Definitions

  • the present invention relates to the general field of electrical cut-off devices, and more particularly those of the pyrotechnic actuation type.
  • Pyrotechnic cutting devices comprising a body in which there is present a pyrotechnic initiator configured to, when triggered, set in motion a piston provided with a relief in the direction of a conductive bar to be cut.
  • FR1908466 which describes a pyrotechnic cutting device.
  • the device presented in the document FR1908466 allows satisfactory results to be obtained, in particular for voltages of intensities up to 18kA and under voltages of the order of 1 kV.
  • the Applicant has noticed that the general performance of the device is limited by the level of electrical insulation obtained after the power cut.
  • the aim of the invention is to provide a cut-off device which ensures more reliable and complete electrical insulation, i.e. making it possible to maintain a complete cut-off of the current in a given time which remains short, and to maintain a high level of electrical insulation after activation of the cut-off device, the high level of insulation being demonstrated by a leakage current of the order of 10 mA for voltages of the order of 2.5 kV, and/or an electrical insulation resistance greater than 80 MOhm.
  • the invention proposes a cut-off device comprising: a conductive element and a movable piston, the piston being able to move between a first position for passing current in the conductive element and a reception when said piston is in its second position, the reception cavity being delimited by at least one internal wall of the reception element, the internal wall being made of electrically insulating material.
  • the receiving element comprises fins made of electrically insulating material and extending inside the receiving cavity projecting from said at least one internal wall of the receiving element.
  • portions made of electrically insulating material, such as plastic for example, and extending in projection inside the receiving cavity of the body of the cut-off device from an internal wall makes it possible to improve the electrically insulating nature of the cut-off device, and more particularly to promote the maintenance of the electrical cut-off once the cut-off device has been actuated.
  • the addition of the fins in the cavity firstly makes it possible to increase the effective surface area of insulating material allowing the dissipation of the energy of the plasma generated following the cutting of the conductive element by the piston, in particular compared to a cylindrical receiving cavity without a portion projecting inwards.
  • the receiving cavity forms a sealed enclosure inside which the plasma of the electric arc is dissipated thanks to the total surface area of insulating material within the receiving cavity.
  • the various elements made of insulating material form energy exchange surfaces allowing the dissipation of the large quantity of energy contained in the electric arc.
  • an electric arc is produced for a short time.
  • the plasma of the electric arc then deposits soot on the walls of the receiving cavity.
  • the conductive element is cut into two sections coupled to the rest of the circuit and not electrically connected to each other. These two sections are spaced apart from each other by a distance that depends on the diameter of the piston and the width of the bar in the case where the piston is circular.
  • the soot deposited on the walls of the receiving cavity can form non-insulating paths that could restore the passage of current between the two sections of the conductive element.
  • the presence of the fins in the cavity makes it possible to increase the length of the soot path between the two sections of the cut conductive element and thus reduce the risk of an electric current being resumed.
  • the device preferably comprises at least six fins to maximize the path traveled by the soot and maximize the material allowing the energy of the plasma created during cutting to be dissipated while minimizing the mass of the cutting device.
  • the fins may comprise a first end integral with said at least one internal wall of the receiving element and a second end which is free inside the receiving cavity, the fins all having the same length between their first end and their second end to maximize the number of fins which can be housed in the receiving cavity while maintaining sufficient distance between the fins.
  • the fins may comprise a first end secured to said at least one internal wall of the receiving element and a second end which is free inside the receiving cavity, the device comprising first fins having a first length between their first end and their second end, and second fins having a second length between their first end and their second end, the second length being less than the first length, each first fin being arranged between two second fins and each second fin being arranged between two first fins.
  • the receiving element may further comprise at least one additional cavity distinct from the receiving cavity and connected to said receiving cavity by at least one channel, said at least one channel being open when the conductive element is broken by the piston.
  • Such a cut-off device comprising at least one additional cavity makes it possible to evacuate the plasma generated during the rupture of the conductive element towards the additional cavity, thus limiting the quantity of plasma in the receiving cavity which tends to slow down the piston and to ensure electrical continuity between the broken ends of the conductive element.
  • the at least one channel can be closed by the piston when said piston is in its second position.
  • the at least one channel can be located at a breaking point of the conductive element.
  • the receiving element may comprise at least two separate additional cavities each connected to the receiving cavity by at least one channel.
  • each additional cavity can be connected to the receiving cavity by at least one channel located at a breaking point of the conductive element, at least one channel being located at each breaking point of the conductive element.
  • said at least one additional cavity may comprise a length at least equal to half the length of the receiving cavity.
  • the volume of said at least one additional cavity may be greater than or equal to the volume of the receiving cavity.
  • said at least one channel can open into the receiving cavity on a portion of said receiving cavity having a conical surface of a shape complementary to a portion of the piston.
  • the device is a pyrotechnic cut-off device comprising a pyrotechnic initiator, the piston being capable of moving following actuation of the pyrotechnic initiator between its first position and its second position.
