Description

The The invention relates to an arrangement system for a plurality of electrical / electronic components in particular a voltage converter device of a power supply system for use in oil / gas extraction with at least one support part, which at least one side a has bordered receiving recess, one in the receiving recess arranged, electrically connected to the components circuit carriers and one the circuit winner and / or the components in the receiving recess fixing holding part, being at least partially between circuit carriers and / or components and the support member insulating material is arranged.

A corresponding power supply system is in the WO 2003/026115 or the WO 2003/026111 described. A corresponding voltage converter device is connected on the input side to a DC voltage source and outputs on the output side to at least one electrical consumer via a cable connection a converted DC voltage. The corresponding converter device has a plurality of DC converter components, each of which is connected on the input side in series with the DC voltage source and on the output side in parallel with the cable connection for providing the converted DC voltage. By the converter device, for example, a DC voltage in the amount of a few kv in each case a few 1000 V is converted by each of the converter modules.

to Arrangement of corresponding electrical or electronic components such as diodes, IGBT, MOSFET or the like, for the realization such converter modules are required in connection with a circuit, a corresponding arrangement system is proposed. In a supporting part Such an arrangement system are the corresponding components and an associated one Circuit carrier arranged in a receiving recess. For fixing the components or the circuit-bearer a holding part is used, the components and / or circuit carriers in the Recording well fixed. To get an electrical breakdown between Circuit carrier and in particular to prevent the electrical / electronic components is an insulating material between circuit carriers and / or components and arranged the support part. At the same time this insulating material is used for heat transfer in particular the components to the support member, said support member then the heat outward can deliver.

To In the above-mentioned international applications, the voltage conversion device is below arranged at sea level. It is usually installed in a so-called subsea tree and serves to supply appropriate units of the tree such as Valve, throttle or the like. The corresponding arrangement system is also usually part of the subsea tree, being in this Case the heat emission from the supporting part takes place directly to the surrounding seawater.

There In this way, the support member is substantially grounded, is a sufficient electrical insulation of the corresponding components and optionally also the circuit carrier relative to the support member at the same time sufficiently good heat conduction Object of the present invention.

Around accommodate a sufficient number of components in the assembly system to be able to The support member can be arranged on both sides in top and bottom Have receiving wells. In each of these recording pits are then correspondingly a circuit carrier with associated components and a holding part arranged and also takes place an electrical Insulation of the components preferred by the insulating material over the Supporting part.

The Arrangement of the corresponding components, see the above international applications, may be similar in each of the receiving wells be to the corresponding serial arrangement of the individual converter modules the voltage transformers of the power supply system to enable.

Around in particular a good heat dissipation to allow a medium surrounding the array system this preferably has a substantially circular cross-section on. This is the surface relatively big and a good heat dissipation possible. This is especially true for a direct heat emission to the seawater, as stated above.

Corresponding to the circular Training of the arrangement system is in this context too the support member formed corresponding circular with a corresponding circular receiving recess, in the then circular or annular Circuit carrier and holding parts can be arranged.

Around the arrangement system, in particular in the field of components and the Circuit carrier from penetration of the external environment to protect, the receiving recess can be closed fluid-tight.

One simple embodiment for a circuit-bearer a board with printed circuit accordingly.

In such a board or ent speaking circuit breaker, the components are preferably arranged on this or this and / or at least electrically connected to this or this. The electrical connection is made via electrical lines that are soldered to connection points of a printed circuit.

A possibility for a Insulating material is an electrically insulating potting material. Such a potting material, for example, in the receiving recess poured in, then an arrangement of circuit carriers and / or components and then a fixation of these by the holding part. The potting material cures usually off and thus serves for electrical insulation and also for fixing the corresponding parts relative to the supporting part.

