Description

피뢰기능탑재형 가공배전용 고정기구{Lightning protection function-equipped fixing mechanism for overhead power distribution}Lightning protection function-equipped fixing mechanism for overhead power distribution

본 발명은 피뢰기능탑재형 가공배전용 고정기구에 관한 것이다.The present invention relates to a lightning protection type fixing mechanism for overhead power distribution.

일반적으로 발전소에서 생산된 전력은 송전탑 등의 송전선로를 통해 고압의 전력으로 각 변전소로 송전된 다음, 변전소에서는 여러 단계의 변압과정을 거쳐 각 가정 또는 건물 등의 수용가에서 사용할 수 있도록 케이블을 이용하여 각 지역으로 공급하게 되는 배전과정을 거치게 된다.In general, the power produced in the power plant is transmitted to each substation as high-voltage power through a transmission line such as a power transmission tower, and then the substation goes through several stages of transformation process using a cable so that it can be used by consumers in each house or building. It goes through a distribution process that is supplied to each region.

이때, 일반 수용가에 대란 전력공급은 일정간격으로 설치되는 전신주를 통해 공급하고, 각 전신주에서의 연결은 점퍼선을 이용하여 연결하게 된다.At this time, the power supply to general consumers is supplied through poles installed at regular intervals, and the connection at each pole is connected using jumper wires.

즉, 전신주에 연결하고자 하는 배전선을 전신주 상단 양측에 횡으로 설치되는 완금의 양측에서 애자를 통해 결합하고, 애자 사이를 점퍼선으로 연결하되, 연결되는 점퍼선은 완금의 상단에 설치되는 애자를 통해 지지될 수 있도록 시공하여 사용하였다.That is, the distribution wire to be connected to the utility pole is combined through insulators from both sides of the wangeum installed horizontally on both sides of the top of the pole, and the insulators are connected with jumper wires, but the connected jumper wire is installed on the top of the wangeum through insulators. It was constructed and used to be supported.

한편, 종래에는 전주로 낙뢰가 칠 시 낙뢰로부터 전주에 설치된 구성을 안전하게 보호하기 위하여 통상 피뢰기를 설치하며, 피뢰기에는 전주로부터 인출된 접지라인과 전기적으로 연결되는 피뢰라인을 구비한다.On the other hand, conventionally, a lightning arrester is usually installed in order to safely protect the configuration installed on the electric pole from lightning when lightning strikes the electric pole, and the lightning arrester is provided with a lightning protection line electrically connected to the ground line drawn from the electric pole.

그런데 종래에는 접지라인과 피뢰라인을 외부로 상호 연결함에 따라 바람이 불 경우 이에 의해 접지라인과 피뢰라인이 유동하게 되면서 미관상 보기 좋지 않았다.However, in the prior art, as the ground line and the lightning protection line are interconnected to the outside, when the wind blows, the ground line and the lightning protection line flow by this, which is not good in appearance.
