    DESCRIPTION
    TECHNICAL AREA
    The invention lies in the field of managing electrical energy flows in an electrical distribution network and, more specifically, in the field of installing sensors for monitoring these flows and the appearance of anomalies. It relates to an installation system for installing a sensor on an overhead power line, an assembly comprising said sensor and said installation system, and a method of installing the sensor on an overhead power line.
    The invention applies in particular to power lines but more generally applies to any overhead line and in particular to any overhead line whose access is difficult or dangerous.
    PRIOR STATE OF THE ART
    Traditionally, electricity distribution networks have been designed with the aim of distributing energy in a unidirectional and relatively homogeneous manner from energy production stations to consumption points. Since the development of decentralized production, also called distributed production, the flows of energy passing through an electrical energy distribution network are more heterogeneous, certain portions of the network being able to undergo a significant energy demand when other portions are subject to lower demand. This results in imbalances in the electrical flows relative to the transfer capacities of the portions of the network. These imbalances can reveal points of weakness on the electrical network.
    In order to control the energy flows on certain sections of an electrical network and to detect any anomalies, sensors can be installed on these sections. Such sensors generally include a voltage measurement device and a current measurement device. They may also include a device for detecting faults such as short circuits. In practice, the sensors are physically installed on the power lines of the network. Each sensor has an attachment element which can take the form of a clamp or a ring in the closed position and which surrounds the electrical line. This attachment element then fulfills a mechanical function by keeping the sensor on the electrical line. The attachment element can possibly fulfill an electrical function by forming an ammeter clamp. The installation of a sensor on an overhead power line poses several difficulties. On the one hand, since the power lines are brought to medium and high voltages, typically between 5000 and 50,000 volts, the safety of the operators installing the sensors must be taken into account. One solution is to electrically isolate the section of power line on which the sensor is installed during the installation time. Such interruption of the flow is however highly undesirable. Another solution is to install the sensors on a live power line using an insulating pole, which electrically isolates the operator from the power line on which he places the sensor. However, operations carried out on live power lines come with strong safety constraints and require the use of qualified technicians for this purpose. Installing the sensors is therefore long and costly. On the other hand, the points of an electrical network on which the sensors must be installed are likely to be located in places difficult of access for the operators and more particularly for the aerial work platforms.
    The aforementioned solutions for installing the sensors on an overhead power line are therefore not entirely satisfactory. An object of the invention is therefore to propose a technique for installing a sensor at a given point on a power line which does not require electrically isolating the section of power line concerned during installation and which does not involve the moving bulky and difficult to move equipment.
    STATEMENT OF THE INVENTION
    To this end, the invention is based on the use of an aerial drone to install the sensor on the desired point of the power line. The use of an aerial drone meets both the operator's safety requirements regarding the risk of electric shock and the need for adaptability to the environment of the power line. In fact, the operator remaining at a distance from the power line when installing the sensor, he is not exposed to the risk of electric shock. The drone can also be driven near a power line almost regardless of its location. In particular, the height of the power line above the ground and the topology of the terrain under the power line have only a very minor impact on its accessibility.
    More specifically, the invention relates to an installation system intended to install a sensor on an overhead line. The overhead line is for example a power line of an electrical distribution network. The sensor comprises for example a voltage measurement device or voltmeter, an electrical intensity measurement device or ammeter and / or a fault detection device on the electrical line. The sensor has an attachment mechanism allowing it to hang onto the overhead line. According to the invention, the installation system comprises:
    an aerial drone arranged to be able to position itself in hovering flight in the vicinity of the overhead line, a support structure arranged to receive the sensor, and a connecting element between the aerial drone and the support structure, the support structure comprising a release mechanism arranged to assume a holding state in which it is able to hold the sensor on the support structure and a release state in which it is able to release the sensor from the support structure.
    In this document, an aerial drone designates any aircraft not carrying a pilot on board. The drone can be flown automatically in whole or in part by a flight management unit or be flown manually by an operator. Preferably, it is a rotary wing aircraft, to allow a hovering or almost hovering flight during the installation operation of the sensor on the overhead line. The drone may have one or more rotors.
