Description

Recycled Carbon Planar Element Replacing Ground Rod The present invention relates to a recycled carbon planar body that replaces a grounding rod. 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. Until now, grounding rods, deep-driving grounding rods, and circular grounding electrodes have been commonly used for grounding utility poles; however, these methods have the disadvantage of excessive construction time and costs due to additional excavation and complex construction procedures, and damage to underground utilities caused by various factors is also a problem. In addition, existing grounding methods require the installation of two or more copper rods due to the small grounding area, and there were problems such as deformation, peeling, and corrosion of the grounding rods. Meanwhile, carbon-zero policies aimed at minimizing carbon dioxide and encouraging recycling have recently become a global issue, and recycling is one of the important measures for reducing carbon. Accordingly, a grounding method is required that offers a large contact area, a simple construction process, and minimizes corrosion; additionally, a carbon planar body is required that can utilize recycled carbon fibers to impart conductivity to the carbon planar body. However, carbon planar bodies using existing carbon-derived materials had problems such as a shortened lifespan due to carbon loss over time, the need to perform a separate heat-pressure process during manufacturing, or insufficient conductivity. Accordingly, there is a need for a carbon planar body that prevents carbon loss, ensures sufficient conductivity, has a simple manufacturing process, and offers high insulation reliability with respect to utility poles.
