Full Text	Description Bus tie The invention- relates to a bus tie for switchgear assemblies for connection of two switch panels to an isolating arrangement which in each case contains a contact arrangement and a field control device which is connected to the contact arrangement. A bus tie such as this is known from DE 101 19 183 Cl. The bus tie disclosed there is intended for electrical connection of two switch panels and has an isolating arrangement comprising two bush elements and an isolating element between which a field control apparatus is arranged; the isolating arrangement contains a contact arrangement. In the case of this bus tie, a field control apparatus is provided in the form of a field control element which can be deformed elastically like rubber and extends axially over the entire length of a connecting element of the contact arrangement. This field control element overcomes possible air enclosures in the interior of the bus tie, in that the field control element is electrically connected to the contact elements. The object of the present invention is to specify a bus tie of the type mentioned initially, which can be produced at low cost and allows simple installation. According to the invention, this object is achieved, in that the isolating arrangement has a single separate isolating body with an embedded field control apparatus for each switch panel, and, in each separate isolating body, the field control apparatus contains at least one cylindrical control electrode which surrounds the contact arrangement and is electrically connected to it. An isolating arrangement such as this considerably simplifies the installation of the bus tie according to the invention, because the control electrodes of the field control apparatus are embedded in the isolating bodies in such a way that there is no need for complex and precise positioning of the field control apparatus during installation of the bus tie, with the control electrodes which are arranged in the isolating bodies ensuring an adequate decrease in the field within the isolating bodies, thus effectively preventing partial discharges in the interior. In addition, the bus tie according to the invention can be produced at comparatively low cost because it requires only isolating bodies of the same design in order to produce its isolating arrangement. In a further refinement of the invention, the field control apparatus has an opposing electrode, on the ground side, which surrounds the cylindrical control electrode. An opposing electrode such as this allows the field to be decreased in an advantageous manner within the isolating body. In one preferred embodiment, the opposing electrode is passed out of the isolating body and ends in an attachment flange. The attachment flanges allow the opposing electrodes to be grounded in a simple manner by attachment to housing parts of the switchgear assembly. In one expedient development a contact element of the contact arrangement is embedded in the respective separate isolating bodies, to which contact element the respective control electrode is electrically conductively connected. In an arrangement such as this, the potential- on the control electrodes is linked in a simple manner to the high-voltage potential of the contact elements, thus allowing the field in the isolating body to be decreased. In a further refinement, the control electrodes are toroidal at their ends facing the respective opposing electrode. A toroidal configuration is particularly advantageous for decreasing the field, because areas with corners or edges with a high field strength are avoided. In another preferred refinement, the control electrode projects so far into a free space which is intended to hold a connecting element of the contact arrangement, in the interior of the isolating arrangement that contact is made with the connecting element. This likewise forms a potential link, in a simple manner, between the control electrodes and those parts of the bus tie which carry potential, during installation of the bus tie, with the annular control electrode having adequate field control characteristics in order to decrease the field in the interior of the isolating bodies. In one expedient refinement, a seal is provided between the isolating bodies. A seal such as this, for example in the form of an earring or a sealing lip, provides protection in a simple manner for the interior of the bus tie against environmental influences. The invention will be explained in more detail in the following text using the drawing and one exemplary embodiment, and with reference to the attached figures, in which: Figure 1 shows one exemplary embodiment of a first embodiment of the bus tie according to the invention; Figure 2 shows a further exemplary embodiment of the bus tie according to the invention; and Figure 3 shows a perspective partial view of a bus tie according to the invention. Figure 1 shows a bus tie 1 for electrical connection of two switch panels 2, 3 in a switchgear assembly, for example a gas-insulated