Definitions

  • the present invention relates to a connection configuration unit for providing electrical connection.
  • electrical connection are typically configured according to a command. Such commands are often applied by one or several relay(s). Changing a configuration may require several contacts to be opened, and several other contacts to be closed. In certain applications in order to ensure electrical continuity, it is typically preferred that the new contacts are closed before opening the old ones in order to ensure electrical continuity, i.e. avoiding interruption of the current. This process is often referred to as "make-before-break".
  • the switching equipment which is in charge of switching from one connection configuration to another typically has to deal with high voltages (up to 15 KV) and potentially high in-rush currents.
  • the switching operation at such high voltage and current values typically requires very reliable, and therefore expensive equipment. Otherwise the switching equipment would not be able to last an operation life in submerged conditions which is typically on the order of 25 years.
  • a supplementary position may be required with any of the inputs electrically connected with any of the outputs. In such situation all the inputs may be connected to all the outputs.
  • connection configuration units providing the possibility of performing make-before break connections are known in the related art.
  • European patent number EP1455462 relates, in brief terms, to a branching unit with reconfigurable terminal connections comprising a fixed part and a mobile part.
  • the fixed part includes three connection terminals (A, B, C) and the mobile part includes three connection terminals (E1, E2, E3) which are located on a rotatable body (a rotor).
  • the mobile connection terminals have respective first conductive part and the fixed connection terminals have respective second conductive parts.
  • the mobile first conductive parts and the fixed second conductive parts are configured to provide electrical contacts according to different configurations as desired.
  • the rotation of the rotor causes the mobile connection terminals E1, E2 and E3 to move to a new connection position thereby providing a new configuration (or reconfiguration) for the connections between the fixed terminals and mobile terminals.
  • lengths of said mobile first conductive parts are greater than distances between said second conductive parts. This latter feature allows for providing a make-before-break performance by the device.
  • EP1455462 provides satisfactory solutions for certain requirements such as for example protection against accidental reconfiguration and hot switching and simplifies the reconfiguration procedures.
  • the electronic circuitry e.g. circuits 20 and 20'
  • the electronic circuitry for ensuring electrical continuity are located on the mobile support 8 (or the rotor).
  • EP1455462 relates to integrating electronic circuits inside the device and provide them with the necessary links with the external (non rotating) elements of the system and the functions of relay and circuitry are integrated in the device. This gives rise to a complex system which typically may require a relatively large size.
  • connection configuration unit for reconfiguring electrical or electronic circuits with a relatively low or minimum number of components - thus less complex -, capable of using simple commands for such reconfiguration and providing high reliability, while such reconfiguration may be performed in an efficient manner.
  • connection configuration unit comprising a fixed part and a mobile part, the fixed part comprising at least three fixed input terminals and at least three fixed output terminals, the mobile part being moveable with respect to the fixed part from a first connection position to a second connection position wherein the mobile part comprises at least three connection sets each connection set comprising respectively an input terminal, an output terminal and a electrical connection path between said input terminal and the said output terminal; wherein each of said at least three connection sets is configured to allow electrical connectivity at said first connection position between a first fixed input terminal and a first fixed output terminal and to allow electrical connectivity at said second connection position between a second fixed input terminal and a second fixed output terminal.
  • an angular order of respective positions of at least a first, a second and a third mobile input terminals on the mobile part are different from an angular order of respective positions of a first, second and third mobile output terminals on the mobile part.
  • connection configuration unit is adapted to provide the first connection configuration and the second connection configuration simultaneously.
  • connection configuration unit is adapted to provide electrical connection between first, the second, the third, the fourth, the fifth and the sixth input terminals and the first, the second, the third, the fourth, the fifth and the sixth output simultaneously.
  • the mobile part is configured to adopt at least three stable positions each stable position corresponding to a respective connection configuration.
  • the at least first, second and third mobile input terminals on the mobile part are provided in a clockwise order and the at least first, second and third mobile output terminals are provided in counter-clockwise order, or vice-versa.
  • Some embodiments feature a branching unit comprising the connection configuration unit as described herein.
  • branching unit further comprising a configuration driver unit adapted for providing said activation command to said mobile part.
  • Figures 1 a and 1b are exemplary schematic representations of a connection configuration unit 1 according to some embodiments.
  • the connection configuration unit 1 comprises a fixed part 11 and a mobile part 12.
  • the terms mobile part and fixed part are to be understood relative to each other; namely, the mobile part being capable of performing movements with respect, or relative, to the fixed part as will be described in further detail below.
  • the term "fixed part” is to be understood relative to the external elements of the system such as for example support of the component and the like.
  • the fixed part 11 comprises input terminals A, B, C and output terminals A', B', C' providing respective input and output connection points for the connection configuration unit 1.
  • input terminals and output terminals are used in this description for the sake of better understanding the structure and the operation of the unit; whereas in practice the unit itself may operate bi-directionally and therefore, input terminals may also be used as output points and vice-versa.
