Description

라인포스트 애자용 전력선홀더Power Line Holder for Line Post Insulator
본 발명은 라인포스트 애자의 상부에 구비되어 전력선을 압박 지지하기 위한 전력선홀더에 관한 것이다.The present invention relates to a power line holder provided on an upper portion of a line post insulator for pressing and supporting a power line.
일반적으로 애자는 철탑이나 전신주 등의 송, 배전설비 등에 구비되어 전력선을 주변의 구조물들과 전기적으로 절연시키면서 지지하기 위한 것으로서, 형태에 따라 현수애자, 라인포스트 애자 등으로 구분된다.In general, insulators are provided for transmission and distribution facilities such as steel towers or telephone poles to support the electric power lines while being electrically insulated from the surrounding structures.
애자는 전기적으로 절연특성을 높이고 벌레 등이 전력선 측으로 접근하는 것을 방지하기 위하여 다수개의 스커트부를 갖는 형태로 이루어지는 것이 보통이며, 소재로서는 기존의 자기소재 내지는 전기절연특성 및 기계적특성이 우수하여 운반, 설치가 편리한 폴리머소재 등이 사용되고 있다.The insulator is generally formed in a form having a plurality of skirts in order to increase the electrical insulation properties and to prevent insects from approaching the power line. As a material, the magnetic insulator or electrical insulation and mechanical properties are excellent. Convenient polymer materials are used.
한편, 도 1에 나타난 것과 같이 라인포스트 애자(10)는 다수개의 스커트부(101)가 상하로 연속되는 형태로 이루어져 있으며 상면에는 전력선(5)의 안착을 위한 가이드라인홈(10a)이 형성된 구조로 이루어져 있으며, 전신주 등에 설치된 완금(7)에 수직방향으로 장착된다.Meanwhile, as shown in FIG. 1, the line post insulator 10 has a shape in which a plurality of skirt portions 101 are continuously formed up and down, and a guide line groove 10a for seating the power line 5 is formed on an upper surface thereof. It consists of, and is mounted in the vertical direction on the complete (7) installed in the telephone pole.
이러한, 라인포스트 애자(10)에 의한 전력선 지지구조는, 가이드라인홈(10a)에 전력선(5)이 안착된 상태에서 바인드케이블(bind cable)(12)을 이용하여 라인포스트 애자(10)의 최상단에 구비된 걸림스커트부(102)와 전력선(5)을 묶는 방식으로 이루어져 왔다.The power line support structure of the line post insulator 10 is formed of the line post insulator 10 using a bind cable 12 in a state where the power line 5 is seated in the guide groove 10a. It has been made in such a way to bind the engaging skirt portion 102 and the power line 5 provided at the top.
그러나, 이러한 종래기술에 의하면 전력선(5)이 그대로 외부에 노출되고, 강선(鋼線)이 내재된 구조로 이루어진 바인드케이블(12)의 구조상 먼지와 같은 이물질이 전력선(5)과 바인드케이블(12) 사이에 축적되는 경우, 전력선(5)과 바인드케이블(12) 사이에서 트레킹(tracking)현상(전도체를 감싸고 있는 절연물질에 수분이 섞인 먼지 등이 점착되고 이에 전류가 흘러 주변의 절연물질을 탄화(炭化)시키는 현상)이 발생함으로써 단선사고 등이 유발될 수 있다는 문제점이 있었다.However, according to the related art, foreign matter such as dust in the structure of the bind cable 12 having the structure in which the power line 5 is exposed to the outside and the steel wire is inherent is contained in the power line 5 and the bind cable 12. ) Is accumulated between the power line 5 and the bind cable 12, the dust (water, dust, etc. adhering to the insulating material surrounding the conductor adheres to the carbon, and the current flows to carbonize the surrounding insulating material). (炭化) phenomenon occurs, there is a problem that a disconnection accident can be caused.
