Description

Technical Field

[0001] This invention relates to the field of lightning suppression technology, and in particular to a passive active lightning suppression device. Background Technology

[0002] Previous active lightning suppression devices based on ionized air have been proposed. During thundercloud development, when the spatial electric field changes, a probe column attracts the thundercloud charge, generating a high-intensity electric field between the upper and lower electrodes. This ionizes the air between the electrodes, producing a large number of positive and negative ions. These ions diffuse to the outside of the plasma generator and rapidly drift and conduct towards the areas of strong charge accumulation at the bottom of the thundercloud and the areas of strong opposite charge accumulation induced on the ground, respectively, thus interrupting the lightning's path and reducing the spatial potential, thereby blocking the lightning's development. However, improving the air ionization efficiency remains a subject for further research. Summary of the Invention

[0003] The purpose of this invention is to provide a device that improves air ionization efficiency, thereby more effectively achieving passive active lightning suppression.

[0005] Preferably, the upper and lower electrodes have cylindrical walls with equal radii.

[0006] More preferably, on the unfolded plane of each cylinder wall structure, the concave portion forms a semi-circular arc, and the protruding portion forms an inverted U-shaped vertical protrusion sandwiched between adjacent concave portions and extending continuously longitudinally from the concave portion. The inverted U-shaped vertical protrusion is composed of a square portion extending longitudinally from the concave portion and a semi-circular end continuously formed from the square portion.

[0007] More preferably, the upper and lower electrodes, used as the ionization nozzle ends, have the same structure, and the center of the semi-circular end of the outward protrusion on one electrode coincides with the center of the semi-circular arc of the inward concave portion on the other electrode. Furthermore, on the unfolded plane of each cylinder wall structure, the arc diameter of the inward concave portion is 5.5 times the width of the outward protrusion.

[0008] Further preferably, the upper and lower electrodes, used as the ionization nozzle ends, have the same structure, and the minimum distance between these nozzle ends on the unfolded plane of each cylinder wall structure is equal. Even further, the minimum distance is 26 mm. Still further, the longitudinal length of the square portion of the inverted U-shaped vertical protrusion is 12 mm.

[0009] In addition, the focusing structure may include: multiple sets of sensing needles for sensing the spatial electric field; multiple guide rods that respectively gather and connect each set of sensing needles and collect and conduct the charge sensed by each set of sensing needles to the equipotential body; and the equipotential body that uniformly applies the charge collected and conducted by the multiple guide rods to the ion generating structure.

[0017] The passive nature of the lightning suppression device described in this invention is reflected in its ability to ionize air molecules to neutralize environmental charges when excited by the atmospheric or thundercloud electric field. The active nature of the lightning suppression device is reflected in its ability to actively alter the thundercloud electric field potential through the plasma generated by ionization, thereby disrupting the formation conditions of the lightning leader. Based on this principle, the passive active lightning suppression device provided by this invention possesses both a focusing structure and an ion-generating structure.

[0018] The focusing structure is used to sense the spatial electric field and attract the induced charge to the ion generating structure. In the field of lightning suppression technology, the spatial electric field should be generally understood as the electric potential formed in space under natural conditions, either from the atmospheric electric field or induced by thunderclouds.

[0019] It should be understood that any structure capable of inducing a spatial electric field and attracting induced charges to act on the ion-generating structure, including its composition, materials, component combinations, and the position and connection relationships between components, should be considered within the scope of the attracting structure. However, this invention provides a preferred embodiment of the attracting structure.

[0020] In this preferred embodiment, the focusing structure includes: multiple sets of sensing needles for sensing the spatial electric field; multiple guide rods that respectively gather and connect each set of sensing needles and collect and conduct the charge sensed by each set of sensing needles to the equipotential body; and the equipotential body that uniformly applies the charge collected and conducted by the multiple guide rods to the ion generating structure.

[0021] According to the principles of lightning suppression, the sensing needle, the current guide rod, and the equipotential body are arranged from top to bottom, and according to the principles of lightning suppression, the sensing needle, the current guide rod, and the equipotential body are all made of metal.

