Abstract
In a polyphase encapsulated outdoor high-voltage switching device, the circuit breakers are arranged horizontally in a tubular switch enclosure which is provided at the ends with connecting flanges for connection of further encapsulation modules. Such encapsulation modules are, in particular, direction-changing modules, by means of which the directions of the electrical connections of the interrupter units of the circuit breaker are changed into branching cable connections. These encapsulation modules may, in particular, be angled splitting modules with associated outdoor bushings, and disconnector-grounding device modules. When using direction-changing modules which change the direction of the current path horizontally through 90.degree., H-circuits can be produced such that all the modules are arranged in a horizontal plane. The switching device thus has little physical height.
Description
Polyphase encapsulated outdoor high-voltage switching device Technical Field The invention relates to the field of electrical power distribution and can be used for the design configuration of a polyphase encapsulated, gas-insulated outdoor high-voltage switching device, in which a switch enclosure which accommodates the circuit breaker interrupter units and is arranged flat or horizontally has associated with it, at both ends, line connections which branch off at an angle to the longitudinal axis of the switch enclosure. These line connections may be outdoor bushings, cable connections or busbar connections.
Background in a xxnown high-voltage switching device of this type, the interrupter u:nits are arranged in a tubular enclosure which can be split centrally and is provided in the region of its ends with sleeves which run transversely with respect to the enclosure axis;
each sleeve accommodates an outgoer which is connected to the appropriate pole of an interrupter unit. A piece of tubing is also connected to each sleeve, and a switch disconnector and, possibly, a grounding switch, is arranged in each piece of tubing. A current transformer is arranged around each of the sleeves. A
voltage transformer can also be provided between the sleeves and the adjacent pieces of tubing. Finally, a cable termination is intended to be fit to the end of each piece of tubing, as an outdoor bushing. These cable terminations form an essential part of the feeders and outgoers, and include an acute angle between then. - In this high-voltage switching device, the switch enclosure is sealed at one of its end faces by a mounting cover, while the drive for the moveable parts of the interrupter units is arranged at the opposite end. The drive device is in this case also fixed on a frame, on which the switch enclosure also rests (European Patent Office Application (publication) EP 0 744 758 A2 published 27 November 1996).
For single-phase encapsulated outdoor high-voltage switching devices, an arrangement is known in which a tubular encapsulation enclosure, which is arranged horizontally and contains an interrupter unit for a circuit breaker, has associated with it at each of its two ends an outdoor bushing which is arranged on a separate foundation, and in which, for connection of the respective outdoor bushing, a further encapsulation enclosure, which runs obliquely with respect to the axis of the encapsulation enclosure, is arranged at each of the ends on the encapsulation enclosure.

Summary of the Invention Against the background of a polyphase ~ encapsulated, gas-insulated outdoor high-voltage switching device, embodiments of the invention are based on the object of designing the switching device to be variable, and in this case to ensure that it has as little physical height as possible.
Accordingly, in one aspect of the present invention, there is provided a polyphase encapsulating, gas-insulated outdoor high-voltage switching device with a flat or horizontal construction, in which a number of circuit breaker interrupter units are arranged parallel to one another in a tubular switch enclosure, in which, at both ends, these interrupter units have associated electrical connections which branch off at an angle to the longitudinal axis of the switch enclosure, and in which the switch enclosure is arranged on a mounting frame and the switch enclosure has an associated drive device for driving moveable parts of the interrupter units, wherein the drive device is arranged to the side of the switch enclosure, via a rotary bearing which is arranged in the casing region of the switch enclosure, in order to introduce the drive forces into the switch enclosure, and wherein the switch enclosure is provided at the ends with connecting flanges for connection of encapsulation modules, in which case at least two encapsulation modules are arranged as further encapsulation modules in order to change the direction of electrical connections of the interrupter units into branching line connections.
Another aspect of the invention provides that the drive device is arranged to the side of the switch enclosure, via a rotary bearing which is arranged in the 3a casing region of the switch enclosure, in order to introduce the drive forces into the switch enclosure, and in that the switch enclosure is provided at the ends with connecting flanges for connection of further encapsulation modules, in which case at least two modules are arranged as further encapsulation modules in order to change the direction of the electrical connections of the interrupter units into the branching line connections.