switchgear assembly. The bus tie 1 is in this case symmetrical with respect to its center axis A, with that part of the bus tie 1 which is associated with the switch panel 3, corresponding to the parts associated with the switch panel 2, being annotated with the same reference symbols but with an apostrophe. The bus tie 1 comprises an isolating arrangement 4, 4' with isolating bodies 4, 4', which are cast from casting resin and have a respective free space 5 or 5' . The respective free spaces 5 and 5' of the isolating bodies 4 and 4' in this case have a conical profile. Contact elements 6 and 6' , respectively, extend through the respective isolating body 4 and 4' and, at one end, each have a connecting hole with a respective internal thread 7 or 7' for connection to lines, which are not illustrated in the figures, of the switch panels 2 and 3. The contact elements 6, 6' are spherical at the respective end 8 or 8' opposite the connecting holes. A connecting part 9 which is formed from an electrically conductive material surrounds the spherical ends 8, 8' of the contact elements 7, 1' and thus forms a conductive connection between the contact elements 7 and 7'. The connecting part 9 will be explained in more detail with reference to Figure 3. Control electrodes 10, 10' are embedded in the respective isolating bodies 4 and 4', are conductively connected at one end by means of respective connecting webs 11 and 11' to the respective contact element 6 or 6' , and are toroidally curved in the direction of the free space 5 or 5' at their respective other end 12 and 12' . Opposing electrodes 13, 13' are encapsulated in the respective isolating bodies 4 and 4' and are passed out of the isolating bodies 4, 4' as flanges 14, 14'. The flanges 14, 14' are attached to housing walls, which are not illustrated in the figures, of the respective switch panels 2 and 3, for example by means of a screw connection, which is not illustrated in the figures, or by welding. The flanges 14, 14' are in this case at ground potential. The respective control electrodes 12 and 12' extend from the area of the respective connecting hole 7 or 7' of the contact elements 6, 6' in the axial direction over the connecting area between the connecting part 9 and the contact elements 6, 6' into the area of the opposing electrodes 13, 13' . This arrangement of the respective control electrodes 12 and 12', which are at the same potential as the respective live contact parts 6 and 6', via the connections 11 and 11', respectively, leads to an adequate decrease in the field in the interior of the isolating bodies 4, 4' and thus to avoidance of partial-discharge processes in the free spaces 5 and 5' , respectively. A seal 15 in the form of an earring or a sealing lip is provided in order to seal the bus tie against external environmental influences, and is illustrated by dashed lines in Figure 1. Figure 2 shows a further exemplary embodiment of a bus tie 21 according to the invention, with only one isolating body 4 of the bus tie 21 being illustrated in Figure 2. In contrast to the bus tie 1 shown in Figure 1, an annular control electrode 22 is provided in the bus tie 21, is encapsulated in the isolating body 4, and has a connecting area 23 which projects out of the isolating body 4 into the free space 5 of the isolating body 4, to be precise in such a way that, during installation of the bus tie 21, fitting of the connecting part 9, which is not illustrated in the figure in Figure 2, forms a conductive connection between the connecting part 9 and the connecting area 23 such that, this conductive connection keeps the control electrode 22 at the same potential as the contact elements 6. A control electrode such as this also ensures an adequate reduction in the field in the isolating body. Figure 3 shows a perspective illustration of an isolating body 4 of the bus tie with the flange 14 and the free space 5, with the connecting part 9 being mounted on the spherical end 8, which cannot be seen, of the contact element 6, which can likewise not be seen. The connecting part 9 comprises a plurality of connecting segments which can be connected to one another in an articulated manner, or are held in their circular alignment with respect to one another by means of spring washers 24. As is illustrated in Figure 1, the arrangement of the segments of the connecting part 9 forms a conductive connection between the respective spherical end 8 or 8' of the respective contact elements 6 and 6' and the connecting part 9, such that, when the bus tie is completely installed, a conductive connection is formed between the contact parts 6 and 6' and, in consequence, a conductive connection is formed via the connecting holes 7 and 7' between busbars in the switch panels 2 and 3.

Description
Bus tie
The invention- relates to a bus tie for switchgear assemblies
for connection of two switch panels to an isolating arrangement
which in each case contains a contact arrangement and a field
control device which is connected to the contact arrangement.