    In a first embodiment, the release mechanism comprises a holding element capable of assuming a holding position, in which it is capable of holding the sensor on the support structure, and a release position, in which it is capable of release the sensor from the supporting structure. In the holding position, the sensor must be sufficiently retained on the supporting structure so as not to fall under the effect of vibrations or accelerations due to the flight of the drone.
    According to an advantageous embodiment, the support structure is arranged to receive and maintain at least one given type of sensor without requiring structural modification of this sensor. In particular, a sensor may include a form of attachment arranged to mount the sensor on an insulating pole. The form of attachment consists, for example, of a ring projecting from the body of the sensor. The holding element of the release mechanism may then comprise a rod capable of moving between a holding position, in which it is inserted in the ring, and a release position, in which it is released from the ring. .
    The release mechanism may include a release actuator arranged to move the holding member in the holding position and in the release position. The release actuator comprises for example a servomotor or an electric actuator.
    The installation system may further include a control unit configured to control the release actuator. The control unit can be dedicated to piloting the release actuator or control several organs of the installation system. For example, the control unit can be integrated into the flight management unit ensuring the piloting of the drone. It can be a microcontroller, a microprocessor or a dedicated analog or digital circuit.
    In a second embodiment, the release mechanism comprises an electromagnet arranged to be able to hold or release the sensor as a function of its supply. For example, the electromagnet can be powered to attract a piece of ferromagnetic material secured to the sensor, so as to keep it on the supporting structure, and stop being powered to interrupt the attraction and release the sensor.
    The attachment mechanism of the sensor may include an attachment element capable of assuming an open position, in which it allows the sensor to move freely relative to the overhead line, and a closed position, in which it is capable of attaching the overhead line sensor. The installation system then advantageously comprises an attachment actuator arranged to move the attachment element from the open position to the closed position.
    The hanging mechanism can take different forms. It comprises for example one or more screw-nut assemblies, in which case the attachment actuator comprises a screwdriver adapted to this assembly. It may also include tongues mounted in a pivot connection and which can grip the overhead line by a rotational movement. The latching actuator is then arranged to pivot the tabs.
    In a particular embodiment of the installation system according to the invention, the release actuator and the grip actuator are common. In other words, a single actuator makes it possible to move the holding element of the release mechanism and the attachment element of the attachment mechanism.
    The release actuator and the grip actuator may in particular be common in the case of a clamp-shaped sensor. In such a sensor, the attachment element comprises two articulated jaws and the attachment mechanism further comprises two arms, each arm being integral with one of the jaws and allowing their articulation. The holding element of the release mechanism comprises for example a ring arranged to be able, in the holding position, to grip and retain the arms to maintain the jaws in the open position and, in the release position, to release the arms.
    Advantageously, the jaws return automatically to the closed position by an elastic member such as a helical spring once the arms are released from the ring.
    The installation system may further comprise a proximity sensor arranged to control the latching actuator as a function of a distance between the latching element and the overhead line. More particularly, the proximity sensor can be arranged to control the latching actuator so that it moves the latching element from the open position to the closed position when the distance is less than a threshold distance. The proximity sensor comprises for example a video camera associated with a computer processing unit. The video camera is mounted on the drone or supporting structure and generates images representing the overhead line and the attachment element. The processing unit makes it possible to determine the distance from the images supplied by the video camera. The proximity sensor can also include a laser rangefinder.
    In place of or in addition to the proximity sensor, the installation system may include a contact sensor. The latching actuator is then controlled to move the latching element from the open position to the closed position upon detection of contact with the power line.
    The installation system can optionally include an automatic delay between the attachment and the separation of the supporting structure, in order to guarantee the safest attachment possible.
    The sensor attachment mechanism may also include a latching mechanism arranged to allow the sensor to be hooked to the overhead line by elastic deformation of an attachment element.
    In a particular embodiment, the support structure comprises a housing capable of accommodating all or part of the sensor and opening out through an opening on an external surface of the support structure to allow insertion and removal of the sensor from the support structure by a displacement along an axis of insertion. The housing opens for example on a lower surface of the external structure, to allow its removal under the effect of gravity.
    The housing is for example arranged to accommodate the entire sensor, with the exception of at least part of the attachment mechanism, which protrudes in order to be able to hang on to the power line.