This refinement of the switching device thus essentially provides for the tubular shape of the switch enclosure to be modified as little as possible and for the rest of the components associated with the switching device to have individual encapsulation modules associated with them, which are connected to the switch enclosure at the ends, in the horizontal direction. To this end, it may be expedient to split the switch enclosure asymmetrically and transversely, in which case the external diameters of the connecting flanges of the switch enclosure are less than the external diameter of the switch enclosure. This, for example, opens up the possibility of the axially shorter part of the switch enclosure also being in the form of a current transformer module, which is known in principle. In addition, a further current transformer can be integrated in the switch enclosure, at its other end. However, the switch enclosure can also be split transversely in such a manner that two axially shorter parts are associated with both ends with one axially longer part, with the external diameter of the connection flanges for connection of further encapsulation modules being less than the external diameter of the switch enclosure, and in that at least one of the axially shorter parts of the switch enclosure is in the form of a current transformer module.
The central feature for the invention is that two modules are generally provided as further encapsulation modules and are used to change the direction of the electrical connections of the circuit breaker poles into the line connections which branch off at an angle. These direction-changing modules can in this case contain combined disconnector-grounding switches in a manner known per se.
In addition, a cable connection module or a tubular encapsulation module of a horizontally running three-phase busbar can be connected to the direction-changing modules;
at least one of the two direction-changing modules may also be in the form of a splitting module with connections, which branch off upwards in a spread manner, for outdoor bushings.
In this case, a splitting module with connections which branch off upwards in a spread manner for outdoor bushings can be fit to the second direction-changing module. This is particularly worthwhile if it is also intended to connect a fast-action grounding device module to the direction-changing modules. The association between the differently designed or differently fitted direction-changing modules and the two ends of the tubular switch enclosure may be configured as required. One arrangement which is particularly expedient for practical requirements is for a vertically aligned direction-changing module, which is in the form of a disconnector-grounding device module, to be arranged at each of the two ends of the switch enclosure, and for a splitting module having connections which branch off upwards in a spread manner for outdoor bushings to be fit to each direction-changing module, with the outdoor connections of the respective splitting module lying in a 5 common plane, which is inclined to the vertical. Such a switchgear assembly can provide a space-saving replacement for switchgear assemblies which in the past have been constructed in covered rooms from components of previously normal outdoor switchgear assemblies which were not encapsulated. The novel switchgear assembly can also be used in a simple manner to provide a simple busbar, running in two planes arranged one above the other, with a circuit breaker longitudinal coupling. In this case, a tubular encapsulation module of a horizontally running section of the three-phase busbar is then connected to the one direction-changing module of the switching device, and a further identical direction-changing module is connected to the other, vertically aligned direction-changing module, adjacent to it and above it, and is then used for coupling the second, second busbar section which runs physically parallel to the first busbar section, expediently via an encapsulation tube which runs parallel to the switching device, and an adjacent direction-changing module.
If the direction-changing modules are in the form of splitting modules with connections which branch off upwards in a spread manner for outdoor bushings, then the splitting modules can be designed such that the outdoor bushings lie in a common vertical plane. In this case, it is recommended that the splitting module be designed on the basis of an arrangement which is known, such that each angled splitting module is in the form of a short hollow Sa cylinder, from which an enclosure region which widens in the form of a funnel branches off radially and merges into three connecting flanges, with the connecting planes of these connecting flanges resting tangentially against a part of a circle which runs concentrically with respect to the axis of the splitting module. - However, the connecting flanges may also be arranged such that the outdoor bushings do not lie in a common plane, but are spread apart in different directions in such a manner that the free ends of the outdoor bushings are at the same height.
The arrangement of further encapsulation modules in addition to the direction-r.hanging modules is also feasible for integration of voltage transformer modules in addition to integration of switch disconnectors and grounding switches and combined switch disconnector grounding switches. A disconnector module or a disconnector-grounding device module can be arranged on one side or both sides of the switch enclosure, between a connection flange of the switch enclosure and an angled direction-changing module. A
voltage transformer module is then expediently radially connected to the disconnector module or to the disconnector-grounding device module. Three-phase dielectric bushings, which may also be compartmentalized, are also expediently integrated in the last-mentioned modules.
The arrangement of further encapsulation modules on the end faces of the switch enclosure provides the possibility for the switch drive to be arranged in a space-saving manner at the side of, or preferably underneath the switch enclosure. In this case, the switch drive is coupled to the moveable parts of the interrupter units via a rotary bearing which is arranged in the casing region of the switch enclosure as is normal, for example, for outdoor circuit breakers. To this end, the drive device is expediently mounted on a mounting flange in the casing region of the switch enclosure, and is coupled via separate lever drives for the individual interrupter units to their moveable contact pieces; in this case, the rotary bearing is then arranged in a drive housing connected to the mounting flange, while each lever drive has a two-armed direction-changing lever, whose rotary bearing is supported in an insulated manner on the casing of the switch enclosure. The switch enclosure can be provided with an additional mounting opening in its casing region.
