive arrangement is guaranteed.

Preferably, the disconnector contact piece of a Dreistel processing device can be designed as a linearly movable disconnector contact piece, with the switching point for the disconnector on the one hand and the switching point for the earthing switch on the other hand being provided on the opposite end of the disconnector contact piece.

A further advantageous embodiment can provide that a drive arrangement of the circuit breaker is arranged flanked by two disconnector encapsulation sections.

In order to achieve a compact design, a drive arrangement of the circuit breaker can be flanked by isolating switch encapsulation sections. For example, on the face of the upright Circuit breaker encapsulation sections the positioning of a drive arrangement for the circuit breaker can be provided. A circuit breaker encapsulation section can at least partially span the drive arrangement. On the drive arrangement on relatively movable switching contact pieces of the circuit breaker can be driven. A flanking by disconnector encapsulation sections enables an efficient use of installation space on the switching arrangement. The installation space available in the direction of a vertical axis of the circuit breaker is used for positioning the drive device of the circuit breaker. Furthermore, the drive device can experience mechanical protection through the flanking disconnector encapsulation sections. The flanking disconnector encapsulation sections should preferably lie transversely to a vertical axis of the circuit breaker encapsulation section and should preferably be arranged congruently in alignment. Via a kinematic chain, starting from the drive arrangement, a switching movement can be transmitted into the interior of the circuit breaker encapsulation section. The kinematic chain can penetrate a barrier of the circuit breaker encapsulation section in a fluid-tight manner and transmit a movement in a fluid-tight manner through the barrier, for example a wall.

A further advantageous embodiment can provide that the first power switch encapsulation section is arranged flanked by a circuit breaker encapsulation section and a secondary housing.

So-called secondary devices, which are arranged on the switching arrangement within a secondary housing, are necessary to control the switching arrangement or to actuate the switching arrangement. Secondary devices are, for example, control arrangements, measuring devices, protective devices, etc., which are used to operate the switching arrangement. The secondary housing and the circuit breaker capsule section, which the circuit breaker capsule section flank should, if necessary, be arranged on opposite sides of a transverse axis, which is aligned essentially perpendicular to a vertical axis of the circuit breaker encapsulation section. It can advantageously be provided that the secondary housing is spanned by a further isolating switch encapsulation section or in turn spans a further isolating switch enclosure section. Thus, the area which is claimed by the switching arrangement is used in an advantageous manner.

The secondary housing can be attached to the circuit breaker enclosure section so that the circuit breaker enclosure section carries the secondary housing. The secondary housing can be fastened to a circuit breaker encapsulation section and thus, for example, also be carried indirectly by the power switch encapsulation section.

A further advantageous embodiment can provide that the first and a second circuit breaker encapsulation section are arranged between a first circuit breaker encapsulation section and a second circuit breaker encapsulation section.

The use of two circuit breaker encapsulation sections makes it possible to increase the number of circuit variants that can be implemented with the switching arrangement. The first as well as the second circuit breaker enclosure section should be constructed essentially identically and aligned axially parallel. For example, in the case of an essentially tubular configuration of the two circuit breaker encapsulation sections, the tube axes can be configured parallel to one another. Preferably, the tube axes can be arranged in a vertical manner, so that both the first and the second circuit breaker capsule section are arranged upright. Correspondingly, the circuit breakers arranged in the interior of the circuit breaker encapsulation sections are likewise preferred aligned upright. A connection of both the first and the second circuit breaker encapsulation section is enabled via the first and the second disconnector encapsulation section. For this purpose, the corresponding phase conductor is distributed via nodes between the disconnectors or the circuit breakers. The first isolating switch enclosure section and the second isolating switch enclosure section can be connected on the shell side to one and the same circuit breaker enclosure section.

However, it can also be provided that each of the isolating switch encapsulation sections is connected to one of the circuit breaker encapsulation sections. In this case, one circuit breaker encapsulation section acts in each case for the other circuit breaker encapsulation section as an intermediate encapsulation section. The power switch capsule sections are preferably connected to one another at rigid angles via coupling flanges. The coupling flanges are advantageously aligned with flanges on which a disconnector enclosure section is arranged. For example, an indirect connection of a circuit breaker enclosure section and a disconnector enclosure section is possible.