    The installation system may further comprise a mechanical guiding element whose shape and dimensions are arranged so that, when the carrying structure approaches the overhead line in its vicinity along a first axis of translation, it approaches also from the overhead line along a second axis of translation, perpendicular to the first axis of translation, by sliding of the mechanical guide element along the overhead line. The mechanical guide element thus facilitates relative positioning between the sensor attachment mechanism and the overhead line. The mechanical guide element is preferably fixed to the support structure.
    The sensor attachment mechanism is typically arranged to hang on the overhead line by a translational movement along a positioning axis, for example a vertical axis. The mechanical guide element can then comprise two guide vanes extending longitudinally while flaring on either side of the positioning axis. In other words, the guide vanes have a V-shaped cross section. Each guide pallet consists, for example, of a plate.
    In order to assist the positioning of the sensor relative to the overhead line, in particular in the case of piloting at a distance relatively far from the point of installation on the overhead line, the installation system may include electronic devices for guidance assistance . In particular, the installation system may comprise one or more video cameras and a wireless transmission unit arranged to transmit images of the sensor and the overhead line to an operator when the carrying structure is in the vicinity of the overhead line. , so as to allow the operator to visualize a relative positioning of the sensor and the overhead line.
    For example, the installation system may include one or more of the following video cameras:
    a first camera whose optical axis is horizontal in a stable position of the supporting structure, so as to allow an approach of the aerial drone near the overhead line, a second camera whose optical axis is pointed towards the ground in stable position , so as to allow lateral positioning of the sensor with respect to the power line, a third camera whose optical axis is pointed towards the attachment element, so as to allow viewing if the attachment element is sufficiently close to the airline to hang on to.
    The installation system can also be based on other guidance devices such as laser measurement, sonic, or 3D vision.
    In a particular embodiment, the connecting element between the aerial drone and the carrying structure comprises a flexible link connecting the aerial drone to the carrying structure. Such a flexible link makes it possible to mechanically isolate the drone from the overhead line when the carrying structure is in abutment on the overhead line. Thus, movements of limited amplitude of the drone during the installation of the sensor do not disturb this installation. In addition, some drones are equipped with a flight management unit configured to stop the rotation of the drone's propellers or to make it take off again in the event of detection of a ground support. With a rigid link between the drone and the support structure, a support of the support structure on the overhead line could be assimilated as being a support on the ground, which would greatly disturb the installation of the sensor.
    Still in a particular embodiment, compatible with the previous one, the connecting element between the aerial drone and the carrying structure comprises an electrically insulating link connecting the drone to the carrying structure. The drone thus remains electrically isolated from the overhead line even in the event of contact with the carrying structure.
    The invention also relates to an assembly comprising a sensor arranged to be installed on an overhead line and a system for installing this sensor as described above.
    The invention finally relates to a method of installing a sensor on an overhead line. According to the invention, the method comprises the following successive steps:
    mount the sensor on a support structure capable of being moved using an aerial drone, position the support structure near the overhead line, hang the sensor on the overhead line, and release the sensor from the support structure.
    The step of mounting the sensor on the support structure consists for example of coupling the sensor to the support structure by moving the holding element in the holding position.
    In a first embodiment, the step of positioning the supporting structure near the overhead line is carried out by an operator manually piloting the overhead drone.
    In a second embodiment, the step of positioning the support structure near the overhead line is carried out using an automatic guidance device. The automatic guidance device comprises for example one or more of the following devices:
    a satellite positioning system, an inertial unit, a flight management unit on board the drone configured to follow a predetermined flight plan to the drone, a laser rangefinder a 3D display.
    The first and second embodiments can optionally be combined by providing manual piloting in a first flight phase, before entering the vicinity of the airline, and automatic piloting in a second flight phase, after entry. in the vicinity of the airline. Conversely, automatic piloting can be provided in the first flight phase, and manual piloting in the second flight phase.
    The method may further include a detection step in which it is determined that the sensor is near the overhead line, the step of hooking the sensor onto the overhead line being triggered when it has been detected that the sensor is located near the overhead line.

    DETAILED PRESENTATION OF PARTICULAR EMBODIMENTS
    FIG. 1 schematically represents a first example of an assembly 1 comprising a sensor 20 and a system for installing this sensor according to the invention.
