Arrangement with a strain relief device The invention relates to an arrangement with a closure ^¬ means of a bushing device for at least one first conduit, wherein the closure means is supported on a wall and having a the wall crossing imple ^¬ approximately axis, and with a strain relief device which, at least the first line determines.

Such an arrangement is known, for example, from Offenle ^¬ tion DE 10 2011 003 253 AI. There is a An ^¬ order described with a closure device of a feedthrough device. The arrangement further comprises a strain relief device, on which several lines are fixed. The strain relief device is embedded in the closure device. This has the advantage that during a movement of the closure device the specified lines are also moved. The disadvantage, however, that holding forces are introduced from the strain relief device in the closure device. After a prolonged period of operation, fatigue cracks can occur due to the forces introduced at the closure device. To prevent this, the known locking devices must be checked regularly and replaced if necessary.

Thus, it is an object of the invention to provide an arrangement with a closure device, which is durable.

According to the invention the object is achieved in an arrangement mentioned above in that the strain relief device is supported on the wall.

A feedthrough device is used for a safe mechanical and optionally controlled / isolated electrical feedthrough of a line through a wall. loading Preferably, a fluid-tight passage of the line should take place via the closure device. In particular, the feedthrough device should be designed differential pressure resistant. Thus it is possible to use an arrangement according to the invention on a pressure vessel. It can be provided that the line passes directly through the closure device. For this purpose, the line can be embedded directly in the closure device. Optionally, the line may be discontinued, so that, for example, only one soul of the line passes through the closure device. However, it can also be provided that one or more connecting elements (in particular fluid-tight) are embedded in the closure device, which are connected to a respective section of the line on both sides of the wall to be crossed. Depending on the nature and structure of the lines to be led through a wall, connecting elements of various types may be used. For example, the line can have an electrical phase conductor (core), via which electrical impulses are transmitted. Furthermore, a line may have an optical conductor (core).

In addition, other versions of a line with other types of souls can be used. Regardless of the use of connecting elements or an immediate embedding of a line, only individual sub-elements (eg soul) of a line can be passed through the wall. For example, only an optical waveguide or an electrical phase conductor can enforce the wall, whereas cable sheaths, shielding, cushioning layers, etc. of the line are discontinued.

In the area of the feedthrough device, an exposed core optionally is present (z. B. manager), which comparatively ^¬ are unprotected passes through the wall. In order to prevent damage, the feed-through device should be assigned a pull-relief device. At the strain relief device, the lines routed through the feedthrough device are intercepted so that forces, in particular tensile forces, are removed from the feedthrough device. are held. The closure device of the feedthrough device is connected, for example, as an electrically insulating section with the wall through which the lines are to be performed. The wall and the closure device can be connected to one another in a fluid-tight manner. The

Closing ^device has a feedthrough axis, wel ^¬ che the wall traverses. The bushing axis defines the direction in which the pipes to be passed should pass the wall. The passage axis is, for example, a surface normal of the wall or the closure device. For example, the closure device of the feedthrough device can close an opening in the wall. The feedthrough axis may, for example, also be a surface normal of a passage area of the opening delimited by a body edge delimiting the opening.

The closure device and the carrying device should be connected to the wall independently of each other. Thus, it is possible to separate the two elements independently of each other from the wall. Accordingly, when one of the elements is removed, the other element can continue to fulfill its functions.

Furthermore, it can be advantageously provided that the at least one line is fixed essentially transversely to the passage axis running on the strain relief device.

As a rule, a line connects two points with one another, wherein the course of the line between the two points defines the longitudinal axis of the line. Depending on the laying path, the longitudinal axis of the line may deviate from a straight line. Thus, the directional statement refers transverse to the feedthrough axis on the region of the line which is in communication with the strain relief device. The line or the longitudinal axis of the line should be aligned transversely to the feedthrough axis aligned with the strain relief device. Thus, there is a rigid connection between the line and the strain relief / wall / closure device. Tensile forces are kept away from the feedthrough device. A transverse arrangement of the line also offers the possibility of allowing the at least one line to run toward the feedthrough device substantially parallel to a surface of the wall. Accordingly, there is a flat-building feedthrough device together with strain relief device. A recess (eg, penetrated by the longitudinal axis of the line) for fixing a line to the strain relief device may, for example, have a substantially radial orientation with respect to the feedthrough axis.