A further advantageous embodiment can provide that the first circuit breaker and the first circuit breaker and the second circuit breaker and the second circuit breaker are electrically connected in series and between the first circuit breaker and the second circuit breaker a node from which a first and a second, the The rod having the respective circuit breaker and disconnector continues.

The first circuit breaker and the first disconnector are preferably connected in series with one another. Likewise, the second circuit breaker and the second disconnector are preferably connected electrically in series with one another. The first circuit breaker and the first isolating switch thus form a first strand, the second circuit breaker and the second disconnector form a second line. The two strands can be electrically connected to one another in a knot, with the beige strands continuing from the knot. In the case of a series connection of circuit breakers and disconnectors to one another, the node should preferably be formed on the side of the strand on which direct access to a connection side of the circuit breaker is granted. This enables direct contacting of the respective connection sides of the circuit breakers at the same node. In addition, use of a third line having a third circuit breaker and a third disconnector can also be provided. The circuit breakers are electrically conductively coupled to a connection side in a common node, the strands with the respective isolating switches continuing from the node.

A further advantageous embodiment can provide that the first circuit breaker and the first circuit breaker and the second circuit breaker and the second circuit breaker are each electrically connected in series and form a first and a second strand, with the first circuit breaker and the first circuit breaker in the first strand a node with the formation of a stitch for a second circuit breaker and the second disconnector is arranged on facing second strand.

A node can be arranged between a first disconnector such as a first circuit breaker, so that the first strand is segmented by the node. The second line can extend from the node point, wherein the second circuit breaker can preferably be arranged directed towards the node point. This gives the possibility of designing the second strand as a branch which starts from the node between the first disconnector and the first circuit breaker. A further advantageous embodiment can provide that the switch arrangement is encapsulated with one pole.

A single-pole encapsulation of a switching arrangement, at least in sections, enables phase conductors of different potentials to be positioned electrically isolated from one another on the one hand, and to keep them mechanically separated from one another by the encapsulation sections on the other. For example, it is possible to design a three-phase switching arrangement with three single-pole encapsulation sections. Preferably, the encapsulation sections of the individual poles can be designed identically and arranged in parallel. This results in a compact arrangement, which enables multiple use of Kapselungsabschnit th at different poles.

A further advantageous embodiment can provide that the respective encapsulation sections are flanged to one another, in particular in a fluid-tight manner.

The different encapsulation sections can each receive phase conductors of different configurations in their interior. In order to enable a phase conductor to pass from one encapsulation section to another encapsulation section and thus a transfer of an electrical one

To enable current through walls of the encapsulation sections, the encapsulation sections can have flanges. The flanges are preferably designed as ring flanges which allow the phase conductor to pass. Preferably electrically insulating bushings, e.g. so-called bushing insulators, which close the flange opening in a fluid-tight manner and a

electrically insulating support of the phase conductor guarantee th. The flanges of the encapsulation sections should be preferably designed as screw flanges, preferably corresponding electrically insulating in a flange gap Post insulators can be inserted to enable a fluid-tight closure of a flange opening.

In the following, an embodiment of the invention is shown schematically in a drawing and described in more detail below be.

The switching arrangement shown in FIG. 1 in the first embodiment is designed with three poles. A single-pole encapsulation is provided, i.e. each phase conductor (pole) of a multiphase electrical power transmission system is arranged within encapsulation sections, each phase conductor being separated from the other phase conductors of the system via separate encapsulation sections. Accordingly, the switching arrangement has a structure in which several poles of the same type are arranged parallel to one another, with these being supported on a common support frame 1. Furthermore, a common secondary housing 2 is provided, which is posted on one or more Kapse treatment sections of the switching arrangement and indirectly supported by the support frame 1 via this. FIG. 1 in its perspective view is an example of the structure of the various variants, as shown in FIGS. 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 and 13.