    The sensor 20 comprises a body 21 and an attachment mechanism 22 allowing the sensor 20 to be hooked to an overhead line, for example a high voltage line of an electrical distribution network. The attachment mechanism 22 comprises two tongues 221, 222 each capable of pivoting about a horizontal axis to take an open position, in which they allow the sensor to move freely relative to the overhead line, and a closed position, in which they encircle the overhead line to keep the sensor 20 attached to it. The tabs 221, 222 can be rotated by a latching actuator, not shown, which can be mounted on the sensor 20 or on the installation system 30 The latching actuator comprises for example a servomotor. It can be controlled by a control unit integrated in the sensor 20 or in the installation system 30.
    The installation system 30 comprises an aerial drone 31, a support structure 32, a connecting element 35 connecting the drone 31 to the support structure 32 and an electronic guidance assistance system 36. The drone 31 is a wing aircraft rotary equipped with four rotors 311, 312, 313, 314. Any other aircraft allowing a hover could nevertheless be used as a drone. The support structure 32 is arranged to receive the sensor 20. It is in the form of a nacelle comprising a housing 321 in which the sensor 20 can be housed and an opening 322 opening onto a lower surface 32A of the support structure 32. The support structure 32 further comprises a release mechanism 33 arranged to alternately be able to hold the sensor 20 in the housing 321 or release it from the support structure 32. The release mechanism 33 comprises a holding element 331, a release actuator 332 and a control unit 333. The holding element 331 consists of a tab or a rod capable of being positioned in a holding position or in a release position. In the holding position, shown in Figure 1, it is positioned in front of the opening 322, so as to retain the sensor 20 in the housing 321. In the release position, it is removed from the opening 322, so to leave the sensor free. The release actuator 332 is arranged to move the holding member in the holding position and in the release position. It includes for example a servomotor. The control unit 333 is configured to control the release actuator 332. It consists, for example, of a microprocessor configured to generate a release control instruction as a function of a signal received by an operator or by a sensor, for example a proximity sensor. The electronic guidance assistance system 36 comprises a first video camera 361 and a second video camera 362. The video cameras 361, 362 generate images transmitted to an operator or to an automatic piloting device, so as to allow the positioning of the sensor 20, and in particular its attachment mechanism, relative to the overhead line. In order to allow positioning according to the three dimensions of the space, the video camera 361 is pointed towards the ground and the video camera 362 is pointed towards the attachment mechanism 22, along a horizontal axis. Preferably, the optical axis of the video camera 362 is parallel to the axis along which the attachment mechanism 22 allows attachment to the overhead line.
    Figures 2 and 3 show a second example of assembly 4 comprising a sensor 50 and an installation system 60 of this sensor according to the invention. In FIGS. 2 and 3, the drone is not shown, the connecting element being only partially shown in FIG. 3. In FIG. 2, the sensor 50 is separated from the installation system 60 and on the Figure 3, it is mounted in the installation system 60.
    The sensor 50 comprises a body 51, a hooking mechanism 52 and a retaining ring 53. The body 51 has a cylindrical shape. The attachment mechanism 52 is mounted at a first longitudinal end of the body 51. It comprises two tongues 521, 522 projecting with respect to the body 51. Each tongue 521, 522 is mounted in pivot connection around a horizontal axis and can take an open position, as shown in Figures 2 and 3, and a closed position, in which they are folded against the sensor 50, so as to surround the overhead line. The retaining ring 53 is mounted at a second longitudinal end of the body 51 projecting from the body 51 in a direction opposite to the first end.
    The installation system 60 comprises a drone, not shown, a support structure 62 and a connecting element 65 connecting the drone to the support structure 62. The support structure 62 is generally in the form of a cylindrical body 621 in which is formed a housing 622 opening onto a lower external surface 621A of the body 621 by an opening 623. The housing 622 is shaped to receive the sensor 50 through the opening 623. The installation system 60 further comprises a latching actuator 66 mounted on the supporting structure 62. The latching actuator 66 is arranged to move the tongues 521, 522 from the open position to the closed position. It includes for example a booster. The carrying structure 62 further includes a release mechanism 63 arranged to be able to alternately hold the sensor 50 in the housing 622 or release it from the support structure 62. The release mechanism 63 comprises a rod, not shown, and a release actuator 632. The rod is able to assume a holding position, in which it is inserted into the holding ring 53 of the sensor 50 when it is positioned in the housing 622, and a release position, in which it is removed of the holding ring 53. The release actuator 632 is arranged to be able to move the rod between the holding position and the release position. It includes for example a booster.