The variability of the novel outdoor high-voltage switching device can be improved even further if further encapsulation modules are arranged between a connection flange of the switch enclosure and one of the two angled direction-changing modules, which are preferably in the form of splitting modules with connections which branch off upwards in a spread manner for outdoor bushings, at least one of which encapsulation modules is used to change the direction of the current path through 90 in a horizontal plane. This provides the possibility of upgrading the switching device in such a manner that two or more outdoor high-voltage switching devices can be arranged in what is referred to as an H-circuit. The further encapsulation modules are thus essentially disconnector-grounding device modules and additional circuit breaker modules. In particular, it is expedient to provide three disconnector-grounding device modules, which are arranged diagonally opposite one another at right angles, as further encapsulation modules, the central one of which is connected via an additional circuit breaker module to a second outdoor high-voltage switching device which has an identical construction and is arranged in mirror-image form. In this case, what is referred to as a cruciform module, as is normal for encapsulated, gas-insulated high-voltage switchgear assemblies, is expediently used as a module for 7a changing the direction of the current path through 90 in a horizontal plane, and which contains a three-phase combined switch disconnector/grounding switch as is known. In addition and specifically, a voltage transformer module can be flange-connected to this cruciform module.
A modification of the invention furthermore provides the possibility of flange-connecting the module for changing the direction of the current path through 90 in a horizontal plane axially to the angled splitting module rather than arranging it between the switch enclosure and one of the two angled splitting modules.
The refinement of the outdoor high-voltage switching device provided according to the invention also allows a switching device designed in a corresponding manner to be used either as a longitudinal coupling for coupling transformers in the course of an overhead line or a gas-insulated busbar, or as a transverse coupling for feeding a double overhead line system into a transformer station.

Detailed Description Figures 1 and 2 show an outdoor high-voltage switching device in which a switch enclosure 1 is arranged lying horizontally on a frame 2. The switch enclosure 1 is split transversely and asymmetrically, thus resulting in a longer enclosure part 11 and a shorter enclosure part 12.
The two enclosure parts are provided with a respective connecting flange 13 or 14, with the external diameter (d) of the respective connecting flange being less than the external diameter (D) of the switch enclosure 1. Three 9a interrupter units are arranged, preferably diagonally opposite, in the switch enclosure in a manner which is not illustrated. The switch enclosure may be oval, if required.
The enclosure part 12 may at the same time be used as an encapsulation module for accommodating a current transformer.
An encapsulation module is flange-connected to the 5 switch enclosure 1 or to its enclosure part 12, this encapsulation module 4 being an angled splitting module for changing the direction of the electrical connections of the circuit breaker poles into the outdoor bushings 45 which branch off in a spread manner. For this purpose, the 10 encapsulation module, which is in the form of a short hollow cylinder 41, merges into an enclosure region 42 which widens radially in the form of a funnel and ends in three connecting flanges 43. The connecting planes of these connecting flanges rest tangentially against a part of a circle 44, in which case this part of a circle is arranged concentrically with respect to the axis of the splitting module, and hence with respect to the axis 15 of the switch enclosure 1. In the illustrated embodiment, the outdoor bushings 45 lie jointly in a vertical plane.
A second angled splitting module 4 is arranged at the other end of the high-voltage switching device. An encapsulation module 5 is located between this second splitting module 4 and the connecting flange 13 of the enclosure part 11 and accommodates a combined switch disconnector/grounding switch, which is not illustrated in any more detail, in a known manner. Such a switch is known in principle. The encapsulation module 5 also has a radially arranged connecting flange 51, to which a voltage transformer 6 is flange-connected. An identical encapsulation module 5 can also be arranged between the enclosure part 12 and the associated angled splitting module 4. In the simplest case, the high-voltage switching device essentially comprises only the switch enclosure 1 which l0a accommodates the circuit breaker interrupter units, and two splitting modules 4 which are flange-connected at the side.
A housing 3 is also arranged underneath the switch enclosure 1, is mounted on the frame 2 and, in addition to the switch and assembly controller, accommodates a drive device, which is not shown in any more detail, for driving the moveable parts of the interrupter units which are arranged in the switch enclosure 1. For this purpose, parts of a lever drive are articulated on the moveable parts of the interrupter units through the casing of the switch enclosure 1, or through a flange arranged in the casing region.