One Potting material is for example an epoxy resin, which depending on Thickness a corresponding dielectric strength in the range of several 100 V up to a few kV. At the same time has such Epoxy resin has a heat transfer coefficient on, which is usually greater than 0.1 W / m × K is.

at such a potting material is to be noted that this relative should be thick to achieve a high dielectric strength, and at the same time relatively thin should be to a high heat transfer to enable. To this contrary To meet demands must be a compromise on the thickness of the potting material being found. At the same time, the potting material usually needs are degassed, and also appropriate curing times are necessary to a sufficient mechanical strength before further assembly of the arrangement system.

at The potting material must also be noted that this in case of damage must be removed by appropriate mechanical methods, which then usually leads to destruction of the components and, where appropriate lead the circuit-holder. One such damage is, for example, an electrical breakdown or a crack in the cured Casting material.

Under Maintaining sufficient electrical insulation and simultaneous good heat transfer It is also conceivable, as an insulating material an electrically insulating To use foil. An example of such a film is a Ceramic film. This usually has a comparison with the potting material even higher Dielectric strength and also a higher heat transfer coefficient. For example, there are corresponding ceramic films that at a Thickness of about Withstand a mm of breakdown voltage of 10 and more kV and at the same time a heat transfer coefficient of more than 5 W / m · K. These are even compared to the above-mentioned potting compound more favorable values.

at Forming the arrangement system in circular form and corresponding circular or annular receiving recess of the support member, the film may be formed as a corresponding ring foil be inserted into the receiving cavity.

In As a rule, an arrangement of the film is at least partially between Bottom of the circuit carrier and / or bottom of each component and surface of the Recording well enough. In the field of components occur highest voltage values on, so that an arrangement of the foil only between underside of a every component and surface the recording deepening possible is.

in the Principle there is the possibility the film of different thickness corresponding to the occurring To create voltage values. For simplicity, however, points the film has a substantially constant film thickness. These is then chosen so big that Dielectric strength for the usually occurring voltage values for each component is given. To a corresponding heat transfer coefficient for the Foil to suffi cient removal of heat to the support member to allow the film is formed of a material having a high heat transfer coefficient be.

to simplified arrangement and removal of the film, this can be gluing-free be inserted in the receiving recess.

Around a sufficient dielectric strength especially in the area a corresponding depression edge of each receiving cavity guarantee, the film can in the receiving recess in particular to the recess edge be arranged. From this can be radially inward as a film ring extend, wherein the corresponding components preferably in the range of the film ring are arranged.

It has already been noted that the support member with appropriate Use of the arrangement system according to the invention with its outer surface directly in contact with seawater is. In order to allow little or no corrosion in this context, For example, the support part may be made of a material that is particularly resistant to seawater be formed like bronze or the like.

So that the holding part can fix components and possibly circuit carriers in a simple manner, the holding part can be a pressure part connected in particular to the carrier part by screwing be. Depending on the tightening of the screws, a more or less strong fixation of the corresponding parts by the holding part, whereby the holding part in particular can press the components to the insulating material and in particular to the surface of the corresponding film.

In The rule is a pressure exercise only required in the area of the film, so that an annular holding part usually enough. This extends, for example in the area in which also the film or ring foil is arranged is.

One Holding part, which also has a corresponding dielectric strength, can a holding part made of a fiber composite material, in particular be made of paper with phenolic plastic. Phenolplast is a phenol-formaldehyde resin and is called as fiber composite material with paper and hard paper.

Around Fix the holding part in a simple way sufficiently on the support part to be able to it is possible, that a plurality of screws for attachment from the holding part on Support member are arranged in particular along a circumference of the holding part.

It has already been noted that, where appropriate, an arrangement of the corresponding insulating material in the form of the film or the ring film in the area of the components considered sufficient can be. However, there is also the possibility that the insulating material or the film and between circuit board and corresponding surface extend the receiving cavity.

Around optionally by means of the holding or printing part directly on press on the corresponding component to be able to and at the same time sufficient space for the arrangement of connecting lines or wires can provide the holding part on its assigning the components Bottom of a plurality of pressure surfaces and / or receiving recesses exhibit. The printing surfaces can be provided according to the arrangement of the components and of on top of a top of the components when attaching the holding part Press down with the above screw. The printing surfaces are usually smaller than a corresponding surface of a Component. Furthermore, the receiving recesses are used for recording corresponding connecting lines between, for example, a Component and the circuit carrier.

