FIELD OF THE INVENTION
The invention relates to an electrical switching device arrangement having a
switching section which has at least one first and one second switching point,
which are electrically connected in series with one another by means of a
conductor section.
BACKGROUND OF THE INVENTION
An electrical switching device arrangement such as this is described, for
example, in the book "Schaltgerate Grundlagen, Aufbau, Wirkungsweise",
[Principles of Switching Devices, Design Method of Operation], published by
Manfred Lindmayer, Springer-Verlag Berlin, Heidelberg, New York, London, Paris,
Tokyo 1987, on pages 208 to 210. The switching device arrangement there has
four switching sections, two of which are each supported by a separate
supporting insulator. Two switching sections which are supported by different
supporting insulators have mutually facing ends. In order to connect the
mutually facing switching sections in series, they are electrically conductively
connected by means of a conductor section.
During use of the electrical switching device arrangement, external influences,
for example wind, earthquakes, or else switching processes themselves, lead for
example to oscillations of the electrical switching device arrangement.
The previously used connection of the switching points restricts the capability of
the electrical switching device arrangement to oscillate.

GB734035 discloses improved electric switches. According to this improvement, a
movable contact of a switch is connected to a fixed terminal member by a
longitudinally contractible conducting member carried by a rigid insulating
support and comprising a zig-zag structure built up of two or more toggle
sections whereof at least the hinges are each formed by a number of superposed
flexible conducting strips having their adjacent ends mechanically secured
together as by blocks. The sections are joined so that the longest strip in one
section faces the opposite way to the longest strip in the next section. The blocks
may be grooved at to receive pins when adjacent blocks are secured together as
by fish plates bolted to threaded boles. Blocks having flanges may be directly
secured together by bolts. In an alternative construction the strips may be
continuous from one section to the next, being gripped together at certain points
so that the shortest strip in one section becomes the longest in the next and vice
versa. The conducting member may be mounted between two insulating rods
having longitudinal grooves which act as guides for projecting portions of pins
when the member is caused to contract or expand.
US4533798 describes a high-current shunt for carrying current between relatively
fixed and movable terminals in a mechanism for controlling the transfer of
electrical energy. In one embodiment a plurality of generally oval, flexible,
ribbon-like electrical conductors are used to bridge the gap between two spaced
apart coaxial base members. Each ribbon-like conductor is suspended between
the two base elements so as to have a generally U-shaped configuration. By
connecting the conductors to each base element at a single point, the two base
elements may be rotated relative to each other to a limited degree. Stacking and
nesting of the ribbon conductors increases the current carrying capability. Good
electrical contact is established within a relatively small volume and relatively
little force is required to rotate the two elements relative to each other.

OBJECT OF THE INVENTION
The object of the invention is therefore to develop an electrical switching device
arrangement of the type mentioned initially such that the switch arrangement
can oscillate better.
SUMMARY OF THE INVENTION
In the case of an electrical switching device arrangement of the type mentioned
initially, the object is achieved according to the invention in that the conductor
section has at least one first and one second very flexible conductor element,
each of whose ends are attached to contact-making points of the first
and of the second switching point, with the stretched length of the conductor
elements being greater than a distance which runs along a straight line between
the contact-making points, and with a rigid connection element connecting the
flexible conductor elements to one another.
The use of very flexible conductor elements, for example of a cable or a chain
composed of links of electrically conductive material, such as copper, makes it
possible to easily compensate for relative oscillation of the first and second
switching sections of the electrical switching device arrangement with respect to
one another. The choice of increased stretched length reduces the mechanical
load on the very flexible conductor elements, thus ensuring a permanent
electrically conductive connection. The use of the rigid connection element for
the flexible conductor elements allows the movement of the conductor elements
with respect to one another to be restricted. This restricts the flexibility of the
individual conductor elements themselves, since they are supported with respect
to one another via the connection element.
In this case, it is advantageously possible to provide for the rigid connection
element to be supported by the very flexible conductor elements.

The use of the very flexible conductor elements as supporting
elements for the rigid connection element means that there is
no need to install additional holding apparatuses. This would
represent an additional load on the electrical switching device
arrangement. The this case, it is particularly advantageous for
the rigid connection element to be supported exclusively by the
very flexible conductor elements. Projections and edges on
electrical switching device arrangements are dielectrically
shielded by field control elements. The connection element and
the conductor elements may be located entirely within the area
of protection of the previously used field control elements.
A further advantageous development makes it possible to provide
for the rigid connection element to guide the very flexible
conductor elements parallel to one another.
Parallel guidance of a plurality of conductor elements results
in the conductor elements being stabilized with respect to one
another. On the basis of the parallel mounting of the conductor
elements on the connection element itself, the very flexible
conductor elements can be continued in different directions
from the attachment points to the rigid connection element.
This makes it possible to produce further arrangements which
reinforce the stability of the conductor sections with respect
to one another.
In this case, it is also advantageously possible to provide for
the conductor elements each to be bent through more than 45°,
in particular through 90°, starting from the parallel guidance
on the connection element, towards the contact-making points.
After emerging from the rigid connection element, the very
flexible conductor elements are still aligned parallel to one
another, at least immediately after leaving the rigid