The individual design variants differ in the structure and use of the individual poles. What is common to the different design variants is that poles of the same structure are arranged one after the other, so that in analogy to FIG. 1, corresponding perspective views of the different design variants result. Regardless of the design variant, all variants have in common that there is a first input INI, a second input IN2 and an output OUT. In all variants, a connection of cables is provided at the first input INI, the second input IN2 and the output OUT.

The first variant embodiment of a switching arrangement according to Fi gur 1 has single-pole insulation. The other design variants are also designed with single-pole insulation. As an example, one of the switching poles, as known from FIG. 1, is shown in section in FIG.

The switching arrangement in the first variant has a first circuit breaker 3.1. The first circuit breaker

3.1 is from a first circuit breaker enclosure section

4.1 surrounded. The first circuit breaker encapsulation section 4.1 has an essentially tubular shape, a tube axis serving as a vertical axis, so that the first circuit breaker encapsulation section 4.1 is oriented in an upright position. Following the upright position of the first circuit breaker encapsulation section 4.1, the first circuit breaker 3.1 is arranged essentially centrally in the interior of the first circuit breaker encapsulation section 4.1. In the present case, the first circuit breaker 3.1 is equipped with a vacuum interrupter, which has a tubular body that closes a vacuum inside. Inner half of the tube body movable switching contact pieces 5 are arranged relative to one another. In order to achieve a relative movement of the switching contact pieces 5 to one another, a drive device 6 is connected via a kinematic chain 7 to at least one of the switching contact pieces 5 which can be moved relative to one another. In the present case, the kinematic chain 7 has an axially displaceable switching rod, which is essentially movable along the vertical axis of the first power switch cap selungsabschnitts 4.1. Accordingly, there is a linear relative movement of the switching contact pieces 5 to one another. The kinematic chain 7 is arranged on a first connection side 8 of the first circuit breaker 3.1. At the opposite end of the first circuit breaker 3.1 a second connection side 9 of the first power switch 3.1 is arranged. The first circuit breaker 3.1 can be connected to further sections of a phase conductor via the two connection sides 8, 9. The first circuit breaker 3.1 represents a switchable section in a phase conductor.

On the shell side, a first connection flange 10, a second connection flange 11 and a third connection flange 12 are arranged on the first circuit breaker enclosure section 4.1. The first and the second connection flange 10, 11 are arranged diametrically opposite one another on the shell side, so that they lie on an axis which intersects the vertical axis of the first circuit breaker encapsulation section 4.1. The second connection flange 11 and the third connection flange 12 are also axially spaced apart, but the axial distance runs essentially parallel to the vertical axis of the first circuit breaker encapsulation section 4.1, so that the first connection flange 10 and the second connection flange 11 have access to the first connection side 8 of the allow first circuit breaker 3.1, the third connection flange 12 grants access to the second connection side 9 of the first circuit breaker 3.1.

A first isolating switch enclosure section 13, a second isolating switch enclosure 14 and a third isolating switch enclosure section 15 are arranged on the connection flanges 10, 11, 12. The isolating switch capsule sections 13, 14, 15 are each constructed identically and have a substantially tubular structure. The tube axes are essentially aligned parallel to the vertical axis of the first circuit breaker encapsulation section 4.1.

In order to impress a movement on a respective isolating switch contact piece of isolating switches 16, 17, 18, the front end of the respective isolating switch enclosure section 13, 14, 15, which has a cable connection 22 is arranged opposite, in each case a disconnector drive 23 is arranged. In the present case, a separate isolating switch drive 23 is provided for each of the isolating scarf terkontaktstück at each of the isolating switch capsule sections 13, 14, 15. Possibly. A disconnector drive can also be used to drive multiple disconnector contact pieces with multiple poles.

A positioning of the cable connections 22 is provided in such a way that the cable connections 22 on the first and second isolating switch enclosure sections 13, 14 are aligned in the same direction, whereas the cable connection 22 of the third isolating switch enclosure section 15 is opposite to the cable connections 22 of the first isolating switch enclosure section 13 and the second isolating switch enclosure section 14 is aligned.

