Definitions

  • the invention is in the field of electrical equipment, especially equipment for high voltage and direct current electrical networks (HVDC networks for "High Voltage Direct Current”), such as those found on board aircraft such as planes or helicopters or also for AC power grids. It is more specifically interested in switching and / or switching devices, which often have a protection function of a circuit (circuit breakers). These devices can be used with modulated DC or DC (PWM) or alternating current.
  • HVDC networks for "High Voltage Direct Current”
  • PWM modulated DC or DC
  • SSPCs solid state power controllers
  • These components sometimes replace conventional electromechanical devices, and are based on a structure of semiconductor materials. They are much faster than electromechanical devices, since they are able to cut off or turn on the power in a few microseconds, as opposed to a few milliseconds. Moreover, the absence of contact materials and arcing means less wear. Finally, they have finer electrical functions, such as the respect of tripping curves as a function of the evolution of the current in the circuit to be protected or the regulation of the voltage or current. And naturally, they are lighter, which is a major issue in the aeronautics field, and consume less energy, which is also a considerable advantage. Even though their on-state resistance is sometimes quite high, there are semiconductor materials, such as SiC which have a lower resistance and are therefore potentially compatible with the voltages present on the primary circuits.
  • WO97 / 34311 discloses a hybrid cutoff member according to the preamble of claim 1.
  • a hybrid electrical circuit breaking device comprising a static breaking component and an electromechanical breaking component, the static component being fixed on a support carrying electrical contacts for the static component, said carrier being configured to move, upon receipt of a cut-off command, so as to remove its two electrical contacts from their respective pins, thereby forming said electromechanical breaking component.
  • Such a member is particularly easy to integrate in a circuit, and its two components, static and electromechanical, can be controlled in a common, centralized manner. It makes it possible to do without fuse and thus to gain impedance, to program cut-off sequences adapted to the risk situations encountered, and even to manage circuit and network reconfigurations, to overcome faults, for example.
  • the support is configured to move in rotation, which makes it possible to design a compact member that is not very sensitive to external conditions, in particular inclination.
  • the support is configured to move in translation, which allows to design a member that can cut large currents without the wear of the contacts prevents its proper operation.
  • the system may further comprise an electric arc extinguishing system, possibly based on a magnet-polarized breaking chamber, and optionally using a high dielectric strength gas or a quenching in a vacuum.
  • an electric arc extinguishing system possibly based on a magnet-polarized breaking chamber, and optionally using a high dielectric strength gas or a quenching in a vacuum.
  • the static component be configured (or controlled) to cut nominal currents or low currents the electromechanical breaking component being configured (or commanded) to cut short circuit or overload currents and ensure galvanic isolation .
  • the invention also relates to a direct current or alternating current electrical circuit comprising a cut-off device as evoked.
  • the movement of the support is between two contact positions corresponding to two different configurations of the circuit.
  • the invention also relates to a DC or AC electrical network for aircraft comprising an electrical circuit as evoked, the cut-off device being placed in the primary circuit of the network, or in a secondary circuit of the network.
  • an aeronautical electrical network architecture is represented. It involves a generator 10 supplying an AC voltage at 230 V, and a main circuit breaker 20 protecting the downstream of the circuit, first of all an AC / DC converter 30. This converter converts the AC voltage into a DC voltage, for example at 270 V. This is then distributed to three parallel circuits for the supply of three loads 51, 52 and 53. These charges are each protected by a static component type breaking member 41, 42 and 43, and by a fuse 46, 47 and 48, placed in series with the breaking member 41, 42 and 43.
  • Such an architecture is based on a normal operation in which it is the static component that protects the loads, but provides that the fuse allows isolation in case of failure of the static component in order to isolate the fault (load) from the rest of the power grid.
  • Such an architecture has the advantage of having an integrated design, because the fuse can be placed on the printed circuit of the static component, but it implies an increase of the line impedance because of the resistance of the fuse, as well as a risk of tripping slow or inoperative if the short-circuit current is close to the rated current. What's more, if the fuse is to go into action, it it is necessary that an intervention is then carried out to put the circuit back into operation, by replacing the fuse.