Around In this regard, make sure that the holding part is right is assigned exactly to the components and the circuit carrier during assembly of the arrangement system, the holding part can have at least one insertion opening for an orientation means have for orientation of a component. By this means of orientation Before assembly of the arrangement system, the corresponding component fixed relative to the holding part, so that a corresponding assignment in particular of printing surface or receiving recess and component is ensured.

One simple orientation agent that simultaneously electrically insulating is, for example, an orientation pin made of a plastic material.

At the Screwing the holding part relative to the support member may continue be advantageous if between holding part and support member at least Compressible in the area of the fixing screw when screwed on Spacer rings are arranged. It consists, for example, the Possibility, that such intermediate ring of a compressible plastic material is formed. Such a plastic material is for example Polyurethane with a lower hardness.

Around the components relative to the circuit carrier at the appropriate place to arrange in a simple way, can the circuit winner component openings and / or to its outer edge have open component cutouts. The corresponding components such as diodes, MOSFETs or the like are then in these openings or cutouts can be arranged. It is done by this arrangement of Components an electrical connection to corresponding connection points of the circuit-bearer over wires and associated Soldered joints.

It may be sufficient if the holding part as the circuit carrier at least partially formed along a circumference fixing circumferential ring is. In this way, either the circuit-holder becomes direct or even a circuit breaker holding Fixed intermediate ring or the like. In this context are the components usually outside arranged the corresponding peripheral ring, so that this at least no component openings having.

Around the recording deepening opposite To seal the environment, a the receiving recess closing lid part above circuit-breaker and / or holding part may be arranged. This cover part is for example connectable by screwing with the support member fluid-tight. There are other types of attachment between the cover part and support member possible.

A corresponding closing of the receiving recess is not required for each support member when stacked one above the other. In this way, the stacked support members at least seal between them arranged receiving recesses from and only the top or bottom outwardly open receiving recess is closed fluid-tight by a corresponding cover part. In a suitably stacked arrangement of the support members, it may also prove advantageous if the corresponding parts are supported against breakdown in a receiving recess of a support member relative to the corresponding parts in the stacked support member. This can for example take place in that the holding part is formed as the receiving recess at least partially covering cover. Such a cover advantageously covers at least conductive parts within the associated receiving recess, so that there can be no breakdown of corresponding conductive parts in the receiving recess of the correspondingly stacked supporting part. In this context, it is possible to cover each of these receiving recesses by a corresponding cover.

In usually there is a stacking of supporting parts in such Number, which is a sufficient amount of converter components of the voltage converter device to convert a voltage of some 1000 V into some 100 V voltages are possible is. For example, if a total of the arrangement system is one Voltage of 3 kV and are for the appropriate facilities Tensions of the order of magnitude needed by 300V, so can For example, there are ten voltage conversion devices in the array system be. In this case, each support part has a converter module in each its recording pits, so that in the preceding numerical example a total of five such supporting parts arranged one above the other and are stacked.

A simple stackability of the corresponding components, for example be done by them by means of their receiving recesses bordering depression edges are stackable. In this way, only the corresponding depression edges of the one above the other arranged supporting parts stacked with up to the required number of supporting parts appropriate circuit-breakers, Receiving recesses, holding parts and components.

A simple shape of a recess edge, which allows a good stacking, can be seen in it, when the support member in the region of its recess edge has a cross-section in the form of a lying T substantially. The ends of the T-crossbar then serve as a stacking surface.

It there is also the possibility the components directly and without the above-mentioned orientation means to orient and fasten relative to the support member. Such possibility can be seen therein when the support member at least one electrically insulated screw-on opening for attachment to the support member by means of a particular screw having.

The electrical insulation of the Anschrauböffnung can, for example be carried out in that in this a sleeve of an electrically insulating material is used. In this way there is no contact between the screw and the component. The sleeve is sufficiently resistant to breakdown.

