본 발명은 피뢰구조장착 가공배전라인 고정기기에 관한 것이다.The present invention relates to an overhead distribution line fixing device equipped with a lightning protection structure.

일반적으로 고압 또는 특고압(23㎸) 가공 배전 선로 상에서 전력선의 접속 개소는 절연 전선, 인류 클램프, 인류 클램프 커버 및 애자 등으로 구성되어 지지물(전주)에 접속된다. In general, the connection point of the power line on the high-voltage or extra-high voltage (23 kV) overhead distribution line is composed of an insulated wire, a human clamp, a human clamp cover and an insulator, and is connected to a support (electric pole).

애자와 전선을 접속하는 인류 클램프에는 인류 클램프 커버가 씌워져 접속 개소의 충전 부위가 절연되어 사용될 수 있다. The human clamp cover connecting the insulator and the electric wire is covered with the human clamp cover, so the charging part of the connection point can be insulated and used.

이러한 경우는 활선 작업과 같은 인위적인 접근이 없는 전제하에 이루어질 수 있다. This case can be done under the premise that there is no artificial approach such as live wire work.

따라서, 활선 작업시에는 작업자나 작업용 장비의 접근이 수시로 이루어지기 때문에 안전을 위해 충분한 절연 특성과 기계적으로 우수한 강도를 가진 활선 작업용 절연커버가 필수적으로 갖추어져야만 한다.Therefore, when working with a live wire, since a worker or equipment for work is frequently accessed, an insulating cover for a live wire operation having sufficient insulation properties and mechanically excellent strength for safety must be essential.

이러한 절연커버와 관련된 종래 기술로는 대한민국 등록특허 제10-2091609호(가공배전선로 활선작업용 신축형 전선 커버)가 있으며, 여기에는 가공배전선로의 활선작업시 작업범위에 따라 길이조절이 가능하여 작업 범위를 모두 커버한 상태에서 안전하게 활선작업을 진행할 수 있는 기술이 개시되어 있다.As a prior art related to such an insulation cover, there is Republic of Korea Patent Registration No. 10-2091609 (extensible wire cover for live wire work of overhead distribution lines), which allows length adjustment according to the work range during live wire work of overhead distribution lines. A technology that can safely perform live wire work in a state in which the entire range is covered is disclosed.

한편, 낙뢰로부터 가공전선 및 애자를 보호하기 위하여 전주의 상부에는 피뢰기를 설치하고, 피뢰기로부터 인출된 접지선은 지중에 매립해 낙뢰를 지중으로 흘려보낸다.On the other hand, to protect overhead wires and insulators from lightning, a lightning arrester is installed on the upper part of the pole, and the ground wire drawn from the arrester is buried in the ground and the lightning flows into the underground.

그런데 이와 같은 접지선은 통상 전주의 외부로 노출됨에 따라 외력에 쉽게 흔들리기 쉽고 이로 인해 주변 전선과의 접촉으로 인하여 전기합선을 유발하는 등의 문제가 있었다.However, as such a ground wire is usually exposed to the outside of the electric pole, it is easily shaken by an external force, and this has a problem such as causing an electric short due to contact with the surrounding electric wire.

상기 제1·2바디(431A,431B)는 전체적으로‘T’자 형상을 이루며, 분할형성되어 상호 결합된다. 이러한 제1·2바디(431A,431B)는 양측면과 하단만 절개되어 있어 강제로 벌리거나 오므리게 할 수 있다. 또한, 제1·2바디(431A,431B)의 내부에는 전후방향으로 슬리브수용부(432)가 형성되고, 상하방향으로 분기선감착부(433)가 일체로 형성된다. 여기서 슬리브수용부(432)에는 분기슬리브(410)가 삽탈가능하게 수용되고, 분기선감착부(433)에는 슬리브수용부(432)에 감착된 분기선(L')이 삽탈가능하게 수용된다. The first and second bodies 431A and 431B form a 'T' shape as a whole, are divided and are coupled to each other. These first and second bodies (431A, 431B) can be forcibly opened or closed since only the both sides and the lower end are incised. In addition, the sleeve receiving portion 432 is formed in the front and rear directions inside the first and second bodies 431A and 431B, and the branch line fitting portion 433 is integrally formed in the vertical direction.

