Description

배전 전주용 접지판{EARTH PLATE OF ELECTRIC SUPPLY POLES}Ground plate for distribution poles {EARTH PLATE OF ELECTRIC SUPPLY POLES}

본 발명은 배전 전주용 접지판에 관한 것으로서, 보다 구체적으로는 전주에 시공되는 접지 구조를 용이하게 설치하도록 함과 동시에 구성요소들간의 고정력을 개선시킨 배전 전주용 접지판에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grounding plate for power distribution poles, and more particularly, to a grounding plate for power distribution poles, which allows easy installation of a grounding structure installed in poles and at the same time improves a fixing force between components.

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. 상기의 중요한 에너지인 전력의 안정적인 공급을 위해서는 낙뢰와 같은 자연적인 재해를 미연에 방류하여 안정적으로 전력이 공급되어야 함은 물론 전기의 고품질도 보장되어야 하는데, 발전소에서 발전된 고품질의 전력을 일반 수용가에까지 안정적으로 전달하려면 송전선은 전력 수용가와 직결된 배전선에서의 물질 확보가 필요한 동시에 고품질의 전력 공급을 위해서는 양호한 접지가 필수적인 요소가 되고, 그러한 접지는 전력이나 낙뢰로부 터 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 팩시밀리 또는 컴퓨터를 이용한 화상정보 및 인터넷 등의 설비가 이용되고 있어 사고의 피해와 피해액이 상대적으로 커지고 있으며, 특히 이러한 기기는 써지성의 급준파에 약한 측면이 있어 더욱더 전력의 고품질화를 요구하고 있다. 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 미관등을 고려할 때 지중선이 바람직하나 이미 형성된 기존 도시에 지중선을 시공하기는 쉽지 않으므로 현재 가공선에 의한 전력의 전송이 함께 이루어지고 있는 것이다. 또한, 변전소에서 여러단계의 변압과정을 거친 전력을 각 가정 또는 건물등의 일반 수용가로 공급하기 위해서는 각 지역에 일정 간격으로 설치되는 전주등의 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 것이다.In general, the modernized, industrialized, and urbanized modern society is characterized by consuming a large amount of energy in dense areas, and the stable supply of electric power used as clean energy, which is the most convenient, simple to transport, and pollution-free among these energy, This is an important factor throughout. For the stable supply of electric power, which is the important energy, the natural disasters such as lightning must be discharged in a stable manner and the power must be supplied stably, and the high quality of electricity must be guaranteed. Transmission lines require material acquisition on the distribution line directly connected to the consumer, while good grounding is essential for high-quality power supply, which serves to protect humans from power and lightning strikes. In addition, it provides a reference potential in terms of electric power business, plays a very important role in protecting electric power equipment from lightning strikes and providing a path of return current in the event of a system breakdown. Or computerized Information, and it is used an equipment, such as the Internet, and the amount of damage and the damage of an accident with a relatively larger, in particular such a device would require a further electric power of high quality it is weak in terms of class junpa sex written. Electric power is transferred from the power plant to the substation and is often delivered to the home via pole-type transformers around the poles, along the distribution lines supporting the concrete poles, which are classified as underground lines and overhead lines, while underground lines are excellent at providing relatively stable power. The cost of construction is more than 10 times that of overhead lines and the impact of accidents is high. Especially, considering the beauty of the city, underground lines are preferable, but it is not easy to construct underground lines in existing cities. This is happening together. In addition, in order to supply electric power that has undergone several stages of transformation processes at substations to general consumers such as homes or buildings, distribution lines such as electric poles installed at regular intervals in each region are used. To prevent abnormal voltages by ensuring the operation of the protective relay in the event of high voltage or ground fault, and to protect the equipment by abnormal voltages such as brain and surge, and to prevent various electrical disasters due to short circuit. Will be.
