Definitions
- the invention relates to the transmission of electrical power through a wall, and in particular the field of the devices for crossing the wall ("feedthrough" in English) and indenters.
- An indenter usually comprises two conductive elements in electrical contact with each other, and one or more insulative element (s) arranged around these conductive elements. This or these insulating elements are secured to the wall to be crossed, on either side of this wall.
- An indenter with conductive elements having a relatively large diameter section is known, thereby enabling relatively high current currents to be withstood.
- This indenter comprises insulating elements made of polymer.
- This indenter can withstand a pressure difference on either side of the wall of the order of 35 MPa (350 bar) for a temperature of 80 ° C. For higher temperatures, taking into account the degradation of the polymer, it is necessary to provide for smaller tolerable pressure differences, particularly if the indenter must be used for relatively long periods of time, of the order of twenty years per year. example.
- a system for transmitting electrical power through a wall comprising one (or more) housing intended to be mounted on either side of the wall to be crossed, and two subassemblies of indenter arranged on both sides. other of the housing, each indenter subassembly comprising a conductive element and an insulating element integral with each other.
- the system is arranged to maintain electrical contact between these conductive elements, while allowing relative axial movement of the conductive elements relative to each other.
- the insulating elements abut against the (or) housing so that the compressive forces experienced by each subset of indenter are at least partly transmitted to this housing.
- the system is arranged so that the compressive forces experienced by one indenter subset are transmitted to the housing rather than to the other indenter subset. This system thus makes it possible to decouple transmission of electrical power and transmission of forces.
- the insulating member or insulating member portion undergoing the compressive forces transmits these forces to the penetrator portion of the other side of the wall.
- the indenter works in both traction and compression.
- the proposed system is instead arranged so that each subset of indenter works in compression only.
- the insulating elements materials that relatively poorly support tensile forces, such as for example ceramic materials.
- These ceramic materials have the advantage of withstanding relatively high compression forces, for example of the order of 2000 bar (200 MPa).
- the invention is in no way limited to the use of ceramics.
- glass or else a polymer, for example a polymer Peek (trademark).
- a polymer for example a polymer Peek (trademark).
- the housing may be metal for example, or any other material capable of supporting the forces transmitted via the insulating elements.
- Each conductive element can be in one or more rooms.
- Each insulating element may be in one or more rooms.
- the invention can find an application in equipment intended to be placed at sea ("offshore” English), several thousand meters under water, for example pumps, compressors, or other.
- the pressure on one side of the wall of the pump housing may be the order of several hundred bars (several tens of MPa), while on the other side of the wall, the pressure of the pump can reach the thousand bars (several hundred MPa).
- the system is so arranged that the two indenter subsets operate in compression only, with the compressive forces experienced by each indenter subset being transmitted to the housing and not to the other indenter subset.
- the system may comprise a sleeve
- This sleeve may be made of elastomer or one (or more) other insulating material.
- the system may include during assembly a wind for balancing the interior of the system with the atmospheric pressure. The wind is then quenched, and the inside of the system is sealed.
- the system has no sleeve around the contact portion.
- the invention is not limited by the shape of the electrical contact part, as long as this part is arranged to allow relative movement of the conductive elements relative to each other.
- the insulating element of this subset may be arranged around the conductive element of this subset over at least a portion of the length of this conductive element.
- the system may comprise, for at least one indenter subset, a metal contact element disposed around and fixed to the conductive element of this indenter subassembly, and furthermore fixed to the element insulation of this indenter subset. Since the contact element is made of metal, the connection with the conductive element can withstand the shear caused by the compressive forces experienced by the indenter subassembly.
- the contact element and the insulating element may be designed to be fixed to each other by a seal substantially in a plane perpendicular to the plane of the axis of the system.
- this contact element makes it possible to secure the conductive element and the insulating element, even when the compression forces undergone are relatively high.
- the contact member may be attached to the insulating member by solder or other means, for example an O-ring and a screw system. Brazing is a sealing means resistant to relatively high pressures.
- the system advantageously comprises other sealing means for isolating the interior of the system from the outside, for example other solders or welds.
- the interior of the system can be filled with a fluid, for example air at atmospheric pressure, or even with oil.
- equipment for an underwater installation comprising one (or more) wall capable of withstanding a pressure greater than 20 MPa.
- the equipment further comprises a power transmission system as described above.
- the housing of this system is secured to the wall so as to allow the transmission of electrical power through this wall.
- the equipment may include a pump, a compressor, or the like.
- the wall, the indenter subassembly disposed outside the equipment and / or the indenter subassembly disposed inside the equipment, are advantageously capable of withstanding a pressure greater than 30 MPa, advantageously greater than 34.5 MPa, advantageously greater than 69 MPa, advantageously greater than 88.8 MPa, advantageously greater than 10OMPa, advantageously greater than 103.6 MPa, advantageously greater than 155.7 MPa, advantageously greater than 200 MPa.
- the wall, the indenter subassembly disposed outside the equipment and / or the indenter subassembly disposed inside the equipment are advantageously capable of withstanding a temperature or temperature difference between inside and outside the equipment greater than 50 ° C, preferably greater than 80 ° C, preferably greater than 120 ° C, and less than 1500 ° C.