Advantageously, it can further be provided that a plurality of lines with respect to the lead-through axis are fixed substantially in a plurality of radial directions running on the strain relief device.

A use of a plurality of radial directions allows a beam-shaped tapering of the lines to the feedthrough ^¬ device. So it is for example possible to run several dung Lei ^¬ obligations substantially parallel to a surface of the convertible. This has the advantage that several lines can be fanned out directly accessible. By avoiding bundles of lines, a mutual influencing of the lines is counteracted. For example, overheating of the lines is counteracted, since a simplified heat release is made possible due to the planar arrangement of the lines. Next is a radial Reg ^¬ th of pipes advantageous to use short cables. The conduits can go to the bushing device from different directions. Line-extending detours can thus be avoided.

Advantageously, it can further be provided that, with respect to the leadthrough axis, a plurality of lines staggered in different planes are fixed to the strain relief device.

A feedthrough device can be configured to also lead a larger number of lines through a wall. For example, it can be provided that several Lines in the direction of the feedthrough axis staggered ange ^¬ arranged are. In this case, only one of the lines can be defined in each level. However, several lines can also be arranged in one level. A distribution of the line on several levels allows an increased number of lines from radial directions to run to the feedthrough device. In this case, in the same radial direction or in different radial directions extending lines can be determined based on the course of the feedthrough axis in different levels on the strain relief device. Furthermore, the possibility ge ^¬ create lines in different levels set to intersect these against each other. Thus, the shortest possible laying of lines is achieved. Kön- according to need NEN several be similar seen on the feedthrough device to lines ^¬ running in the direction of the guide shaft almost identical fixed to the strain relief device (in particular in different planes). Furthermore, a staggering in different levels also allows a separation of the lines from each other. For example, lines with similar diameters or the same structural design etc. may be arranged in common in one plane. However, it may also be provided logical assignments of the lines of a level. For example, in a first level, lines of a first device and in a second level lines of a second device may be arranged on the strain relief device.

Advantageously, it may further be provided that the tension relief device has a carrying device, in particular in the form of a frame.

A carrying device can form a chassis of the strain relief device, in which the forces emanating from fixed lines are introduced. The carrying device can be connected to the wall. Thus, it is possible to first define lines to the strain relief device and in the following, the support means with the wall connect. In particular, in repair work as a removal of the cables is made possible together with the support means of the wall. A frame can embrace a recess in itself closed. If necessary, the frame is interrupted, so that a completely closed circulation is interrupted. The frame may be polygonal, in particular polygonal shaped. On the support means lines can be set in different positions. For example, clamping blocks can be screwed to the carrying device so that interposed lines are fixed in place. The support device may be constructed, for example, one or more parts. Preferably, the Tragein ^¬ direction should be formed annularly and preferably the front side facing the wall / on the wall abut gene.

Furthermore, it can be advantageously provided that the closure device and the carrying device have different materials.

The carrying device and the closure device may have mutually differing materials / material connections. For example, the closure device can act as an electrical insulator, while the support device is designed to be electrically conductive. Thus, it is for example possible to embed the line / a connection element electrically isolated in the closure device. For example, an electrical insulation of a phase conductor (a soul) of the line can be realized by the closure device. Accordingly, the area necessary for carrying out a line is reduced at the feedthrough device, so that the number of lines led through the closing device can be increased. The closure device of the feedthrough device may, for example, an electrically insulating portion of an electrical insulating material such. B. insulating resin, ceramic. The support stabilizes the strain relief device. The support means may be performed, for example, electrically conductive. Accordingly, in addition to a mechanical stabilization, the carrying device can also bring about a dielectric influencing of electric fields. The

Carrying device may be, for example, a metallic Tragein ^¬ direction, which leads earth potential. Irrespective of the choice of material, the closure device and the carrying device should be arranged so as to be angularly fixed relative to one another. Thus, before a passage of the lines through the

Wall on the lines acting external forces intercepted via the strain relief device. At the feedthrough device, the lines may be at rest. Furthermore, it may be advantageous for the carrying device to have at least one section of a path circulating through the feedthrough axis.