Figure 3 shows a circuit breaker module 25 whose switch enclosure is split transversely in such a manner that two axially shorter enclosure parts 15 and 16 are associated with an axially longer part 17. The enclosure parts 15 and 16 have an identical construction and are used, inter alia, as current transformer modules, of which the secondary connecting region 76 can in each case be seen. The enclosure parts 15 and 16 are also used as adapters between the tubular enclosure part 17 and the adjacent encapsulation modules, in which case the connection flange facing the enclosure part 17 has a larger external diameter than the connection flange associated with the adjacent encapsulation module.
The poles 26 and 27 of one of the three circuit breaker poles are indicated in outline form within the enclosure part 17, with each circuit breaker pole being supported on the tubular enclosure wall of the enclosure part 17 via a respective hollow insulating support 28 or 29. For this purpose, the pole 26 has an associated traverse 77 in the region of an enclosure flange 18. An enclosure 19 is flange-connected to the enclosure flange 18, accommodates a direction-changing drive and, as shown in Figure 4, is at the same time provided with a supporting flange 34 for a drive device 35. The drive device 35 contains a spring energy-storage drive 36, which acts on a direction-changing lever 39 via a direction-changing lever 37 and a coupling rod 38. The rotary bearing of this direction-changing lever is mounted in the enclosure 19 in such a manner that one of its lever - 11a -arms is located inside the enclosure 19. A vertically moveable coupling rod 70 is articulated on this lever arm. On each of the circuit breaker poles which are provided in the switch enclosure 17 ~....~..-_.~..M,.~..~........_..~.._ õ ~.~..._.....~... .____._,....~.._..
Accordingly, in one aspect of the present invention, there is provided a polyphase encapsulating, gas-insulated outdoor high-voltage switching device with a flat or horizontal construction, in which a number of circuit breaker interrupter units are arranged parallel to one another in a tubular switch enclosure, in which, at both ends, these interrupter units have associated electrical connections which branch off at an angle to the longitudinal axis of the switch enclosure, and in which the switch enclosure is arranged on a mounting frame and the switch enclosure has an associated drive device for driving moveable parts of the interrupter units, wherein the drive device is arranged to the side of the switch enclosure, via a rotary bearing which is arranged in the casing region of the switch enclosure, in order to introduce the drive forces into the switch enclosure, and wherein the switch enclosure is provided at the ends with connecting flanges for connection of encapsulation modules, in which case at least two encapsulation modules are arranged as further encapsulation modules in order to change the direction of electrical connections of the interrupter units into branching line connections.
Another aspect of the invention provides that the drive device is arranged to the side of the switch enclosure, via a rotary bearing which is arranged in the 3a casing region of the switch enclosure, in order to introduce the drive forces into the switch enclosure, and in that the switch enclosure is provided at the ends with connecting flanges for connection of further encapsulation modules, in which case at least two modules are arranged as further encapsulation modules in order to change the direction of the electrical connections of the interrupter units into the branching line connections.
This refinement of the switching device thus essentially provides for the tubular shape of the switch enclosure to be modified as little as possible and for the rest of the components associated with the switching device to have individual encapsulation modules associated with them, which are connected to the switch enclosure at the ends, in the horizontal direction. To this end, it may be expedient to split the switch enclosure asymmetrically and transversely, in which case the external diameters of the connecting flanges of the switch enclosure are less than the external diameter of the switch enclosure. This, for example, opens up the possibility of the axially shorter part of the switch enclosure also being in the form of a current transformer module, which is known in principle. In addition, a further current transformer can be integrated in the switch enclosure, at its other end. However, the switch enclosure can also be split transversely in such a manner that two axially shorter parts are associated with both ends with one axially longer part, with the external diameter of the connection flanges for connection of further encapsulation modules being less than the external diameter of the switch enclosure, and in that at least one of the axially shorter parts of the switch enclosure is in the form of a current transformer module.
The central feature for the invention is that two modules are generally provided as further encapsulation modules and are used to change the direction of the electrical connections of the circuit breaker poles into the line connections which branch off at an angle. These direction-changing modules can in this case contain combined disconnector-grounding switches in a manner known per se.
In addition, a cable connection module or a tubular encapsulation module of a horizontally running three-phase busbar can be connected to the direction-changing modules;
at least one of the two direction-changing modules may also be in the form of a splitting module with connections, which branch off upwards in a spread manner, for outdoor bushings.
