    [0001] The present invention relates to a detector of at least one electrical magnitude in an electrical conductor, as well as an overhead electrical power distribution network comprising such a detector. In the field of overhead electricity distribution networks, one of the major responsibilities for the companies in the sector is to ensure the operation of the network and to minimize the number of power interruptions. When an interruption occurs in the distribution, in order to restore the power supply as quickly as possible, it is necessary to identify and locate the fault. In addition, a very common disadvantage in the distribution is a phase shift of the current with respect to the voltage that may occur along the transmission line. In this regard, it is known to use, in an air network, fault detectors installed on the transmission lines of the air network. Their commissioning can take place when the distribution network is in operation, that is to say when the transmission lines carry a current of medium or high voltage. In the same way, the maintenance of the detectors is carried out in a network operating situation. Commissioning and maintenance of these detectors are difficult and dangerous procedures. It is therefore important to provide a detector that is easy to install, reliably. In particular, its attachment to the transmission lines must be sustainable, producing a significant closing force and independent of the diameter of the network conductor on which it must be hooked, and require little control from operators.
    [0002] The detection of a fault is performed with a measurement of the current and an estimate of the phase difference between the current and the voltage transmitted by the line. The detector thus comprises sensors or electronic components that need to be electrically powered. In this regard, it is known from WO-A-2010/042565 to use a magnetic toroid to supply electrical energy to the sensors and the electronic components of the detector. According to this approach, the magnetic core is closed around the electrical conductor of the transmission line and is configured to induce an electric current in the turns of a coil wound around the magnetic core. It is also known, for example from US-A-2008/0077336, to install a detection device on a high-voltage line, this device comprising a magnetic power supply core for a computer, the computer being configured to process the parameters. measured by the detector and transmit them to a concentrator by a radio communication. Finally, it is known from WO-A-2012/021478, to use a system of clamps and magnetic core to install a detector on a transmission line of an overhead network and to supply the electrical sensors of the detection device. The clamps close around the electrical conductor through a screw / nut system. This requires the operators to turn the screw of the screw / nut system with a pole, which is long, tiring and potentially dangerous. Finally, a good hanging depends on a good tightening on the part of the operator.
    [0003] It is to these drawbacks that the present invention more particularly intends to remedy by proposing a new detector in which the installation is secured, in particular thanks to an innovative fastening system. To this end, the invention relates to a detector of at least one electrical magnitude in an electrical conductor, the detector comprising a frame on which is fixed a mechanical block. The mechanical block includes a magnetic core, divided into two branches movable in rotation about an axis defined by the frame, between a spaced position and a closed position around the electrical conductor, the magnetic core having a coil wound around at least one of the two branches. The mechanical block also comprises a current sensor, divided into two branches movable in rotation around an axis defined by the frame, between a first spaced position and a closed position around the electrical conductor, the current sensor performing a current measurement. alternative. The mechanical block also includes a rotational force transmission element to the magnetic core and the current sensor, this element being provided with at least one portion able to receive the conductor in abutment, and at least two anchoring clamps of the detector on the electrical conductor, each clamp being movable in rotation, about an axis parallel to the axis of rotation of the branches of the magnetic core and defined by the frame, between an open position and a locked position of the clamp. The detector also comprises a base, and at least one electronic device capable of transmitting a parameter of the current detected by the current sensor. According to the invention, the force transmission element is extended by a trigger, while each anchor has a portion in contact with the trigger and carries a protruding member in a direction parallel to its axis of rotation this protruding member being movable with the clamp between its open position and its locked position. In addition, a spring is stretched between the protruding member and a fixed part to the frame. This spring exerts a torque on the clamp and tends to move it to its open position or to its locked position depending on the angular position of the clamp relative to the axis of rotation. In addition, between the open position and the locked position, the gripper passes through a neutral position where the projecting member, its axis of rotation and the fixed part are aligned and the spring does not exert a torque on the gripper. .