  • Any elements or bodies on the fixed part and the mobile part used for supporting electric terminals may be made of an insulating material (for example glass or ceramic) and may preferably be made in cylindrical shape as represented in the bottom and top views of figures 1 a and 1 b. However this is only exemplary and other appropriate materials and shapes may also be used within the scope of the claimed invention.
  • the mobile part 12 may be made to move by means of a moving mechanism (not shown).
  • the movement of the mobile 12 part may be rotational around an axis, for example around the central axis R as shown in figure 1b .
  • the moving mechanism may preferably be a stepper motor, which in response to an activation command causes the mobile part (e.g. a rotor) 12 to rotate around axis R at a predefined angle.
  • Means for activating the mobile part may also be used such as for example linear translation steps provided by solenoid(s).
  • Figures 2a and 2b show schematic representations of connections provided by the connection configuration unit 1 in a first connection configuration position.
  • Figure 2a shows the structure of the input terminals A, B, C with respect to the mobile part 12 (only represented by means of electrodes and support bodies as will be described further below).
  • the input terminals A, B, C of the fixed part 11 each comprise respective fixed input electrodes 11A, 11B and 11C which extend inside the insolating body of the fixed part 11.
  • These electrodes may be made in any appropriate shape for example in the form of two spring-blade electrodes extending at two side of the respective terminals inside the body of the fixed part 11.
  • the mobile part 12 is represented - for the purpose of simplification - by means of mobile input electrodes X, Y and Z which are located on support bodies 12X, 12Y and 12Z.
  • the support bodies 12X, 12Y and 12Z are shown in the form of respective arms.
  • this representation is provided only for illustration purposes and the mobile input electrodes X, Y and Z may be on any suitable support body and in any appropriate shape.
  • Figure 2b shows the structure of the output terminals A', B', C' with respect to the mobile part 12 (here again only represented by means of electrodes and support bodies).
  • the output terminals A', B', C' of the fixed part 11 each comprise respective fixed output electrodes 11A', 11B' and 11C' which extend inside the insulating body of the fixed part 11.
  • These electrodes may be made in any appropriate shape for example in the form of two spring-blade electrodes extending at two side of the respective terminals inside the body of the fixed part 11.
  • the mobile part 12 is represented in figure 2b by means of mobile output electrodes X', Y' and Z' which are located on support bodies 12X', 12Y' and 12Z' (which in analogy to figure 2a may be on any suitable support body and in any appropriate shape).
  • Mobile input electrodes X, Y and Z of the mobile part 12 are configured to enter into electrical contact with at least one of the fixed input electrodes 11A, 11 B and 11C (not necessarily in that order) of the fixed part 11.
  • electrode X is connected to electrode 11A
  • electrode Y is connected to electrode 11B
  • electrode Z is connected to electrode 11C.
  • mobile output electrodes X', Y' and Z' of the mobile part 12 are configured to enter into electrical contact with at least one of the fixed output electrodes 11 A', 11 B' and 11 C' (not necessarily in that order) of the fixed part 11.
  • electrode X' is connected to electrode 11A'
  • electrode Y' is connected to electrode 11C'
  • electrode Z' is connected to electrode 11 B'.
  • mobile electrodes X and X' of the mobile part 12 are coupled to each other by means of an electrical connection path PX
  • mobile electrodes Y and Y' of the mobile part 12 are coupled to each other by means of an electrical connection path PY
  • mobile electrodes Z and Z' of the mobile part 12 are coupled to each other by means of an electrical connection path PZ.
  • the connection paths are made permanently on the body of the mobile part.
  • connection paths are made of high voltage insulated wires.
  • the angular order of the respective positions of the mobile input electrodes X, Y and Z on the body of the mobile part 12 are different from the angular order of the respective positions of the mobile output electrodes X', Y' and Z'. This is because a different angular position of the input electrodes with respect to those of the output electrode allows for changing connection configurations between the input terminals A, B, C and output terminals A', B', C' by rotation of the mobile part 12.
  • the mobile input electrodes X, Y and Z are disposed in clockwise order; whereas the mobile output electrodes X', Y' and Z' are disposed in counter-clockwise order.
  • the mobile input electrodes X, Y and Z are disposed in counter-clockwise order; whereas the mobile output electrodes X', Y' and Z' are disposed in clockwise order.
  • the electrodes are interconnected.
  • mobile input electrodes X, Y and Z are respectively interconnected to mobile output electrodes X', Y' and Z' through connection paths PX, PY and PZ respectively. Therefore, the effective link between input and output terminal depends on the angles between relative positions of X and X', between Y and Y', between Z and Z'. Such different angles allow for changing the connection configuration by the rotation of the mobile part.
  • clockwise and counter-clockwise disposition of the electrodes as mentioned above related to a structure with three input terminals and three output terminals may also be used for higher number of input and output terminals.
  • other dispositions are also possible and may be designed according to specific applications.
  • the unit 1 provides connectivity between input terminal A and output terminal A', between input terminal B and output terminal C' and between input terminal C and output terminal B'.