In this case, a splitting module with connections which branch off upwards in a spread manner for outdoor bushings can be fit to the second direction-changing module. This is particularly worthwhile if it is also intended to connect a fast-action grounding device module to the direction-changing modules. The association between the differently designed or differently fitted direction-changing modules and the two ends of the tubular switch enclosure may be configured as required. One arrangement which is particularly expedient for practical requirements is for a vertically aligned direction-changing module, which is in the form of a disconnector-grounding device module, to be arranged at each of the two ends of the switch enclosure, and for a splitting module having connections which branch off upwards in a spread manner for outdoor bushings to be fit to each direction-changing module, with the outdoor connections of the respective splitting module lying in a 5 common plane, which is inclined to the vertical. Such a switchgear assembly can provide a space-saving replacement for switchgear assemblies which in the past have been constructed in covered rooms from components of previously normal outdoor switchgear assemblies which were not encapsulated. The novel switchgear assembly can also be used in a simple manner to provide a simple busbar, running in two planes arranged one above the other, with a circuit breaker longitudinal coupling. In this case, a tubular encapsulation module of a horizontally running section of the three-phase busbar is then connected to the one direction-changing module of the switching device, and a further identical direction-changing module is connected to the other, vertically aligned direction-changing module, adjacent to it and above it, and is then used for coupling the second, second busbar section which runs physically parallel to the first busbar section, expediently via an encapsulation tube which runs parallel to the switching device, and an adjacent direction-changing module.
If the direction-changing modules are in the form of splitting modules with connections which branch off upwards in a spread manner for outdoor bushings, then the splitting modules can be designed such that the outdoor bushings lie in a common vertical plane. In this case, it is recommended that the splitting module be designed on the basis of an arrangement which is known, such that each angled splitting module is in the form of a short hollow Sa cylinder, from which an enclosure region which widens in the form of a funnel branches off radially and merges into three connecting flanges, with the connecting planes of these connecting flanges resting tangentially against a part of a circle which runs concentrically with respect to the axis of the splitting module. - However, the connecting flanges may also be arranged such that the outdoor bushings do not lie in a common plane, but are spread apart in different directions in such a manner that the free ends of the outdoor bushings are at the same height.
The arrangement of further encapsulation modules in addition to the direction-r.hanging modules is also feasible for integration of voltage transformer modules in addition to integration of switch disconnectors and grounding switches and combined switch disconnector grounding switches. A disconnector module or a disconnector-grounding device module can be arranged on one side or both sides of the switch enclosure, between a connection flange of the switch enclosure and an angled direction-changing module. A
voltage transformer module is then expediently radially connected to the disconnector module or to the disconnector-grounding device module. Three-phase dielectric bushings, which may also be compartmentalized, are also expediently integrated in the last-mentioned modules.
The arrangement of further encapsulation modules on the end faces of the switch enclosure provides the possibility for the switch drive to be arranged in a space-saving manner at the side of, or preferably underneath the switch enclosure.

Detailed Description Figures 1 and 2 show an outdoor high-voltage switching device in which a switch enclosure 1 is arranged lying horizontally on a frame 2. The switch enclosure 1 is split transversely and asymmetrically, thus resulting in a longer enclosure part 11 and a shorter enclosure part 12.
The two enclosure parts are provided with a respective connecting flange 13 or 14, with the external diameter (d) of the respective connecting flange being less than the external diameter (D) of the switch enclosure 1. Three 9a interrupter units are arranged, preferably diagonally opposite, in the switch enclosure in a manner which is not illustrated. The switch enclosure may be oval, if required.
The enclosure part 12 may at the same time be used as an encapsulation module for accommodating a current transformer.
An encapsulation module is flange-connected to the 5 switch enclosure 1 or to its enclosure part 12, this encapsulation module 4 being an angled splitting module for changing the direction of the electrical connections of the circuit breaker poles into the outdoor bushings 45 which branch off in a spread manner. For this purpose, the 10 encapsulation module, which is in the form of a short hollow cylinder 41, merges into an enclosure region 42 which widens radially in the form of a funnel and ends in three connecting flanges 43. The connecting planes of these connecting flanges rest tangentially against a part of a circle 44, in which case this part of a circle is arranged concentrically with respect to the axis of the splitting module, and hence with respect to the axis 15 of the switch enclosure 1. In the illustrated embodiment, the outdoor bushings 45 lie jointly in a vertical plane.
A second angled splitting module 4 is arranged at the other end of the high-voltage switching device. An encapsulation module 5 is located between this second splitting module 4 and the connecting flange 13 of the enclosure part 11 and accommodates a combined switch disconnector/grounding switch, which is not illustrated in any more detail, in a known manner.

The drive device 35 contains a spring energy-storage drive 36, which acts on a direction-changing lever 39 via a direction-changing lever 37 and a coupling rod 38. The rotary bearing of this direction-changing lever is mounted in the enclosure 19 in such a manner that one of its lever - 11a -arms is located inside the enclosure 19. A vertically moveable coupling rod 70 is articulated on this lever arm.