    [0004] Thanks to the invention, the anchoring clamps provide a permanent closure on the electrical conductor, regardless of its diameter. Springs produce constant, operator-independent clamping forces for the attachment system as well as for the measuring and self-feeding system. In addition, the invention provides an architecture of the detector that closes the mechanism block in a single operation, the strokes of the clamps, the torus and the current sensor being independent of one another. The commissioning of the detector is carried out using a standard pole and provides advantages in terms of time, fatigue and even feasibility compared to the solutions of the prior art. Self-feeding also makes it possible to carry out measurements at all times and to periodically communicate the measured quantities to a control center and thus to offer in parallel a powerful control system. According to advantageous but non-obligatory aspects of the invention, such a detector may incorporate one or more of the following features, taken in any technically permissible combination: - When in its locked position, each clamp is in contact with the electrical conductor which constitutes a locking end stop for each clamp, regardless of its diameter. - When in the closed position, the branches of the magnetic core and the branches of the current sensor are supported against each other, regardless of the diameter of the electrical conductor. - The radial distance between the axis of rotation of a clamp and the protruding member is at least two times smaller than the radial distance between the axis of rotation of the clamp and the fixed part to the frame. - The detector comprises a cowling system comprising two covers that surround the mechanism block and are movable with it to close around the conductor, while the detector includes at least one elastic return member of the magnetic core and at least one member resilient return of the rollover system to their respective closed positions around the electrical conductor. - The current sensor is integral with the magnetic core. The mechanism block is provided with two pairs of clamps for anchoring the detector on the electrical conductor, these pairs of clamps being disposed on either side of the magnetic core, along the axis of rotation of one of the his branches. - The current sensor is a Rogowski winding. The electronic device comprises a voltage sensor whose potential is taken up by the anchoring clamps and an electronic card provided with a computer for processing an output signal of the voltage sensor and generating a radio signal on the basis of this signal. The invention also relates to an overhead electrical power transmission network comprising three transmission lines, each line being composed of an electrical conductor and provided with a detector of at least one parameter of an alternating current in the electrical conductor, and a concentrator adapted to receive radio signals emitted by the detectors and configured to process these radio signals. This network is characterized in that at least one detector is as mentioned above.
    [0005] The invention will be better understood and other advantages thereof will appear more clearly in the light of the following description of an embodiment of a detector and an air network in accordance with its principle, given in FIG.

    [0006] The medium voltage overhead network 10 is shown in FIG. 11 and comprises three transmission lines L10A, L1OB and L100, each line being composed of an electrical conductor 100. Each transmission line L10 is equipped with a detector 1 of FIG. at least one parameter of an alternating current flowing in the electrical conductor 100, the detector being configured to transmit radio signals Si. The overhead network 10 is also equipped with a concentrator 104, able to receive the radio signals emitted by the detectors 1 and configured to process these radio signals. If when the hub 104 has analyzed the data sent with the radio signals Si, it transmits the results to a control center 106 through a wired connection line 108 or via long-range radio signals. The concentrator 104 can also transmit S104 control radio signals to the detectors 1. In another embodiment of the invention, the functions of the concentrator 104 are performed by one or each detector 1. The detector 1, shown in FIGS. FIGS. 1 to 10, is a device for detecting at least one parameter of an alternating current in the electrical conductor 100. This parameter can be the phase, the intensity or the voltage flowing in the conductor 100 of a line L10 . This detector 1 comprises a rollover system 5 comprising two covers 50A and 50B rotatable, around two parallel axes X51A and X51B defined by the detector 1, between an open position and a closed position around the electrical conductor 100. Note 500A and 500B the contact surfaces of the covers 50A and 50B. When the system 5 is closed, the surfaces 500A and 500B are pressed against each other. Each cap 50A and 50B is provided with a handle 502A and 502B and an inner finger 504A and 504B. The cowling system 5 is fixed on a base 4 which is provided