또한, 바인드케이블(12)이 풀리어 전력선(5)의 지지상태가 해체되거나 느슨해질 우려가 있다는 문제점도 있었다.In addition, there is a problem that the bind cable 12 may be dismantled or loosened in the support state of the pulley power line 5.
이와 같은 종래기술의 문제점을 해결하기 위하여 도 2에 나타난 것과 같이 커버클램프(14)를 사용하여 전력선(5)을 지지하는 방식이 안출되었다.In order to solve the problems of the prior art, a method of supporting the power line 5 using the cover clamp 14 as shown in FIG. 2 has been devised.
커버클램프(14)는 나사결합에 의해 라인포스트 애자(10)와 조합되어 걸림스커트부(102)와, 이에 접하는 전력선(5)의 부위를 감싸게 된다.The cover clamp 14 is combined with the line post insulator 10 by screwing to enclose the hook skirt portion 102 and the portion of the power line 5 in contact with the line.
따라서, 전력선(5)과 라인포스트 애자(10)의 접촉부위가 외부로 노출되지 않게 됨으로써 바인드케이블(12)을 이용하는 방식 보다 전력선(5)의 지지상태가 안정적으로 유지된다는 특징이 있다.Therefore, since the contact portion between the power line 5 and the line post insulator 10 is not exposed to the outside, the supporting state of the power line 5 is more stably maintained than the method of using the bind cable 12.
그러나, 커버클램프(14)를 이용하는 종래기술에 의하면 커버클램프(14)의 제작에 따른 비용이 많이 소요되고, 커버클램프(14)의 장착 구조가 복잡하기 때문에, 가선작업 내지는 활선작업에서 커버클램프(14)를 분해하고 조립하는 과정에서 작업자의 많은 노력과 주의를 요하게 되는 등, 작업이 어렵다는 문제가 유발된다. However, according to the related art using the cover clamp 14, the cost of manufacturing the cover clamp 14 is high, and the mounting structure of the cover clamp 14 is complicated, so that the cover clamp in the wire work or live work ( 14) In the process of disassembling and assembling, a lot of efforts and cautions of the worker are required.

그리고, 전력선홀더(20)가 장착된 상태에서, 전력선(5)은 상기 압박지지부(24)의 저면에 형성된 다수개 압박돌기(241)에 의해 하방으로 강하게 밀착 압박됨으로써 안착상태가 견고하게 유지되며, 압박돌기(241)는 전력선(5)을 압박한 상태에서 상대적으로 전력선(5)에 의해 압박되어 탄성적으로 변형된다.Further, in the state in which the power line holder 20 is mounted, the power line 5 is tightly pressed downward by a plurality of pressing protrusions 241 formed on the bottom of the pressing support part 24 so that the seating state is firmly maintained. The pressing protrusion 241 is elastically deformed by being pressed by the power line 5 relatively in the state of pressing the power line 5.
상기 압박돌기(241)는 기저부측에서 선단측으로 가면서 면적이 작아지는 형태로 이루어지는 것이 바람직한데, 이 경우에 압박돌기(241)의 선단은 탄력적으로 완만하게 변형이 가능하기 때문에 굵기가 약간씩 다른 전력선에 대해서도 견고한 압박상태를 유지할 수 있게 된다. The pressing protrusion 241 is preferably formed in the form of a small area while going from the base side to the tip side. In this case, the tip of the pressing protrusion 241 can be elastically smoothly deformed, so that the power lines vary slightly in thickness. It is possible to maintain a firm pressure against the.
더불어, 본 발명의 전력선홀더(20)가 라인포스트 애자(10)와 결합된 상태에서는 걸림테두리부(22)가 탄력적으로 강하게 인장되는데, 이러한 전력선홀더(20)의 결합상태에서 강한 바람 등에 의한 진동이 반복적으로 가해지는 경우에도 상기 전력선홀더(20)는 구조적, 형태적 특성에 의해 파열될 우려가 적다고 볼 수 있다.In addition, when the power line holder 20 of the present invention is coupled with the line post insulator 10, the engaging edge portion 22 is elastically strong, and the vibration of the power line holder 20 is caused by strong wind or the like. Even when repeatedly applied, the power line holder 20 may be less likely to be ruptured due to its structural and morphological characteristics.
