Abstract
Description
Technical Field
[0001] This invention relates to a power distribution grounding structure that allows for horizontal or vertical extension of the grounding length of the grounding wire within a protective enclosure when the grounding wire is installed underground (e.g., underground). Background Technology
[0002] Recent rapid industrialization, informatization, and urbanization have led to massive energy consumption in densely populated areas. Consequently, accidents caused by the surge in electricity consumption are on the rise, making a stable power supply to industrial facilities crucial. Furthermore, concerted efforts are underway to mitigate power outages caused by natural disasters.
[0003] In general, in order to reliably transmit the electricity generated by the power plant to the general receiving price, transmission lines or distribution lines will be used, which will be installed using transmission towers or distribution lines.
[0004] To prevent electric shock accidents caused by leakage current from power lines, grounding wires will be installed on the poles of these transmission or distribution towers.
[0005] It is recommended to insert the grounding wire into the power distribution wire for installation. However, if a grounding wire is to be installed after the power distribution wire is installed, it should be installed with the grounding wire exposed outside the power distribution wire. Since the grounding wire is exposed, a protective cover should be provided to prevent damage to the grounding wire. Part of the protective cover should be buried in the ground (e.g., underground) at a depth of more than 0.75 meters away from the power distribution wire.
[0006] However, since the grounding wires of the power distribution line grounding devices were previously buried underground, the grounding length of the buried grounding wires was always very short, resulting in poor grounding wire functionality.
[0007] When this traditional grounding wire is buried in the ground for a long time, it is necessary to purchase additional devices to extend the length of the grounding wire, which has the disadvantage of increased cost for extending the grounding wire.
[0008] Therefore, a device is needed to directly extend the grounding length of the grounding wire from the protective sleeve in the absence of a device for extending the grounding wire length.
[0009] Prior art related to this invention is Korean Patent Registration No. 10-1131172 (March 28, 2012, publication date), which describes a "grounding device for power distribution lines". Summary of the Invention
[0010] The problem that the invention aims to solve
[0011] In various embodiments of the present invention, in order to horizontally extend the length of the grounding wire placed inside the protective shell in the ground, the lengths of a plurality of first grounding wires are rotated horizontally in the grounding shell, and in order to further vertically extend the length of the grounding wire, the lengths of a plurality of second grounding wires are rotated vertically from the plurality of first grounding wires, extending in the grounding shell in the length direction of the grounding wire, thus providing a structure for a sliding grounding wire.
[0012] Methods for solving problems
[0013] According to various embodiments of the present invention, the grounding structure of the power distribution line is arranged on the side of the power distribution wire, and a protective shell is provided on its inner side to guide and protect the grounding wire from ground to ground; a grounding shell is rotatably attached to the outer side of the protective shell, formed in the length direction, connected to the grounding wire, and has openings on both sides, which are placed face-to-face or perpendicular to the protective shell when rotated, and when placed perpendicularly, form a grounding shell in the horizontal direction of the grounding length of the grounding wire; a plurality of first grounding wires are rotatably attached to both sides of the grounding shell, which are led out from the opening of the grounding shell and folded or led out and unfolded according to the rotation, and when led out and unfolded, horizontally extend the grounding length of the grounding wire; and a plurality of second branches are rotatably attached to both sides of the first branch; including that these plurality of second grounding wires can be rotated into a plurality of fixing slots formed on both sides of the plurality of first grounding wires when not in use, and folded and fixed, or rotated away from the plurality of fixing slots when in use, so that the grounding length of the grounding wire is further vertically extended and unfolded perpendicular to the lower side direction of the grounding wire.
[0014] According to various embodiments of the present invention, one end of the grounding housing may form a first grounding rotating part, which is rotatably coupled to the rotating part protruding from the side of the protective housing. The end of the grounding housing may slide to be inserted or removed from the opening formed on the front of the grounding housing in the length direction. The sliding movement extends the grounding length of the grounding wire along the length direction of the grounding housing by sliding grounding.
[0015] According to various embodiments of the present invention, the first grounding rotating part may include a grounding connection part electrically connected to the grounding wire through the grounding through hole formed with the protective shell rotating part.
[0016] According to various embodiments of the present invention, one end of the plurality of first grounding pairs forms a rotatable second grounding rotating pair on a rotating protrusion formed inside the plurality of mounting slots, and the striking end of the plurality of first grounding pairs can form a rotatable third grounding rotating pair on a rotating hole formed by the plurality of second grounding pairs.
