Description

Technical Field

[0001] This invention relates to the grounding facility of the main welding machine for power distribution, and more specifically to the grounding facility of the main welding machine for power distribution, which involves wiring and protecting the grounding wire through the connection hole of the flange. Background Technology

[0002] This section provides background information related to the content of this application and is not necessarily prior art.

[0003] Generally, in order to reliably transmit the electricity generated by a power plant to a suitable receiving point, it needs to pass through a power distribution system, which includes the distribution of electricity via power lines. On the other hand, power poles are unsafe in the event of lightning strikes, and efforts are underway to install grounding devices to minimize the damage caused by lightning strikes.

[0004] As confirmed in registered patent No. 10-2236448, for utility poles constructed from multiple steel pipes connected in two or three sections, the flange structure formed by the protrusions at the pipe joints presents difficulties in using conventional straight-line grounding molding. For example, when using a traditional grounding mold in a "C" shape corresponding to the flange structure of a steel pipe pole, it is difficult for the grounding wire to penetrate the interior of the "C" structure. Furthermore, if the grounding molding of the flange section of the steel pipe pole is omitted, the grounding wire may be directly exposed and damaged. This type of grounding installation also violates electrical equipment safety technical standards.

[0005] To address this issue, Patent No. 10-2236448 describes a utility pole formed by connecting first and second flanges at the ends of different first and second pipes. The pole has a through hole formed along its length on the circumference of the first and second flanges, completely penetrating them. A notch is attached to the first and second flanges to secure them. One end of the pole is connected to an opening formed at the end of a grounding mold extending along the length of the pole, and the cross-end includes a connecting portion connected to the connecting part and the through hole. The grounding wire consists of the grounding mold, the connecting part, and the through hole wound sequentially and buried underground.

[0006] The aforementioned patent document stipulates that the signing part is inserted into the first and second holes of the first and second flanges, and a grounding wire is installed through the through hole. Considering the diameter of the first and second holes and the outer diameter of the grounding wire, the space is very narrow, making it difficult to install the grounding wire through the through hole. In other words, because the signing part is inserted into the first and second holes of the first and second flanges, the space for installing the grounding wire is reduced, and the first and second holes of the first and second flanges as a whole cannot be used as space for installing the grounding wire, resulting in poor construction.

[0007] In addition, the mating part has a structure that allows rainwater to seep in. This seeped rainwater cannot be removed and may damage the grounding wire and the mating part.

[0008] Furthermore, the aforementioned traditional techniques cannot detect issues such as twisting or deformation of the grounding wire, and therefore cannot predict the grounding wire's condition. Repair work can only be carried out after problems occur in the grounding system.

[0011] Patent Document 1: Korean Patent Registration No. 10-2236448 Summary of the Invention

[0012] The problem that the invention aims to solve

[0013] This invention aims to solve the aforementioned problems. When two or more pipes are connected by flanges to form a pole, the grounding wire bends outward along the flange. The connection hole of the flange is used to maintain straightness without any obstruction. In particular, no connection structure is inserted in the narrow connection hole of the flange. This provides a pole welding facility that can use the entire connection hole as a space for the grounding wire installation.

[0014] means for solving problems

[0015] The main welding point facility of the present invention refers to a grounding wire that is grounded to the ground by wiring along a pipe consisting of two circumferentially bolted and nut-connected pipes on a facing flange; the grounding wire is connected to the pole and inserted inside, and then wired through the connection hole of the flange. The grounding form is a forming machine body arranged vertically along the flange, which is open to the flange. An elastic pad is formed on the upper and lower sides of the flange insertion part, and the upper and lower connecting parts of the flange are formed together. The upper and lower connecting parts of the flange pipe and the flange at the upper and lower connecting parts of the flange form the flange connecting body. The connecting parts of the flange extend circumferentially on the left and right sides of the forming machine body and are fixed to the top of the flange. The forming machine body has fastening bolt wings on adjacent fastening holes on the left and right sides. The characteristic feature is that ribs formed on the flange and inserted into the wing portions include alignment portions that align with the mold body.