connection element. Obtuse-angled bending allows the conductor
elements to run along a three-dimensional path which has at
least one elongated curvature. The curvature results in
compensation areas, which make it possible to compensate for
any relative movement between the first and the second
switching point.
In this case, the conductor elements may be shaped such that
they are arranged laid on a path on one plane. However, they
may also be laid with bends of angles through more than 45°,
and in particular through 90°.
A further advantageous development makes it possible to provide
for the connection element to fix the very flexible conductor
elements on a plane with respect to one another.
The arrangement of the very flexible conductor elements on a
plane on the connection element makes it possible to support
bulging or bending in a specific direction in the event of the
position of the switching points changing with respect to one
another. A plurality of conductor elements are therefore
arranged such that they lie flat alongside one another. This
results in a flat ribbon arrangement. It is therefore possible
to assist preferred deflection movements.
A further advantageous development makes it possible to provide
for at least one very flexible conductor element to be guided
in a U-shape.
A U-shaped position can be produced by using the force of
gravity when choosing suitable contact-making points with
appropriate feeding of the ends of the very flexible conductor
elements to the contact-making points. The rigid connection
element can then be mounted in a simple manner in the bottom
area of the U. In this case, it is either possible to provide

for a very flexible conductor element to pass completely
through the rigid connection element, or for the rigid
connection element to be used as a stop for the very flexible
conductor elements, with a U-shaped or else some other laid
shape being produced only on attachment of a plurality of
conductor elements. The use of a continuous very flexible
conductor element has the advantage that there is no need for
additional contact points, which would increase the electrical
impedance. The rigid connection element can electrically
isolate the plurality of very flexible conductor elements from
one another, or else can electrically conductively connect
them. The use of a plurality of conductor elements which allow
connection of the contact-making points only after they have
been coupled via the rigid connection element has an advantage
because it is possible to use short sections of conductor
elements which can be combined as required and can make contact
with one another via the rigid connection element. This
simplifies assembly.
A further advantageous development makes it possible to provide
for at least one very flexible conductor element to be guided
in an S-shape.
S-shaped guidance of one of the very flexible conductor
elements represents a further suitable shape to positively
influence the oscillation behavior of an electrical switching
device arrangement. It is particularly advantageous for a
plurality of very flexible conductor elements to be formed in
an S-shape and to be guided in opposite senses with respect to
one another. On a lateral projection, because of the rigid
coupling via the connection element, this results in the
conductor section connecting the two switching points having a
cruciform shape. A shape such as this is able to reliably
absorb oscillation movements acting in different directions. By

way of example, a cruciform shape such as this can also be
achieved by arranging two U-shaped very flexible conductor
elements with U-shapes pointing in opposite directions, and by
coupling them by means of a rigid connection element.
A further advantageous development makes it possible to provide
for the very flexible conductor elements to be guided in the
same way and to be arranged such that they are located one
behind the other, covering one another, on a projection.
An arrangement covering one another makes it possible to use a
multiplicity of identical very flexible conductor elements. The
physical space required is reduced by an arrangement such as
this. The arrangement of a plurality of conductor elements one
behind the other and covering one another in a viewing
direction results in the conductor section formed from a
plurality of very flexible conductor elements having a
structure like a flat ribbon.
It is advantageously also possible to provide for the very
flexible conductor elements to be arranged with mirror-image
symmetry with respect to one another on a projection.
An arrangement with mirror-image symmetry makes it possible
when using identical conductor elements and when they are laid
in an identical manner, for example in a U-shape or in an S-
shape, to produce additionally stabilizing shapes of the
conductor section. Zones which intersect one another, for
example, on the projection allow very flexible conductor
elements to be used with a particularly long extended length in
order to ensure that the electrical switching device
arrangement can oscillate well. Despite the long extended
lengths, the conductor section has adequate

mechanical stability because of a rigid connection element, thus preventing
uncoordinated oscillation or swinging of the very flexible conductor elements
which form a part of the conductor section.

