일반적으로 산업화, 정보화 및 도시화되는 현대사회는 밀집된 지역에서 많은 에너지를 소비하는 특징을 가지며, 이러한 에너지 중 가장 사용이 편리하고 수송이 간단하며 공해가 없는 깨끗한 에너지로서 사용되는 전력의 안정적인 공급은 산업 전반에 걸쳐 중요한 요인이 되는 실정이다.In general, industrialized, informatized and urbanized modern society is characterized by consuming a lot of energy in dense areas, and the stable supply of electric power used as clean energy, which is the most convenient to use, simple to transport, and pollution-free, This is an important factor throughout.

상기의 중요한 에너지인 전력의 안정적인 공급을 위해서는 낙뢰와 같은 자연적인 재해로부터 미연에 방류하여 안정적으로 공급되어야 함은 물론 전기의 고품질도 보장되어야 하는데, 발전소에서 발전된 고품질의 전력을 일반 수용가에까지 안정적으로 전달하려면 송전선은 전력 수용가와 직결된 배전선에서의 물질확보가 필요한 동시에 고품질의 전력 공급을 위해서는 양호한 접지가 필수적인 요소가 되고, 상기 접지는 전력이나 낙뢰로부터 인간을 보호하는 기능을 담당할 뿐만 아니라 전력사업의 측면에서 기준 전위를 제공하며, 낙뢰로부터 전력설비를 보호하고 계통의 고장시 귀로 전류의 통로가 되는 아주 중요한 역할을 담당하고 있을 뿐 아니라 정보화 사회로의 가속화가 진행되면서 일반 가정에서도 팩스밀리 또는 컴퓨터를 이용한 화상정보 및 인터넷등 의 설비가 이용되고 있어 사고의 피해와 피해액이 상대적으로 커지고 있으며, 특히 이러한 기기는 써지성의 급준파에 약한 측면이 있어 더욱더 전력의 고품질화를 요구하고 있다.The stable supply of power, the important energy above, must not only be discharged from natural disasters such as lightning strikes, but also be supplied stably and ensure the high quality of electricity. To do this, the transmission line needs to secure the material on the distribution line directly connected to the power consumer, and good grounding is essential for the high-quality power supply, and the grounding not only serves to protect humans from electric power or lightning, In addition to providing a reference potential in terms of protection, it plays a very important role in protecting power equipment from lightning strikes and providing a path for return current in the event of a system breakdown. Image information Due to the use of facilities such as the Internet and the Internet, the damage and the amount of damage are relatively large. In particular, these devices have a weak side to surge surges, and thus require higher power quality.

상기 전력은 발전소로부터 변전소로 전송되어 흔히 콘크리트 전주를 지지물로 하는 배전선을 따라 전주위의 주상 변압기를 통해 가정에 전달되는데, 배전선은 지중선과 가공선으로 분류되며, 지중선은 상대적으로 안정적인 전력을 공급하는데 우수한 반면, 건설비가 가공선에 비해 10배 이상 소요되고 사고의 파급이 크다는 문제가 있고, 특히 도심의 미관 등을 고려할 때 지중선이 바람직하나 이미 형성된 기존 도시에 지중선을 시공하기는 쉽지 않으므로 현재 가공선에 의한 전력의 전송이 함께 이루어지고 있는 것이다.The power is transmitted from the power plant to the substation and is often delivered to the home through the pole transformers around the pole along the distribution line supporting the concrete pole. The distribution line is classified into underground line and overhead line, and the underground line is excellent in supplying relatively stable power. On the other hand, there is a problem that the construction cost is more than 10 times that of overhead lines and the impact of accidents is large. Especially, considering the aesthetics of urban centers, underground lines are preferable, but it is not easy to construct underground lines in existing cities. Is being transmitted together.

또한, 변전소에서 여러 단계의 변압과정을 거친 전력을 각 가정 또는 건물 등의 일반 수용가로 공급하기 위해서는 각 지역에 일정 간격으로 설치되는 전주 등의 배전선로를 이용하게 되는데, 이와 같이 설치되는 배전선로에는 고전압의 흔촉 및 지락(地絡) 사고시 보호계전기의 동작을 확실히 하여 이상전압을 억제하고, 뇌(雷), 써지(surge) 등 이상전압에 의한 기기보호와 누전으로 인한 각종 전기재해 방지를 위하여 접지를 하게 되는 젓이다.In addition, in order to supply electric power that has undergone various stages of transformation in the substation to general consumers in each home or building, distribution lines such as electric poles installed at regular intervals in each region are used. To prevent abnormal voltages by ensuring the operation of protective relay in case of high voltage and ground fault, grounding for protection of equipment by abnormal voltage such as brain, surge, and various electric disasters due to short circuit It's done.