[0016] Invention Effects

[0017] According to the power distribution pole grounding facility of the present invention, even if the power pole is assembled into two or more pipes with outward flanges, the grounding wire can be inserted into the connection hole of the flange and the wiring can be carried out without large-angle bending, thereby preventing damage to the grounding wire. Moreover, the grounding mold is combined with the flange and the entire connection hole is opened, so the grounding wire can be easily installed even if the diameter difference between the grounding wire and the connection hole is not large.

[0018] In addition, due to the installation of the grounding wire, the flange insertion part of the grounding mold is reinforced by the signing hole part that cannot be signed, which has the effect of preventing the flange from warping or reducing its strength.

[0019] In addition, the grounding wire wiring mold is connected to the connection ports on the left and right sides through the wing section, so that the grounding wire is kept in the wiring state, thereby achieving the effect of stabilizing the grounding environment.

[0020] Furthermore, the grounding wire extends from the lower part of the flange to the ground as a protective part, which helps to prevent grounding wire contamination and collisions with stones and other objects on the side of the ground with more rain or pollutants.

[0021] At the same time, rainwater that seeps into the upper wiring conduit is drained into the drainage ditch from the upper side, which has the effect of preventing rainwater from damaging the grounding wire and causing malfunctions.

[0022] In addition, by utilizing the upper and lower segmented structure of the mold body, the deformation of the grounding wire can be detected above (on the upper part of the pole) and below (underground). This allows for the diagnosis and prediction of the grounding system, enabling maintenance before grounding system failures occur. This achieves stable power distribution system maintenance and significantly reduces costs. Attached Figure Description

[0038] In describing this invention, detailed descriptions of the functions or components of the invention will be omitted if it is believed that such descriptions might unnecessarily obscure the essence of the invention. Furthermore, the terms used below are defined for their functionality according to the invention and may vary depending on the intent or convention of the user or operator. Therefore, their definitions should be based on the entire contents of this listing.

[0039] like Figures 1 to 3 As shown, the power distribution pole welding facility of the present invention is applicable to the aforementioned power pole 10 consisting of two pipes (steel pipes, etc.) with flanges 11 and 12. The first and second pipes 11 and 12 respectively form flanges 11a and 12a at their ends, which are interconnected with the first and second flanges 11 and 12, and together with the first and second holes 11 and 2, form multiple interconnected first and second holes 11 and 2. 11c and 12c are approximately triangular in shape along the circumferential direction, and are assembled by connecting bolts 13 and nuts 14 on adjacent first and second connecting holes 11b and 12b.

[0040] The grounding facility of the present invention includes a grounding wire 20 laid along a pole 10, a grounding form 30 for fixing and protecting the grounding wire 20 to the pole 10, the grounding wire 20 being laid through first and second connecting holes 11b and 12b, and first and second flanges 11a and 12a being formed on first and second pipes 11 and 12, so that the grounding wire can be laid without deformation even when formed outwards, the grounding form 30, and the grounding wire of the protection state 20.

[0041] When the grounding wire 20 is laid underground along the pole 10, it passes through the upper part of the grounding mold 30, then through the first and second connecting holes 11a and 12a arranged vertically, and is buried underground after passing through the lower part of the grounding mold 30.

[0042] The grounding molding 30 includes a molding body 31, a flange insertion part 32, upper and lower wiring pipes 33 and 34, and wings 35 and 36.

[0043] The mold body 31 is a rectangular box shape arranged vertically along the first and second flanges 11a and 12a. It is the basic skeleton that constitutes the flange insertion part 32, etc., and can be made of various materials (insulators) such as metal and synthetic resin.

[0044] The mold body 31 includes a drainage hole 31a for draining infiltrated rainwater into the outer drainage pipe 33. The wind tunnel 31a consists of one or more components, passing through the interior of the upper wiring pipe 33 and the exterior of the casting body 31, and preferably slopes downward on the exterior of the casting body 31.