DETAIL DESCRIPTION OF THE INVENTION
Figure 1 shows a side view of an electrical switching device arrangement 1,
partially cut away. The electrical switching device arrangement 1 has a switching

section 2 which is formed from a first switching point 2a, a
second switching point 2b, a third switching point 2c and a
fourth switching point 2d. The switching points 2a, 2b, 2c, 2d
are electrically connected in series with one another. This is
advantageous particularly for high and very high voltages, for
example for voltages of more than 480 kV, in order to ensure
that the switching section 2 has an adequate withstand voltage.
Two of the switching points 2a, 2d; 2b, 2c are respectively
supported by a supporting insulator 3a, 3b. The switching
points 2a, 2b, 2c, 2d are operated by a common drive device 4.
Any movement produced by the drive device 4 is transmitted
within the supporting insulators 3a, 3b to the movable contact
elements of the switching points 2a, 2b, 2c, 2d.
The switching points 2a, 2b, 2c, 2d are each arranged within
encapsulating housings 6a, 6b. The encapsulating housings 6a,
6b are manufactured in the present exemplary embodiment from
insulating material, so that the electrical switching device
arrangement 1 is a so-called live-tank switch. The interior of
the encapsulation housings 6a, 6b is in each case filled with a
pressurized insulating gas, for example sulfurhexafluoride,
nitrogen or mixtures of gases such as these. The mutually
facing ends of the first and second switching points 2a, 2b are
electrically conductively connected to one another by means of
a conductor section 5. Connection options for electrical power
transmission devices, such as lines or cables, are in each case
arranged at the mutually averted ends of the third and fourth
switching points 2c, 2d.
Figures 2, 3, 4, 5 and 6 illustrate the various development
variants of the conductor section 5.

Figures 2, 3, 4, 5 and 6 each show the mutually facing ends of
the first and second switching points 2a, 2b. The encapsulating
housings 6a, 6b which surround the switching points 2a, 2b are
essentially designed to be hollow and cylindrical, and are
closed in a gas-tight manner at the end faces of the fitting
bodies 7a, 7b. The fitting bodies 7a, 7b are manufactured from
an electrically conductive material and are part of the current
path which can be switched by means of the switching section 2.
The fitting bodies 7a, 7b which are associated with the
respective housings 6a, 6b are electrically conductively
connected to the respective first and second switching points
2a, 2b. The fitting bodies 7a, 7b have respective connecting
terminals 8a, 8b. The connecting terminals 8a, 8b are each
formed from half-shells, between which an electrical conductor
can be clamped in by the application of external clamping
forces, and can have electrical contact made with it. Clamping-
in holders for the connecting terminals 8a, 8b have an
essentially cylindrical shape, into which a conductor element
provided with a cylindrical external contour can be inserted.
The connecting terminals 8a, 8b represent contact-making
points. The position of the clamping-in holders in the
connecting terminals 8a, 8b is chosen such that their axial
alignment, which is governed by the cylindrical shape, is
arranged transversely with respect to an axis running between
the first and the second switching point to 2a, 2b. A first
very flexible conductor element 9 is inserted into and braced
in the fitting bodies 8a, 8b. The very flexible conductor
element 9 is in the form of an electrically conductive cable,
with the ends of the conductor element 9 each being inserted
from the same direction into the clamping-in holders of the
connecting terminals 8a, 8b. In consequence, the very flexible
conductor element 9 is U-shaped.
A rigid connection element 10 is arranged in the central area
of the very flexible conductor element 9. The rigid connection

element 10 is used to couple a plurality of very flexible
conductor elements.

which are located one behind the other, covering one another,
in the present exemplary embodiment, and are arranged
identically, at a rigid angle.
By way of example, figure 7 shows a rigid connection element
10. The rigid connection element 10 has a first half-shell 10a
and a second half-shell 10b, which can be pressed onto one
another. In the contact area between two surfaces of the half-
shells 10a, 10b, cylindrical recesses are formed, into which
very flexible conductor elements can be inserted, so that they
are guided parallel in the area of the rigid connection element
10. The sizes of the recesses are in this case chosen such that
the very flexible conductor elements are braced in the rigid
connection element 10 so the two half-shells 10a, 10b are
pressed together. In the present example, the rigid connection
element 10 which is illustrated in figure 7 is used to couple
three very flexible conductor elements.
The rigid connection element 10 may be designed such that it
allows electrical contact to be made with the very flexible
conductor elements 9 which have been inserted into the
recesses. However, it can also be designed so as to allow the
very flexible conductor elements 9, which are jointly
surrounded by the rigid connection element 10, to be held in an
insulated manner. Depending on the currents to be transmitted,
the number of very flexible conductor elements 9 which are
braced in one rigid connection element 10 may vary. The number
can be matched appropriately to the recess for holding the very
flexible conductor elements 9.
Since the first and the second switching point 2a, 2b, as well
as the encapsulating housings 6a, 6b, the fitting bodies 7a, 7b
and the connecting terminals 8a, 8b are in each case of
identical design,