Farther can be beneficial in this context, when the sleeve itself at least into the insulating material or the corresponding film extends.

Around even with further tightening the screw a direct To avoid contact with the component, the sleeve may rest on the component sleeve edge exhibit. This then serves as an abutment for a screw head.

It there is also the possibility the components and optionally also the circuit carrier separately to attach, for which purpose, for example, the components and optionally the circuit carrier on a between holding part and insulating material or foil arranged intermediate plate in particular solvable are attached. The intermediate plate can by a correspondingly shaped holding part or printing part are then fixed relative to the support member. Also in This relationship is usually one along the circumference of the corresponding intermediate plate arranged annular retaining or pressure part sufficient.

Also for a Such holding or pressing part can be attached via a Variety of arranged along its circumference screws.

at Use of a corresponding holding part continues to exist Possibility, that an adhesive on a component-facing underside of the holding part is arranged. This adhesive can be used for fixation or orientation of the components serve, in this context the orientation means could be dispensed with.

When using a corresponding film as an insulating material usually shows a further advantage. The film can be formed, for example, from a material which can be at least partially deformed by pressure and / or heat. Such a material is in particular a corresponding composite ceramic. If appropriate pressure is then exerted by the holding part or, when the components are used, a corresponding temperature is generated, at least slight impressions of the result Components in the these components facing to the top of the film, which allows an improved dimensionally stable arrangement of the components. At the same time there is an improved surface contact between the component and the film for heat transfer.

A such foil can also Be flexible so they can easily fit into the appropriate receptacle before the arrangement of the other parts can be inserted. The foil can in their corresponding shape, for example by means of a jet of water get cut.

Around the interior of the layout system not only against intrusion from outside atmosphere or Protect the environment but at the same time also a corrosion largely inside To avoid this, the interior of the layout system can be essentially one inert atmosphere exhibit. This becomes, for example, in the interior of the arrangement system by rinsing with a corresponding inert gas and sealing the interior, for example through the one above the other stacked supporting parts and the corresponding lid parts included. An example for such an inert atmosphere is nitrogen of appropriate purity.

1 shows a plan view of an arrangement system 1 according to the invention with at least one support member 5 and one in a receiving cavity 6 of the supporting part 5 inserted foil 14 with usually constant film thickness 41 , please refer 6 , as insulating material 10 , The arrangement system 1 has a circular cross-section, wherein the film 14 as a ring foil in the corresponding circular receiving recess 6 of the supporting part 5 is arranged. Along one circumference 20 the ring foil 14 are a lot of holes 39 arranged, see also 3 and 4 , for fixing a holding part, not shown, on the support part 5 serve. As a rule, the ring film extends 14 up to an inside 40 of a recessed margin 17 , the recording well 6 surrounds.

Further parts of the arrangement system 1 are in 1 not yet arranged, see the following figures. The same parts are each provided with the same reference numerals, and they will be explained in part only in connection with a figure.

The arrangement system 1 consists of a plurality of corresponding support members with receiving recesses and further components arranged therein, see also 7 , stacked on top of each other. Each individual support part is assigned a converter module of a voltage converter device, of which several are connected in series with a line for supplying an input voltage. The input voltage is a few kV, with each of the converter modules converting part of this input voltage to a lower voltage output voltage. For example, with an input voltage of 3 kV, ten such converter blocks are arranged, each giving an output voltage of about 300V. A supporting part 5 is used according to an embodiment of the invention for the arrangement of two converter modules, see also 3 , wherein in each case a transducer module in a receiving recess 6 . 7 is arranged.

In 2 is a detail after 1 of the arrangement system 1 with additional components 2 . 3 and 4 as well as a circuit winner 8th shown. The corresponding foil ring 14 as insulating material 10 is also only partial compared to 1 shown. This foil ring 14 extends below the components 2 . 3 . 4 and between these and, see also 3 , a surface 16 the corresponding upper receiving recess 6 , The different components 2 . 3 . 4 are for example a diode, in particular Zener diode, a MOSFET or else an IGBT, where MOSFET stands for metal oxide semiconductor field effect transistor and IGBT for insulated gate bipolar transistor.