[0022] The ion generating structure includes upper and lower electrodes, the upper electrode being configured to receive the charge exerted by the equipotential body, and the lower electrode being configured to be grounded.

[0023] The upper electrode and the lower electrode both form a cylindrical wall structure, and each cylindrical wall has an outer protrusion and an inner concave portion that are alternately formed along the cylindrical wall in the circumferential direction at the cylindrical opening end. The upper and lower electrodes are arranged relative to each other with a certain space between them, so that the outer protrusion of one electrode is opposite to the inner concave portion of the other electrode.

[0024] Here, the ends of the cylinder are arranged opposite each other in a coaxial manner with a certain space between them.

[0025] This creates an ionization gap of ionized air between the ionization ends of the cylinder walls of the upper and lower electrodes.

[0026] The outer periphery of the cylindrical wall structure only needs to be a gently curved surface, but as a preferred example, both the upper and lower electrodes have cylindrical walls. Furthermore, as a further preferred example, the cylindrical radii of the upper and lower electrodes are equal. This allows the protruding portion of one electrode to correspond longitudinally with the concave portion of the other electrode.

[0027] However, this is not the only possibility. There are also cases where the cylinder wall radii of the upper and lower electrodes are not equal. This results in the protruding part of one electrode and the concave part of the other electrode being longitudinally offset by a certain angle. In this case, the difference between the cylinder wall radii of the upper and lower electrodes should not be too large, for example, not greater than the distance between the apex of the corresponding protruding part and the concave part.

[0028] In a preferred embodiment, the protruding portions and concave portions of the upper and lower electrodes correspond one-to-one, thereby forming a meandering ionization gap between the ionization ends of the cylinder walls of the upper and lower electrodes. However, in a modified embodiment, the protruding portions and concave portions of the upper and lower electrodes do not correspond one-to-one; for example, two protruding portions correspond to two concave portions.

[0029] As one embodiment, both the protruding portion and the concave portion are arc-shaped, and the curvature of the protruding portion is greater than that of the concave portion. As a further defining example, the protruding portion and the concave portion alternate continuously, thereby forming a corrugated ionization gap between the ionization ends of the cylinder wall of the upper and lower electrodes.

[0030] However, in a preferred embodiment, on the unfolded plane of each cylinder wall structure, the concave portion forms a semi-circular arc, and the protruding portion forms an inverted U-shaped vertical protrusion sandwiched between adjacent concave portions and extending continuously longitudinally from the concave portions. The inverted U-shaped vertical protrusion consists of a square portion extending longitudinally from the concave portion and a semi-circular end continuously formed from the square portion.

[0031] As a further preferred example, the upper and lower electrodes, used as the ionization nozzle ends, have the same structure, and the center of the semicircular end of the outward protrusion on one electrode coincides with the center of the semicircular arc of the inward concave portion on the other electrode. Even more preferably, on the unfolded plane of each cylinder wall structure, the arc diameter of the inward concave portion is 5.5 times the width of the outward protrusion.

[0032] As another further preferred example, the upper and lower electrodes, used as the ionization nozzle ends, have the same structure, and the minimum distance between these nozzle ends on the unfolded plane of each cylinder wall structure is equal. More preferably, the minimum distance is 26 mm. Even more preferably, the longitudinal length of the square portion of the inverted U-shaped vertical protrusion is 12 mm.

[0033] Therefore, a "camel-shaped" air ionization gap is formed between the ionization ends of the cylinder walls of the upper and lower electrodes, which can achieve a more efficient air ionization.

[0034] Here, the upper electrode can be configured to be electrically connected to or coupled to the equipotential body as part of the equipotential body. This lightning suppression device can also be equipped with a base, and the lower electrode can be configured to be electrically connected to or coupled to the base as part of the base. Additionally, support columns for spaced support and positioning of the upper and lower electrodes can be configured, with the upper and lower ends of the support columns respectively fixed to the lower end face of the equipotential body and the upper end face of the base.

[0035] It should be understood here that although the present invention uses a cylindrical wall structure to form the upper and lower electrodes, the scheme of connecting the bottom cylindrical structure with the equipotential body or base should also be regarded as a conductive connection or coupling into a whole concept.