The carrying device should preferably be closed around the feedthrough device in a closed manner. At a minimum, the carrying device should follow a part, in particular the largest part, of such a circulation. Thus, it is possible that the support means passing through from ^¬ turn recess penetrated by the lines be carried out, wherein a support on the support means of the

Lines done. By the support means all fixed to the support means lines are fixed relative to each other, so that even with a release of the support means of the wall to be passed the lines remain held on the strain relief device.

Advantageously, can further be provided that the at least one line between ^¬ particular substantially stacked in the direction of the guide axis-sequential clamping is set buck.

A clamping block has a clamping region, on which a positive and / or positive a line is held. The clamping The area should be shaped in such a way that the lines are approximately complementary in shape, with the longitudinal axis of the held line being aligned transversely to the feedthrough axis, in particular substantially radially with respect to the feedthrough axis. By an approximately formkomple ^¬ mentary design of the clamping area jamming of the line is possible. For this purpose, the expansion of the line in the clamping direction should preferably have a larger dimension than the approximately complementary shape encompassing. A tension of the clamping area against an abutment leads to a determination of the clamped line. As an abutment, for example, the support device or another, especially identical clamping block is suitable. For example, a stack of clamping blocks makes it possible to define multiple levels (eg between the clamping blocks) in which different lines are defined. The clamping blocks located in a stack can be pressed against one another, for example, by at least one common Ver ^¬ clamping element. This bracing element can, for example, press the stack against the support device.

It can be further advantageous that the

Clamping blocks without twisting complementary form in each other grei ^¬ fen.

The individual clamping blocks should form complementary Oberflä ^¬ chenabschnitte have, so that the clamping blocks engage with each other and fixed in the clamping region inserted line. In particular, insertion of lines into the clamping regions of the clamping blocks is facilitated. By a Ver ^¬ rotation lock the terminal blocks remain aligned relative to each other in alignment, so that the individual clamping areas also find an abutment and the lines can be held. As a rotation, for example, a guide pin of a first clamping block engage in a formkomple ^¬ mentary recess of a second clamping block. First and second clamps can be similarly shaped. Furthermore, it can be advantageously provided that clamping blocks are arranged staggered relative to each other in a radial direction. The terminal blocks (the through axis with respect to z. B.) one behind the other can be arranged at staggered ^¬ in a radial direction. In this case, the clamping blocks can overlap each other over ^¬ , which are kept free by a transverse offset whose clamping areas. This allows a close juxtaposition of fixed lines. For example, the support means may be annular, wherein at least a first and a second diameter-different circular path are arranged concentrically with each other. Corresponding clamping blocks are arranged distributed on the two circular paths. The circular paths surround the passage axis.

It can further be advantageously provided that the radially ge ^¬ staffelten clamping blocks overlap each other. In a radial direction, a portion of a clamping block of a circular path may be overlapped by a clamping block of the other circular path. Depending on requirements, different positions on the support means may be occupied by clamping blocks. Depending on requirements, more lines can be intercepted in one sector of the carrying device than in another sector. Accordingly, staggered arranged clamping blocks can be pivoted in azimuthal direction to each other, wherein they overlap each other. At least the clamping areas of all occupied clamping blocks should remain free of overlaps, so that a direct access of fixed lines to the feed-through device is possible. Unused clamping areas can also be retrofitted with cables.

Advantageously, it can further be provided that the tension relief device has a grounding fixed point for the at least one line. To protect against interference fields, a line may have an electrical shielding. Depending on the type of cable, it may be necessary to cover the shielding with a defined electrical potential. The earthing of such shieldings is advantageous. A grounding to be grounded is electrically contacted with a grounding fixed point. The strain relief device may be equipped with a grounding point. For example, the support device may have this grounding point. For this purpose the Trageinrich- tung can at least partially electrically conductive leads out ^¬ be where they lead ground potential. The support means may for example be connected to an electrically conductive wall, wherein the wall earth potential leads. Furthermore, it can be provided that the clamping blocks are designed to be electrically conductive and lead to earth potential. In this case, the shielding is exposed, for example, in the clamping region of the Klemmbö ^¬ bridge and is electrically contacted in a clamping the clamping block. The clamps can do this example ^¬, be electrically conductive contact with a ground potential leading support device. It can be provided that a common Verspannelement is used, which causes a securing of the line to a terminal block and the clamping block relative to the support means and on the other hand applies the necessary contact force for electrical contacting of the shield.