한편, 접지란 전력 설비의 사고나 절연불량, 전원회로나 전자장치에 뇌서지(Lightning Surge) 또는 개폐서지(Switching Surge) 와 같은 과도한 이상전압이 침입 한때 취급자를 감전사고로부터 보호하고 설비기기의 절연파괴를 방지할 뿐만 아니라 정보, 통신 설비에서 잡음을 제거하여 정보전송의 양질화를 이룩하는 기능성을 향상시키는 것으로 대지에 전기적 단자를 접속하는 것이다. 즉, 금속 또는 도전성 물체를 대지와 전기적으로 접속하여 그의 전위를 대지와 같은 전위 또는 전위차를 최소화시키는 수단을 말한다.On the other hand, grounding protects the operator from electric shock accidents and insulates the equipment when an excessive abnormal voltage such as lightning surge or switching surge occurs in the power equipment accident or poor insulation, power circuit or electronic device. In addition to preventing destruction, it also removes noise from information and communication facilities to improve the functionality of achieving high quality information transmission. That is, a means for electrically connecting a metal or a conductive object to the earth and minimizing the potential or potential difference thereof as the earth.

이를 위한 지금까지 배전선로의 접지공사는 전주를 매설할 수 있는 일정깊이의 구덩이를 굴착한 후, 상기 구덩이 일측으로 일정깊이와 폭을 갖는 구덩이를 하나 더 굴착하고, 상기 구덩이에 접지에 사용되는 다수의 접지봉을 햄머 등의 도구를 이용하여 타격시켜 매설한 다음, 상기 전주 내에서 인출되는 인출선과 상기 접지봉을 직렬 또는 병렬로 연결시키게 되며, 상기 작업이 완료되면 상기 구덩이에 흙과 같은 내용물을 체워 시공 및 설치작업이 이루어지게 되는 것이다.To this end, the grounding work of the distribution line has excavated a pit having a predetermined depth to bury electric poles, and then excavates one more pit having a predetermined depth and width to one side of the pit, and uses a plurality of grounds used for grounding the pit. The ground rod of the hammer is struck and buried by using a tool such as a hammer. Then, the lead wire drawn out in the pole and the ground rod are connected in series or in parallel. When the work is completed, the contents such as soil are installed in the pit. And installation is to be done.

하지만, 이와 같은 종래의 시공 작업에 의해 설치 완료된 전주는 배전선로가 광범위한 지역에 산재되어 있어 지역의 상황에 따라 소정의 접지 저항치를 얻기 위한 접지공사가 곤란하였고, 도심지에서 접지공사시 포장된 도로나 보도블럭을 파헤쳐야 되기 때문에 이에 따른 굴착 및 복구비가 과다하게 소요될 뿐만 아니라 지표면의 75㎝정도로 굴착된 지점에서 상기 접지봉을 해머로 타격하여 설치하므로 인해 상기 접지봉이 잘 들어가지 않게 되며, 들어가더라도 수도관, 가스관 및 통신 케이블 등의 기 매설된 지하매설물에 손상을 입히는 경우가 종종 발생하게 되는 문제가 있는 동시에 매설깊이가 깊을수록 접지저항치가 낮게 나타나게 됨으로써 소정의 접지저항치를 얻기가 어려운 문제점이 있었다.However, the electric poles installed by the conventional construction work are scattered in a wide range of distribution lines, so it is difficult to make a grounding work to obtain a predetermined ground resistance value according to the local situation. Due to the excavation of the sidewalk block, not only the excessive excavation and recovery costs are required, but also the ground rod is hardly entered due to the hammer being installed by hitting the ground rod with a hammer at the excavated point of about 75 cm of the ground surface. There is a problem that often causes damage to the underground buried underground, such as gas pipes and communication cables, and at the same time, the deeper the depth deeper the lower the ground resistance appears difficult to obtain a predetermined ground resistance.

또, 접지에 따른 접지저항치를 낮추기 위하여 접지봉을 직렬로 연결하여 시공하거나, 둘 이상의 접지봉을 일정거리 이상 이격하여 병렬로 시공하여 왔으나, 이 모두 시공이 어려울 뿐만 아니라 이로 인해 시공비가 과다하게 소요되고, 접지효과도 만족할 만한 수준이 못 되는 문제점이 있었다.In addition, in order to lower the ground resistance according to grounding, the ground rods are connected in series, or two or more ground rods have been installed in parallel with a predetermined distance, but all of them are not only difficult to construct, but also require excessive construction costs. There was a problem that the grounding effect is also not satisfactory.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 지하에 매설되는 전주의 하단부를 감싸는 도체인 접지우물통을 형성하여 인하선과 연결시킴으로써 인하선의 접지를 보다 손쉽고 간편하게 설치시공할 수 있고, 도전성 시멘트와 탄소섬유를 혼합한 접지우물통을 통해서 보다 높은 접지효과를 얻을 수 있는 전주용 접지판을 제공함에 그 목적이 있다.The present invention is to solve the problems as described above, by forming a grounding well that is a conductor surrounding the lower end of the pole buried underground to connect with the lowering line can be installed and installed more easily and easily the grounding of the lowering line, conductive cement and The purpose of the present invention is to provide a pole grounding plate that can obtain a higher grounding effect through a grounding well mixed with carbon fiber.