with two lateral wings 40A and 40B which allow the covers 50A and 50B to slide during the opening. The base 4 also comprises two flanges 42 for lateral guidance of the covers 50A and 50B and an anchor ring 44 shown only in Figures 1 and 6, for clarity of the drawing. The shroud system 5 surrounds an electronic device 6. The electronic device 6 comprises a voltage sensor and an electronic card provided with a computer, the computer processing an output signal of the current and / or voltage sensors and generating a signal radio based on these signals. Only the envelope of the electrical device 6 is visible in Figures 4 and 5, its components not being shown for clarity of the drawings. The cowling system 5 also surrounds a frame 2 comprising a plate 20 and two bearings 21 which protrude perpendicularly to the plate 20. The bearings 21 support a mechanism block 200. The mechanism block 200 includes a magnetic core 22, a coil 24 , a current sensor 26, a cover 27 and a force transmission element 28. The mechanism block 200 also includes two pairs of clamps 3. The magnetic core 22 is divided into two branches 22A and 22B, these branches being rotatable, about a common axis X2 defined by the frame 2, between a spaced position and a closed position around the electrical conductor 100. 220A and 220B are noted the contact surfaces of the branches 22A and 22B. When, the torus 22 is closed, the surfaces 220A and 220B are in abutment against each other. The coil 24 is wound around the branch 22A of the magnetic core 22. The current sensor 26 is divided into two branches 26A and 26B, the branches being rotatable, about the axis X2, between a spaced position and a position closed around the electrical conductor 100. The contact surfaces of the branches 26A and 26B are marked 260A and 260B. When the sensor 26 is closed, the surfaces 260A and 260B bear against each other. The current sensor 26 performs a measurement of the alternating current. In the example of the figures, the sensor 26 is a Rogowski winding. Alternatively, it may be conventional ferro-magnetic sensors. The magnetic core 22 is integral with the current sensor 26 via the cover 27 which surrounds them. In particular, the branch 22A of the magnetic core 22 is integral with the branch 26A of the current sensor 26, in rotation about the axis X2, via a branch 27A of the cover 27 while the branch 22B of the magnetic core 22 is integral with the branch 26B of the current sensor 26, rotating about the axis X2, via a branch 27B of the cover 27. The two branches 27A and 27B are attached to a bar 270 which extends between the two bearings 21 parallel to the plate 20 of the frame 2. In particular, the axis X2 of rotation of the magnetic core 22 and the current sensor 26 is defined by the longitudinal axis of this bar 270.
    [0007] There is 280 a central body of the element 28 of force transmission. The central body 280 of the force transmission element 28 comprises two shafts 280A and 280B. Two springs 286 are stretched between the shafts 280A and 280B. The central body 280 is delimited on two sides by two portions 282, able to receive in abutment the electrical conductor 100. Each portion 282 is extended axially, opposite the shafts 280A and 280B, by a trigger 284. The element 28 is configured to transmit a rotational force to the branches 27A and 27B of the cover 27. The cover 27, which surrounds and makes integral the magnetic core 22 and the current sensor 26, then transmits the rotational force to the branches 22A and 22B and than branches 26A and 26B.
    [0008] The pairs of clamps 3 are arranged on either side of the force transmission element 28, along the axis X2 of the frame 2. The pairs of clamps 3 each comprise two clamps 30A and 30B. Each clamp 30A is rotatable, about an axis X30A defined by the frame 2, between an open position and a locked position on the conductor 100. Also, each clamp 30B is movable, in rotation about a defined axis X3OB by the frame 2, between an open position and a locked position on the conductor 100. The clamps 30A and 30B are each provided with a portion 32A and 32B which bears against the trigger 284 of the transmission element 28. effort. In addition, the clamps 30A and 30B each carry a member 34A and 34B projecting in parallel axes X30A and X3OB, in a direction parallel to the axis of rotation respectively X30A and X3OB. The protruding members 34A and 34B are movable with the clamps 30A and 30B during their displacement between their open position and their locked position on the conductor 100. The axes X30A and X3OB respectively correspond to the longitudinal axes of the shafts 280A and 280B of the element 28. In addition, the clamps 30A and 30B are installed in such a way that, when they move towards the locked position, they cross each other until they come into contact with the electrical conductor 100 which constitutes a limit stop of their locking. The clamps 30A and 30B are each provided with an end 38A and 38B which bears against a finger 504A or 504B of the covers 50A and 50B. The pairs of clamps 3 have the function of anchoring the detector 1 on the electrical conductor 100.