  • the invention is presented in connection with the electrical network of the figure 1 , which is DC, but it also applies to an AC power grid.
  • figure 2 there is shown an integrated cutoff member 100 as mentioned in connection with the figure 1 but which solves the difficulties mentioned above.
  • a static component 101 is placed on a rectangular plane support 110 having at its two ends electrical contacts 111 and 112 allowing the passage of an electric current through the static component 101.
  • These contacts 111 and 112 are insertable into two pins 121 and 122 upstream and downstream of the electrical circuit in which the cutoff member is to be inserted. These pins provide the function of electrical contact, but the insertion of the contacts 111 and 112 is reversible, the static component and its support, which constitute the integrated cut-off member 100, thus being plug-in or withdrawable into the electrical circuit.
  • Static component 101 is generally a semiconductor switching component, such as a transistor, a metal-oxide gate field effect transistor (MOSFET) component, an IGBT (insulated gate bipolar transistor), and is preferably encapsulated for its protection.
  • MOSFET metal-oxide gate field effect transistor
  • IGBT insulated gate bipolar transistor
  • An actuator 130 for example an electromagnet, makes it possible to rotate the support 110 around its central point, in its plane, in one direction or the other, thus causing the static component to be plugged in or removed.
  • the actuator 130 receives a control command as a function of the measured current or voltage.
  • Two electrical poles 141 and 142 positioned relative to the pins 121 and 122 at an angle of 90 ° about the axis of rotation can accommodate the electrical contacts 111 and 112 after a 90 ° rotation of the static component and, if these poles are connected to a circuit, to perform a circuit switching, as will be discussed in connection with Figure 8.
  • breaking chambers 151, 152, 153 and 154 comprising for example cutting fins, and a gas mixture promoting the extinction of electric arcs, such as dinitrogen (N2).
  • a system employing a gas with high dielectric strength or a quenching in vacuum can also be used.
  • Polarization is represented in figure 3 , Where the magnetic field was figured that is perpendicular to the support plane 110 of the static component 101, that is to say also perpendicular to the plane of rotation. Precisely a magnetic field B1 has been shown in the breaking chamber 151 between the poles 121 and 142, and a magnetic field B2 in the breaking chamber 153 between the poles 141 and 122. The fields B1 and B2 are in the opposite direction. the other. The electric current arrives as for him by the contact 121, as indicated by the arrows i1 and i2.
  • This figure also shows the movement of the support 110 during the opening of the electromechanical part of the cut-off member.
  • the contact 111 moves from the pole 121 to the pole 142 and the contact 112 moves from the pole 122 to the pole 141.
  • Electric arcs appear between the contact 111 and the pole 121 and between the contact 112 and the pole 122. These arcs are blown and broken in the breaking chambers 151 and 153, thanks to the polarization thereof, as well as the metal fins fragmentation.
  • the arrows 161 and 162 show the direction and the orientation of the blowing of the two electric arcs, or towards the outside of the device.
  • a current is obtained which therefore decreases rapidly, to disappear, in the event that the static component 101 is not actuated, in the space of a millisecond.
  • the invention proposes to actuate the static component 101 after, for example, 100 or 400 ⁇ s, depending on the electrical power involved.
  • Such a sequence makes it possible to dissipate some of the electrical energy in the electric arc. without creating strong erosion of the electrical contacts 121, 111, 122 and 112. It also allows to dimension the static component 101 only to cut currents of limited intensity, which keeps a compact device.
  • the overall cut-off time is short compared to a conventional electromechanical organ, since a factor of 10 can be obtained between the break times usually obtained with conventional electromechanical devices and the hybrid devices presented here and using the evoked sequence.
  • the same integrated cut-off organ 100 presented in figure 2 can also be used to cut nominal currents or very low currents.
  • the control of the device is done in an inverted sequence, because for such currents, the breaking chamber would be inefficient and the cut-off time would be long. So, the command starts by activating the component static 101, then activates the electromechanical part of the system, to ensure the physical sectioning of the electrical circuit.