  • Figures 3a and 3b are exemplary schematic representations of connections provided by the connection configuration unit of figures 1 a and 1 b (or 2a and 2b) in an intermediate connection configuration position.
  • connection configuration unit of figures 1 a and 1 b or 2a and 2b in an intermediate connection configuration position.
  • like elements are shown with like reference numerals as those of figures 2a and 2b respectively.
  • the position of the mobile part shown in figures 3a and 3b relates to one in which the mobile part 12 has made a rotation at a certain angle with respect to the position of the mobile part shown in figures 2a and 2b .
  • the angle of rotation is about 60 degrees ( i.e . 1/6 of a complete turn).
  • the mobile input electrode X which was already in contact with the fixed input electrode 11A enters additionally into electrical contact with the fixed input electrode 11 B, thereby maintaining contacts with both fixed input electrodes 11A and 11B.
  • the mobile input electrode Y which was already in contact with the fixed input electrode 11B enters additionally into electrical contact with the fixed input electrode 11C, thereby maintaining contacts with both fixed input electrodes 11B and 11C; and the mobile input electrode Z which was already in contact with the fixed input electrode 11C enters additionally into electrical contact with the fixed input electrode 11A, thereby maintaining contacts with both fixed input electrodes 11C and 11A.
  • This position allows each mobile input electrodes to make a new contact with a new fixed input electrode before breaking its respective contact with the previous fixed input electrode, thereby performing the so-called make-before-break process.
  • Figure 3b shows the situation of the output contacts after the rotation performed as described in relation to figure 3a . Therefore, after said rotation the mobile output electrode X' which was already in contact with the fixed output electrode 11A' enters additionally into electrical contact with the fixed output electrode 11B', thereby maintaining contacts with both fixed output electrodes 11A' and 11B'. Likewise, the mobile output electrode Y' which was already in contact with the fixed output electrode 11 C' enters additionally into electrical contact with the fixed output electrode 11A', thereby maintaining contacts with both fixed output electrodes 11C' and 11A'; and the mobile output electrode Z' which was already in contact with the fixed output electrode 11B' enters additionally into electrical contact with the fixed output electrode 11C', thereby maintaining contacts with both fixed input electrodes 11B' and 11C'.
  • Figures 4a and 4b are exemplary schematic representations of connections provided by the connection configuration unit of the previous figures in a second connection configuration position.
  • like elements are shown with like reference numerals as those of the previous figures respectively.
  • the position shown in figures 4a and 4b relates to one in which the mobile part 12 has made a further rotation at a certain angle with respect to the position shown in figures 3a and 3b .
  • the angle of rotation is about 60 degrees ( i.e . a further 1/6 of a complete turn).
  • the mobile input electrode X loses contact with the fixed input electrode 11A and maintains electrical contact with the fixed input electrode 11B.
  • the mobile input electrode Y loses contact with the fixed input electrode 11B and maintains electrical contact with the fixed input electrode 11C; and the mobile input electrode Z loses contact with the fixed input electrode 11C and maintains electrical contact with the fixed input electrode 11A.
  • This position provides a new connection configuration which is different from the first connection configuration of figure 2a .
  • Figure 4b shows the situation of the output contacts after the rotation performed as described in relation to figure 4a . Therefore, after said rotation the mobile output electrode X' loses contact with the fixed output electrode 11 A' and maintains electrical contact with the fixed output electrode 11 B'. Likewise, the mobile output electrode Y' loses contact with the fixed output electrode 11 C' and maintains electrical contact with the fixed output electrode 11A'; and the mobile output electrode Z' loses contact with the fixed output electrode 11 B' and maintains electrical contact with the fixed output electrode 11 C'. This position provides a new connection configuration which is different from the first connection configuration of figure 2b .
  • the unit 1 provides connectivity between input terminal A and output terminal C', between input terminal B and output terminal B' and between input terminal C and output terminal A'.
  • the unit is made to reconfigure the connections from the first connection configuration to the second connection configuration.
  • connection configuration unit 1 may be configured to perform further rotations at appropriate angles. Such rotations may be performed in similar fashion as described above in relation to changing from the first connection configuration to the second connection configuration.
  • FIG. 5 schematically illustrates an arrangement of connections provided with a connection configuration unit 1 comprising more than three input terminals and more than three output terminals according to some embodiments.
  • connection configuration unit 1 comprising more than three input terminals and more than three output terminals according to some embodiments.
  • FIG. 5 there is provided an illustration of five different configurations interconnecting five input terminals A, B, C, D, E with five output terminals A', B', C', D', E' using five interconnections namely VV', WW', XX', YY', ZZ'.
  • connection configuration unit which is capable of performing switching operations under high voltages (up to or exceeding 10 KV) with a simplified structure and low cost as compared to known solutions.
  • the particular structure of the architecture allows for long lasting operation in submerged conditions with improved reliability.
  • Using a stepper motor may simplify managing relatively long (in centimeter range) distances for insulation, as the rotation generates displacements in centimeter range whereas an electromagnet as is typically used, generates only displacements in the range of millimeters.