It can further be advantageously provided that the shutter ^¬ means forming a portion of a fluid-tight barrier of a capsule housing.

The closure device is a region of the feedthrough device in which the lines / connecting elements to be passed through a wall have an axial alignment in the direction of the passage axis. The feedthrough device may for example be encompassed by the carrying device (when projecting in the direction of the feedthrough axis). The closure device can at least partially ^¬ accessible through a recess of the support device be. It is advantageous to use the closure device as a fluid-tight section of an encapsulating housing. The closure device can, for example, embed the lines or sections of the lines or connection elements in a fluid-tight manner, the closure device itself being connected in a fluid-tight manner to a wall of the encapsulation housing. The carrying device can encompass and stabilize the feedthrough device. The support device can also be constructed in several parts. The encapsulating housing may, for example, be an electrically conductive housing on which the lead-through device forms an electrically insulating section (eg via the closure device). The encapsulating housing may for example be a metallic housing. The closure device forms part of a fluid-tight barrier of the encapsulating housing. This barrier also has, for example, the wall. The Verschlussein ^¬ direction can provide an electrically insulating area available within the (particularly electroconducting ^¬ ELIGIBLE) wall.

Advantageous may be further provided that the encapsulation ^¬ housing encloses a hollow volume, said strain relief ^¬ device is disposed within the hollow volume. An encapsulating housing can enclose a hollow volume which is hermetically sealed. Within the encapsulation ^¬ housing, an electrically insulating fluid can be arranged. Electrically insulating fluids can be present, for example, as sulfur hexafluoride gas, carbon dioxide gas, nitrogen gas, insulating oil, etc. The electrically insulating fluid circulates around ^¬ within the encapsulating housing arranged Phasenlei ^¬ ter, which serve to guide an electric current. In order to increase the insulation strength, the fluid can be enclosed in the hollow volume under overpressure.

The encapsulating housing may, for example, be part of a pressure-fluid-insulated electric power transmission device, within which a fluid is trapped under overpressure is. The encapsulating housing may have an opening, wherein the opening is equipped with an arrangement according to one of the claims 1 to 14. Next, can advantageously be provided that a transducer is arranged in the encapsulating housing ^¬.

Electric power transmission devices have phase conductors for conducting an electric current. The phase conductors are electrically insulated from deviating potentials leading components. Especially at high voltages / high currents direct measurement of current and / or voltage is not readily possible. Instrument transformers are used to convert a current to be measured / a voltage to be measured and to transmit it in a standardized format. For example, using the transformer principle, transducers can decouple measured quantities by means of transducers.

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

It shows the

4 shows a stack of clamping blocks. FIG. 1 shows a section of a fluid-tight encapsulating housing 1 of an electric power transmission device. The encapsulating housing 1 is presently a metallic Gussge ^¬ housing, which leads earth potential. The encapsulating housing 1 is equipped with a first flange 2 and a second flange 3. The two flanges 2, 3 are formed as annular flanges and being ^¬ each directed coaxially to a longitudinal axis. 4 The two flanges 2, 3 are arranged spaced apart from each other with opposite sense of direction and mitein ^¬ connected via egg ^¬ nen lateral surface portion 5 of the encapsulating 1 mitein ^¬ . The flanges 2, 3 are adapted to close the encapsulating housing 1 in a fluid-tight manner. This can be done, for example, by bulkhead insulators, sealing caps, by other encapsulating housings, etc. The encapsulating ^¬ housing 1 limited (together with other elements) thus a hollow volume. The interior of the encapsulating housing 1 is filled with an electrically insulating fluid, in particular sulfur hexafluoride gas. The electrically insulating fluid circumscribes a plurality of phase conductors 6a, 6b, which pass through the two flanges 2, 3. The phase conductors 6a, 6b can continue into other, adjacent to the capsule housing 1 Kapselungsge ^¬ housings. The phase conductors 6a, 6b are electrically insulated by the electrically insulating fluid and held by support insulators, not shown in FIG. The phase conductors 6a, 6b serve to guide an electric current for the transmission of electrical energy. The phase conductors 6a, 6b are surrounded by transducers 7a, 7b. The transducers 7a, 7b each have a plurality of measuring windings, which are penetrated by the respective phase conductors 6a, 6b. In the present case, these are measuring windings which operate according to the transformer principle and map a current flowing through the respective phase conductor 6a, 6b. The information supplied by the measuring windings are fed via lines 8 through a wall (here lateral surface section 5) of the encapsulating housing 1 to the outside. Outside the Kapse ^¬ development housing 1, the measured values of the measuring coils can be processed and evaluated. The encapsulating housing 1 is provided on the shell side with an opening 15. The opening 15 has a substantially circular cross-section. The opening 15 is bounded by a body edge of the wall. Inner sheath side is the Opening 15 associated with a support means 9. The carrying device 9 is part of a strain relief device and rigidly connected to the wall. The carrying device 9 has a recess through which a closure device 10a of an feedthrough device 10 is accessible. The support device 9 is designed as a frame, in particular as a circular ring. The present circular ring has a highly cylindrical basic shape. The support means 9, the opening 15 is encompassingly supported on a limiting the opening 15 body edge of the wall. The opening 15 is fluid-tightly closed by means of the feedthrough device ^¬ 10th The feedthrough device 10 has an electrically insulating closure device 10a with a substantially circular-cylindrical contour. The closure device 10a is part of a fluid-tight barrier that is also formed by the wall. The feedthrough device 10 has a