    [0009] The frame 2 includes two side walls 29. Each wall 29 is provided with two fixed pins 290A and 290B, projecting in a direction parallel to the axis X2 and opposite the pairs of clamps 3. Each wall 29 is also provided with two lights 292A and 292B, for receiving the projecting members 34A and 34B and a light 294 which receives the trigger 284.
    [0010] Each clamp 30A or 30B carries a circular finger 33A, respectively 33B, aligned on the axis X30A or X3OB and which extends on the same side as its protruding member 34A or 34B. Each finger 33A and 33B is rotatably mounted in a circular bore of corresponding shape, formed in the wall 29 adjacent. Thus, each clamp 30A or 30B is articulated on a wall 29, about its axis of rotation X30A or X30B, by engaging its finger 33A or 33B in the corresponding bore which is centered on this axis of rotation. The lights 292A and 292B are arcuate respectively centered on the X30A and X30B axes, while the light 294 is rectilinear and perpendicular to the plate 20.
    [0011] A spring 36A is stretched between the projecting member 34A and the fixed pin 290A on the side of the wall 29 opposite the pair of clamps 3. Similarly, a spring 36B is tensioned between the projecting member 34B and the fixed pin 290B. The springs are used for moving the clamps 30A and 30B to their open position or to their locked position. Figure 7 refers to the clamp 30A visible to the left of Figure 4 and schematically describes the operating principle for opening and for locking. The following explanation is applicable to all the clamps of the detector 1. Note X290A the longitudinal axis of the pin 290A which is parallel to the axes X2 and X30A. We note a line perpendicular to the axes X30A and X290A and secant with these axes. The line is parallel to the plate 20 of the frame 2. Note D1 the distance between the axes X290A and X30A measured parallel to the line 4, that is to say radially to the axes X30A and X290A. The protruding member 34A, introduced into the lumen 292A, is rotated about the axis of rotation X30A, the member 34A being integral with the clamp 30A. In Figure 7, the clamp 30A is schematically shown by a rod which defines a lever arm and extends between the member 34A and the axis of rotation X30A. Note D2 the distance between the member 34A and the axis of rotation X30A measured radially to the axis X30A, that is to say the length of the lever arm. In this representation, the distance D1 is substantially equal to the distance D2 but, in practice, and as shown in FIGS. 4 and 6, the distance D2 is equal to approximately 50% of the distance D1. It is expected that the distance D2 is less than or equal to half the distance D1. Indeed, a ratio D2 / D1 of less than or equal to 0.5 makes it possible to obtain high torques of movement of the clamp 30A, with slight variations in the spring 36A. The spring 36A exerts a force Fi on the member 34 towards the fixed pin 290A and a force F2 on the fixed pin 290A towards the member 34, these forces Fi and F2 being of equal intensity and opposite directions.
