Abstract
Description
Technology Field
[0001] The present invention relates to a lightning protection system for a transmission line tower, and more specifically, to a lightning protection system for a transmission line tower with an improved structure to protect electrical facilities from lightning strikes by preventing birds, etc., from building nests on a lightning rod installed at a predetermined height and provided at the top of the transmission line tower. Background Technology
[0003] Generally, lightning is a phenomenon in which enormous electrical energy, generated by static electricity generated by the flow of active air currents, is discharged to the surface of the earth.
[0004] In other words, to prevent damage caused by lightning strikes, which possess tremendous destructive power, lightning rods must be installed when constructing various facilities to rapidly discharge the current into the ground upon impact.
[0005] These lightning rods were installed at great cost on utility poles, transmission towers, broadcasting and telecommunications transmission and reception towers, power generation or substation equipment, hazardous materials and petroleum storage tanks, structures or buildings installed in soil with high grounding resistance (sand, crushed stone, bedrock), and military bases (radar bases) for the purpose of discharging currents, such as lightning strikes, into the ground.
[0006] To achieve the above purpose, a conventional lightning rod comprises a lightning rod (10) having a male screw portion (11) formed at one end, a fixing member (20) having a female screw portion (21) into which the male screw portion of the lightning rod is screwed, an insulator (30) into which the fixing member is fitted, and a connecting member (40) that is coupled to the insulator and connected to a connecting pipe (50), as illustrated in detail in FIG. 6.
[0007] Meanwhile, in the case where a plurality of lightning rods (10) are installed so that the fixed member (20) of the conventional lightning rod in the city is connected to the insulator (30) in a way that prevents rotation, and is installed at a certain height on the upper part of a transmission line tower as an example, birds frequently build nests on it, so it fails to properly perform its function as a lightning rod, and this degradation of functionality results in a problem in that it cannot protect multiple electrical facilities installed on the transmission line tower when actual lightning strikes occur.
[0008] To elaborate, typically, a single lightning rod is installed on top of a transmission tower to protect electrical facilities from lightning strikes; however, due to the fixed structure of the lightning rod, if a new house is built on that single rod, the protective function against lightning strikes is not achieved, potentially leading to massive damage.
[0009] Therefore, since transmission tower managers frequently inspect the towers visually and forcibly remove bird nests built on lightning rods from high altitudes using equipment such as drones or helicopters, or have workers climb the towers directly to remove them, this results in additional problems, including safety accidents and economic losses caused by the use of equipment.

[0014] As a means of solving the problem of solving the aforementioned conventional problems, the lightning protection system for a transmission line tower according to the present invention comprises a lightning rod installed on the upper part of a transmission line tower (P / T) to protect electrical facilities from lightning, wherein the lightning rod is equipped with a grounding wire (111) that is grounded to the ground (G), and comprises a pole member (100) installed to have a predetermined height on the upper part of the transmission line tower (P / T), a rotating member (200) rotatably installed on the upper part of the pole member (100), a fixed member (300) inserted through the rotating member (200) and having its lower part fixedly coupled to the pole member (100), and a lightning rod member (400) provided on the rotating member (200) and the fixed member (300) respectively and directly contacting the lightning, wherein the power for the rotating member (200) to rotate is provided by the wind speed in the atmosphere. The lightning rod member (400) is characterized by including a main lightning rod (410) installed to have a vertical length so as to be detachable from the fixed member (300), and a plurality of sub-lightning rods (420) installed radially to have a length so as to be detachable from the fixed member (300) and each having a diagonal length on the outer surface of the rotating member (200).
[0015] Additionally, the rotating member (200) includes a rotating body (210) having a rotating space (211) formed inside and a through hole (H1) formed on the outer surface for the fixed member (300) and the pole member (100) to be coupled together, and a wind direction sphere (220) formed radially on the outer surface of the rotating body (210) and molded into a hemisphere with a groove to provide power for the rotating body (210) to rotate by wind, wherein a plurality of fastening holes (H2) are formed on the upper corner portion of the rotating body (210) so that the sub-lightning rod (420) can be fastened at an angle, and a rotating sphere (230) can be movably seated on the upper surface of the rotating body (210) so as not to interfere with the rotating body (210) in which the fixed member (300) inserted through the rotating space (211) centered on the through hole (H1) is rotating. It is preferable that the first rotational groove (217) be formed.