Due to the position of the connecting flanges 10, 11, 12 on the first circuit breaker encapsulation section 4.1, the second circuit breaker encapsulation section 14 and the third circuit breaker encapsulation section 15 are aligned with their envelope contour in alignment with one another, the alignment axis being arranged parallel to the vertical axis of the first circuit breaker encapsulation section 4.1. Furthermore, the first isolating switch enclosure section 13 and the second isolating switch enclosure section 14 are also aligned aligned with one another, the alignment axis being essentially perpendicular to the vertical axis of the first circuit breaker enclosure section 4.1 and preferably the alignment axis passing through the vertical axis of the first circuit breaker enclosure section 4.1.

In the disconnector encapsulation sections 13, 14, 15 disconnectors 16, 17, 18 are arranged each Weil. The first, the second and the third disconnector 16, 17, 18 are so-called three-position devices, their movable disconnector contact piece being linearly displaceable. The displacement axis of the disconnector contact piece is selected in such a way that it is oriented essentially transversely to the respective vertical axis and the respective disconnector contact piece is assigned to a connection flange 10, 11, 12 at the end. In the flange connection between the connection flanges 10, 11, 12 and the isolating switch enclosure sections 13, 14, 15, a fluid-tight, electrically insulating barrier is arranged so that the interior of the first circuit breaker enclosure section 4.1 is closed in a fluid-tight manner. A mating contact piece of the respective isolating switch 16, 17, 18 is positioned over the fluid-tight, electrically insulating barrier. The fluid-tight barrier is traversed by a connecting conductor 20, by means of which a mating contact piece of the respective isolating switch contact piece is electrically contacted with the first connection side 8 or the second connection side 9 of the first power switch 3.1. The shape of the respective connecting conductors 20 can vary as required. Opposite to the disconnector counter contact piece, a ground contact 21 is arranged on the respective disconnector enclosure section 13, 14, 15. By linear displacement of the disconnector contact piece, it can be moved into the respective mating contact piece on the one hand, whereupon an isolation path from the grounding contact 21 is provided. If necessary, the disconnector contact piece can also be stored in a neutral position (as shown in the figures). For grounding, the disconnector contact piece is moved linearly in the direction of the grounding contact 21 and light enables grounding of the respective sections 13, 14, 15 connected to the disconnector enclosure. A phase conductor of the respective cable is connected to the respective isolating switch 16, 17, 18 in an electrically conductive manner. In order to make stable electrical contact with one cable in each case with the respective isolating switch 16, 17, 18, cable connections 22 are provided. The cable connections 22 each have essentially coaxial sockets which each have an end face of the respective disconnect switch encapsulation section 13, 14, 15 stretch and close. In this socket of the respective cable connection 22 an oppositely shaped connection fitting of the respective cable can be inserted, so that a dielectrically and mechanically stable termination of the respective cable on the switching arrangement is given.

In the circuit variant, as shown in Figure 2, it is possible to alternately or in parallel electrically connect the two cables located at the inputs INI, IN2 via the first disconnector 16 and the second disconnector 17 to the first connection side 8 of the circuit breaker 3.1 . Via the third isolating switch 18, a cable connected to the output OUT can, if necessary, be connected in an electrically conductive manner to the second connection side 9 of the circuit breaker 3.1. Conversely, the cables can be grounded via the respective isolating switches 16, 17, 18 by means of electrical contacting at the respective grounding contact 21.

In the figure 3 a second variant of a switching arrangement is shown. Here, an alternative design of the disconnector enclosure sections 13.1, 14.1, 15.1 is provided. The electrical circuit that can be implemented by the switching arrangement in the second embodiment according to FIG. 3, however, corresponds to the electrical circuit that is shown in FIG. 2 and described above.

The disconnectors 16.1, 17.1, 18.1 used are not, however, three-position devices, but rather disconnectors that enable connection or disconnection of cable connections 22 on the first connection side 8 and the second connection side 9 of the first circuit breaker 3.1. In order to be able to ground the cables that can be connected to the inputs INI, IN2 and the output OUT, separate earthing switches 24 are provided which have a grounded earthing contact piece starting from a wall of the respective isolating switch section 13.1, 14.1, 15.1 in the direction of the isolating switch contact piece. This makes it possible to use fast earthing switches 24, for example. Furthermore, there is the possibility, with the isolating switches 16.1, 17.1, 18.1 also switched on, the first and second connection side 8, 9 of the circuit breaker 3.1 to he.