A bus tie such as this is known from DE 101 19 183 Cl. The bus
tie disclosed there is intended for electrical connection of
two switch panels and has an isolating arrangement comprising
two bush elements and an isolating element between which a
field control apparatus is arranged; the isolating arrangement
contains a contact arrangement. In the case of this bus tie, a
field control apparatus is provided in the form of a field
control element which can be deformed elastically like rubber
and extends axially over the entire length of a connecting
element of the contact arrangement. This field control element
overcomes possible air enclosures in the interior of the bus
tie, in that the field control element is electrically
connected to the contact elements.
The object of the present invention is to specify a bus tie of
the type mentioned initially, which can be produced at low cost
and allows simple installation.
According to the invention, this object is achieved, in that the
isolating arrangement has a single separate isolating body with
an embedded field control apparatus for each switch panel, and,
in each separate

isolating body, the field control apparatus contains at least
one cylindrical control electrode which surrounds the contact
arrangement and is electrically connected to it.
An isolating arrangement such as this considerably simplifies
the installation of the bus tie according to the invention,
because the control electrodes of the field control apparatus
are embedded in the isolating bodies in such a way that there
is no need for complex and precise positioning of the field
control apparatus during installation of the bus tie, with the
control electrodes which are arranged in the isolating bodies
ensuring an adequate decrease in the field within the isolating
bodies, thus effectively preventing partial discharges in the
interior. In addition, the bus tie according to the invention
can be produced at comparatively low cost because it requires
only isolating bodies of the same design in order to produce
its isolating arrangement.
In a further refinement of the invention, the field control
apparatus has an opposing electrode, on the ground side, which
surrounds the cylindrical control electrode. An opposing
electrode such as this allows the field to be decreased in an
advantageous manner within the isolating body.
In one preferred embodiment, the opposing electrode is passed
out of the isolating body and ends in an attachment flange. The
attachment flanges allow the opposing electrodes to be grounded
in a simple manner by attachment to housing parts of the
switchgear assembly.
In one expedient development a contact element of the contact
arrangement is embedded in the respective separate isolating
bodies, to which contact element the respective control
electrode is electrically conductively connected. In an
arrangement such as this,

the potential- on the control electrodes is linked in a simple
manner to the high-voltage potential of the contact elements,
thus allowing the field in the isolating body to be decreased.
In a further refinement, the control electrodes are toroidal at
their ends facing the respective opposing electrode. A toroidal
configuration is particularly advantageous for decreasing the
field, because areas with corners or edges with a high field
strength are avoided.
In another preferred refinement, the control electrode projects
so far into a free space which is intended to hold a connecting
element of the contact arrangement, in the interior of the
isolating arrangement that contact is made with the connecting
element. This likewise forms a potential link, in a simple
manner, between the control electrodes and those parts of the
bus tie which carry potential, during installation of the bus
tie, with the annular control electrode having adequate field
control characteristics in order to decrease the field in the
interior of the isolating bodies.
In one expedient refinement, a seal is provided between the
isolating bodies. A seal such as this, for example in the form
of an earring or a sealing lip, provides protection in a simple
manner for the interior of the bus tie against environmental
influences.
The invention will be explained in more detail in the following
text using the drawing and one exemplary embodiment, and with
reference to the attached figures, in which:

Figure 1 shows one exemplary embodiment of a first embodiment
of the bus tie according to the invention;
Figure 2 shows a further exemplary embodiment of the bus tie
according to the invention; and
Figure 3 shows a perspective partial view of a bus tie
according to the invention.
Figure 1 shows a bus tie 1 for electrical connection of two
switch panels 2, 3 in a switchgear assembly, for example a
gas-insulated switchgear assembly. The bus tie 1 is in this
case symmetrical with respect to its center axis A, with that
part of the bus tie 1 which is associated with the switch
panel 3, corresponding to the parts associated with the switch
panel 2, being annotated with the same reference symbols but
with an apostrophe. The bus tie 1 comprises an isolating
arrangement 4, 4' with isolating bodies 4, 4', which are cast
from casting resin and have a respective free space 5 or 5' .
