    [0006]
    [0007] The object of the present invention lies in a device whose purpose is to provide a means for the protection of the blades of wind towers and of mobile or static structures that have metallic elements for capturing electrical charges on their surface, against discharges. direct atmospheric, as well as electromagnetic pulses that may affect them from atmospheric discharges between clouds, positive or negative, in their immediate surroundings and those that come from emissions from radiating towers or antennas, telecommunications, radars of any kind or other origin
    [0008]
    [0009] FIELD OF APPLICATION OF THE INVENTION
    [0010]
    [0011] The field of application of the present invention is part of the industry sector dedicated to the manufacture of devices, systems and devices for protecting metal structures against the collection of electric charges.
    [0012] BACKGROUND OF THE INVENTION
    [0013]
    [0014] As a reference to the current state of the art, it should be noted that, at least on the part of the applicant, the existence of any other electromagnetic compensating device, or any other application invention for the protection of blades of wind towers or other mobile or static structures with metallic elements for capturing electric charges or for any other similar application, which has the same or similar technical and structural characteristics as those presented here.
    [0015]
    [0016] EXPLANATION OF THE INVENTION
    [0017]
    [0018] The electromagnetic compensating device of variable radiofrequency for the protection of blades of wind towers or other mobile or static structures that the invention proposes, as noted above, has as its object the protection of the blades of wind towers and of mobile and static structures that have metallic elements for capturing electrical charges on its surface, against direct atmospheric discharges, as well as electromagnetic pulses that may affect it from atmospheric discharges between clouds, positive or negative in its immediate surroundings and those that come from emissions of towers or radiating antennas, of telecommunications, radars of any type or of another origin.
    [0019]
    [0020] The device object of the patent can be placed inside or outside the structure to be protected, depending on each case, although preferably it is arranged inside and, in any case, interconnected between the external pick-up elements of the structure to protect and the connection to the ground. In the case of protection of A blade of a wind tower, the device is placed inside the blade and is interconnected between the mobile or static pick-up elements (depending on whether the blade is moving or not) of the blade and its connection to the ground.
    [0021]
    [0022] The protection device is activated when a sufficient electrostatic charge accumulation appears, either of atmospheric origin due to the appearance of an electric field in its immediate environment or by electrification due to the constant movement of the electric charge sensing elements, such as for example, the constant movement of the blades of the wind tower or the movement of a crane or a mobile telescope, and electromagnetic pulses of variable radiofrequency, of atmospheric origin or coming from external sources such as radiating or telecommunications towers, radars, etc. .., first performing a high reactance effect (force against electromotive) to the passage of the high frequency current turning it into heat and giving way to the low current, to finally make a compensation of the existing loads between the connection to the elements external mobile or static sensors (e.g. shovels) and the socket of Earth. The compensation effect is activated at a certain potential difference value existing within the device and compensates all loads above this potential value, preventing upward tracers from forming on the mobile or static external pickup elements.
    [0023]
    [0024] The electromagnetic compensating device of variable radiofrequencies, object of the present invention, is the result of the knowledge of the frequency spectra existing in atmospheric phenomena and in the electromagnetic pulses generated therein and those derived from external sources, such as radiating towers, telecommunications, radars and signals to AM, FM, as well as research related to the analysis of resonant modes of Radio frequency variables in diverse structures.
    [0025]
    [0026] The design of the device object of the invention has also been based on studies on the results of the radiofrequency electromagnetic field obtained by simulation for distributions of the electric field E, magnetic field H and surface current density J at different moments of time comparable to each other in frequency spectra between 0.4 GHz and 1.9 GHz, where potential designs of resonant structures of electromagnetic fields that have a main resonant mode at a certain frequency in GHz and a quasi continuous of oblique modes in the rest of the frequency spectrum are concluded, achieving design results of the device object of the invention, which acts as an electromagnetic radiofrequency resonator that facilitates electrical discharges, mainly in the referred frequency spectrum (0.4 to 1.9 GHz). These electrical discharges take place by the absorption of the electromagnetic fields of variable radiofrequency and the recombination of the electric charges of different signs (mostly electrons and positive ions). This happens because of the participatory action of static electric and magnetic fields, as well as the electromagnetic field that resonates at various frequencies. Both actions facilitate the combination of charges as they are entertained (temporarily trapped) in nearby areas of confinement due to the effect of the electromagnetic radiofrequency field, where the compensation of electric charge is favored by the mobility action promoted by static fields.
