송전케이블의 위치변동제한 및 안내용 완철{Horizontal Supporting For Location Restrictive And Guide Of Underground Power Cable}Horizontal Supporting For Location Restrictive And Guide Of Underground Power Cable

본 발명은 풍력에 의해 애자가 받는 외력을 최소화시키고 송전케이블이 받는 장력을 조정해서 안정된 송전케이블의 상태를 유지토록 할 수 있는 송전케이블의 위치변동제한 및 안내용 완철에 관한 것이다.
The present invention relates to limiting the fluctuation of the position of the transmission cable and guide wires that can maintain the state of the stable transmission cable by minimizing the external force received by the wind and adjusting the tension received by the transmission cable.

일반적으로 특고압 전기의 송전은 일정간격으로 설치되는 철탑의 완철에 애자를 설치하고, 애자를 매개로 송전케이블을 설치하여 연결하게 된다.In general, the transmission of extra high voltage electricity is connected to the insulator on the complete iron tower installed at regular intervals, and the transmission cable is installed through the insulator.

그런데, 상기와 같은 송전케이블은 그 길이가 상당할 뿐만 아니라, 바람에 의해 송전케이블이 쉽게 요동치는 경우가 자주 발생하였고, 이러한 송전케이블의 요동에 의해 진동과 충격이 애자에 그대로 전달되어 애자가 완철에서 이탈되거나 심하게는 애자가 손상되어 절연기능을 상실하는 문제가 있었다.However, the transmission cable as described above has a considerable length, and the transmission cable frequently swings easily due to the wind. The vibration and shock are transmitted to the insulator by the shaking of the transmission cable, so that the insulator is completed. There was a problem that the insulation function was lost because of insulated or severely damaged insulator.

그로 인하여, 보수를 하고자 하는 경우 전기를 단전한 상태에서 작업자가 올라가 직접작업해야 함으로, 간혹 있을 잔존전류로 인한 감전사 및 고소작업에 따른 추락사로부터 작업자를 지키기 어려운 문제가 있으며, 단전시 전력을 사용해야 하는 세대들의 크나큰 불편과 원성을 초래하는 문제가 있었다.Therefore, in order to perform repairs, the worker must go up and work directly in the state of disconnection of electricity, which sometimes makes it difficult to protect the worker from the electrocution caused by the residual current and the fall due to the high-altitude operation. There was a problem that caused great inconvenience and originality of the generations.

한편, 송전케이블은 무한히 긴 전선을 적용할 수 없기 때문에 일정 구간마다 점퍼선을 연결하게 되는데, 이때 송전선과 점퍼선을 고정하여 전기적으로 연결하는 기구로서 커넥터가 이용된다.On the other hand, since the transmission cable is not applicable to infinitely long wires are connected to the jumper wire every certain interval, the connector is used as a mechanism for electrically connecting the transmission line and the jumper wire.

하지만, 종래의 커넥터는 단순히 송전케이블과 점퍼선을 고정하여 전기적으로 연결하는 기능만 있을 뿐, 이물질(예를 들면, 비(雨)나 표면에 은박이 입혀진 풍선)이 커넥터와 접촉하게 되면, 자칫 전기합선으로 인해 화재가 발생하는 등 이물질에 상당히 취약한 문제가 있어, 이를 해소하기 위한 연구가 활발히 진행되어져 왔다.
However, the conventional connector merely has a function of electrically connecting the power transmission cable and jumper wires, and when foreign matter (for example, a rain or a balloon covered with silver foil on the surface) comes into contact with the connector, Since there is a problem that is extremely vulnerable to foreign matters such as a fire caused by an electric short circuit, research has been actively conducted to solve it.

본 발명은 상기와 같은 문제를 해소하기 위하여 안출된 것으로서, 송전케이블을 지지하는 애자를 견실하게 고정하면서 바람 등과 같은 외력에 의해 송전케이블이 흔들리거나 요동치는 것을 감쇄시켜 송전케이블의 연결부위 및 철탑을 보호할 수 있는 송전케이블의 위치변동제한 및 안내용 완철을 제공하려는데 그 목적이 있다.