    The support structure 62 further includes a mechanical guide assembly 67, shown in FIG. 3, arranged to assist in guiding the support structure 62 and the sensor 50 in the final approach phase. The mechanical guide assembly 67 comprises a first rod 671 and a second rod 672, a first centering frame 673, a second centering frame 674, a third centering frame 675 and a fourth centering frame 676. The first rod 671 and the second rod 672 extend laterally and in opposition to each other from the body 621 of the support structure 62. They form a support element for the centering frames 673-676. The centering frames 673, 674 are arranged symmetrically relative to the body 621, each at one end of a rod 671, 672. The centering frames 675, 676 are arranged symmetrically relative to the body
    621, closer to the body 621. The centering frames 673-676 are each formed from a set of parts having generally a V-section in a plane perpendicular to the axis of the rods 671, 672, the point of the V starting from one of the rods 671, 672. Such an arrangement makes it possible to facilitate the positioning of the sensor 50 relative to the overhead line on which the sensor 50 is to be installed. The centering frames 673, 674 have larger dimensions than the centering frames 675, 676. The frames 673, 674 thus make it possible to position the sensor approximately from a relatively distant distance, while the frames 675, 676 allow more positioning end of sensor in final approach phase.
    The connecting element 65 is partially shown in FIG. 3. It comprises an arm 651 extending vertically from the body 621 of the support structure 62, a rod 652 extending horizontally and a T-connector 653 connecting the arm 651 to the rod 652. The rod 652 is parallel to the rods 671, 672 of the mechanical guide assembly 67. Such parallelism is however not essential. Each end of the rod 652 is provided with an attachment point 654, 655, arranged to attach a wire connecting the rod 652 to the drone. The wire has for example a length of between 10 centimeters and 2 meters. It forms a flexible and electrically insulating link between the supporting structure 62 and the drone.
    FIG. 4 represents a third example of assembly 7 comprising a sensor 80 and an installation system 90 for this sensor
    The sensor 80 forms a clamp. It comprises two jaws 81, 82 hinged together, and two arms 83, 84, each arm extending from a jaw. The jaws are arranged to be able to take an open position, in which they define an open contour, and a closed position, in which they define a closed contour. The sensor 80 further comprises an elastic member returning the jaws to the closed position at rest, that is to say in the absence of external force.
    The installation system 90 comprises a drone, not shown, a support structure 92 and a connection element 95. The connection element 95 is substantially identical to the connection element 65 of the installation system 60 shown in the figure 3. The support structure 92 essentially comprises a guide shaft 921 and a support plate 922. The guide shaft 921 is fixed on the arm 651, in its extension. It forms a guide support in translation for a ring 96 capable of enclosing the arms 83, 84 of the sensor 80 to maintain the clamp in the open position. The carrier plate is mounted on the arm 651. It carries a servomotor 93 connected to the ring 96 by a control rod 97. The servomotor 93 can move the ring 96 towards the free end of the guide shaft 91, so that the ring maintains the clamp in the open position, and in the opposite direction, so as to release the arms 83, 84 and thus close the jaws 81, 82. The servomotor 93 thus acts both 'release actuator and attachment actuator.
    The support structure 92 further comprises a mechanical guide assembly 98 comprising two pallets 981, 982 fixed to the guide shaft 91 by connecting pieces 983, 984. The pallets 981, 982 have a V-section in a plane containing the longitudinal axis of the guide shaft 91.
    FIG. 5 represents an example of steps of a method for installing a sensor on an overhead line. The sensor can be one of the sensors described with reference to FIGS. 1 to 4. The method 100 comprises the following successive steps:
    a step 101 in which the sensor is mounted on a support structure capable of being moved using an aerial drone, a step 102 in which the support structure is positioned near the overhead line, a step 103 in which the sensor is hung on the overhead line, and a step 104 in which the sensor is released from the supporting structure.