    [0027]
    [0028] Therefore, the device of the invention has as its operating principle, on the one hand, to act with high reactance to the passage of high frequency currents transforming it into heat, allowing only low frequency currents to pass through and on the other hand, the compensation of Variable radiofrequency electromagnetic fields, acting as a constant sink, from a certain potential difference (of the order between 10-20 KV), of the variable frequency electric charges.
    [0029]
    [0030] These processes take place in the confinement of the device, which is a waterproof and fireproof box, but its permanent and quasi-continuous activity is felt in a wider environment, specifically in all the conductive structures connected in both terminals of the device, and are direct or by electrical continuity, since the compensatory processes of homogenization, conductivity between materials and thermalization favor the diffusion between conductive means in local imbalance environments.
    [0031]
    [0032] Based on these studies, and bearing in mind that the device has a limit on its electromagnetic compensation capacity, which basically depends on the transmission speed of the charges accumulated in the mobile or static collectors of the structure to be protected (for example, the blade of a wind tower) towards the device, as well as the value of the earth resistance to which the device is connected (it will always have to be less than 10 Ohms for a good transmission of electrical charges to the device) and the spectrum of frequencies of the transmitted current, with the installation of the device, a variable absorption of low intensity current to ground is achieved, preventing the mobile or static external collector systems of the structure to be protected in which it is incorporated, generate ascending tracers (derived from its own movement or possible variations of electric fields of atmospheric origin), ac oppression of electromagnetic pulses of variable frequencies radiated from the outside and possible saturations of electrostatic charges in said sensors.
    [0033] To do this, and specifically, the device comprises, essentially, two connecting conductive adapters, in charge of the connections of the device with the external sensors of the element to be protected, on the one hand, and with the earth connection, on the other; two elements of high reactance to the passage of the high frequency current and energy absorbers in the form of heat, one in charge of generating a force against electromotive to the passage of the initial high frequency current, lowering the frequency and absorbing part of the generated energy in heat, finally reaching the other element, once the current has passed through a central system formed by a dielectric insulator located between two conductive elements and that basically forms the frequency resonator, this other element of high reactance absorbs the residual energy and that only Let low frequency current flow.
    [0034]
    [0035] In addition, in the preferred embodiment, it also comprises two supports of insulating material, to fix the aforementioned elements inside a box, and which, in turn, prevent the central system of the dielectric insulator from touching the walls of said box. , a very important concept, since electric arcs can be formed between the conductive elements of said system in its normal operation and compensation process.
    [0036]
    [0037] On the other hand, said central system composed of the dielectric insulator and the mentioned two conductive elements arranged on both sides thereof, form the electromagnetic resonator and compensator itself.
    [0038]
    [0039] As for the box, preferably, it is a box of insulating material, waterproof and air-tight, with mechanical and fire-retardant protection, essential so that electric charges only enter through the connecting conductor adapters, which are located externally in opposite sides of the box, and there is no entry of electrified air or water, which could vary the operating conditions of the resonator or cause a loss of insulation and endurance of the heat conditions that will be generated internally, which at least It will have to hold up to 200 ° C.
    [0040]
    [0041] The device also includes, in the case, a series of pressure aeration valves from the inside out and sealed at the entrance of humidity and air, responsible for removing the internal overpressure from the box, so that there is always the same pressure inside and outside the box, as well as to extract moisture from inside the box that may be present and prevent moisture from entering the box.
    [0042]
    [0043] Preferably, the box comprises four pressure aeration valves, although said number may vary and will depend on the speed and quantity of air to be evacuated, so that there is no excessive overpressure inside the box that can break it. Normally there will be a minimum of two valves and a maximum of four valves.
    [0044]
    [0045] Finally, it should be mentioned that the described elements of the device may have various geometric shapes, which will depend on the needs and protection design of the structures to which it is intended.
    [0046]
    [0047] In any case, the only premise is that, in order for the electromagnetic compensating device of variable radiofrequency to work correctly, it must be taken into account that the conductive elements that are located on both sides of the dielectric insulator must have a specific separation, depending on of the conductivity of the material used and the degree of insulation of said dielectric element.