The corresponding components 2 . 3 . 4 are not directly on the circuit winners 8th in the form of, for example, a circuit board 13 arranged. Instead they are in corresponding component openings 28 or component cutouts 29 of the circuit-bearer 8th arranged. The corresponding component cutout 29 is in the direction of scope 31 of the circuit-bearer 8th open.

The other component 3 is between this scope 31 and the inside 40 of the supporting part 5 in the recording cavity 6 arranged. A set of connecting wires 43 each serve for electrical connection of the component 2 . 3 respectively. 4 with corresponding connection points on the board 13 or on the circuit-holder 8th ,

In 3 is a section taken along the line III-III 1 with additional holding part 9 in the recording cavity 6 shown. In 3 is particularly apparent that the support member 5 an upper and a lower receiving recess 6 . 7 has, so that a total of two of the above-mentioned converter blocks per support part 5 can be arranged.

Other arrangements for such converter modules are conceivable, such as only each arrangement of a converter module in a support member 5 with only one upper or lower receiving recess 6 . 7 ,

The supporting part 5 points in the area of the recess edge 17 a cross section of a lying T, wherein the ends of the T-bar a bottom 11 or top side 12 form that, see also 7 , for stacking other supporting parts 5 serve one above the other.

In the upper receiving recess 6 are the corresponding components 2 . 3 and 4 , see also 2 , arranged and with circuit board 13 or with circuit-breaker 8th over correspond de connection wires 43 connected. Below the components is the ring foil 14 as insulating material 10 between the component bases 15 and the surface 16 the appropriate recording cavity 6 arranged. The ring foil 14 is gluten-free in the receiving recess 6 and formed essentially of a composite elastic ceramic material with high dielectric strength and high heat transfer coefficient. In a corresponding composite ceramic material, for example, the dielectric strength at a film thickness of one mm may be several kV, whereby values up to 20 and more kV are possible. At the same time, such a ring foil has a relatively high heat transfer coefficient on the order of a few W / m · K, wherein a corresponding heat transfer coefficient can also be up to 20 W / m · K and more.

The ring foil 14 from this composite ceramic material is nachverformbar by applying pressure and / or heat. This means that the components resting on the surface of the film, upon application of a corresponding pressure or with sufficiently high heat, easily deform the upper side of the film, forming an intimate contact between the component and the film, which extends substantially uniformly over the film entire contact area of these two distributed.

The holding part 9 is formed as a pressure member by means of a plurality of along its circumference 20 arranged screws 19 , see also 7 , on the supporting part 5 in the field of recording 6 respectively. 7 is attached. The holding or pressure part 9 pushes the components and possibly also the circuit carrier 8th with its bottom 18 towards the surface 16 the recording well. To exercise a corresponding pressure, the holding or pressing part 9 in the field of components 2 . 3 . 4 Imprint areas 22 , see also 4 , on. These are located on top of the components 2 . 3 and 4 and press them when tightening the appropriate screws 19 firmly on the ring foil 14 ,

Furthermore, holding or printing part 9 in its bottom 21 a series of receiving recesses 23 pointing towards the surface 16 the recording well 6 are open. These receiving recesses 23 serve to accommodate in particular the connecting wires 43 extending between the respective component 2 . 3 respectively. 4 and a corresponding terminal on an upper surface of the circuit substrate 8th or the board 13 extend.

Furthermore, the holding or pressure part 9 in its bottom 21 insertion 24 for the inclusion of orientation agents 25 on. These orientation means 25 are for example orientation pins 26 , please refer 3 and 4 placed in corresponding openings of a component 2 . 3 and 4 are plugged in. They serve at least for temporary fixing of the corresponding components when assembling the arrangement system according to the invention on the holding or printing part 9 ,

The orientation pens 26 are made of an electrically insulating plastic, such as Polyethylelen or polyvinyl chloride and are relatively hard to be when plugged into one of the openings in the holding part 9 or component 2 . 3 and 4 not to deform.

