본 발명은 접지장치 연계형 콘크리트 전주에 관한 것으로서, 보다 상세하게는 간단한 구조를 가지므로 시공이 편리함은 물론 비용이 저렴하면서 접지 성능을 극대화할 수 있는 접지장치 연계형 콘크리트 전주에 관한 것이다.The present invention relates to a grounding device-linked concrete pole, more specifically, because it has a simple structure, the construction is convenient and of course cheaper and relates to a grounding device-linked concrete pole that can maximize the grounding performance.

일반적으로, 발전소로부터 변전소로 전송되는 전력은 흔히 콘크리트 전주를 지지물로 하는 배전선을 따라 전주 위의 주상 변압기를 통해 가정에 전달된다. 상기 배전선은 지중선과 가공선으로 분류되며, 지중선은 상대적으로 안정적인 전력을 공급하는데 우수한 반면 건설비가 가공선에 비해 10배 이상 소요되고 사고의 파급이 크다는 단점도 있다. 특히, 도심의 미관 등을 고려하면 지중선이 바람직하지만 이미 형성된 기존 도시에 지중선을 시공하기는 쉽지 않으므로 지금까지는 가공선에 의한 전력의 전송이 주류를 이루고 있다. 또한, 가공선은 지지물로서 콘크리트 전주를 대부분 사용하고 있다.In general, power transmitted from a power plant to a substation is often delivered to the home via a pole transformer above the pole along a distribution line supported by a concrete pole. The distribution lines are classified into underground lines and overhead lines, and underground lines are excellent in supplying relatively stable electric power, but have a disadvantage in that construction costs are more than 10 times higher than those in overhead lines and accidents are large. In particular, considering the beauty of the city, underground lines are preferable, but it is not easy to construct underground lines in existing cities that have already been formed, so far, the transmission of electric power by overhead lines has been the mainstream. In addition, the overhead line mostly uses a concrete pole as a support.

한편, 발전소에서 발전된 전력을 일반 가정으로 안정적으로 전달하려면 송전선은 물론 전력 수용가에 직결된 배전선에서의 품질확보가 필요하다. 그런데, 고품질의 안정적인 전력 공급을 위해서는 양호한 접지 시스템을 구비하는 것이 바람직 하다.On the other hand, in order to stably transfer electric power generated from power plants to homes, it is necessary to secure the quality of power lines as well as power lines directly connected to electric power consumers. However, it is desirable to have a good grounding system for high quality and stable power supply.

일반적으로 우리나라의 경우, 22.9KV-y 특고압 배전선은 5경간마다, 220V, 380V, 저압은 3경간마다 중성선을 대지와 연결시킴으로써 수용 장소까지 전력을 공급하게 된다. 중성선을 대지와 연결시키는 것을 접지 시스템이라고 한다.In general, in Korea, the 22.9KV-y high-voltage distribution line connects the neutral to the ground every 5 spans, 220V, 380V, and the low voltage every 3 spans to supply power to the receiving site. Connecting the neutral to the earth is called a grounding system.

접지 시스템은 전력이나 낙뢰로부터 인간을 보호함은 물론 전력 사업의 측면에서 기준 전위를 제공하고 낙뢰로부터 전력설비를 보호한다. 또한, 접지 시스템은 계통의 장애 발생시 귀로 전류의 통로가 되는 아주 중요한 역할을 한다.The grounding system not only protects humans from power or lightning, but also provides a reference potential in terms of the electricity business and protects the electrical installation from lightning. In addition, the grounding system plays a very important role as a path for the return current in the event of a system failure.

지금까지 알려진 콘크리트 전주용 접지 시스템은 대한민국 특허 공개번호 제2000-74099호, 대한민국 특허 공개번호 제2000-41069호, 및 대한민국 실용신안등록 번호 제20-0288758호 등에 개시되어 있다.The grounding system for concrete poles so far known is disclosed in Korean Patent Publication No. 2000-74099, Korean Patent Publication No. 2000-41069, and Korean Utility Model Registration No. 20-0288758.

This takes excessively, and the stability of the grounding system has a weak disadvantage.

둘째, 대한민국 특허 공개번호 제2000-41069호에 개시된 접지 시스템은 원통형의 접지 동판을 이용하기 때문에 비용이 과다하게 소요되며, 결합밴드를 이용하여 바늘 접지극을 별도로 부착해야 하므로 시공이 불편한 단점이 있었다.Second, the grounding system disclosed in Korean Patent Laid-Open No. 2000-41069 takes an excessive cost because it uses a cylindrical ground copper plate, and has a disadvantage in that construction is inconvenient because the needle ground electrode must be separately attached using a coupling band.

셋째, 대한민국 실용신안등록 번호 제20-0288758호에 개시된 접지 시스템은 접지동봉을 나연동선을 이용하여 전주의 철근에 설치하기 때문에 과다한 비용과 시공상의 불편함이 따르는 문제점이 있었다.Third, the grounding system disclosed in Korean Utility Model Registration No. 20-0288758 has a problem of excessive cost and construction inconvenience because the grounding rod is installed on the reinforcing bar by using bare copper wire.