[0036] Based on lightning suppression principles, the upper and lower electrodes and the base are made of metal. The supporting columns are made of insulating material with sufficient strength.

[0037] In addition, a support frame can be provided to support the base. This support frame can be a steel tower, metal bracket, lifting rod, etc., connected to the base with bolts. The base is fixed to the support frame using screw holes at the lower end. The support frame also undertakes the task of guiding the conduction of induced charges on the ground.

[0038] Figure 1 A more specific implementation example is shown in the reference. Figure 1 The passive active lightning suppression device 100 is described as a more specific embodiment of the present invention.

[0039] The number of sensing pins in each group of sensing pins 111 is not limited; for example, 7 pins are used in this example, but other methods are also possible. Figure 2 The number of needles shown is 12 or other quantities. The tip angle of the sensing needle is set to 22 degrees in this example, but it is not limited to this.

[0040] Each group of sensing needles 111 is arranged in an inverted umbrella shape. For example, with one sensing needle as the center, other sensing needles are evenly distributed around the sensing needle and tilted outward. Preferably, the other sensing needles tilt outward at the same angle, and more preferably, the tilt angle is 30 to 45 degrees.

[0041] A sensing needle seat 111a is provided between the sensing needle 111 and the guide rod 112. Both the sensing needle 111 and the sensing needle seat 111a are made of metal. In this embodiment, the sensing needle 111 is made of stainless steel and the sensing needle seat 111a is made of aluminum alloy.

[0042] The sensing needle holder 111a can be connected to the sensing needle 111 and the guide rod 112 by threads respectively. As an example of the threaded connection, multiple threaded holes for inserting the lower end of the sensing needle 111 can be provided at the upper end of the sensing needle holder 111a, and a threaded hole for the upper end of the guide rod 112 can be provided at the lower end of the sensing needle holder 111a.

[0043] As a variation, the sensing needle holder can be omitted, and the groups of sensing needles can be conveniently connected directly to the guide rod. This invention does not limit this.

[0044] In the implementation structure including the sensing needle holder, the inverted umbrella-shaped arrangement of the plurality of sensing needles 111 is preferably such that the sensing needle located at the center coincides with the axis of the guide rod 112.

[0045] The other ends of the multiple guide rods 112 are fixed to the surface of the equipotential body 113 by bolts and are distributed in an umbrella shape. In this example, five guide rods are used, one of which is erected at the top center of the equipotential body 113, and the other four are evenly arranged around the central guide rod perpendicular to the equipotential body 113.

[0046] In another embodiment, such as Figure 3 As shown, the guide rod 112 adopts a double-rod structure, with the upper rod 112a inserted and fixed to the lower rod 112b. The connection method between the upper rod 112a and the lower rod 112b is not fixed; for example, they can be directly connected by threads or welded at the joint. Alternatively, the lower rod 112b can be directly fitted with a sleeve, and the upper rod 112a can be inserted into and fixed to the lower rod 112b. Regardless of the variation, it must ensure smooth charge conduction between the upper rod 112a and the lower rod 112b. Furthermore, a telescopic and locking structure can be formed between the upper rod 112a and the lower rod 112b. The guide rod 112 (including the upper rod 112a and the lower rod 112b) is made of metal; in this embodiment, aluminum alloy is used.

[0047] In this example, the equipotential body 113 adopts a hemispherical structure. The hemispherical end is connected to each of the guide rods 112, concentrating the attracted charges from the guide rods. The lower end of the equipotential body 113 is a circular plane, aligned with and electrically connected to the upper electrode 114. This invention is not limited to this; the equipotential body 113 can also be coupled integrally with the upper electrode 114. The lower electrode 115, as an example, is shown to be integrally coupled with the base 116.

[0048] The upper end face of the base 116 and the lower end face of the equipotential body 113 (which is the same as the upper end face of the base 116, so the figure is omitted) are provided with fitting grooves. The support column 119 is used to support the upper and lower electrodes. Its upper and lower ends have fitting flanges, which are respectively fitted into the fitting grooves of the lower end of the equipotential body 113 and the upper end face of the base 116.