In 3 and 4 is analogous to 2 respectively. 1 recognizable that the corresponding ring foil 14 mainly in the field of components 2 . 3 . 4 between these and surface 16 the associated receiving recess 6 respectively. 7 extends. This can be the ring film 14 to the inside 40 the corresponding depression edge 17 extend and fit tightly there.

To 3 can the holding or printing part 9 also as a cover 30 for at least partially covering the corresponding receiving recesses 6 serve to parts in this receiving recess with respect to parts in an overlying further receiving recess (or opposite the cover part) when stacking, see 7 to shield against breakdown.

For fastening the holding or pressing part 9 on the supporting part 5 inside the receiving cavity 6 respectively. 7 are 40 . 50 or more screws in corresponding holes along a circumference of the holding part inserted and with the support member 5 screwed, see also the further embodiment according to 7 , In 1 are in the area of the ring foil 14 analogue drilling 39 formed in this, through which the screws are passed for attachment of the holding part on the support member.

The structure in the area of the lower receiving recess 7 to 3 is analogous to, see also the above remarks, another transducer module in the lower receiving recess 7 to arrange.

In 4 is part of 3 shown enlarged, in particular the arrangement of the components between printing surface 22 on the bottom 21 the holding or printing part 9 and the ring foil 14 display. At one point after 4 is also a component by means of the orientation pin 26 on the holding part 9 held. Corresponding orientation pins are in principle also for holding the board 13 or the circuit-bearer 8th on the holding part 9 usable.

In 5 is a cut analogous to 3 illustrated for a further embodiment. It is in 5 a holding or pressure part 9 unnecessary.

In contrast to the embodiment according to 3 and 4 An attachment of the components 2 . 3 and 4 not at least provisionally on the holding part 9 but directly on the supporting part 5 , see the screws 35 , For this purpose, have the corresponding components 2 . 3 and 4 Bolt- 34 on, which are aligned with corresponding holes in the ring foil 14 or in the surface 16 the recording well 6 respectively. 7 are arranged. Incidentally, the arrangement of circuit carriers takes place 8th and components analogous to the preceding figures.

6 shows such attachment after 5 on an enlarged scale.

In the corresponding screw hole 34 of the component 2 is a sleeve for electrical insulation 36 arranged. This extends at least over the component 2 out into the ring foil 14 , The sleeve 36 has a sleeve edge resting on an upper side of the component 37 on, as a stop for a corresponding screw head of the screw 35 serves. Furthermore, between the screw head and the sleeve edge 37 corresponding washers 45 arranged. The sleeve is made of a relatively hard plastic material and provides a corresponding dielectric strength in the region of the Anschraubbohrung 34 for sure. At her the support part 5 assigning free end, the sleeve has a transition fit 44 in particular, the insertion of the sleeve in the Anschraubbohrung 34 facilitated.

One component per component is usually sufficient, with the bottom side 21 the corresponding holding or printing part 9 , see also 3 , Receiving recesses for receiving the screw heads after 5 can be provided.

In order to adapt the ring foil both the dimensions of the corresponding receiving recesses, as well as corresponding openings for screwing the screws 35 to 5 and 6 provided, this can be cut, for example, with a jet of water.

It is also conceivable that the corresponding components after their attachment to the circuit carrier 8th or on the board 13 through an adhesive material at the bottom 21 the holding or printing part 9 are attached prior to its insertion in the receiving recess.