[0016] Additionally, an insertion groove (213) into which the pole member (100) that moves up and down is inserted is further formed on the lower surface of the rotating body (210), and a magnet (215) for attaching and detaching the pole member (100) by magnetic force is provided on the inner wall of the insertion groove (213) to control the rotation of the rotating body (210).

[0019] In addition, by controlling the rotation of the rotating member through a lifting mechanism, which is distinct from conventional methods, multiple sub-lightning rods are maintained in a fixed state, thereby allowing for the expectation of further enhancing the function of preventing damage to electrical facilities caused by lightning strikes.

[0025] Furthermore, in describing the present invention, if it is determined that a detailed description of related known functions or configurations may unnecessarily obscure the essence of the invention, such detailed description is abbreviated or omitted.
[0027] Hereinafter, a lightning protection system for a transmission line tower according to the present invention (hereinafter briefly referred to as the "lightning protection structure") will be described in detail with reference to the attached drawings.
[0028] Before the explanation, the lightning rod member (400) in the present invention described below includes a main lightning rod (410) installed vertically on a fixed body (310) and a plurality of sub-lightning rods (420) mounted in a diagonal shape on a rotating body (210). Since it has the same structure as a conventional 'Y-type lightning rod' that directly contacts high-voltage lightning and grounds to the ground (G) through the grounding wire (111) of the pole member (100), a detailed explanation will be omitted.
[0029] First, as illustrated in FIGS. 1 to 5, the lightning rod structure (1) according to the present invention comprises a pole member (100), a rotating member (200), a fixed member (300), and a lightning rod member (400).
[0030] To explain in more detail, the pole member (100) is equipped with other components described later, and is installed at a predetermined height on the upper part of a transmission line tower (P / T), and includes a pole support plate (110), a pole (120), and a lifting means (130) in a configuration to allow high-voltage lightning strikes to be grounded to the ground (G).
[0031] For example, the pole support plate (110) is formed into the shape of a plate as shown in the illustration, and a grounding wire (111) connected to the ground (G) is detachably mounted on the outer surface.
[0032] The pole support plate (110) has an insertion groove (113) formed therein for inserting the lower part of a pole (120) having a column shape, and a plurality of ribs are formed radially on the outer surface of the insertion groove (113) so as to improve the fixing force of the pole (120) inserted and installed in the insertion groove (113).
[0033] Additionally, as shown in the illustration, the pole (120) is formed into a column shape having a length in the vertical direction, and the lower part is inserted into the inlet groove (113) and fixedly installed on the pole support plate (110) by applying pressure such as a bolt.
[0034] A rotating member (200), a fixed member (300), and a lightning rod member (400), which will be described later, can be mounted on the upper part of the pole (120). In particular, the rotating member (200) is installed so as to be rotatable with respect to the upper part of the pole (120), and the fixed member (300) is installed so as to be screw-coupled with the pole (120).
[0035] As shown in the illustration, the pole (120) is formed as a single pipe so that its length cannot be adjusted, or satisfies a double pipe structure in which multiple pipes having different outer diameters can enter and exit as needed, thereby allowing the length of the pole (120) to be adjusted. In the present invention, a structure in which the length cannot be adjusted is described as an example.
[0036] The pole (120) can be formed using a material having conductive properties so that the voltage of the lightning strike can be smoothly applied to the grounding wire (111).
[0037] In addition, a ring-shaped groove (121) is formed on the upper part of the pole (120) to be inserted so as to contact the bearing (B) provided in the rotating body (210) described later.
[0038] Additionally, the lifting means (130) is configured to be detachably inserted into the rotating member (200) described later and to physically control the rotation of the rotating member (200), and includes a lifting platform (131), a lever (133), and a fixing pin (135).
