접지판{eletric ground plate}Ground plate

본 발명은 전주나 변압기등의 접지선과 연결되어 서지전류를 지중으로 방전하는 접지판에 관한 것이다.The present invention relates to a ground plate which is connected to a ground wire such as a pole or a transformer to discharge a surge current into the ground.

접지선과 연결되어 서지전류를 전기장치나 인명에 손상이 가지 않도록 빠른 시간안에 서지전류를 지중으로 방전시키는 다양한 연구들이 진행되어 왔으며, 그 중 하나가 실용신안 등록출원 제20-2001-0021881호(고안의 명칭: 전주용 접지판)이라 할 수 있다.Various studies have been conducted to discharge the surge current into the ground quickly so that the surge current is not damaged to the electric device or human life in connection with the ground wire, and one of them is Utility Model Registration Application No. 20-2001-0021881 The name of the pole: ground pole for electric pole).

도 1은 실용신안 등록출원 제20-2001-0021881호의 접지판의 정면도이다.1 is a front view of a ground plate of Utility Model Registration Application No. 20-2001-0021881.

도 1에 도시된 접지판(10)은 전주에 시공 설치되며 값이 싸고 전도성이 우수한 동으로 이루어지는 판체(11)로 형성되되, 상기 판체(11)의 일측에는 다수의 돌기로 이루어진 체결부(12)가 형성되고, 상기 판체(11)의 타측에는 상기The ground plate 10 shown in FIG. 1 is installed in a pole and is formed of a plate body 11 made of copper having low cost and excellent conductivity, and one side of the plate body 11 includes a fastening part 12 formed of a plurality of protrusions. ) Is formed, and the other side of the plate body 11

체결부 (12)가 삽입되어 안정적으로 체결시키기 위해 대응하는 다수의 체결홈(13)이 형성되며, 전주내에 설치된 인출선을 연결시키기 위해 상기 판체(11)의 소정의 위치에 스폿트 용접되는 접지봉(14)이 형성되어 이루어진다.A plurality of fastening grooves 13 are formed to fasten and fasten the fastening part 12, and a ground rod is spot welded to a predetermined position of the plate body 11 to connect a lead wire installed in the electric pole. 14 is formed.

그러나, 이러한 접지판(10)은 대지와 접촉되는 면이 작아 대지와 접지판 사 이에 많은 저항이 발생되게 되어 방전속도가 느리게 되고, 접지선과 접지판의 접촉부위가 작아 오히려 전주의 전위를 높힐 위험성이 내포되어 있으며, 외부 충격에 접지판(10)이 변형되는 경우가 많이 발생되게 된다. However, the ground plate 10 has a small contact surface with the ground, which causes a lot of resistance between the ground and the ground plate, resulting in a slow discharge rate, and a small contact portion between the ground wire and the ground plate, thus increasing the potential of the pole. This is enclosed, and the ground plate 10 is often deformed due to external impact.

본 발명은 이러한 문제점을 해결하기 위한 것으로, 본 발명의 해결과제는 접지판과 접지선의 접촉면적과 접지판과 대지 사이의 접촉면적을 넓히도록 하는 한편, 접지판으로부터의 방전이 용이하도록 함으로써 접지선으로부터 서지전류가 신속히 방전되도록 하는 접지판 구조를 제공하기 위한 것이다.The present invention is to solve this problem, the problem of the present invention is to increase the contact area between the ground plate and the ground wire and the contact area between the ground plate and the ground, and to facilitate the discharge from the ground plate from the ground wire An object of the present invention is to provide a ground plate structure for quickly discharging a surge current.

또한, 본 발멸의 다른 해결수단은 접지저항 저감효과가 우수하며 외부 충격에 강한 접지판을 제공하기 위한 것이다.In addition, another solution of the present invention is to provide a ground plate excellent in the effect of reducing ground resistance and resistant to external impact.

상기 과제를 해결하기 위한 본 발명의 해결수단은 양도체로 이루어지며 산과 골이 교대로 형성되는 웨이브 판체; 상기 웨이브 판체의 산과 골 중 어느 하나에 길이방향으로 설치되며 접지선과 결합되는 접지환봉을 포함하는 것이다.Solving means of the present invention for solving the above problems is made of a good conductor and the wave plate body is formed alternately with the hill; It is installed in any one of the peaks and valleys of the wave plate body to include a grounding rod coupled to the ground wire.