- the wall, the indenter subassembly disposed outside the equipment and / or the indenter subassembly disposed inside the equipment are advantageously capable of withstanding a temperature below -20 ° C, advantageously less than -50 ° C, and greater than -200 ° C.
- insulating elements may be arranged directly against a third element itself arranged directly against the housing.
- the invention is therefore not limited by the manner in which an insulating element is disposed against the housing, insofar as the compressive forces experienced by the indenter subassembly are at least partially transmitted to the housing.
- FIG. 1 shows an example of an underwater drilling installation comprising equipment according to one embodiment of the invention.
- Figure 2 is a sectional view of an example of an electric power transmission system, according to one embodiment of the invention.
- FIG. 1 With reference to FIG. 1, there is shown an underwater installation 1 for the extraction of hydrocarbons from a well 2.
- pump 3 is supplied with electricity by a cable 4 from a boat 5, a platform or even a port.
- This pump 3 is placed in equipment, here a pump housing 6, having a wall 10 adapted to withstand an outside pressure PI of the order of 30 MPa and an internal pressure P2 of the order of 100
- the temperature T1 outside the pump housing 6 may be of the order of 1 ° C, while the temperature T2 inside the pump housing 6 may be about 120 ° C.
- a system 1 1 for transmitting electrical power through the wall 10 makes it possible to route the cable 4 to the pump 3.
- This system 1 1 makes it possible to transmit the electrical power necessary for the proper operation of the pump 3, and this under the pressure and temperature conditions described above.
- this system 1 1 provides for normal operation during a lifetime of about 25 years.
- FIG. 2 shows an example of an electric power transmission system 11 passing through a wall 10.
- the system 1 1 comprises a first subassembly of indenter 12 and a second subassembly of indenter 22 arranged on both sides of the wall 10.
- Each subassembly 12, 22 comprises a conductive element 14, 24, and an insulating element 13, 23, around the corresponding conductive element 14, 24.
- the conductive elements 14, 24 have a section dimensioned to withstand relatively high current currents, for example between 125 A and 2500 A, advantageously between 250 A and 1500 A, advantageously between 400 A and 1000 A, and also high voltages, for example between 3000 V and 200 kV, advantageously between
- 3600 V and 200 kV advantageously between 6000 V or 6600 V, and 200 kV.
- the conductive elements may for example have a section of about 50 to about 300 mm 2 .
- the two conductive elements 14, 24 are electrically connected to one another by a contact portion 36.
- this contact portion 36 has a portion 16 in one piece with the conductive element 14 and a female part 26 in one piece with the conductive element 24. This arrangement thus allows a relative axial movement of the conductive elements 14, 24 with respect to the other while ensuring electrical contact between the conductive elements 14, 24.
- the system 1 1 further comprises a first contact element 17 for securing the conductive element 14 to the insulating element 13.
- the conductive element 14 is made of metal, for example copper, while the insulating element 13 is made of an electrically insulating material, for example ceramic. It would be relatively difficult to find a means for directly joining these elements 13, 14 to one another and which is capable of withstanding relatively high shear forces.
- the contact element 17 being made of metal, it can be fixed, for example by soldering, on the conductive element 14.
- the solder 18 resulting from this brazing between two metal parts is able to withstand relatively high shear forces.
- the contact element 17 can also be fixed by soldering to the insulating element 13.
- the resulting solder 19 is intended to be mainly subjected to compressive forces, and should therefore be relatively little deteriorated by the pressure forces, even if this solder makes it possible to join two types of materials that are very different from one another.
- a second contact element 27 makes it possible to secure the conductive element 24 and the insulating element 23.
- the contact elements 17, 27 may be made of a relatively hard metal, for example steel.
- the braze fastening has the advantage of being relatively resistant to pressure, and may further enable two elements made of relatively different materials, for example a metal and a ceramic material, to be bonded to one another.
- the solder joint obtained has the advantage of being impervious to the surrounding fluid.
- the system 1 1 further comprises a housing 40 fixed to the wall 10 by screw type fixing means, and an elastomer sleeve 60 for sealing the contact portion 36.
- the housing 40 is arranged to let the sleeve 60 during assembly. Then a spacer 42 and flanges ("flange" in English) 41, 51 or discs ("pressure cap” in English) are attached to the housing 40 according to means well known to those skilled in the art.
- the insulating elements 13, 23 are soldered to the metal parts 41, 51.
- the insulating elements 13, 23 thus transmit to the housing 10 at least 80% of the compressive forces undergone by the pressure, which is advantageous at least once a year. At least 90% of these forces, advantageously at least 95% of these efforts, and advantageously all or almost all of these efforts.
- the insulating elements are arranged so that the solders 62, 61 fixing the insulating elements 13, 23 to the metal parts 41, 51 are likely to be subjected to compressive forces rather than to shear forces, when the system 11 is subjected to relatively high pressures.
- the system 1 1 further comprises a wind at the location 70, to balance the pressure inside the system, and in particular around the contact portion, with the external pressure.
- the wind is plugged, for example by welding.
- the interior of the system 1 1 is then isolated from the outside, thus preventing the entry of fluid.
- a slight radial clearance between the insulating elements 13, 23 and the respective conductive elements 14, 24 can be noted. This slight clearance can make it possible to make up for any defects in the positioning of these elements.