계속해서, 상기 랙크유닛(500)은 바디(510)와 커버(520) 및 절연애자(530)로 구성된 것으로서, 본 실시 예의 경우 전신주(P)의 외주면에 고정수단(앵커볼트)을 매개로 설치되어 접지선(GL)과 분기선(L')을 가이드하는 역할을 한다.Subsequently, the rack unit 500 is composed of a body 510, a cover 520, and an insulating insulator 530, and in this embodiment, a fixing means (anchor bolt) is installed on the outer circumferential surface of the telephone pole P as a medium. It serves to guide the ground line (GL) and the branch line (L').

상기 바디(510)는 양단이 서로 이격되게 직사각형상으로 밴딩(또는 절곡)된 부재로서, 이격된 양단은 사선으로 경사진 경사부(511)가 일체로 마련된다.The body 510 is a member bent (or bent) in a rectangular shape so that both ends are spaced apart from each other, and both ends of the body 510 are provided integrally with inclined portions 511 inclined at an oblique angle.

상기 커버(520)는 바디(510)의 이격된 양단 사이에 회전가능하게 배치되어 양단 사이를 개폐하는 역할을 한다. 이러한 커버(520)의 양단에는 바디(510)의 경사부(511)에 대응되는 경사부(521)가 일체로 형성되어 서로 맞대어진다.The cover 520 is rotatably disposed between both ends of the body 510 spaced apart from each other and serves to open and close between both ends. At both ends of the cover 520 , inclined portions 521 corresponding to the inclined portions 511 of the body 510 are integrally formed to face each other.

일 예로서, 상기 커버(520)를 반시계방향으로 회전시켜주게 되면 바디(510)의 경사부(511)와 커버(520)의 경사부(521)가 서로 이격되면서 개방되며, 이렇게 개방된 개구부를 통해 접지선(GL)과 분기선(L')을 각각 삽입하면된다. 그리고 커버(520)를 시계방향으로 회전시켜 주게 되면 바디(510)의 경사부(511)와 커버(520)의 경사부(521)가 서로 맞대어지면서 폐쇄되며, 이로 인해 접지선(GL)과 분기선(L')은 랙크유닛(500)으로부터의 이탈을 제한받게 된다.As an example, when the cover 520 is rotated counterclockwise, the inclined portion 511 of the body 510 and the inclined portion 521 of the cover 520 are opened while being spaced apart from each other, and thus the open opening Just insert the ground line (GL) and the branch line (L') through the And when the cover 520 is rotated clockwise, the inclined portion 511 of the body 510 and the inclined portion 521 of the cover 520 are abutted to each other and closed, thereby causing the ground line GL and the branch line ( L') is restricted from leaving the rack unit (500).

상기 절연애자(530)은 한 쌍이 바디(510)에 수용되어 볼트(B)와 너트(N)를 매개로 바디(510)에 회전가능하게 설치되어서 접지선(GL)과 분기선(L')을 절연 및 가이드하는 역할을 한다.A pair of insulators 530 is accommodated in the body 510 and is rotatably installed on the body 510 via a bolt (B) and a nut (N) to insulate the ground line (GL) and the branch line (L'). and serves as a guide.

상기 한 쌍의 절연애자(530) 중 어느 하나에는 커버(520)가 볼트(B)와 너트(N)를 매개로 회전가능하게 설치된다.A cover 520 is rotatably installed on any one of the pair of insulators 530 via a bolt (B) and a nut (N).

도 5a 내지 도 5c는 본 발명에 따른 피뢰구조장착 가공배전라인 고정기기에서 분기유닛의 사용상태를 설명하기 위한 도면으로서, 이를 참조하여 설명하면 다음과 같다.5A to 5C are views for explaining a state of use of a branch unit in an overhead distribution line fixing device equipped with a lightning protection structure according to the present invention, which will be described with reference to the following.

