연접지가 가능한 가로등주의 기초 구조물{Base structure with common ground for streetlight columns}Base structure with common ground for streetlight columns}

본 발명은 가로등주의 기초 구조물에 관한 것으로서, 보다 상세하게는 다수 개의 가로등을 개별 접지 뿐만 아니라 연속 접속 접지하여 접지 저항을 감소시킬 수 있는 연접지가 가능한 가로등주의 기초 구조물에 관한 것이다.The present invention relates to a foundation structure for street lamps, and more particularly, to a ground structure of street lamps capable of a ground connection capable of reducing grounding resistance by continuously connecting a plurality of street lamps as well as individual grounding.

각종 가로등주(streetlight column)는 앵커볼트, 공급용 전선, 배출용 전선 및 콘크리트 블럭 등으로 구성되는 가로등 기초 구조물 상에 설치된다. 이러한 가로등주에 가설되는 전선이 누전될 때 사람 등이 접촉함으로서 야기되는 전기로 인한 각종 안전사고를 예방하기 위하여 가로등주를 미리 정해진 규정에 따라 가로등 기초를 통해 반드시 접지를 하도록 되어 있다. 이는 가로등주가 누전된 전선이 접촉되어 전기가 흐르는 상태에서 사람 등이 접촉하게 될 경우 예기치 못한 큰 사고로 이어지기 때문에 이와 같은 전기로 인한 각종 안전사고를 미연에 방지하기 위하여 불가피하게 마련된 것이다. 따라서, 국가에서는 가로등주를 3종 접지인 100Ω 이하로 유지되도록 법령으로 정해 놓고 있다.Various streetlight columns are installed on the streetlight base structure consisting of anchor bolts, supply wires, discharge wires, and concrete blocks. In order to prevent various safety accidents due to electricity caused by human contact when the electric wires installed on the street lamps are shorted, the street lamps must be grounded through the street lamp base according to a predetermined rule. This is inevitably provided in order to prevent various safety accidents caused by such electricity because the street lamp is a short-circuit wire contact the person is in contact with the electricity flows, leading to an unexpected big accident. Therefore, in the country, the statutory law sets street lamps to be kept below three types of ground, 100Ω.

종래 기술에 따른 가로등주는 콘크리트 블록을 양생할 때 하부에 노출되며 접지선과 전기적으로 연결되는 접지판을 매설하여 접지하였다. 상기에서 접지시 저항은 토양의 밀도에 따라 서로 다르게 된다. 즉, 토양의 밀도가 크면 저항값이 낮아지고, 마사토 등과 같이 토양의 밀도가 작으면 저항값이 증가된다.Street lamps according to the prior art were grounded by embedding a ground plate that is exposed to the bottom when the concrete block is cured and electrically connected to the ground wire. In the above grounding resistance is different depending on the density of the soil. In other words, if the soil density is large, the resistance value is low, and if the soil density is small, such as Masato, the resistance value is increased.

상기에서 접지 저항이 증가되면 접지 효율이 저하되어 누전시 가로등주를 통한 각종 안전사고를 방지하지 못하는 문제점이 있었다.When the grounding resistance is increased in the above, there is a problem that the grounding efficiency is deteriorated, and thus various safety accidents through the streetlight column are not prevented when the earth leakage occurs.

따라서, 본 발명의 목적은 토양의 상태와 무관하게 접지 저항을 감소시켜 누전시 가로등주를 통한 각종 안전사고를 방지할 수 있는 연접지가 가능한 가로등주의 기초 구조물을 제공함에 있다.Accordingly, it is an object of the present invention to provide a ground structure of a street lamp column capable of a ground connection that can reduce the ground resistance irrespective of the state of the soil to prevent various safety accidents through the street lamp column in the event of a short circuit.

Includes a ground plate installed in electrical connection with the fixed ground wire The.

상기에서 접지연결판은 상기 고정접지선, 공급용 연접지선 및 배출용 연접지선과 전기적으로 병렬 접속되도록 삼지(三指) 구조의 동판으로 형성된다.In the above, the ground connecting plate is formed of a copper plate having a triangular structure so as to be electrically connected in parallel with the fixed ground wire, the supply connection ground wire and the discharge connection ground wire.

따라서, 본 발명은 다수 개의 가로등주를 병렬 연결되도록 연접지하는 것에 의해 접지 저항을 저하시키므로 누전시 가로등주를 통한 각종 안전사고를 방지할 수 있는 이점이 있다.Therefore, the present invention lowers the grounding resistance by connecting a plurality of street lamps in parallel so as to be connected in parallel, thereby preventing various safety accidents through the street lamps during a short circuit.