    [0012] When the member 34A is on the line 4, the couples associated with the forces Fi and F2 cancel each other out and the spring 36A produces no torque for the clamp 30A to move. This corresponds to a neutral or unstable equilibrium position. When the clamp 30A is in an open or semi-open position, the member 34A is above the line 4. The forces Fi and F2 cause an opening torque Cl on the clamp 30A, the pair Cl being in clockwise in Figure 7. The torque Cl pushes or maintains the clamp 30A in its fully open position which is therefore a stable position. When the conductor 100 bears on the portion 282 of the element 28, the trigger 284 bears against the portion 32A of the clamp 30A which is thus rotated about the axis X30A in the opposite direction of the needles of a shows in FIG. 7. The force of the trigger 284 opposes the torque Cl and pushes the member 34A below the line 4. Then, the forces Fi and F2 then cause a locking torque C2 on the clamp 30A, the pair C2 being in the counterclockwise direction in FIG. 7. The pair C2 pushes or holds the clamp 30A towards its fully locked position where the clamp 30A is in contact with the electrical conductor 100 which constitutes a locking end stop, regardless of its diameter. The locked position of the detector 1 is a stable position. This then allows the detector 1 to cling to electrical conductors of different diameters. The element 28 transmits the torque generated by the springs 36A and 36B to the legs 27A and 27B of the cover 27, as explained above. The springs 286 contribute to the opening and closing phases of the cover 27, in parallel with the springs 36A and 36B. The operation of the springs 286 is similar to that of the spring 36A described above. In particular, with reference to FIG. 5, three points can be identified on each portion 282: the shaft 280A, the base of the trigger 284 and the shaft 280B. These three points respectively correspond to the three points of FIG. 7, namely the protruding member 34A, the finger 33A and the pin 290A. The spring 286 is stretched between the shafts 280A and 280B, the shaft 280B is integral with the base of the trigger 284 and a rod which forms a lever arm is present between the shaft 280A and the base of the trigger 284. springs 286 thus produce a torque Cl or a pair C2 as a function of the position of these three points. In addition, the cowling system 5 comprises two springs 506 which have a similar operation to that described above for the spring 36A. The springs are inside the cowlings 51A and 51B and are anchored on the X51A and X51B axes.
    [0013] The torque produced by these springs 506 and 286 is consistent with the torque produced by the springs 36A and 36B, so that all the springs of the detector 1 cause either the opening or closing of the parts on which they act. Before installation, the detector 1 is in a closed configuration, as shown in FIG. 1. In particular, the covers 50A and 50B are closed, the surface 500A being in abutment against the surface 500B, as well as the magnetic core 22, the surface 220A being in abutment against the surface 220B, and the current sensor 26, the surface 260A being in abutment against the surface 260B. In addition, the clamps 30A and 30B are then in their locked configuration, the projecting members 34A and 34B being below the straight lines in the representation of FIG. 7, which induces locking torques 02, as explained above. . From this configuration, which precedes the installation, the rollover system 5 can be opened by pulling on the handles 502A and 502B to move them away from each other. The covers 50A and 50B slide on the side guide flanges 42 and the fingers 504A and 504B abut against the ends 38A and 38B of the clamps 30A and 30B. This rotates the clamps 30A and 30B around the X30A and X3OB axes and carries the projecting members 34A and 34B above the straight lines 4, which induces opening torques Cl, as explained above. The opening of the clamps 30A and 30B causes the total opening of the mechanism block 200, the member 28 transmitting the force of the pair of clamps 3 to the cover 27 and therefore to the magnetic core 22 and to the current sensor 26. The opening of the detector 1 is carried out in a single operation. The open configuration thus obtained can be considered as a stable configuration: this follows from the operating principle of the pairs of pincers 3. The detector 1 is then ready for installation. The detector 1 is raised at the height of the transmission line 102 with a pole which is anchored to the anchoring ring 44. The electrical conductor 100 bears against the portions 282 of the transmission element 28. 284. As described above, this induces locking torques 02 on the entire mechanism block 200. In particular, the clamps 30A and 30B close until they come into abutment against the conductor 100. This ensures the anchoring of the detector 1 to the conductor 100 of the line L10, as well as its putting into operation. The current sensor 26, which is then closed, can measure the current, which is then transmitted to the electronic device 6, which device is supplied by the whole of the core 22 and the coil 24. When the device 6 comprises a sensor of voltage, the potential of this sensor is taken by the anchoring clamps 30A and 30B. After having processed the output signals of the current sensor and the voltage sensor, the device 6 transmits a radio signal Si towards the concentrator 104, which receives the signals from the three detectors 1 mounted on the three lines 102. For the dismantling of the 1, using the pole anchored to the ring 44, the detector 1 is pulled down at an angle in the direction of the conductor 100 so that the conductor 100 exerts a force on the clamps 30A and 30B until the The springs of the block 200 produce opening torques Ci. This causes the opening of the detector 1 which can therefore be easily dismantled. The embodiments and alternatives contemplated above may be combined to generate new embodiments.
