가공송전선로의 연결구조{Connection structure of an overhead electric power line} Connection structure of an overhead electric power line

본 발명은 가공송전선로의 연결구조에 관한 것이다. The present invention relates to a connection structure of overhead transmission line.

일반적으로, 발전소에 발생되는 대전력은 송전탑 등의 송전선로를 통해 고압의 전력으로 각 변전소로 송전된 다음, 변전소에서 여러 단계의 변압과정을 거쳐 각 가정 또는 건물 등의 수용가에서 사용할 수 있도록 케이블을 이용하여 각 지역으로 공급하게 되는 배전과정을 거치게 되는 것은 주지된 사실이다.In general, the large power generated in the power plant is transmitted to each substation with high voltage power through transmission lines such as power transmission towers, and then the cable is used for use in each home or building through a multi-stage transformation process at the substation. It is a well known fact that the distribution process that is supplied to each region is used.

이때, 일반 수용가에 대한 전력공급은 일정간격으로 설치되는 전주를 통해 공급하고, 각 전주에서의 가공전선의 연결은 완철의 하방으로 늘어진 점퍼선을 이용하여 연결하게 된다.At this time, the power supply to the general customer is supplied through the poles installed at regular intervals, and the connection of the overhead wires in each pole is connected by using jumper wires stretched downwards.

이러한 종래의 가공전선 연결은 풍압에 따른 전주와의 접촉으로 인해 가공전선로의 고장이 빈번하게 발생하였다. The conventional overhead wire connection frequently causes breakdown of the overhead wire due to contact with the pole due to wind pressure.