[0039] The lifting platform (131) is not for the purpose of height adjustment as described above, but moves up and down according to the rotation direction of the lever (133), and through the lifting, the upper part of the lifting platform (131) can move in and out of the insertion groove (213) formed on the lower surface of the rotating body (210).
[0040] To this end, the lifting platform (131) is formed in the shape of a pipe that is inserted to surround the outer surface of the pole (120) as described above, and is provided so that it can be freely lifted by the lever (133).
[0041] At this time, it is preferable that the lower surface of the lifting platform (131) always remain in contact with the lever (133) so that it is guided to the outer surface of the pole (120) and rises in accordance with the rotational direction of the lever (133).
[0042] As described above, the lever (133) is rotatably installed on the lower outer surface of the pole (120) and is formed to be biased in one direction to raise and lower the lifting platform (131) provided on the outer surface of the pole (120).
[0043] Thus, when one side of the biasedly protruding lever (133) is raised upward, that is, toward the rotating member (200), the lifting platform (131) is inserted and inserted into the insertion groove (213), and when the corresponding side is directed downward, that is, toward the ground, the lifting platform (131) can be lowered.
[0044] The fixing pin (135) is configured to maintain the state in which the lifting platform (131) is inserted into the rotating body (210) by supporting the lifting platform (131) so that it does not descend due to the load of the lifting platform (131) when the lifting platform (131) is raised by the rotation of the lever (133) described above.
[0045] To this end, the fixing pin (135) is inserted into a plurality of fixing holes (H3) when the fixing holes (H3) formed in the lever (133), the platform (131), and the pole (120) respectively align with each other, thereby helping to fix the platform (131) in the raised state as well as the rotated lever (133).
[0046] And, the rotating member (200) is rotatably installed on the upper part of the aforementioned pole (120) to block birds from approaching and prevent the construction of a birdhouse, and includes a rotating body (210), a wind direction member (220), and a rotating member (230) in a configuration to block damage to electrical facilities caused by lightning strikes together with a main lightning rod (410) mounted on a fixed member (300).
[0047] For example, as illustrated, the rotating body (210) has a rotating space (211) formed inside, and through holes (H1) are formed facing each other at the top and bottom so as to be rotatably installed on the upper part of the pole (120).
[0048] At this time, a bearing (B) is formed at the end of the through hole (H1) formed in the lower part of the rotating body (210) so as to reduce frictional resistance with the pole (120) during rotation, and it is preferable that the bearing (B) be installed to be inserted into a groove (121) formed on the outer surface of the pole (120) so that the rotating body (210) can rotate in a fixed position without detaching from the pole (120).
[0049] A plurality of fastening holes (H2) are formed in the upper corner portion of the rotating body (210) to allow a plurality of sub-lightning rods (420) to be detachably fastened radially around the main lightning rod (410), and the fastening holes (H2) are formed in a diagonal shape so that the sub-lightning rods (420) can be installed in a diagonal shape.
[0050] On the upper surface of the rotating body (210), a first rotational groove (217) is formed in the shape of a ring centered on a through hole (H1) formed on the upper surface, and the first rotational groove (217) is provided so that a rotating ball (230) can move in the longitudinal direction.
[0051] In addition, the fixed body (310) passes through the through hole (H1) formed on the upper surface of the rotating body (210) and is screw-coupled with the upper end of the pole (120) placed in the rotating space (211).
[0052] At this time, it is preferable that a second rotation groove (311) is formed on the lower surface of the fixed body (310) in contact with the rotating ball (230) in the same way as the first rotation groove (217), and a detailed explanation thereof will be provided below.
[0053] The rotating body (210) has an insertion groove (213) formed on its lower surface centered around a through hole (H1) for the upper part of the lifting platform (131) to enter and exit, thereby allowing the rotation of the rotating body (210) to be controlled.