먼저, 가공배전선(L)의 외주면으로 분기슬리브(410)를 끼워 넣은 다음 분기슬리브(410)의 양단부에 마련된 클램핑부(411)를 각각 도구를 이용해 가압한다.First, the branch sleeve 410 is inserted into the outer circumferential surface of the overhead distribution line (L), and then the clamping parts 411 provided at both ends of the branch sleeve 410 are pressed using a tool, respectively.

상기와 같이 클램핑부(411)는 가압되어 오므려지면서 가공배전선(L)에 고정되며, 이때 클램핑부(411)의 내면에 마련된 고정핀(413)은 가공배전선(L)의 내부로 파고 들어감에 따라 가공배전선(L)과 클램핑부(411)는 보다 견고하게 고정된다.As described above, the clamping part 411 is fixed to the overhead distribution line (L) while being pressed and closed. Accordingly, the overhead distribution line L and the clamping portion 411 are more firmly fixed.

상기와 같이 가공배전선(L)에 분기슬리브(410)가 장착되면, 분기선(L')을 분기슬리브(410)에 감아 고정하는데, 이를 좀 더 구체적으로 설명하면 다음과 같다.When the branch sleeve 410 is mounted on the overhead distribution line L as described above, the branch line L' is wound around the branch sleeve 410 and fixed, which will be described in more detail as follows.

먼저, 분기슬리브(410)의 분기선안착부(412)에 분기선(L')을 감아 준 상태에서 분기선고정링(420)을 이용해 감겨진 끝단부분을 가압해 풀어지지 않게 고정한다.First, in a state in which the branch line L' is wound on the branch line seating portion 412 of the branch sleeve 410, the wound end portion is pressed using the branch wire fixing ring 420 to fix it so as not to be loosened.

이때, 상기 분기선(L')은 자중에 의해 분기선안착부(412)의 내면에 강하게 밀착되는데, 이 과정에 분기선안착부(412)에 마련된 고정핀(413)이 분기선(L')에 꽂히게 되고, 이에 따라 분기슬리브(410)와 분기선(L')은 일체형 구조를 이루게 된다.At this time, the branch line L' is strongly adhered to the inner surface of the branch line seating part 412 by its own weight. Accordingly, the branch sleeve 410 and the branch line L' form an integrated structure.

상기와 같이 분기슬리브(410)에 분기선(L')이 연결되면, 하우징(430)을 이용해 분기슬리브(410)와 분기선(L')을 감싸 주면 분기작업이 완료된다.When the branch line L' is connected to the branch sleeve 410 as described above, the branching operation is completed when the branch sleeve 410 and the branch line L' are wrapped using the housing 430.

상기와 같이 분기작업이 완료되면, 접지선(GL)과 분기선(L')은 랙크유닛(500)에 안정적으로 결합시켜준다.When the branch operation is completed as described above, the ground wire (GL) and the branch wire (L') are stably coupled to the rack unit (500).

본 실시 예에 의하면, 상기 랙크유닛(500)에 접지선(GL)과 분기선(L')이 삽탈가능하게 끼워져 가이드됨에 따라 접지선(GL)과 분기선(L')으로 외력이 작용하도라도 횡진을 최대한 억제할 수 있으며, 이에 따라 접지선(GL)과 분기선(L') 간의 충돌을 최대한 억제할 수 있는 이점이 있다. According to this embodiment, as the ground wire (GL) and the branch line (L') are inserted and detached to the rack unit 500 and guided, the transverse movement is maximized even if an external force is applied to the ground wire (GL) and the branch line (L'). It can be suppressed, and accordingly, there is an advantage in that the collision between the ground line GL and the branch line L' can be suppressed as much as possible.

본 발명은 기재된 구체적인 실시 예에 대해서만 상세히 설명되었지만 본 발명의 기술사상범위 내에서 다양하게 변형 및 수정할 수 있음은 당업자에 있어서 당연한 것이며, 이러한 변형 및 수정이 첨부된 특허청구범위에 속함은 당연한 것이다.Although the present invention has been described in detail only with respect to the specific embodiments described, it is natural for those skilled in the art that various changes and modifications can be made within the technical spirit of the present invention, and it is natural that such variations and modifications belong to the appended claims.
