[0003] Grounding is the process of connecting electrical terminals to the earth to protect operators from electric shock accidents and prevent insulation breakdown of equipment when excessive abnormal voltage, such as lightning surges or switching surges, enters power circuits or electronic devices due to accidents in power facilities, insulation failures, or other factors. It is also used to improve functionality by eliminating noise in information and communication facilities to achieve high-quality information transmission. In other words, it refers to a means of electrically connecting a metal or conductive object to the earth to equalize its potential with that of the earth or to minimize the potential difference.

[0054] Recycled carbon fibers replacing grounding rods

[0055] A recycled carbon planar body replacing a grounding rod according to one embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG. 1 is a simplified illustration of a recycled carbon planar body replacing a grounding rod according to one embodiment of the present invention, FIG. 2 is a cross-sectional view illustrating the AA cross section of FIG. 1, FIG. 3 is a cross-sectional view illustrating the BB cross section of FIG. 1, FIG. 4 is a separate illustration of each layer to explain the layer composition of the recycled carbon planar body replacing a grounding rod according to one embodiment of the present invention, and FIG. 5 is a cross-sectional view illustrating the CC cross section of FIG. 1.

[0056] According to one embodiment, a recycled carbon planar body replacing a grounding rod according to one embodiment of the present invention comprises an insulating substrate (110); a carbon felt layer (130) formed on the insulating substrate (110); and a stainless steel mesh (150) formed on the carbon felt layer (130).

[0057] The above insulating material (110) is a surface that contacts the utility pole and serves to prevent current flowing through the carbon planar body along the grounding wire of the utility pole from flowing into the utility pole.

[0058] The insulating material (110) may have a thickness of 0.5 mm to 4 mm, specifically 1 mm to 4 mm, and more specifically 2 mm to 4 mm. Within this range, it may have flexibility without allowing current to flow into the electric pole.

[0059] The above insulating material (110) has a surface resistance of 10 3 It can be greater than Ω / cm. Insulation performance can be satisfied within the above range.

[0060] The above insulating material (110) may include one or more of a rubber insulating material, a PP (polypropylene) insulating material, a nonwoven fabric insulating material, and a PP (polypropylene) mesh insulating material.

[0061] The carbon felt layer (130) may be formed on the insulating substrate (110). The carbon felt layer (130) may be formed by impregnating RCF (Recycled Carbon Fiber) into a thermoplastic resin.

[0062] The above thermoplastic resin may include one or more of MAPP, PC, and epoxy resins.

[0063] The carbon felt layer (100) above can be formed by polymerizing a composition for forming a carbon felt layer comprising 15 to 30 weight% of a monomer for forming a thermoplastic resin; and 70 to 85 weight% of RCF (Recycled Carbon Fiber). Low resistance can be achieved within the above range, while there is no problem with the water content.

[0064] The above monomer for forming a thermoplastic resin may include one or more of a monomer and an intermediate for forming MAPP (Maleic anhydride grafted polypropylene).

[0065] The monomer for forming the thermoplastic resin may include one or more of a monomer and an intermediate for forming polycarbonate (PC).

[0066] The above monomer for forming a thermoplastic resin may include one or more of a monomer and an intermediate for forming an epoxy resin.

[0067] The carbon felt layer (130) may have a thickness of 0.5 mm to 5 mm, specifically 1 mm to 5 mm, and more specifically 3 mm to 5 mm. Within this range, the current of the utility pole grounding wire can be sufficiently grounded.

[0068] The stainless steel mesh (150) can be formed on the carbon felt layer (130). The present invention has the advantage of significantly improving the conductivity of the carbon planar body while preventing carbon fiber leakage from the carbon felt layer (130) and simplifying the manufacturing process by applying the stainless steel mesh (150).

[0069] The stainless steel mesh (150) can be formed with a mesh structure of 12 mesh to 35 mesh, specifically 15 mesh to 30 mesh, and more specifically 17 mesh to 27 mesh. Within this range, the leakage of carbon fibers from the carbon felt layer (130) can be prevented, sufficient conductivity can be secured, and there is no problem with flexibility.

[0070] The stainless steel mesh (150) has a wrapping portion (151, 152, 153, 154) formed in one or more directions of one side, the other side, the upper side, and the lower side, which is larger than the area corresponding to the insulating material (110) and the carbon felt layer (130), and the wrapping portion can be formed by folding to wrap the lower carbon felt layer (130) and the insulating material (110).

[0071] The stainless steel mesh (150) may have a thickness of 0.05 mm to 1 mm, specifically 0.08 mm to 0.5 mm, more specifically 0.08 mm to 0.25 mm. In this range, the balance of flexibility and conductivity of the carbon planar body is excellent.

[0072] Referring to FIG. 4, the stainless steel mesh (150) has a wrapping portion formed therein, which protrudes more than the insulating substrate (110) and carbon felt layer (130) area (wrapping portion), and this can be formed by folding downwards based on FIG. 4 and wrapping the carbon felt layer (150) and insulating substrate (110) as shown in FIG. 5.