The respective free spaces 5 and 5' of the isolating bodies 4
and 4' in this case have a conical profile. Contact elements 6
and 6' , respectively, extend through the respective isolating
body 4 and 4' and, at one end, each have a connecting hole with
a respective internal thread 7 or 7' for connection to lines,
which are not illustrated in the figures, of the switch panels
2 and 3. The contact elements 6, 6' are spherical at the
respective end 8 or 8' opposite the connecting holes. A
connecting part 9 which is formed from an electrically
conductive material surrounds the spherical ends 8, 8' of the
contact elements 7, 1' and thus forms a conductive connection
between the contact elements 7 and 7'. The connecting part 9
will be explained in more detail with reference to

Figure 3. Control electrodes 10, 10' are embedded in the
respective isolating bodies 4 and 4', are conductively
connected at one end by means of respective connecting webs 11
and 11' to the respective contact element 6 or 6' , and are
toroidally curved in the direction of the free space 5 or 5' at
their respective other end 12 and 12' . Opposing
electrodes 13, 13' are encapsulated in the respective isolating
bodies 4 and 4' and are passed out of the isolating
bodies 4, 4' as flanges 14, 14'. The flanges 14, 14' are
attached to housing walls, which are not illustrated in the
figures, of the respective switch panels 2 and 3, for example
by means of a screw connection, which is not illustrated in the
figures, or by welding. The flanges 14, 14' are in this case at
ground potential. The respective control electrodes 12 and 12'
extend from the area of the respective connecting hole 7 or 7'
of the contact elements 6, 6' in the axial direction over the
connecting area between the connecting part 9 and the contact
elements 6, 6' into the area of the opposing electrodes 13,
13' . This arrangement of the respective control electrodes 12
and 12', which are at the same potential as the respective live
contact parts 6 and 6', via the connections 11 and 11',
respectively, leads to an adequate decrease in the field in the
interior of the isolating bodies 4, 4' and thus to avoidance of
partial-discharge processes in the free spaces 5 and 5' ,
respectively. A seal 15 in the form of an earring or a sealing
lip is provided in order to seal the bus tie against external
environmental influences, and is illustrated by dashed lines in
Figure 1.
Figure 2 shows a further exemplary embodiment of a bus tie 21
according to the invention, with only one isolating body 4 of
the bus tie 21 being illustrated in Figure 2. In contrast to
the bus tie 1 shown in Figure 1, an annular control
electrode 22 is provided in the bus tie 21, is encapsulated in
the isolating body 4, and has a connecting

area 23 which projects out of the isolating body 4 into the
free space 5 of the isolating body 4, to be precise in such a
way that, during installation of the bus tie 21, fitting of the
connecting part 9, which is not illustrated in the figure in
Figure 2, forms a conductive connection between the connecting
part 9 and the connecting area 23 such that, this conductive
connection keeps the control electrode 22 at the same potential
as the contact elements 6. A control electrode such as this
also ensures an adequate reduction in the field in the
isolating body.
Figure 3 shows a perspective illustration of an isolating
body 4 of the bus tie with the flange 14 and the free space 5,
with the connecting part 9 being mounted on the spherical end
8, which cannot be seen, of the contact element 6, which can
likewise not be seen. The connecting part 9 comprises a
plurality of connecting segments which can be connected to one
another in an articulated manner, or are held in their circular
alignment with respect to one another by means of spring
washers 24. As is illustrated in Figure 1, the arrangement of
the segments of the connecting part 9 forms a conductive
connection between the respective spherical end 8 or 8' of the
respective contact elements 6 and 6' and the connecting part 9,
such that, when the bus tie is completely installed, a
conductive connection is formed between the contact parts 6
and 6' and, in consequence, a conductive connection is formed
via the connecting holes 7 and 7' between busbars in the switch
panels 2 and 3.