[0017] Invention Effects
[0018] According to various embodiments of the present invention, a rotatable grounding shell is arranged on the side of the protective shell. When the grounding shell is rotated from the protective shell and orthogonally arranged, it rotates to form a plurality of first grounding wires with horizontally extended grounding lengths. The grounding length of the grounding wires is further extended based on the grounding length of the first grounding wires. By forming a sliding grounding part, the plurality of first and second grounding parts and the sliding grounding part can conveniently further extend the grounding length of the grounding wires. This allows leakage current and overvoltage of the grounding wires to flow rapidly into the ground, thereby further improving the function of the grounding wires.
[0019] Furthermore, the aforementioned multiple first and second grounding wires and sliding grounding wires can be directly extended and additionally extended without the need to purchase extension devices for individual grounding wires, thereby reducing the cost of extending grounding wires.

[0041] According to various embodiments of the present invention, the grounding structure (100) of the power distribution line rotates at one end of the protective shell (20) to place a grounding shell (110) forming the grounding length of the grounding wire (11). Rotating on the grounding shell (110), a plurality of first grounding portions (120) that horizontally extend the grounding length of the grounding wire (11) are placed. In addition, a second grounding length that extends the grounding length is extended on the first grounding portions (120) of the grounding wire (120). The grounding length of the grounding wire (11) on the grounding shell (110) can be one or more combinations of various devices that can form a sliding grounding wire (112) that further extends the grounding length of the grounding wire (11) in the length direction of the grounding wire (110) by sliding movement.

Figure 8 This is a side view of the rotation and sliding states (112) of a plurality of first and second grounding portions (120) in the configuration of the grounding structure (100) of the power distribution line according to various embodiments of the present invention.
[0043] Reference Figures 1 to 8 The grounding structure (100) of the power distribution line may include a protective shell (20), a grounding shell (110), and multiple first and second grounding parts (120, 130). For example, the interior of the protective shell (20) may be formed as a hollow tube or as a non-conductive synthetic resin to prevent leakage current and overvoltage from flowing to the outside of the power distribution line. That is, the protective shell (20) may be arranged on the side of the power distribution line (10). For example, the inner side of the protective shell (20) may be protected by a grounding wire (11) that is grounded (C1) (e.g., underground).
[0044] These grounding wires (11) can be grounded into the ground (e.g., underground) to prevent electric shock accidents caused by leakage current and overvoltage in the power distribution lines.
[0045] These protective shells (20) can be 2.76 meters or longer, so that the part exposed on the ground is more than 2 meters long and the part underground is more than 0.76 meters long. For example, the length of the aforementioned protective shell (20) is limited to meet the installation requirements of the grounding wire (11) of the public utility in the distribution of electricity by Korea Electric Power Corporation, which requires that the part exposed on the ground be protected by more than 2 meters of synthetic resin and that the part underground (C1) require more than 0.76 meters of grounding wire (11).
[0046] The grounding housing (110) is rotatably attached to the outside of the protective housing (20). For example, the grounding housing (110) may be formed along the length and electrically connected to the grounding wire (11).
[0047] Openings (110a) can be formed on both sides of the aforementioned grounding housing (110) so that the plurality of first groundings (120) described later can be led out or led out according to rotation.
[0048] When the grounding housing (110) is rotated, it can be arranged face-to-face or orthogonal to the protective housing (20). When arranged orthogonally, it can form the horizontal direction of the grounding length of the grounding wire (11).
[0049] At one end of the grounding housing (110), a first grounding rotating pair (111) may be formed, which is rotatably coupled to a rotating pair (21) protruding from the side of the protective housing (20).
[0050] These first grounding rotating parts (111) can be composed of grounding connection parts electrically connected to the grounding wire (11) through the grounding through hole (22) formed in the rotating part of the protective shell (20). That is, when the grounding connection part is electrically connected to the grounding wire (11), it can transmit the leakage current and overvoltage of the grounding wire (111) to the grounding shell (110). In this way, the grounding shell can flow to the ground through multiple first and second grounding parts (120, 130) and sliding grounding parts (112), the latter describing the leakage current and overvoltage of the grounding wire (111).
[0051] At the striking end of the grounding housing (110), a sliding grounding device (112) can be placed at the opening formed on the front of the grounding housing (110) and slidably moved in the longitudinal direction to be introduced or removed.
[0052] For example, the sliding ground (112) can slide from the opening (110b) formed on the front of the ground housing (110) in the length direction, thereby further extending the grounding length of the grounding wire (11) when it is led out to the length direction of the ground housing (110).