[0054] To this end, the inner wall of the insertion groove (213) is provided with a magnet (215) that is attached and detached by magnetic force to the outer surface of the lifting platform (131), which is formed with conductive properties such as metal, thereby controlling the rotation of the rotating body (210) so that it does not detach from the insertion groove (213) due to the load of the lifting platform (131) along with the support of the lever (133) described above.
[0055] Additionally, as described above, the wind direction spheres (220) are formed radially on the outer surface of the rotating body (210) around the through hole (H1) and are molded in the shape of a hemisphere having grooves so that power can be generated for the rotating body (210) to rotate by being influenced by wind in the atmosphere.
[0056] Additionally, as described above, the rotating ball (230) is formed to have an overall hard ball shape using a metal having conductive properties as well as a synthetic resin having non-conductive properties, and its lower part is inserted into a first rotation groove (217) formed on the upper surface of the rotating body (210), and its upper part is inserted into a second rotation groove (311) formed on the lower surface of the fixed body (310) to prevent contact between the rotating body (210) and the fixed body (310).
[0057] Additionally, the rotating body (210) in the present invention satisfies a structure in which a bearing (B) is inserted into a groove (121) formed on the upper part of a pole (120) as described above, and a plurality of wind direction holes (220) are affected by the wind speed in the atmosphere, thereby allowing the rotating body (210) to rotate.
[0058] Here, in order to ensure smooth rotation between the rotating body (210) and the pole (120), the groove (121) is designed to have a larger surface area than the bearing (B) to prevent friction with the inserted bearing (B). This gap allows for movement that can come into contact with the lower surface of the fixed body (310) inserted through the upper surface when the rotating body (210) rotates, and since this contact is a physical collision, it causes a problem of reduced durability between them.
[0059] Thus, in order to overcome the above-mentioned problem, a plurality of rotating balls (230) are provided between the upper surface of the rotating body (210) and the lower surface of the fixed body (310), and the rotating balls (230) are installed to be movable in the first rotating groove (217) and the second rotating groove (311) so that the frictional force with the rotating balls (230) can be reduced even when the rotating body (210) rotates, thereby preventing friction with the fixed body (310) even when the rotating body (210) rotates at high speed due to the wind speed.
[0060] And, the above-mentioned fixing member (300) includes a fixing body (310) having a second rotation groove (311) formed therein, configured to allow the main lightning rod (410) to be mounted vertically on the pole (120).
[0061] For example, as illustrated, the fixed body (310) has a fastening hole (H2) formed on its upper portion for detachably screwing into the main lightning rod (410), and its lower portion has a structure in which a protruding column is formed to screw into the fastening hole (H2) formed on the upper portion of the pole (120) by penetrating the through hole (H1) formed on the upper portion of the rotating body (210).
[0062] As described above, a second rotation groove (311) is formed on the lower surface of the fixed body (310), in which a rotation ball (230) is provided in a vertical direction opposite to the first rotation groove (217). Since this is explained in detail in the above description, additional explanation will be taken from the above description.
[0063] The fixed body (310) is formed using a material with conductive properties so that high-voltage lightning can be applied to the pole (120) through the fixed body (310) and then grounded to the ground (G) through the grounding wire (111).
[0064] As described above, the lightning rod structure (1) according to the present invention is different from the conventional one in that it uses an eco-friendly energy source to rotate the rotating member (200) provided on the upper part of the pole (120), thereby blocking birds from approaching and preventing the construction of a bird nest, so that when lightning strikes, the function of the lightning rod member (400) is maintained, and the effect of protecting the electrical facilities installed on the transmission line tower (P / T) is expected.
[0065] In addition, by controlling the rotation of the rotating member (200) through the lifting means (130) in a manner distinct from conventional methods, a plurality of sub-lightning rods (420) are maintained in a fixed state, thereby allowing for the expectation of further enhancing the effect of preventing damage to electrical facilities caused by lightning strikes.
[0067] As described above, the present invention has been explained by specific details such as specific components, limited embodiments, and drawings; however, this is provided merely to aid in a more comprehensive understanding of the invention, and the invention is not limited to the above embodiments. A person skilled in the art can make various modifications and variations from this description.