[0073] The present invention has the advantage of being able to simply fix and maintain the insulating substrate (110), carbon felt layer (130), and stainless steel mesh (150) by folding the wrapping portion, without the need for a separate bonding process or heat pressing process, by configuring the wrapping portion of the stainless steel mesh (150).

[0074] The wrapping portion may include one or more of a first-side wrapping portion (151), a second-side wrapping portion (152), an upper-side wrapping portion (153), and a lower-side wrapping portion (154).

[0075] The extension length of the wrapping portion may be 0.5 cm to 10 cm, specifically 1 cm to 8 cm, and more specifically 3 cm to 6 cm. Within this range, the fixing force between the insulating material and the carbon felt layer is sufficient, while minimizing the risk of current flowing into the utility pole through the stainless steel mesh (150).

[0076] Referring to FIGS. 3 to 5, the grounding rod replacement recycled carbon planar body may further include a conductivity improvement part (170) formed in a bar shape on one or more of the upper corners of the stainless steel mesh (150), the other corner, the upper corner, and the lower corner.

[0077] In FIG. 4, only the conductivity improvement parts (170) on one side and the other side are shown, but they can be applied differently depending on the application environment, purpose, etc.

[0078] The conductivity improvement part (170) is additionally provided on the carbon felt layer (130) and stainless steel mesh (150) to further improve conductivity, and can also serve to completely flow current flowing from the grounding wire of the utility pole into the carbon planar body through the structure described later.

[0079] The conductivity improvement member may include SUS, and the conductivity improvement member may have a width of 5 mm to 60 mm, specifically 10 mm to 50 mm, more specifically 10 mm to 40 mm.

[0080] Referring to FIGS. 3 to 5, the grounding rod replacement recycled carbon planar body may further include a blocking member (190) formed in a bar shape at one or more of the one-sided corner, the other-sided corner, the upper corner, and the lower corner of the lower part of the insulating material (110).

[0081] The above blocking member (190) prevents current from flowing into the electric pole of the carbon planar body, and in particular, serves to block current from flowing into the electric pole of the wrapping portions (151, 152, 153, 154) of the stainless steel mesh (150).

[0082] In FIG. 4, only the blocking members (190) on one side and the other side are shown, but they can be applied differently depending on the application environment, purpose, etc.

[0083] The above blocking member (190) may be formed larger than the corners on one side, the other side, the upper side, or the lower side corresponding to the insulating material (110), as shown in FIG. 4.

[0084] The above blocking member (190) may be formed of insulating plastic, and for example, the blocking member may include PE (polyethylene).

[0085] Referring to FIG. 6, the blocking member (190) may include two or more slit-shaped grooves (195) formed in a direction parallel to the corner of the insulating member (110) being placed. The grooves (195) can be used as grooves for joining when a carbon planar body is installed to surround a utility pole, and a structure for joining using the grooves (195) can be applied using a member that is easy for a person skilled in the art to use.

[0086] Referring to FIG. 5, the blocking member (190) can be formed by contacting the insulating material (110) and the wrapping portions (151, 152, 153, 154). By forming such a structure, the current of the stainless steel mesh (150) can be completely blocked from flowing into the utility pole.

[0087] Although not illustrated, when an upper wrapping portion (153) and / or a lower wrapping portion (154) are formed, a blocking member (190) may be formed at a corresponding position, or a film of the same material as the insulating material (110) may be bonded to serve as a blocking member.

[0088] The above blocking member (190) may have a width of 30 mm to 100 mm, specifically 40 mm to 90 mm, more specifically 40 mm to 80 mm. Within this range, it is easy to block the current of the stainless steel mesh (150) while simultaneously attaching the carbon planar body to the utility pole.

[0089] Referring to FIGS. 4 and 5, the grounding rod replacement recycled carbon planar body may further include a plurality of bolts (210) and nuts (220) that sequentially penetrate a blocking member (190), wrapping portions (151, 152, 153, 154), an insulating material (110), a carbon felt layer (130), a stainless steel mesh (150), and a conductivity improvement portion (170).

[0090] Referring to FIGS. 6 and 7, the conductivity improvement section (170) may have a grounding connection section (173) to which the grounding wire (300) of the utility pole is connected. By connecting the grounding wire (300) to the grounding connection section (173) of the conductivity improvement section (170) which has high conductivity, all current can be smoothly grounded through the carbon planar body.

[0091] Referring to FIG. 6, the grounding coupling portion (173) can be formed in the conductivity improvement portion (170) via a bending portion (171) that is formed by bending in the upward direction and can be spaced apart from the stainless steel mesh (150).

[0093] Hereinafter, the structure and operation of the present invention will be explained in more detail through preferred embodiments of the present invention. However, these are presented as preferred examples of the present invention and should not be interpreted in any way as limiting the present invention.

[0094] Details not listed here can be sufficiently technically inferred by a person skilled in this field, so their explanation will be omitted.