Notwithstanding the cable connections 22, as known from FIG. 2, cable connections 22.1 are provided here, which on the outside of the respective isolating switch enclosure section 13.1, 14.1, 15.1 provide an electrically insulating outer cone 25 via which a phase conductor from the interior of the respective Isolation switch capsule section 13.1, 14.1, 15.1 is led to the outside. Contact with the phase conductors of the cables can be made there via so-called cable plugs 26, which terminate the corresponding cables. For this purpose, the cable connectors 26 are plugged onto the outer cones 25 in a complementary manner. In the present case, as shown in FIG. 3, so-called angled connectors are used, which means that the cable connectors 26 can each be redirected to the respective phase conductor of a cable to be connected. The cable connections 22.1 of the first isolating switch enclosure section 13.1 and the second isolating switch enclosure section 14.1 are aligned opposite to each other, whereas the cable connections 22.1 of the second isolating switch enclosure section 14.1 and the third isolating switch enclosure section 15.1 are aligned in the same direction. The arranged on the first connection flange 10 and on the second connection flange 11 of the first circuit breaker encapsulation section 4.1 disconnect switch encapsulation sections 13.1, 14.1 are aligned in the direction of an alignment axis which is perpendicular to the vertical axis of the first circuit breaker encapsulation section 4.1. The second disconnector encapsulation section 14.1 as well as the third disconnector encapsulation section 15.1 are with their respective envelope contours aligned with an alignment axis which is aligned essentially parallel to the vertical axis of the first circuit breaker encapsulation section 4.1.

With the third variant, the fourth variant, the fifth, the sixth and the seventh variant, as shown in Figures 4 to 13, circuit variants can be implemented which include a first circuit breaker 3.1 and a second circuit breaker 3.2 or a third circuit breaker 3.3 need. The circuit breakers 3.1, 3.2, 3.3 each have the same design.

In the third embodiment, the first power switch 3.1 is surrounded by a first power switch enclosure section 4.1. The second circuit breaker 3.2 is surrounded by a second circuit breaker encapsulation section 4.2. The two circuit breakers 3.1, 3.2 and the two circuit breaker encapsulation sections 4.1, 4.2 have essentially the same structure. Both the circuit breakers 3.1, 3.2 and the circuit breaker capsule sections 4.1, 4.2 essentially correspond to the first circuit breaker 3.1 and the first circuit breaker capsule section 4.1, as is known from the first exemplary embodiment and the second exemplary embodiment. Correspondingly, a kinematic chain 7 is assigned to each circuit breaker 3.1, 3.2, which causes a relative movement of switching contact pieces 5 which can be moved relative to one another via a respective drive device 6. The circuit breakers 3.1, 3.2, analogous to the circuit breakers 3.1 of the first and the second variant, each have a connection side 8 and a second connection side 9, the first connection side 8 being the side on which a movement is coupled in via the kinematic Chain 7 takes place. On the opposite side of the circuit breakers 3.1, 3.2 there is a second connection side 9 arranged. The secondary housing 2 is supported via the first isolating switch enclosure section 13.

The first circuit breaker encapsulation section 4.1 has a second connection flange 11 and a third connection flange 15. A second disconnector encapsulation section 14 is arranged on the second connection flange 11. On the third connection flange 12, a third isolating switch capsule section 15 is arranged.