  • the conductive element may be configured to be ruptured by the piston at two rupture points.
  • the conductive element is configured to be broken at a breaking point and be bent by the piston.
  • a secure electrical installation comprising a cut-off device according to any one of the possible characteristics and an electrical circuit connected to the conductive element of said device.
  • a vehicle comprising a secure electrical installation according to one of the possible characteristics.
  • a cut-off device 100 comprises a body 10 inside which are installed a pyrotechnic initiator 20, a piston 30, and a conductive element 40.
  • the piston 30 is mounted so as to be movable between a first storage position, illustrated in the figure 1 , and a second break position, illustrated in the figure 2 , the piston 30 being moved from its first position to its second position by the actuation of the pyrotechnic initiator 20.
  • the piston 30 has the function of breaking the conductive element 40 during its passage from its first position to its second position, thus cutting off the flow of electric current passing through the conductive element 40.
  • the device 100 comprises a first 41 and a second 42 electrical terminals intended to be connected to an electrical circuit to be cut and which here correspond to two ends of the conductive element 40.
  • the conductive element 40 here takes the form of an electrically conductive bar or tab.
  • the device 100 may comprise a plurality of elements conductors. An example of an installation comprising an electrical circuit connected to terminals 41 and 42 will be described in connection with the figure 4 .
  • the conductive element 40 comprises at least one weak zone 43 which is intended to form a breaking point of the conductive element 40.
  • the conductive element 40 comprises two weak zones 43, thus making it possible to ensure a breakage of the conductive element 40 at two breaking points and to detach a sacrificial portion 44 from the rest of the conductive element 40.
  • the body 10 may have a cylindrical shape with a main axis Z, as illustrated in the figures, other shapes are however possible.
  • the body 10 is formed by a storage element 11 and a receiving element 12 which are assembled together.
  • the storage element 11 has a storage cavity 11a in which the piston 30 is located when the piston 30 is in its first position.
  • the receiving element 12 has a receiving cavity 12a which is aligned with the storage cavity 11a and which communicates with said storage cavity 11a.
  • the receiving cavity 12a is delimited by an internal wall 120 forming an enclosure.
  • the receiving cavity 12a is intended to receive the piston 30 when said piston 30 is in its second position, as illustrated in the figure 2
  • the storage cavity 11a and the receiving cavity 12a form a housing in which the piston 30 can move and which is crossed by the conductive portion 44 of the conductive element 40.
  • the pyrotechnic initiator 20 comprises a pyrotechnic charge connected to connectors 21.
  • the pyrotechnic charge is, when it is initiated for example using a current passing through the connectors 21, capable of generating a pressurizing gas by its combustion.
  • the conductive elements 21 can be connected to a control device C ( figure 4 ) configured to actuate the pyrotechnic initiator 20 when an anomaly is detected.
  • the piston 30 has, in the embodiment illustrated in the figures 1 And 2 , a form of revolution around the Z axis.
  • the Z axis corresponds to the axis of movement of the piston 30 and defines an axial direction D Z .
  • the piston 30 comprises a circumferential groove in which a seal 31, for example an O-ring, is housed.
  • the piston 30 can move in a direction of movement along the Z axis inside the body 10 between a high position (first position) as in the figure 1 , and a low position (second position) as on the figure 2 . As long as the pyrotechnic initiator 20 has not been triggered, the piston 30 is in its first position.
  • the receiving element 12 of the body 10 of the cutting device 100 comprises, in the bottom of the receiving cavity 12a, projecting portions 60 extending inside the receiving cavity 12a.
  • the projecting portions 60 form fins.
  • These fins 60 comprise, in a radial direction D R orthogonal to the axial direction D Z , a first end 61 secured to the internal wall 120 and a second free end 62.
  • the fins 60 thus extend, in the radial direction D R , from the internal wall 120 of the receiving element 12 towards the main axis Z.
  • the fins 60 comprise a first side 63 secured to a bottom wall 122 of the receiving cavity 12a and a second free side 64 intended to be opposite the piston 30 when the receiving element 12 is assembled with the storage element 11.
  • the receiving element 12 further comprises a tip 65 extending in a projecting manner in the axial direction DZ from the bottom wall 122 of the receiving cavity 12a towards the conductive element 40.
  • the tip 65 extends in the axial direction DZ over the entire height of the cavity 12a to bear against a lower face of the conductive element 40 when the receiving element 12 is assembled with the remainder of the cut-off device 100 and the piston 30 is in its first position.
  • the fins 60 extend at most, in the radial direction D R , up to the tip 65.
  • the piston 30 further comprises on its lower part intended to come into contact with the conductive element 40, a central part hollowed out in the axial direction D Z .
  • the piston 30 breaks the conductive element 40 at the two weak zones 43, and the broken portion 44 bends around the point 65, as illustrated in the figure 2 , the piston 30 stopping by pressing on the second side 64 of the fins 60 of the receiving element 12.
  • the fins 60 in the receiving cavity 12a make it possible to increase the effective surface area of insulating material capable of dissipating the energy of the plasma generated when the conductive element 40 is cut by the piston 30.