  • the static component 101 makes it possible to obtain a very short cut-off time. It does not need to be dimensioned too cumbersome, since only weak currents to cut are concerned.
  • the figure 4 presents an aeronautical electrical circuit in which the cut-off device 100 is inserted.
  • the fuse + static component pairs 41, 46 on the one hand, 42, 47 on the other hand and finally 43, 48 are respectively replaced by hybrid cut-off devices 100.
  • the fact that they are plug-in or withdrawable is represented by double arrows.
  • the first of the hybrid switching devices is shown in the switched position, since the contacts are cut off and the support is tilted by 90 °.
  • the hybrid breaking member 100 presented above is based on a support 110 rotating about an axis. It has the advantage that it can be compactly designed and operate reliably under many conditions and orientations.
  • FIG 5 another embodiment of the invention is presented, based this time on a support 510 in translation. It is a hybrid breaking device 500.

Its connections 511 and 512 are electrically contacted with connections 521 and 522 upstream and downstream of the electrical circuit in which the cutoff member is to be inserted. The insertion of the contacts 111 and 112 is reversible.
  • An actuator 530 for example an electromagnet, makes it possible to translate the support 510 perpendicular to the line of the connections 521 and 522, ie also perpendicularly to the line of the contacts 511 and 512, causing the electrical connection or disconnection of the component static.
  • the actuator receives a control command as a function of the current and / or the measured voltage.
  • of the springs 531 and 532 make it possible to make the opening and closing of the electromechanical elastic system to avoid bouncing of the electrical contacts, which could have the disadvantage of creating secondary arcs.
  • the device is preferably positioned vertically, that is to say with the succession spring 531, support 510, spring 532 from top to bottom.
  • Two electrical poles 541 and 542 positioned relative to the pins 521 and 522 at a distance parallel to the axis of translation can accommodate the electrical contacts 511 and 512 after a translation of the static component and its support and, if these poles are connected to a circuit, to perform circuit switching, as will be discussed in connection with the figure 7 .

  • the arcing blowing system is similar to that previously described.
  • This embodiment based on a system in translation is particularly interesting for the breaking of high currents, because in the event of degradation of the surface of the contacts and poles 511, 512, 521, 522, 541 and 542, the contact function will always be assured and the translation always possible.
  • the system is particularly robust even for high powers.
  • FIG 6 an exemplary circuit reconfiguration using cutoff member 500 is shown. Most elements of the circuit of the circuit are recognized again. figure 1 , but the fusible couples + static component 41, 46 on the one hand, 42, 47 on the other hand and finally 43, 48 are respectively replaced by hybrid cutoff devices 500.
  • the reconfiguration presented is carried out in the event of a failure of the control member controlling the cut-off device protecting the load 51 (failure represented by a flash).
  • the cutoff member is then removed, using the electromechanical function of the organ. If the load 51 is a priority system which must be assumed continuity of service, which is not the case of the load 52, then one chooses to use the cutter protecting the load 52 to feed and protect the load 51. This passes through a translation of the load breaking member 52 of the poles 521 and 522 which are placed to bring the current to the load 52, the poles 541 and 542 which are placed to bring, in relief, the current at charge 51.
  • FIG 7 another example of circuit reconfiguration is shown, very similar to that of the figure 6 , but using the hybrid cutoff member 100, based on a rotation.
  • the load 51 is considered a priority, but its breaker is out of order. It is removed by rotating it, then the cutting member supplying the load 52 is also rotated, so that it is no longer in contact with the poles 121 and 122 placed for supplying the load 52, but with poles 141 and 142 placed to supply the load 51 with relief.
  • the invention is not limited to the embodiments presented. In particular, it is not absolutely essential, to apply the principles of the invention to move the two contacts of the support carrying the static breaking component.
  • a system with a rotation about an axis placed at one of the two contacts can also fulfill the functions mentioned, with three poles instead of four.