The second circuit breaker encapsulation section 4.2 of the second circuit breaker 3.2 has a first connection flange 10. A first disconnector encapsulation section 13 is arranged on the first connection flange 10. The disconnector encapsulation sections 13, 14, 15 of the third embodiment are similar to the disconnector encapsulation sections 13, 14, 15 of the first embodiment and have the identical structure and function with regard to the disconnectors 16, 17, 18 respectively. Accordingly, the third disconnector 18 is electrically connected to the second connection side 9 of the first circuit breaker 3.1, whereas the second disconnector 17 is electrically connected to the first connection side 8 of the first circuit breaker 3.1. The connection flanges 10, 11, 12 each diametrically opposite coupling flanges 28 are arranged on the first circuit breaker encapsulation section 4.1 and the second circuit breaker encapsulation section 4.2. The coupling flanges 28 are used to mechanically bond the circuit breaker encapsulation sections 4.1, 4.2, so that these are connected upright and aligned parallel to one another. Furthermore, if necessary, coupling flanges 28 can serve to pass a phase conductor. The coupling flanges 28, which are located on the first connection side 8 of the circuit breakers 3.1, 3.2, are penetrated by a phase conductor, so that a permanent electrical contact (node) of the two circuit breakers 3.1, 3.2 is possible. If necessary, the coupling flanges 28 can allow a fluid to pass from one circuit breaker encapsulation section 4.1 to the other circuit breaker encapsulation section 4.2 and vice versa. It can, however, also be provided that fluid-tight barriers are arranged there so that each of the power switch capsule sections 4.1, 4.2 can each receive a separated fluid. The first connection flange 10 on the second circuit breaker encapsulation section 4.2 is arranged on the shell side on the second connection side 9 of the second circuit breaker 3.2, so that electrical contact between the first disconnector 16 and the second connection side 9 of the second circuit breaker 3.2 is made possible. This arrangement makes it possible for the two power switches 3.1, 3.2, starting from the first disconnector 16 (input INI), to be connected electrically in series to the third disconnector 18 (from output OUT). Furthermore, a branch to the input IN2 is formed at the node between tween the two circuit breakers 3.1, 3.2, which can be separated via the second isolating switch 17.

A fourth variant embodiment of a switching arrangement is shown in FIGS. The basic structure of the fourth variant corresponds to the third variant of a switching arrangement shown in FIGS. 4 and 5. Therefore, only the differences are discussed below. Notwithstanding the third embodiment variant, as shown in Figures 4 and 5, the secondary housing 2 is positioned on the support frame 1 and carried directly by this. Furthermore, contrary to the third embodiment variant according to FIGS. 4 and 5, the use of disconnectors 16.1, 17.1, 18.1 is provided, which use the same disconnector enclosure sections 13, 14, 15, but instead of being designed as a three-position device, each has a separate earthing switch drive for a separate rates earthing contact piece 29 have. The ground contact pieces 29 can so with a different movement profile be moved relative to the disconnector contact pieces. For example, it is possible to use high-speed earth electrodes, which, for example, can also be switched on permanently on live phase conductors.

A fifth and sixth variant of a switching arrangement are shown in FIGS. 8 and 9 and in FIGS. 10 and 11. The design shown in Figures 8, 9 and 10, 11 mechanically has the same structure. Only the position of the inputs INI, IN2 and the output OUT vary, which results in different circuit variants between the input INI, IN2 and the output OUT.

First, the mechanical construction and the electrical construction of the fifth variant embodiment of a switching arrangement is described with reference to FIGS. Starting from the third embodiment variant of a switching arrangement shown in FIGS. 4 and 5, the position of the first isolating switch section 13 is changed. Instead of being positioned on a first connection flange 10, which is angeord net on a second connection side 9 of the second circuit breaker 3.2, the first connection flange 10 is now positioned on the casing side on the first connection side 8 of the second circuit breaker 3.2. Accordingly, a phase conductor on the first connection side 8 via the first connection flange 10, passing this, can be connected to the first disconnector 16 via the movable disconnector contact piece. Furthermore, the first isolating switch 16 can be connected to a cable via a corresponding cable connection 22, which cable forms the input INI. The circuit breaker capsule sections 4.1, 4.2 are connected to each other via coupling flanges 28 (nodes), these each aligned with an alignment axis which the vertical axes of the circuit breaker capsule sections 4.1, 4.2 pass, with respect to the connection flanges 10, 11, 12 on the shell side. The second connection side 9 of the second circuit breaker 3.2 is with the passage of coupling flanges 28 with the second Connection side 9 of the first circuit breaker 3.1 electrically connected (node). Furthermore, the second connection side 9 from the first circuit breaker 3.1 and from the two th circuit breaker 3.2 is connected to the third disconnector 18. A cable, which functions as an input IN2, is connected to the third isolating switch 18 via a cable connection 22.