즉, 구조적으로는 전력선홀더(20)의 걸림테두리부(22)에 여러가닥의 아라미드섬유 소재의 보강코드(26)가 내재되는 특성상, 전력선홀더(20)의 기본소재의 내인장력을 초과하는 충격이 가해지더라도 상기 보강코드(26)에 의해 충분한 내인장력이 유지되기 때문에, 파열될 우려가 감소하게 된다.That is, structurally, the impact of exceeding the tensile strength of the base material of the power line holder 20 in the characteristic that the reinforcing cord 26 of the aramid fiber material is embedded in the hanging edge portion 22 of the power line holder 20. Even if this is applied, since the sufficient tensile strength is maintained by the reinforcing cord 26, the risk of rupture is reduced.
또한, 형태적으로는 걸림테두리부(22)의 외곽이 곡면형태로 이루어지는 특성상, 걸림테두리부(22)의 외곽이 각진형태로 이루어지는 경우에 비해 파열될 우려가 감소하게 된다.In addition, the shape of the outer edge of the engaging edge portion 22 in the form of a curved surface form, the outer edge of the engaging edge portion 22 is less likely to rupture than when the outer edge is formed in an angular form.
반면에 걸림테두리부의 외곽이 각진형태로 이루어지는 경우를 가정하여 보면, 걸림테두리부가 강하게 인장된 상태에서 반복적으로 진동이 가해짐에 따라, 걸림테두리부의 각진 모서리부위에 인장스트레스가 집중됨으로써 모서리부위를 시작으로 균열이 시작되어 파열될 위험성이 커지는 것을 예상할 수 있다.On the other hand, suppose that the outer edge of the hanging edge is formed in an angular shape. As the edge of the hanging edge is repeatedly vibrated while the edge of the hanging edge is strongly tensioned, the edge is started by concentrating the tensile stress on the edge of the edge of the locking edge. This can be expected to increase the risk of cracking and rupture.
본 발명의 다른 실시예에 의한 전력선홀더(20')는, 상기 압박지지부(24)의 양측단에서 서로 대향되는 방향으로 돌출형성된 한쌍의 덮개편(242)을 포함하여 이루어질 수 있다.The power line holder 20 ′ according to another embodiment of the present invention may include a pair of cover pieces 242 protruding in opposite directions from both side ends of the pressing support part 24.
이와 같은 본 발명의 다른 실시예에 의하면, 전력선홀더(20')가 라인포스트 애자(10)에 결합된 상태에서 각 덮개편(242)이 압박지지부(24)와 라인포스트 애자(10)의 걸림스커트부(102) 사이에 형성되는 간극을 덮게 된다.According to another embodiment of the present invention, each cover piece 242 is caught between the pressing support portion 24 and the line post insulator 10 while the power line holder 20 'is coupled to the line post insulator 10. The gap formed between the skirt portions 102 is covered.
따라서, 본 발명의 다른 실시예에 의하면 각종 분진 등의 이물질이 압박지지부(24)와 걸림스커트부(102) 사이의 간극으로 유입되어 적층되는 현상이 발생하지 않으며, 결과적으로 적층된 이물질로 인해 유발될 수 있는 트랙킹 현상의 원인이 제공되지 않기 때문에 절연상태가 더욱 안정적으로 유지된다.Therefore, according to another embodiment of the present invention, foreign matters, such as various dusts, are introduced into the gap between the pressing support part 24 and the latching skirt part 102 so that the phenomenon of stacking does not occur. The insulation state remains more stable because no possible cause of tracking phenomenon is provided.