[0049] Multiple through-holes are uniformly formed at corresponding positions on the lower flange of the support column 119 and the upper surface of the base 116. The support column 119 and the base 116 are fixed together by inserting and tightening multiple screws accordingly. Similarly, multiple through-holes are uniformly formed at corresponding positions on the upper flange of the support column 119 and the lower surface of the equipotential body 113. The support column 119 and the equipotential body 113 are fixed together by inserting and tightening multiple screws accordingly. As a variation, the upper electrode 114 can also be a bottomed cylindrical shape. In this case, multiple through-holes are formed at corresponding positions along with the bottom of the upper electrode 114. The support column 119, the upper electrode 114, and the equipotential body 113 are fixed together by inserting and tightening multiple screws accordingly.

[0050] The fixed connection method between the equipotential body 113 and the base 116 and the support column 119 is only an example here. As long as the upper and lower electrodes can be isolated and positioned in a certain space, any variable method can be adopted.

[0051] In addition, in this example, insulating fins 119a are formed longitudinally on the support column 119 to improve insulation performance.

[0052] The upper electrode 114 and the lower electrode 115 are used to form an ion generating structure. The upper electrode 114 is connected to the equipotential body 113 to receive the charge exerted by the equipotential body 113. The lower electrode 115 is grounded by being coupled to the base 116.

[0053] Thus, the upper electrode 114 and the lower electrode 115 are relatively isolated by a certain space through the configuration of the supporting column 119, thereby forming an ionization space between the upper and lower electrode cylinder walls.

[0054] In the specific example above, the upper electrode 114 and the lower electrode 115 are made of 5083 aluminum alloy, the support column 119 is made of nylon or glass fiber reinforced nylon, and the threaded parts used to fit the support column 119 can be made of metal or insulating material.

[0055] By designing the interlocking grooves, the metal components can be made into a hollow structure as much as possible, thus reducing weight to some extent. According to the practical application of this invention, when the diameter of the upper electrode is 150 mm, the weight of this lightning suppression device is no more than 9 kg; when the diameter of the upper electrode is 100 mm, the weight is no more than 1.5 kg; and when the diameter of the upper electrode is 200 mm, the weight is no more than 25 kg.

[0056] like Figures 1-3As shown, both the upper electrode 114 and the lower electrode 115 form a cylindrical wall structure, and each cylindrical wall, used as the ionization port end, alternately forms multiple external protrusions 117 protruding along the cylindrical wall and multiple internal concave portions 118 recessed along the cylindrical wall in the circumferential direction. The external protrusions 117 of one electrode correspond one-to-one with the internal concave portions 118 of the other electrode and extend to the internal concave portions 118 of the other electrode, thereby forming a configuration in which the external protrusions 117 and internal concave portions 118 are opposite to each other, as shown. Figures 1-3 As shown, a meandering ionization gap is formed between the ionization ends of the cylinder wall of the upper electrode 114 and the lower electrode 115.

[0057] Specifically, Figure 4 This is an unfolded plan view of the cylindrical wall structure of the upper and lower electrodes 114 and 115. On this unfolded plane, the concave portion 118 forms a semi-circular arc, and the protruding portion 117 forms an inverted U-shaped vertical protrusion sandwiched between adjacent concave portions and extending continuously longitudinally from the concave portions. The inverted U-shaped vertical protrusion consists of a square portion 117a extending longitudinally from the concave portion and a semi-circular end 117b continuously formed from the square portion.

[0058] In this example, the upper and lower electrodes 114 and 115, used as the ionization nozzle ends, form the same structure, such as... Figure 3 As shown, the center O of the semicircular end of the protruding part on one electrode coincides with the center O' of the semicircular arc of the concave part on the other electrode.

[0059] This creates a "camel-shaped" air ionization gap between the ionization ends of the cylinder walls of the upper and lower electrodes.

[0060] The camel-shaped design adopted in this invention makes the air ionization efficiency higher, and the working process is in a corona state. Compared with other forms of ionization and plasma release, it achieves maximum effectiveness and can also avoid the instantaneous electromagnetic pulse radiation and crackling noise caused by arc discharge.