[0045] According to the present invention, in most of the first and second coupling holes 11b and 12b, one of the first and second coupling holes 11b and 12b does not engage with the bolt 13 and nut 14 because the grounding wire 20 is directly through it. Even if the above coupling hole is not engaged, the remaining first and second coupling holes 11b and 12b can also solve the coupling strength of the first and second flanges 11a and 12 through the above coupling hole, but it can also be solved by the feeling of weak coupling strength (flange).

[0046] The flange insertion part 32 has a groove structure that is open to three sides inside the mold body 31 that is wrapped around the upper and lower parts and the surrounding parts of the first and second flanges 11a and 12a. Therefore, by wrapping around the upper and lower parts of the first and second flanges 11a and 12a, they are joined together to prevent the first and second flanges 11a and 12a from opening, and are connected to the first and second holes 11b and 12 of the grounding wire 20 to protect the external grounding wire 20.

[0047] The material properties of the mold body 31 are relatively weak in elasticity, and the flange insertion part 32 may not be able to be firmly attached to the first and second flanges 11a and 12a. In order to solve this problem, elastic gaskets compressed by the first and second flanges 11a and 12a will be formed on the upper and lower sides of the flange insertion parts 11a and 12a respectively.

[0048] The mold body 31 is composed of upper and lower main parts through the flange insertion part 32 between the upper and lower sides, plus the upper and lower wiring pipes 33 and 34.

[0049] The cross-section formed by the upper and lower wiring pipes 33 and 34 is smaller than that of the mold body 31, and is the same as or larger than that of the first and second connecting holes 11b and 12b. A grounding wire 20 runs through the wiring inside.

[0050] Although the entire mold body 31 can be used as an insertion space for the grounding wire 20, interference will be caused when the grounding wire 20 is passed through in this case. The upper and lower wiring pipes 33 and 34 have the advantage of not causing interference and allowing the grounding wire 20 to pass through.

[0051] Since the grounding wire 20 passes through the upper and lower wiring pipes 33 and 34 and the first and second connecting holes 11b and 12b, the grounding mold 30 remains fixed, but may move in the direction of falling off the pole 10, thereby causing the grounding wire 20 to deform. In order to prevent this from happening, the wing parts 35 and 36 are included.

[0052] The wing portions 35 and 36 extend on the left and right sides of the mold body 31, overlap the first flanges 11a on the left and right sides of the mold body 31, and include holes connected to the first and second connecting holes 11b and 12b, so that the connecting bolts 13 can pass through.

[0053] In other words, the mold fuselage 31 is more firmly fixed to the prelude 10 through the wing parts 35 and 36.

[0054] In addition, when installing the grounding mold 30, it also includes alignment parts 35a and 36a, so that the upper and lower wiring pipes 33 and 34 are naturally connected to the first and second associating holes 11b and 112b.

[0055] The alignment parts 35a and 36a are the structure of the first rib 11c insertion groove. When the alignment parts 35a and 36a are inserted in conjunction with the first rib 11c, the upper and lower wiring pipes 33 and 34 match the first and second connecting holes 11b and 12b.

[0056] Wing sections 35 and 36 also have the function of preventing the grounding molding 30 from moving around.

[0057] In addition, the wing sections 35 and 36 can also be structures that cover the upper and lower parts of the first and second flanges 11a and 12a.

[0058] In addition, such as Figure 4 As shown, the second flange 12a is arranged at a certain height above the ground, and the grounding wire 20 is exposed at the lower part of the grounding mold 30. This part includes a protective part 40 to prevent contamination and damage to the grounding wire 20.

[0059] It is worth mentioning that, taking into account that the height from the ground to the second flange 12a varies depending on the construction site, the protection unit 40 is composed of a telescopic type or can be raised and lowered to connect to the grounding mold 30, as shown in the drawings.

[0060] The telescopic protective part 40 is a corrugated tube. Its upper end is fixed to the molding body 31 of the grounding molding 30. It is extended to the ground by the workers and placed on the ground to cover the grounding wire 20 for protection. Of course, the lower part can also be buried underground.