It is also conceivable instead of using the corresponding film 14 a potting material as an insulating material 10 , This will be before inserting any further parts, such as circuit breakers 8th , Components 2 . 3 respectively. 4 and holding or pressing parts 9 poured into the receiving recess. Then takes place after insertion in particular of the components and the circuit substrate 8th and a corresponding fixing of these in the receiving recess by holding or pressing part 9 a curing of the potting material. An example of such a potting material is an epoxy resin. However, it usually turns out that such a potting material has a lower dielectric strength and a lower heat transfer compared to the corresponding ring of ceramic material. Furthermore, in a potting material is not easy disassembly of the arrangement system 1 possible because after curing of the potting material, the components and possibly also the circuit carriers are glued in the receiving recess. A repair of the corresponding supporting part 5 can only be done by mechanical release of this bond, which usually components and circuit breakers are damaged. In addition, is omitted in an annular film as Iso liermaterial a corresponding vacuum degassing of the potting material and also accounts for appropriate curing times for curing the potting material.

The corresponding potting material can also be used to attach the holding or pressure part 9 serve that when using a ring foil 14 by means of the above-mentioned screw releasably in the receiving recess 6 respectively. 7 is attached.

In 7 is a cut analogous to 3 represented by a further embodiment. In this case is in addition between components 2 . 3 respectively. 4 and circuit winners 8th or circuit board 13 an intermediate plate or an intermediate ring 38 arranged. This serves both for fastening the components and for fastening the circuit board carrier 8th , The attachment of these parts can be done by screwing, see also 6 , As a rule, the intermediate plate 38 is made of an electrically insulating material, if appropriate, on a corresponding sleeve 36 to 6 be waived.

For fixing the corresponding intermediate plate 38 relative to the ring foil 14 is the holding or pressure part 9 as a peripheral ring 32 educated. This extends substantially only along the circumference of the intermediate plate 38 between this and the inside 40 of the recessed margin 17 ,

For holding and pressing the intermediate plate 38 has the peripheral ring 32 a radially inwardly projecting retaining lug 46 on. This presses from above on the intermediate plate 38 and pushes it towards the ring foil 14 , Also in this embodiment, the ring foil 14 only in the area of the components 2 . 3 and 4 arranged within the receiving recess. In the area of the circuit-holder 8th or the board 13 As a rule, such an arrangement is not necessary since lower voltage values occur here.

For fixing the peripheral ring 32 Analogously to the preceding embodiments, a number of screws are used 19 , For this purpose, the peripheral ring 32 a series of holes along its circumference, wherein 30 . 40 . 50 or more holes can be provided. As a rule, these bores are arranged at equal intervals along the circumference.

Below the peripheral ring 32 are between this and the ring foil 40 in the area of the corresponding screws 19 intermediate rings 27 arranged. These are made of a relatively soft plastic material, such as polyurethane, so that the corresponding intermediate rings 17 when attaching the peripheral ring 32 are compressible.

In 7 is still recognizable that several of the supporting parts 5 one above the other by stacking corresponding upper and lower sides 11 . 12 in the area of the recess edge 17 can be arranged. The corresponding receiving cavities 6 . 7 are between the different carrying parts 5 sealed fluid-tight. Only at the top or bottom support part 5 are upper and corresponding lower receiving recesses 6 . 7 additionally by a cover part 33 closed fluid-tight.

According to the invention results in a simple, easy to repair and easy to assemble stacking of electrical / electronic components, such as those used for example for transducer components of voltage converter devices in the field of oil / gas extraction in so-called subsea trees in series. The electrical insulation of the corresponding components relative to the generally grounded support member by means of the corresponding ceramic film with high heat transfer through the film. This allows waste heat of the components in a simple manner via the support member on the outside thereof 42 be delivered directly to the environment such as seawater. The support member is in this context usually made of a seawater resistant material, such as bronze or the like. Additional cooling devices are not required on the one hand by the splitting into various devices per receiving recess and the good heat transfer via the support member to the environment. Furthermore, the interior is 47 of the array system filled with an inert atmosphere, such as relatively pure nitrogen.

By the appropriate arrangement and attachment of the various parts On the one hand, a simple assembly of the arrangement system is possible and On the other hand, a repair without damaging the corresponding components by replacing the damaged one Partly done.

There is also the possibility of the corresponding holding or printing part 9 See, for example, the figures, not only in the region of its circumference by screwing to attach to the support member. Instead, more screws can also be provided inside the holding or pressing part.