  • the fins 60 make it possible to increase the length of the soot path between the two cut sections of the sectioned conductive element 40 and thus to reduce the risk of resumption of an electric current following actuation of the cut-off device 100.
  • the fins 60 are preferably made of plastic and may extend in the axial direction DZ only over a portion of the height of the receiving cavity 12a.
  • FIG 4 schematically illustrated is a perspective view of a receiving element of a cut-off device according to a second embodiment.
  • the second embodiment illustrated in the figure 4 differs from the first embodiment illustrated in the Figures 1 to 3 in that, on the one hand, the receiving element 12 does not comprise a tip 65, and, on the other hand, in that the receiving element 12 comprises additional cavities 50 located around the receiving cavity 12a and which are placed in communication with said receiving cavity 12a by channels 51.
  • the plurality of additional cavities 50 thus makes it possible to improve the isolation of the plasma pockets.
  • the receiving element 12 may not comprise an additional cavity.
  • the additional cavities 50 are cavities distinct from the receiving cavity 12a, in particular the piston 30 does not penetrate into the additional cavities 50 when said piston 30 is positioned in the receiving cavity 12a.
  • the channels 51 which connect the additional cavities 50 to the receiving cavity 12a are open when the piston 30 breaks the conductive element 40, and are closed by the piston 30 when said piston 30 is in its second position.
  • Such additional cavities 50 make it possible to receive the plasma generated during the rupture of the conductive element 40, the plasma thus being evacuated from the receiving cavity 12a to the additional cavity(ies) 50 via the channel(s) 51.
  • the Applicant has in fact realized that the fact that the plasma stagnates in the receiving cavity 12a tends on the one hand to slow down the movement of the piston 30, and on the other hand tends to allow the flow of the electric current despite the rupture of the conductive element 40.
  • the fact of moving the plasma out of the receiving cavity 12a thus allows the device 100 to cut off more quickly and more efficiently the flow of an electric current between the two terminals 41 and 42 of the conductive element 40 and this despite the fact that the voltage and the intensity of the electric current are high (in particular a voltage greater than 500V and an intensity greater than 10kA) and cause the generation of plasma at the rupture of the conductive element 40.
  • the piston 30 can then close the channel(s) 51, thus maintaining the plasma in the additional cavities 50, which thus limits the risk that the current continues to flow despite the cutting of the conductive element 40.
  • the channels 51 are located at the level of the face of the receiving element 12 intended to be in contact with the conductive element 40, in other words, at the level of a breaking point of the conductive element 40. This allows better evacuation of the plasma towards the additional cavity(ies) 50. Indeed, the plasma is generated at the breaking point of the conductive element 40.
  • the channels 51 may be located close to a breaking point of the conductive element 40, that is to say at a distance less than or equal to 5 mm from a breaking point of the conductive element 40.
  • the size of the additional cavity(ies) 50 is advantageously sufficiently large relative to the size of the receiving cavity 12a.
  • the additional cavity(ies) 50 have a length that is at least equal to the length of the receiving cavity 12a.
  • the total volume of the additional cavity(ies) 50 is greater than or equal to the volume of the receiving cavity 12a.
  • the total volume of the additional cavity(ies) 50 is greater than the volume of the receiving cavity 12a.
  • the channels 51 open into the receiving cavity 12a on a portion of said receiving cavity 12a which has a conical surface.
  • the shape of the conical surface of the portion of the receiving cavity 12a is complementary to the shape of a portion of the piston 30, thus making it possible to improve the sealing of the closing of the channels 51 by the piston 30.
  • the channels 51 may be located in a lower part of the receiving cavity 12a.
  • FIG. 5 schematically shows an example of a secure electrical installation 300 implementing the cut-off device 100 according to the invention.
  • the secure electrical installation 300 comprises a secure power supply system 310 comprising the cut-off device 100 (shown very schematically) and a power supply circuit 311.
  • the power supply circuit 311 here comprises an electric generator G connected to the second terminal 42 of the conductive portion 40 of the cut-off device 100.
  • the electric generator G may be, for example, a battery or an alternator.
  • the secure power supply system 310 further comprises a control element C configured to actuate the pyrotechnic initiator 20 when an anomaly is detected.
  • the control element C is connected to the pyrotechnic initiator 20 via the connectors 21.
  • the anomaly in response to which the control element C can trigger the pyrotechnic initiator 20 can be an electrical anomaly, such as a current threshold exceeded in the circuit, or a non-electrical anomaly such as the detection of a shock, for example a sudden deceleration of the control element, a change in temperature, pressure, etc.
  • the control element C is able to send an electric current to the pyrotechnic initiator 20 for its triggering in order to cut off the current, as described above.
  • the secure electrical installation 300 finally comprises an electrical device D connected here to the first terminal 41 of the conductive portion 40 of the cut-off device 100 to be supplied by the secure power supply system 310.
  • a motor vehicle may include a secure electrical installation 300.
