Definitions

  • the invention relates to an induction cable with a plurality of cable cores, each of which has a conductor strand surrounded by insulation, the conductor strand comprising a plurality of conductor sections which are spaced apart in a longitudinal direction of the cable at resonance separation points by insulating intermediate regions with at least one intermediate piece.
  • the invention further relates to a coupling device for such an induction cable and a method for producing such an induction cable.
  • Such an induction cable also known as an inductor, is used to form one or more so-called induction fields.
  • the induction cable is intended in particular for inductive heating of oil sand and/or heavy oil deposits.
  • Such an application of such an induction cable is, for example, from EP 2 250 858 B1 refer to. The technical constraints resulting from this application are met by the induction cable.
  • the individual cable cores of the cable are separated at defined separation points in a grid dimension with a defined length of, for example, several 10 m.
  • Each of the cable cores is divided into a number of core sections by the separation points.
  • several cable cores are preferably combined into core groups, with the separation points or interruptions of the cores of a respective core group being essentially at the same length position.
  • the separation points of a first group of wires are halfway between in the longitudinal direction two separation points of a second group of wires are arranged. This results in an overlap of the wire sections of different groups, which is used in particular to form an induction cable.
  • Such a cable is, for example, in the WO 2013 079 201 A1 described.
  • the respective cable core i.e. a conductor surrounded by an insulating jacket
  • the wire ends are attached to the connector on both sides of the intermediate piece.
  • the connector is designed like a sleeve on its opposite end faces, so that a respective wire end, that is, in particular also a part of the insulation jacket, is encompassed.
  • Such induction cables are usually pulled into prepared tubes in the induction field.
  • the length of each induction cable ranges from several hundred meters to kilometers.
  • Such an induction cable is typically composed of a plurality of wire bundles, which are in particular stranded together.
  • the entire stranded composite typically has a diameter in the range of several centimeters, for example in the range of 5 to 20 cm.
  • the invention is based on the object of specifying an improved induction cable which is easier to provide and lay.
  • the object is achieved according to the invention by an induction cable with the features of claim 1.
  • the induction cable then comprises a plurality of cable cores, each of which has a conductor strand surrounded by insulation, which comprises a plurality of conductor sections which are spaced apart in the longitudinal direction of the cable at resonance separation points by insulating intermediate areas.
  • the intermediate region is formed by at least one insulating intermediate piece; at least one such intermediate piece is arranged in the intermediate region.
  • a coupling device is integrated into the induction cable and at least several of the conductor strands are interrupted at a coupling position and each have a pair of coupling ends, which are connected to one another at the coupling position using the coupling device.
  • the coupling device has a coupling module as an additional component, which is provided with receptacles for the coupling ends. Several of the conductor strands are held together on the coupling module with their coupling ends.
  • the cable is therefore divided at the coupling point to form two cable ends connected to one another via the coupling device.
  • the coupling device therefore provides a unit for connecting several of the conductor strands, for example half of the conductor strands or all conductor strands, so that these several conductor strands are connected to one another in a simple manner via the coupling device.
  • the coupling device generally simplifies the production, provision or laying of the induction cable.
  • the induction cable does not need to be manufactured in one piece over its entire length. Rather, it can be divided into individual sections.
  • individual cable sections are provided, which are provided as such at the installation location near the induction field and only need to be connected together immediately when laying. This enables simplified transport and overall easier handling. Furthermore, this also makes repairs easier, since in the event of a defect only the defective cable section needs to be replaced.
  • the first-mentioned variant of the coupling device in which only some of the conductor strands are connected via the coupling device, advantageously uses the fact that the individual conductor strands comprise individual conductor sections with a predetermined length that are separated from one another by the intermediate regions. With the help of the coupling device, the individual conductor sections can therefore be provided during production as individual lengths with a defined grid length and can be connected to one another via the coupling device.
  • the coupling device has two coupling parts for bringing the two cable ends together.
  • the two cable ends are received and held in these two coupling parts and the coupling device is designed overall in the manner of a plug connection, screw connection or even snap connection.
  • the two coupling parts are brought together in the longitudinal direction of the cable. When this is brought together, the individual separate conductor strands of the induction cable are then automatically connected.
  • the coupling device is designed as a reversibly detachable device, so that the individual coupling ends, in particular the two cable ends, can be reversibly connected to one another by means of the coupling device are connectable. This allows easy separation even after assembly, for example to replace a defective section.
  • the individual coupling ends of the individual conductor strands are preferably brought together via plug connections.
  • plug connection elements are attached to the coupling ends, for example welded, soldered, crimped or even molded on.
  • the coupling ends are inserted into the receptacles of the coupling module or into suitable connecting pieces inserted in the receptacles. In both cases, the coupling ends are preferably prepared appropriately.
  • the coupling device is arranged at the resonance separation point, i.e. at a length position of the induction cable at which some of the conductor strands have intermediate pieces.
  • several groups of conductor strands are formed in the induction cable, in particular two groups, with each group having the intermediate regions at identical length positions.
  • the opposite conductor ends of the conductor strands form the coupling ends.
  • the intermediate areas are therefore integrated into the coupling module.
  • the coupling module therefore has a plurality of first receptacles of a first type of connection, with at least one intermediate piece being arranged in each of the first receptacles.
  • the individual groups of conductor strands are usually spaced apart from one another by a defined distance, which remains constant over the longitudinal direction of the cable. For two groups, this distance is half the grid dimension, i.e. half the distance between two resonance separation points,
  • the coupling module comprises several second receptacles of a second type of connection, the two coupling ends being electrically conductively connected to one another in the second receptacles.
  • the conductor strand is in the area of a respective conductor section via the coupling device interrupted and electrically connected via the coupling device.
  • the coupling module has both first receptacles with the integrated intermediate pieces and second receptacles for the electrically conductive connection.

  • the sleeves are made either of an insulating material or of a conductive material. In the former case, they preferably form an intermediate piece for the formation of a resonance separation point.
  • the sleeves are designed, for example, as a double sleeve with an intermediate piece arranged between opposite sleeve sections. Ceramic is used in particular as the material for the insulating sleeve in order to achieve high partial discharge resistance.
  • the coupling connection between the coupling ends or a fastening of the coupling ends in the sleeves is expediently formed using a profiling.
  • a profiling This can be done either optionally or in combination
  • the profiling is designed as a pull-out protection, so that a high pull-out strength is formed in the axial direction.
  • the profiles are designed, for example, in the manner of, in particular, circular ribs or also in the form of barbs.
  • a thread is formed by the profiling, so that the two parts can be screwed into one another.
  • the sleeve has threaded elements on its inner wall and, correspondingly, the coupling end to be inserted into it also has a threaded element, so that the two partners are connected to one another by screwing them in.

  • a receptacle is provided at the positions occupied by the individual conductor strands in the cable assembly.
  • the same conductor strand pattern is reproduced via the carrier as is also present in the induction cable. The retention of the conductor strand assembly is therefore guaranteed and the individual conductor strands do not need to be transferred from the bundling to a connection level, for example.
  • the coupling module in particular the carrier, expediently has several recesses through which - in the area of the resonance separation point - the conductor sections are carried out without interruption. The conductor sections are therefore not separated.
