Description

Earthing structure of distribution line Technical Field The present invention relates to a distribution line grounding structure that allows a ground length of a ground line to be horizontally or vertically extended in a protective case when the ground line is installed in the ground (e.g., underground). Background Recently, society has undergone abrupt industrialization, informatization and urbanization, and consumes a lot of energy in dense areas. Therefore, recently, accidents caused by the rapid increase of the power consumption are increasing, and it is very important to stably supply power to industrial facilities. In addition, efforts are being made to reduce the interruption of power supply caused by natural disasters. In general, in order to stably deliver electric power generated by a power station to a generally accepted price, power transmission lines or distribution lines are used, and these power transmission lines or distribution lines are installed using power transmission towers or distribution lines. In order to prevent an electric shock accident from occurring due to leakage current of distribution lines, a grounding wire is provided on the utility pole of the power transmission tower or the distribution tower, which is grounded to the ground. It is recommended that the ground wire is inserted into the distribution wire for internal installation, but if the ground wire is installed after the distribution wire is installed, the ground wire is exposed to the outside of the distribution wire for installation, because the ground wire is exposed to the outside, and in order to prevent the ground wire from being damaged, a protective cover is covered, and a part of the protective cover is buried in the ground (e.g., underground) at a position more than 0.75 m deep from the distribution wire by 1 m. However, since the ground wire of the conventional distribution line grounding device is buried in the ground (e.g., underground), the ground length of the buried ground wire is always short, and thus there is a problem in that the function of the ground wire is lowered. Such conventional ground wires have a disadvantage in that they require additional purchase of a device for extending the length of the ground wire when they are formed in the ground for a long time for landfill, and the ground wire is increased in cost. Therefore, there is a need for a device that extends the ground length of a ground wire directly from a protective sleeve without having a device that extends the ground wire length. The prior art related to the present invention is registered in korean patent publication No. 10-1131172 (2012.03.28, publication date), and the description of the "distribution line grounding device" has been made in the prior art. Disclosure of Invention Problems to be solved by the invention In various embodiments of the present invention, in order to horizontally extend the length of the ground wire placed inside the protective case in the ground, the length of the plurality of first ground wires is rotated in the ground housing in the horizontal direction, and in order to further vertically extend the length of the ground wire, the length of the plurality of second ground wires is rotated in the vertical direction from the plurality of first ground wires, and in order to extend in the ground housing in the length direction of the ground wire, a structure of sliding ground wires is provided. Means for solving the problems According to various embodiments of the present invention, a ground structure of a distribution line is disposed at a side of a distribution wire, a protective case whose inner side guides a ground wire from ground to ground and protects the ground wire, a protective case rotatably coupled to an outer side of the protective case, formed in a length direction, connected to the ground wire, formed with openings at both sides, placed face to face or vertically with the protective case when rotated, formed with a ground shell of the ground wire in a horizontal direction of a ground length when placed vertically, a plurality of first ground wires rotatably coupled to both sides of the ground case, drawn out from the openings of the ground case according to rotation and folded or drawn out to be unfolded, and a plurality of second ground wires rotatably coupled to both sides of the first ground parts, including, the plurality of second ground wires may be rotated to a plurality of fixing grooves formed at both sides of the plurality of first ground wires and folded and fixed next, or rotated to be separated from the plurality of fixing grooves when used, so that the ground wire is further extended in a vertical direction of the ground wire. According to various embodiments of the present invention, the ground housing may have a first ground rotating portion formed at one end thereof, and rotatably coupled to the rotating portion protruding from the side surface of the protective housing,