only the conductor sections 5, which are designed differently
to one another, would in each case be explained in the
description of the following embodiment variants.
Figure 3 shows a conductor section 5 designed such that a first
very flexible conductor element 9a is laid in a U-shape, and a
second very flexible conductor element 9b is likewise laid in a
U-shape. However, the two very flexible conductor elements 9a,
9b are arranged with mirror-image symmetry with respect to one
another, with the mirror-image axis being arranged parallel to
an axis which extends between the switching points 2a, 2b. A
known form of connecting terminals 8a, 8b is in each case
provided for attachment of the first and of the second
respective very flexible conductor elements 9a, 9b, with the
connecting terminals 8a, 8b associated with the first very
flexible conductor element 9a in each case holding the very
flexible conductor element 9a, coming from the same direction.
The connecting terminals 8a, 8b which are associated with the
second very flexible conductor element 9b hold the ends of the
second very flexible conductor element 9b, likewise from the
same direction, with this running in the opposite direction
sense with respect to the insertion direction of the first very
flexible conductor element 9a to its associated connecting
terminals 8a, 8b (with mirror-image symmetry). A rigid
connection element 10 is once again provided in the central
area of the first and of the second very flexible conductor
element 9a, 9b and connects a plurality of conductor elements,
in the present case two conductor elements, to one another at a
rigid angle, one behind the other with respect to the plane of
the drawing. On the projection, this therefore results in a
cruciform conductor section 5 which is formed from
intrinsically very flexible conductor elements and, as a result
of being clamped in at the connecting terminals 8a, 8b and as a
result of the rigid connection element 10 and the way in which
the very flexible conductor elements 9a, 9b

are laid, this represents a comparatively rigid structure, but
which can compensate for oscillations.
The first and the second very flexible conductor elements 9a,
9b are guided approximately parallel to one another on a plane
on the rigid connection element 10. The first and the second
very flexible conductor elements 9a, 9b are also guided
approximately parallel in the immediate inlet and outlet area
of the rigid connection element 10. After emerging from the
rigid connection element 10, the very flexible conductor
elements 9a, 9b are each bent through 90°, with the conductor
elements 9a, 9b each being bent in the same direction,
therefore in each case resulting in a U-shaped profile.
However, it is also possible to use other angles which are in
each case greater than 45°. The individual sections of the very
flexible conductor elements can also be deflected such that the
conductor elements 9 can emerge from a plane as well, and can
extend into a space.
Figure 4 shows an alternative to the exemplary embodiment of a
conductor section 5 illustrated in figure 3. The conductor
section 5 is once again formed from a plurality of very
flexible conductor elements 9c, 9d. However, one development
variant of a rigid connection element 10 is designed such that,
on the projection shown in figure 4, there is no overlap
between the laying paths of the very flexible conductor
elements 9c, 9d, although they are designed with mirror-image
symmetry. When using exclusively two very flexible conductor
elements 9c, 9d these also lie on one and the same plane.
However, if provision is made for further very flexible
conductor elements to be located, covering one another, behind
the very flexible conductor elements 9c, 9d which can be seen
in figure 4, then the conductor elements run on two planes in
the area of the

rigid connection element 10a, with the planes being aligned
approximately parallel, but at a distance from one another.
Figure 5 shows a further development variant of a conductor
section 5, in which a further very flexible conductor element
9e is laid in an S-shape. For this purpose, the connecting
terminals 8a, 8b are separated from one another such that the
further very flexible conductor element 9e is in each case
introduced into the connecting terminals 8a, 8b from opposite
directions. A plurality of further very flexible conductor
elements 9e which are arranged located one behind the other,
covering one another, are coupled to one another by a rigid
connection element 10.
Figure 6 shows a development variant of the conductor section 5
illustrated in figure 5. A further very flexible conductor
element 9e and a very flexible conductor element 9f are each
bent in an S-shape and have an identical bent shape, but the
deflection directions of the S-curves are aligned in opposite
senses (with mirror-image symmetry), thus resulting in the
conductor elements 9e, 9f crossing over on a projection
illustrated in figure 6. These elements are stabilized in the
central area of a rigid connection element 10. This once again
results in a cruciform connection being formed between the
contacts of the first and of the second switching point 2a, 2b,
which can absorb oscillations with adequate mechanical
stability.
Sections of the very flexible conductor elements which run in a
curved shape, preferably bent through 90°, are in each case
formed between the individual connecting terminals and the
rigid connection element of the exemplary embodiments. Since a
direction change in the profile of a very flexible conductor
element in each case runs between two stabilizing clamping-in
points, this results in a conductor section with elastic

characteristics, which can absorb external oscillation
phenomena. Crossing and coincident conductor elements can
therefore advantageously support one another.