Flange ring on. The flange presses the closure device 10a against the opening 15 limiting body edges of the wall. The opening 15 is closed in a fluid-tight manner. In the feedthrough device 10, a plurality of electrical connection elements are embedded in a fluid-tight manner, which pass through the wall of the encapsulation housing 1. The electrical connecting elements are electrically iso ^¬ lines spaced from each other. The electrical connection elements run essentially in the direction of a

Bushing axis. With the connecting elements in each case the lines 8 are connected. Instead of using the connecting elements, alternatively or additionally, the lines 8 themselves can be embedded in the closure device in a fluid-tight manner.

The lines 8 run from a transducer 7a, 7b as directly as possible in the direction of the feedthrough device 10 with the strain relief device. The Leitun- gene 8 of the inner surface of the encapsulating housing 1 are fol ^¬ quietly, the through axis with respect to the strain relief ^¬ processing device from radial directions zustrebend, excluded directed. The individual lines 8 radiate toward the strain relief device.

At the support means 9, the lines 8 are fixed. The strain relief device has to several stacks 11 of

Clamping blocks 12 which are fixed to the support means 9 (construction and winding manner of stacks 11 and Klemmbö ^¬ blocks 12, see description of Figures 3 and 4). The lines 8 are fixed radially to the strain relief device, wherein the direction refers to the feedthrough axis of the feedthrough device. The lines 8 essentially follow the course of the inner circumferential surface of the wall, in order to be fixed to the strain relief device from radial directions in the direction of the

Implementation axis to be redirected. The cores (cores) of the lines 8 are exposed by settling the lines 8 and connected to the electrical connection elements of the feedthrough device 10. For reasons of clarity, it has been dispensed with in the figures to illustrate a course of the lines from their radial course to the axial course and the contacting of the electrical connection elements of the feedthrough device 10.

In FIG. 2, the encapsulating housing 1 is shown in section, wherein a representation of the phase conductors 6a, 6b and the measuring transducers 7a, 7b has been dispensed with. In the figure 2, the feedthrough device 10 and a further feedthrough device are shown. In the present case the feed-through device 10 is used for the lines 8 of a transducer 7a and the further implementing device for Lei ^¬ obligations 8 of the other transducer 7b. In the figures, the lines 8 are each shown as truncated sections from ^¬ sections. FIG. 3 shows, by way of example, the arrangement of a plurality of stacks 11, each of which comprises a plurality of clamping blocks 12. The Tragein ^¬ direction 9 is designed as a metallic frame, which leads earth potential. The support device 9 is connected to the Encapsulated housing 1 and electrically connected to the Kapse ^¬ ment housing 1. For screwing to the wall, three through holes are introduced into the carrying device 9 on the front side, in which heads of fastening screws are arranged sunk. At the front two concentric circular paths are still set. On each of the circular paths a plurality of stacks 11 are distributed by clamping blocks 12 is arranged ^¬ . The stacks 11 are in the respective circulation on the

