Description

고압선의 처짐방지장치{Prevention apparatus for drooping of power cable}Deflection apparatus of high voltage cable {Prevention apparatus for drooping of power cable}

본 발명은 고압선을 지지해주는 전주의 상부에 설치되어 전주에 지지되는 고압선을 안정적으로 지지하면서 전주에 전달되는 풍하중 및 케이블의 하중을 최소화 할 수 있도록 한 고압선의 처짐방지장치에 관한 것이다.
The present invention relates to a device for preventing sag of a high voltage cable, which is installed at an upper portion of a pole supporting a high voltage cable, to stably support a high voltage cable supported by a pole, thereby minimizing wind load and cable load transmitted to the pole.

일반적으로, 전력은 발전소로부터 송전철탑 등을 사용한 송전선로를 통해 변전소로 전송되어 여러 단계의 변압과정을 거친 후 전주의 배전선로를 따라 일반 수용가(가정)로 공급하게 된다. 이때, 전주에 설치되는 배전선로에는 뇌(雷) , 써지(surge) 등 이상전압에 의한 기기보호와 누전으로 인한 각종 전기재해 방지를 위하여 배전선에서의 물질확보 및 양호한 접지를 필요로하였고, 상기한 접지는 전력이나 낙뢰로부터 인간 및 전력설비 보호기능을 갖는다.In general, electric power is transmitted from a power plant to a substation through a transmission line using a transmission tower, etc., and is then supplied to general customers (homes) along the distribution line of Jeonju after several stages of transformation. At this time, the distribution lines installed in Jeonju were required to secure the material and good grounding in the distribution lines in order to protect the equipment by abnormal voltages such as thunder and surge, and to prevent various electrical disasters due to short circuits. Grounding provides protection for humans and utilities from power and lightning strikes.

종래의 송배전선로는 지중이나 공중에 설치되는 데, 공중에 설치될 경우 철탑 또는 전주 등의 지지물을 이용하여 가공 설치하게 된다.
Conventional transmission and distribution lines are installed underground or in the air, when installed in the air is installed by using a support such as a steel tower or electric pole.

상기 지지물 중 전주에 설치되는 송배전선로는 3상 4선식, 3상 3선식 또는 단상 2선식으로 전주 1본에 주로 3선1조로 하여 전주의 상하단으로 설치되는 데, 이 경우에는 최대 2회선으로 제한된다. 물론, 송전탑을 이용한 송전선로일 경우에는 3회선 이상이 설치되기도 한다.The transmission and distribution lines installed in Jeonju among the supports are installed in the upper and lower ends of Jeonju, mainly consisting of one set of three wires in one pole of 3-phase 4-wire, 3-phase 3-wire or single-phase 2-wire. do. Of course, in the case of a transmission line using a transmission tower, more than three lines may be installed.

이와 같이 기존의 가공 케이블을 이용할 경우에는 1회선당 3~4선 1조로 하여 전선로가 구성됨에 따라 전주의 설치공간과 전주의 길이 등의 요인에 따라 전주 1본에 설치할 수 있는 회선이 2회선 이하로 제한되어 있다.In the case of using the existing overhead cable, three to four wires per line is composed of one cable line. Therefore, depending on factors such as the installation space and the length of the pole, the number of lines that can be installed in one pole is less than two lines. Limited to.

여기서, 수용가 측 각 전주의 송배전 전선은 전주 상단으로 횡설되는 상부지지대(완금)에 팽팽한 긴장력을 갖도록 배선되고, 상부 지지대에 고정된 라인 포스트 애자(Line post:핀애자)를 통해 점퍼선과 상향 또는 하향으로 연결하게 된다.Here, the transmission and distribution wires of each pole of the customer side are wired so as to have a tension in the upper support (complete) which is rolled up to the upper end of the pole, and the jumper line and the upward or downward through the line post insulator (Line post: pin insulator) fixed to the upper support. Will be connected.

그러나 이러한 송배전 전선은 자체 하중과 외기의 영향에 의해 일정 기간이 경과하면 늘어지는 현상이 초래되어 도심 경관을 크게 저해하였음은 물론이고 바람과 같은 외부 기후 요인에 의해 쉽게 흔들려 마찰에 의한 합선 사고와 단전 사고가 초래되는 문제점이 있다.