On the first connection side 8 of the first circuit breaker 3.1, contact is provided with the second isolating switch 17, which in turn is connected to a cable via a cable connection 22. This cable serves as the output OUT. Correspondingly, such an arrangement is given in which the cable connections 22 at the input IN2 and at the output OUT are directed opposite to one another, the respective disconnector encapsulation sections 14, 15 being aligned with one another with respect to a vertical axis and opposite cable connections 22 bearing opposite to one another. Furthermore, the first isolating switch enclosure section 13 and the second isolating switch enclosure section 14 are also aligned, the alignment axis crossing the vertical axes of the two power switch enclosure sections 4.1, 4.2. The cable connections 22 from the first isolating switch enclosure section 13 and from the second isolating switch enclosure section 14 are aligned in the same direction. With such a circuit, the fifth variant, as shown in Figures 8 and 9, perform the same switching task or switching function as the third variant, which is shown in Figures 6 and 7, but combined disconnection and earthing switches are used. There are two strands, each having a circuit breaker 16, 17 and a circuit breaker 3.1, 3.2 in series, formed. The two strands continue from a node, the circuit breakers 3.1, 3.2 at the node being in permanent electrical contact. Figures 10 and 11 show a sixth embodiment of a switching arrangement. The mechanical structure of the switching arrangement shown in Figures 8 and 9 and 10 and 11 is chosen to be similar. Only the position of the second input IN2 and the output OUT vary. In the present case, the second input IN2 is positioned on the second isolating switch enclosure section 14, whereas the output OUT is located on the third isolating switch enclosure section 15. Such a circuit means that there is one series circuit each at both the first and the second input INI, IN2

Disconnector 16, 17 and a circuit breaker 3.1, 3.2 arranged, the node connecting the two circuit breakers 3.1, 3.2 (second connection side 9) forming an output OUT which can be separated by a third disconnector 18.

Thus, by swapping the positions of the second input IN2 for the output OUT (compare FIGS. 8, 9, 10, 11), a different use of the same structure of the switching arrangement is made possible.

The seventh embodiment variant of a switching arrangement shown in FIGS. 12 and 13 further develops the fourth embodiment variant of a switching arrangement known from FIGS. 6 and 7. In the fourth embodiment variant, a first disconnector 16.1 is arranged at the input INI, which

is electrically connected in series with the second circuit breaker 3.2 ge. At the output OUT, a third isolating switch 18.1 is electrically connected in series with the first power switch 3.1. A node is formed between the two first connection sides 8 of the first and the second circuit breaker 3.1, 3.2, from which the two series connections

(Strings) each of a circuit breaker 3.1, 3.2 and a disconnector 16.1, 17.1 are given. Only the

Input IN2, starting from the node on the first connection side 8 of the two circuit breakers 3.1, 3.2, can be disconnected via a single second disconnector 17.1. Now there is also a desire to equip the second input IN2 with a series connection of a circuit breaker and a disconnector so that, starting from a node on the respective first connection side of the circuit breakers 3.1, 3.2, 3.3, three strings continue, each with a circuit breaker 3.1, 3.2, 3.3 and an isolating switch 16.1, 17.1, 18.1 have been electrically connected in series, so that strings of the same structure can be used continuously from the node on the respective first connection side 8.

Correspondingly, the seventh embodiment variant is shown in Figures 12 and 13, which has three strands starting from a node, which have a circuit breaker 3.1, 3.2, 3.3 and a disconnector 16.1, 17.1, to each of the inputs INI, IN2 and to the output OUT. 18.1. Analogous to the fourth variant embodiment, the use of separate earthing switches, each with a drivable earthing contact piece 29, is provided in order to individually earth the respective disconnectors 16.1, 17.1, 18.1 and thus also the cables connected to the cable connections 22. Furthermore, when the disconnectors 16.1, 17.1, 18.1 are switched on, the respective second

Connection sides 9 of the circuit breakers 3.1, 3.2, 3.3 are grounded. By switching on one of the circuit breakers 3.1, 3.2, 3.3, ground potential can also be transferred to the first connection side 8 (node).