Circular paths arranged such that in a projection in a radial direction, the stack 11 overlap each other partially over ^¬ , each stack 11 has a direct radial access to a clamping region of the lines 8. Each stack 11 has two clamping blocks 12, wherein at least one line 8 between a lower clamping block 12 and the support device 8 and a further line 8 between the lower clamping block 12 and an upper clamping block 12 is pressed. Depending on requirements, the number of clamping blocks 12 of a stack 11 can vary. In the present case, each of the fixed lines 8 has a first and a second wire, wherein the wires are exposed by staggering the lines 8 (see Fig. 4). In the region of the clamping seat of the lines in the respective stack 11 a shielding of the lines is exposed. The shielding stands in electrically conductive contact with a clamping block 12. The clamping blocks 12 have electrically conductive surfaces and are preferably metallic clamps 12, which have on the one hand good mechanical as well as electrical egg ^¬ properties. Thus, the clamping blocks 12 are in electrical contact with the grounded support means 9. So it is easily possible to hold the lines and ground a shield of the lines.

Wedged between the clamping blocks 12 of the individual stacks 11 in clamping areas, the individual lines are distributed in different planes. Depending on the height of the stack 11 / number of clamping blocks 12, the number of vary. The terminal areas each defined by an off ^¬ groove to the terminal blocks.

Figure 4 shows an example of a structure of a stack 11 of clamping blocks 12. The clamping blocks 12 are each carried out similar. The clamping blocks 12 are constructed as traverse, which at their ends using a respective clamping means

13 are braced against each other. Herein refer to the clamping ^¬ buck 12 recesses, is guided through each of which a screw as tensioning means. 13 The clamping means 13 durchset ^¬ zen each clamping blocks 12 of a stack 11. The Klemmbö ^¬ bridge 12 are each provided substantially with a U-profiling. Each of the clamping blocks 12 has in each case at the end ei ^¬ NEN guide pin 14 which engages in a recess (here U-profiling) of an adjacent clamping block. The guide pins 14 of a stack 11 final terminal block 12 do not engage in another terminal block 12 a. These guide pins 14 are used as a stop for Gewindemut ^¬ tern 16 of the clamping means 13. By the guide pin 14 a rotation is given, which allows easy installation.

The clamping portions of the clamps 12 each include an off ^¬ groove in order to pinch inserted lines there. The groove defines the course of the specified line 8 to the support device 9. In an abutment region for a clamping region of a clamping block 12, a profiling of the surface may be provided in order to produce a stable clamping seat. In the present case, an additional plate 15 is inserted in the respective abutment area. The plate 15 is part of the stack 11 and penetrated by the clamping means 13.

In the figure 4 is shown with a broken solid line, the support means 9, which forms an abutment for the clamping region of the support means 9 nearest clamping block 12 of the stack 11. The clamping blocks 12 are each ^¬ Weil equipped with guide pins 14. The guide pins

14 are on each side of the clamping area / the counter bearing on each terminal clamp arranged. The guide pins 14 engage in a shape-complementary formed surface area of an adjacent clamping block 12. The guide pins 14 serve to guide the clamping blocks 12 with each other and prevent a relative transverse movement of the clamping blocks 12 with each other. Thus, in particular in the unstressed state of the stack 11, a simplified insertion of the lines 8 is possible. In addition to a guide of the clamping blocks 12 in the stack 11, the guide pins 14 also serve as a stop for threaded nuts 16, against which the clamping means 13 are clamped. The Füh ^¬ approximately pins 14 act as a stop, so that the threaded humility ^¬ tern are secured against rotation. Thus, it is possible to screw the screws (clamping means 13), wherein no tool for holding the threaded nuts 16 is necessary. In the figures 1 to 3 respectively the equipment of the stack 11 is shown in each case with two clamping blocks 12. FIG. 4 shows the possibility of providing further levels by increasing the number of clamping blocks 12 within a stack 11. In FIG. 4 it becomes clear that the present lines 8 each have two cores (souls) within a common jacket. The jacket still surrounds a screen. The lines are stripped in the area of the clamping blocks 12 to the screen, so that the screen enters into electrically conductive contact with the clamping blocks 12 and thus can be acted upon Erdpoten- tial.