[0061] In addition, the discharge is achieved by placing the electrode on the outer wall, allowing for smooth 360° ventilation and unobstructed release of the plasma. This fully utilizes the airflow to drive ion diffusion, improving the drawback of low ion release rate leading to decreased activity. Furthermore, it avoids the problem of difficulty in cleaning once contaminants enter, as was the case with isolation barriers in the past.

[0062] The following provides an ionization intensity test of a camel-shaped ionization gap according to the present invention. The test uses the aforementioned reference... Figures 1-3 The example describes the structure and materials, and the relevant dimensions and material selection are as follows.

[0063] upper and lower electrode cylinder wall radii: 75mm

[0064] Concave radius: 31.9mm

[0065] Length of square section: 12mm

[0066] Radius of the semicircular end: 5.8mm

[0067] Gap distance: 26mm (tolerance ±0.1mm)

[0068] Induction needle: Stainless steel

[0069] Induction needle holder, guide rod, equipotential body, and upper and lower electrodes: 5083 aluminum alloy

[0070] Support column: Glass fiber reinforced nylon

[0071] Figure 5 This is a simulation diagram of the electric field gathering capability based on the test. The electric field distribution inside and outside is uniform and strong. The highest electric field strength appears at the peak of 1995.7 kV / m, and the highest electric field strength in the top and gap is 87 kV / m.

[0072] The passive active lightning suppression device provided by this invention integrates the equipotential body, plasma generator, and base into one unit, resulting in a compact structure, small size, and light weight, while forming a large high-voltage electric field volume. Within the effective area, the ionization zone is larger and stronger, adapting to various harsh environments. The concentrated spatial electric field generates a self-sustaining discharge in the ion generator; ionization causes the molecular structure to produce positive and negative electrons that escape outward at 2.64 m / s (survival time 6 minutes), neutralizing the positive and negative charges between the thundercloud and the ground, disrupting the lightning leader formation mechanism, and achieving large-area lightning protection.

[0073] This invention's passive active lightning suppression device, under the influence of the atmospheric electric field and thundercloud induction in the natural environment, accumulates the energy of the spatial electric field. When the induced charge reaches a certain concentration, the local electric field ionizes the surrounding air molecules, generating plasma. Negative ions are captured by oxygen molecules to generate negative oxygen ions, while positive ions drift upwards, neutralizing the charge between the cloud and the ground, reducing the potential between them, and disrupting the conditions for the formation of lightning leaders, effectively blocking lightning strikes. This passive active lightning suppression device can effectively prevent direct lightning strikes within a protection angle of not less than 86°, achieving zero direct lightning strikes within a large area of ​​14 times the protection radius from the installation height.

[0074] After hundreds of tests, the passive active lightning suppression device of this invention has been verified to have no strict requirements for grounding and can reliably operate with a grounding resistance of 500 to 1000 ohms, far exceeding any grounding specification. Verified in a lightning rod testing laboratory, even under the worst-case conditions simulating a thundercloud plate with hundreds of thousands of volts breaking down the air medium, the ground current of the passive active lightning suppression device of this invention is very small, and the residual voltage on the ground is very low. Specifically, the measurement method involves connecting a 1-ohm resistor in series with the grounding wire; the voltage across this 1-ohm resistor is only a few volts to tens of volts, meaning that over 99% of high-voltage lightning strikes are blocked.

[0075] This invention ensures the device operates in real-time, 24 / 7. Even slight changes in the atmospheric electric field can trigger the passive active lightning suppression device to rapidly generate plasma, intervening in the spatial electric field and operating in a corona state. When thunderclouds change rapidly, it operates in a glow discharge state. For lightning protection of targets, the most important aspects are avoiding direct lightning strikes and close-range (including those near lightning arrester towers) lightning strikes. Applying this passive active lightning suppression device can both prevent direct lightning strikes and reduce the damage to both strong and weak electrical systems caused by strong transient electromagnetic pulses induced by close-range lightning strikes.