Each of the three circuit breakers 3.1, 3.2, 3.3 has a circuit breaker encapsulation section 4.1, 4.2, 4.3. The circuit breakers 3.1, 3.2, 3.3 and the circuit breaker encapsulation sections 4.1, 4.2, 4.3 each have a similar structure. On the second circuit breaker encapsulation section 4.2, a first connection flange 10 is arranged on the casing side at the level of the second connection side 9. The first disconnector enclosure section 13.1 is connected to the second via the first connection flange 10 Circuit breaker enclosure section 4.2 connected. On the first circuit breaker encapsulation section 4.1, a second connection flange 11 is arranged on the jacket side at the level of the second connection side 9 of the second circuit breaker 3.2. The second isolating switch enclosure section 14.1 is arranged on the second connection flange 11. A cable for forming an input INI can be connected to the associated cable connection 22 via the first isolating switch 16.1. A cable for forming a second input IN2 can be closed via a cable connection 22 via the second isolating switch 17.1. The two cable connections 22 are aligned in the same sense. A third power switch enclosure section 4.3 is arranged between the first power switch enclosure section 4.1 and the second power switch enclosure section 4.2. The third circuit breaker encapsulation section 4.3 is arranged parallel to the vertical axis of the first circuit breaker encapsulation section 4.1 and the second circuit breaker encapsulation section 4.2, so that the circuit breaker encapsulation sections 4.1, 4.2, 4.3 are arranged upright essentially parallel. For the mechanical connection of the circuit breaker capsule sections 4.1, 4.2, 4.3 the first connection flange 10 and the second connection flange 11 are provided diametrically opposite coupling flanges 28. The coupling flanges 28 are aligned with the first and the first connection flange 10, 11, with corresponding counter flanges on the third circuit breaker enclosure section 4.3, which enable a connection with the coupling flanges 28, due to the similar design. Shell side facing the central third circuit breaker capsule section 4.3, further coupling flanges 28 are arranged on the first circuit breaker capsule section 4.1 and the second circuit breaker capsule section 4.2, which are flanged to corresponding counter flanges. These coupling flanges 28, which are located on the first connection side 8 of the circuit breakers 3.1, 3.2, 3.3, are penetrated by a phase conductor section, so that the first Connection sides 8 of the circuit breakers 3.1, 3.2, 3.3

are electrically connected to each other (nodes). Starting from the node, a line is formed via the second circuit breaker 3.2 and the first disconnector 16.1 to the cable at the first input INI. Similarly, starting from the node via the first circuit breaker 3.1 and the second disconnector 17.1, a line to the second input IN2 or the cable located there is formed.

In order to form a third strand with the third circuit breaker 3.3, to which a third disconnector 18.1 is connected, the arrangement of a third disconnector terkapselungsabschnitts 15.1 is provided on the end of the third circuit breaker enclosure 4.3. On the front side, the positioning of a mating contact for the is on the second connection side 9 of the third circuit breaker 3.3

Disconnector contact piece of the third disconnector 18.1 is provided, the arrangement of a cable connector 22 being provided on the opposite end of the third disconnector enclosure section 15.1 in order to be able to connect a cable for the output OUT. In contrast to the structure of the first disconnector 16.1 and the second disconnector 17.1, the third disconnector 18.1 is designed in such a way that the connection sides of the third disconnector 18.1 lie on opposite end faces of the third disconnector encapsulation section 15.1 and thus no angular design for the third disconnector 18.1 according to the seventh Execution variant is available.

The functional assemblies shown in the individual figures are interchangeable with one another in terms of their structural design (e.g. circuit breaker, circuit breaker encapsulation section, disconnector encapsulation section, disconnector, disconnector contact piece, earthing switch, cable connection, etc.), so that, for example, combinations arise that include both three-position devices for the disconnectors as well as disconnectors with separate earthing switches etc. enable. Furthermore, the cable connections can also be changed from cable connections with inner cones and with cable connections with outer cones, etc.