[0053] The plurality of first grounding points (120) are rotatably coupled to both sides of the grounding point housing (110). For example, the plurality of first grounding branches (120) can be folded or extracted and unfolded from the openings (110a) formed on both sides of the grounding housing (110) by rotation. If the plurality of first grounding wires (120) are extracted and unfolded, the grounding length of the grounding wires (11) can be extended horizontally.
[0054] On both sides of the aforementioned plurality of first connecting branches (120), a plurality of stabilizing grooves (120a) can be formed to rotatably connect the aforementioned plurality of second connecting branches (130). That is, the aforementioned plurality of mounting grooves (120a) can hold the aforementioned plurality of second groundings when not rotated.
[0055] One end of the plurality of first grounding portions (120) can form a second grounding rotating portion (121) that can be rotatably connected on the rotating protrusion (113) formed inside the plurality of mounting slots (120a).
[0056] The striking ends of the plurality of first receiving branches (120) can form a third grounding rotating part (122) that can be rotatably connected on the rotating hole (131) formed by the plurality of second receiving branches (130).
[0057] The aforementioned plurality of second terminals (130) are rotatably coupled to both sides of the aforementioned plurality of first terminals (120). For example, when not in use, the aforementioned plurality of second grounding wires (130) can rotate on the aforementioned plurality of mounting slots (120a) and be folded and placed on them, while when in use, the aforementioned plurality of second grounding wires (130) can rotate away from the aforementioned plurality of mounting slots (120a), thereby further extending the grounding length of the grounding wire (11) in the vertical direction.
[0058] In other words, the aforementioned multiple second groundings can be rotated by the third grounding rotating part (122) formed at the striking end of the aforementioned multiple first grounding parts (120) and unfolded in a direction perpendicular to the lower side of the aforementioned grounding housing (110).
[0059] In this state, if the grounding length of the grounding wire (11) placed inside the protective shell (20) is extended, the grounding shell (110) placed on the side of the protective shell (20) can be rotated vertically and horizontally so that it intersects directly with the protective shell (20).
[0060] At this time, the grounding housing (110) can be rotated by the first grounding rotating part (111) and placed horizontally.
[0061] In this state, a plurality of rotatable first grounding points (120) can be horizontally rotated and attached to the openings (110a) on both sides of the grounding housing (110), while being extracted and unfolded from the openings (110a).
[0062] The aforementioned plurality of first grounding wires (120) can be extracted and unfolded from the aforementioned opening (110a), while the grounding length of the aforementioned grounding wires (11) is extended in the horizontal direction.
[0063] In this state, if the grounding length of the grounding wire (11) is further extended, the multiple second grounding wires (130) can be rotated and unfolded in the multiple stabilizing grooves (120a) formed on both sides of the multiple first grounding wires (120).
[0064] For example, the aforementioned plurality of second supports (130) can rotate and unfold vertically away from the aforementioned plurality of mounting slots (120a).
[0065] At this time, the grounding length of the above-mentioned grounding wire (11) can be vertically extended by the above-mentioned multiple second grounding wires (130).
[0066] Furthermore, if the grounding length of the grounding wire (11) is further extended in the length direction of the grounding housing (110), the sliding grounding part (112) can be extracted by sliding from the opening (110b) formed on the front of the grounding housing (110) in the length direction.
[0067] For example, the sliding joint (112) can be extracted from the opening (110b) on the front of the grounding housing (110) while sliding in the longitudinal direction.
[0068] At this time, the sliding grounding part (112) can further extend the grounding length of the grounding wire (11) to the length direction of the grounding shell (110).
[0069] Similarly, by rotating on the grounding housing (110), multiple first grounding wires (120) are formed, extending the grounding length of multiple first grounding wires (11) horizontally, and multiple second grounding wires (130) are formed on the multiple second grounding wires (130), extending the grounding length of the grounding wires (11) vertically. By extending the grounding length of the grounding wires (11) on the grounding housing (110), the grounding wires (112) slide along the sliding (110) of the grounding wires to the multiple sliding directions. The first and second grounding wires (120, 130) and the sliding grounding wire (112) can conveniently extend and lengthen the grounding length of the grounding wires (11), thereby allowing the leakage current and overvoltage of the grounding wires (11) to flow rapidly to the ground, thus further improving the function of the grounding wires (11). No grounding wire extension device is required, and the cost of extending the grounding wires (11) can also be saved.
[0070] The power distribution line grounding structures described in the various embodiments of the present invention are not limited to the foregoing embodiments and drawings. Various substitutions, modifications and alterations can be made within the technical scope of the present invention, which will be obvious to those skilled in the art.