[0061] According to the present invention, the installation method of the main grounding facility for power distribution is as follows:

[0062] The first and second pipes 11 and 12 of pole 10 are constructed using flange connection (flange connection part). At this time, among most of the first and second connection holes 11b and 12b, there is one first and second connection hole 11b and 12b for the grounding wire 20 wiring that has no connection hole.

[0063] Simultaneously, a grounding mold 30 is installed on the flange joint of the pole 10: the alignment portions 35a and 36a of the grounding mold 30 are aligned with the first rib 11c, the grounding mold 30 is pushed in, the first rib 11c is inserted into the alignment portions 35a and 36a, and the first and second flanges 11a and 12a are inserted into the flange 31 in the space between the adjacent first ribs 11c of the wings 35 and 36 to form the molded body 31.

[0064] Grounding forming 30 can be done before or after assembling the first and second tubes 11 and 12 into connection ports. In subsequent work, the two connection ports for fixing the wing parts 35 and 36 have not yet been connected.

[0065] In this way, the gaps in the grounding wire 20 wiring and the first and second connecting holes 11b and 12b will arrange the interiors of the upper and lower wiring pipes 33 and 34 of the grounding mold 30 into a straight line.

[0066] A grounding wire 20 is laid along the ground on the upper side of the pole 10. The grounding wire 20 is inserted through the upper opening of the upper wiring pipe 32 of the grounding mold 30 and through the first and second connecting holes 11b and 12b of the first and second flanges 11a and 12a and the lower wiring pipe 34.

[0067] The grounding wire 20 is connected to the grounding rod through the lower wiring conduit 34. After being buried underground, the ground is leveled. This work is the same as before.

[0068] With the ground cleared, the flange joints of pipes 1 and 2 (11 and 12) are located above the ground. The protective part 40 is lowered to the ground and supported on the ground, so that the grounding wire 20 can be wired without being exposed to the outside and protected from contamination.

[0069] In addition, by arranging the mold body 31 in the upper and lower parts of the first and second flanges 11a and 12a, and taking the flange joint as a reference, the present invention can confirm the upper and lower deformation of the grounding wire 20.

[0070] like Figure 5 As shown, the casting body 31 is divided into an upper casting body 31-1 and a lower casting body 31-2, which are then movably connected by a rotating shaft 31-1, and a sensor 50 is installed to confirm the angle changes of the upper casting body 31-1 and the lower casting body 31-2.

[0071] Hinges 31-3 are suitable for torsion coil springs, etc., to keep the upper mold body 31-1 and the lower mold body 31-2 in their initial state (vertical straight type).

[0072] Sensors 50 are installed on the upper casting body 31-1 and the lower casting body 31-2 respectively, and can be used as angle measuring instruments to detect the angle between the upper casting body 31-1 and the lower casting body 31-2.

[0073] Based on the above configuration, as follows Figure 5 As shown, when deformation occurs on the upper side of the grounding wire 20, the upper molded body 31-1 will be activated, and the sensor 50 will detect the angle of the upper molded body 31-1 and send it to the controller.

[0074] The controller compares the reference angle (initial installation angle) of the upper molded body 31-1 with the current detection angle of the sensor 50, and outputs an alarm to the administrator's portable terminal and server when the two are different.

[0075] The same method can be used to confirm the deformation of the lower molded body 31-2.

[0076] The figure shows that the flange insertion part 32 is formed by the combination of the upper casting body 31-1 and the lower casting body 31-2. In this case, both the upper casting body 31-1 and the lower casting body 31-2 can be moved, so the deformation of the upper and lower sides of the grounding wire 20 can be confirmed.

[0077] Alternatively, in order to confirm the deformation of the upper or lower side of the grounding wire 20, only one of the upper casting 31-1 and the lower casting 31-2 is fixed on the first and second flanges 11a and 12a, including the flange insertion part 32, while the other casting 31-2 or 31-1 rotates.

[0078] In other words, if it is divided into an upper molded body 31-1 and a lower molded body 31-2, it includes confirming deformation on more than one side.
