Description

배전선로의 볼형 분기슬리브{Ball-type branching sleeve to power distribution line}Ball-type branching sleeve to power distribution line}

본 발명은 배전선로의 볼형 분기슬리브에 관한 것으로서, 보다 상세하게는 부품수가 적어 조립구조가 간단하고 시공작업시 작업공수가 적으며 이에 따라 고공에서의 작업자 작업시간이 단축되어 안전사고의 위험이 저하되고 외부충격에 의해 주선과 인하선의 분리가 구조적으로 어려워 결합력이 보강되는 배전선로의 볼형 분기슬리브에 관한 것이다. The present invention relates to a ball-type branch sleeve of a distribution line, and more specifically, the number of parts is small, so that the assembly structure is simple, and the number of working hours during construction work is reduced. Accordingly, the operator's working time at high altitude is shortened, thereby reducing the risk of safety accidents. And it is structurally difficult to separate the main line and the down line due to external impact, so that the bonding force is reinforced.

일반적으로 전선케이블의 연결부위 및 접속부분은 절연이 가능하도록 테이프를 접착시키거나 절연체로 케이블의 노출부위를 격리하도록 하였으나, 이는 쉽게 접속부위가 벗겨지거나 훼손될 뿐만 아니라, 수분이 접촉하게 되면 누전 또는 감전사고의 위험도 뒤따랐기 때문에 안전성에 문제점이 있었다. In general, the connection part and the connection part of the electric wire cable are attached with tape to enable insulation or the exposed part of the cable is insulated with an insulator, but this is not only peeled or damaged, but also when moisture comes in contact with it, a short circuit or There was a problem with safety because the risk of electric shock was also followed.

그래서, 근래에 들어 안전성을 고려하면서도 연결부위의 부식을 방지하도록 전선 접속부분을 완전히 밀폐하는 여러 형태의 전선 분기용 슬리브 등이 제공된 바 있었다. Thus, in recent years, various types of sleeves for electric wire branching have been provided to completely seal the electric wire connection portion to prevent corrosion of the connection portion while considering safety.

그러나, 종래의 분기슬리브는 전선케이블과의 연결부위 접지면이 작기 때문에 인장력이 약하여 슬리브 내에서 전선케이블이 쉽게 미끄러져 빠져나올 수 있었으며, 작은 접지면적에 의해 접속부위의 온도가 쉽게 상승하여 전선케이블 피복이 녹거나 타게 되어 안전사고를 유발하게 되는 문제점이 있었다. However, since the conventional branch sleeve has a small ground plane at the connection part with the wire cable, the tension force is weak, and the wire cable can easily slide out of the sleeve. The temperature of the connection part easily rises due to the small ground area. There was a problem in that the coating melted or burned, causing a safety accident.

또한, 시공 접속부위가 쉽게 부식되어 접촉저항을 증가시키고 다시 접속부위의 온도가 상승되어 전해 부식을 가속화하는 과정이 반복됨으로서, 최종적으로 단선 사고 등을 일으키게 되는 문제점이 있었다.In addition, there is a problem in that the process of accelerating electrolytic corrosion is repeated because the construction connection part is easily corroded to increase the contact resistance and the temperature of the connection part is raised again, resulting in a disconnection accident.

이런 문제점을 해결하기 위하여, "정면이 ∩형상의 관체로 하단 중심에는 상부내측으로 내측나사부를 갖는 좌우측체결홀이 각각 형성되고, 상부전후방측으로는 전후방측조임장공이 각각 상하부로 형성되며, 전후방측조임장공 좌우측 하부에는 승강장공이 각각 형성되어 전후방측조임장공에 각각 위치된 조임와이어의 양단이 고정되는 승하강고정구가 각각 형성되되 승하강고정구 하단에는 몸체 하단의 나사홀에 나사결합되어 승강장공으로 돌출된 레버의 볼트부 선단이 공회전가능하게 고정되고, 몸체 내주연에 배전선로가 위치되는 상부보호틀과; 상기 상부보호틀 하부내측으로 삽입되는 틀체로, 상면에는 배전선로 하부가 안착되는 반원홈이 형성되고, 반원홈 중심에는 피복이 제거된 배전선로 내측에 밀착되어 통전이 이루어지는 통전돌부가 형성되되 통전돌부에는 내측의 스프링에 의해 상부로 탄성돌출되는 다수 개의 통전핀이 형성되며, 좌우측면 상측에는 좌우측으로 돌출되어 상기 좌우측체결홀에 삽입되는 좌우측걸림돌부가 형성되고, 하면에는 피복이 제거된 인하선 선단이 안착되는 통전판이 위치되되 통전판은 통전선에 의해서 통전핀과 통전이 이루어지며, 통전판에 안착된 인하선은 고정판에 의해 체결고정되는 슬리브몸체와; 상기 상부보호틀의 좌우측체결홀에 나사결합되는 외측나사부를 갖고 상기슬리브몸체의 좌우측걸림돌부를 하측에서 상부로 밀어 상기 통전돌부의 통전핀을 배전선로의 피복이 제거된 부분에 밀착고정시키는 통전볼트를 구비하는 배전선로의 분기슬리브."가 특허등록 제10-0835578호(2008.06.05. 공고)가 개시된바 있었다.In order to solve this problem, "the front is a ∩-shaped tube body, and in the center of the lower end, each of the left and right fastening holes having an inner thread in the upper inner side, and the front and rear tightening holes are formed in the upper and lower parts respectively, and the front and rear sides A lifting hole is formed in the lower left and right sides of the tightening hole, and a lifting fixture is formed to fix both ends of the tightening wires respectively located in the front and rear tightening holes.At the bottom of the lifting fixture, screwed into the screw hole at the bottom of the body and protruded into the lifting hole. An upper protective frame in which the front end of the bolt portion of the lever is fixed so as to be capable of idling, and the distribution line is located at the inner periphery of the body; a frame body inserted into the lower part of the upper protective frame, and a semicircular groove is formed on the upper surface in which the lower part of the distribution line is seated. In the center of the semicircular groove, a conductive protrusion is formed in close contact with the inside of the distribution line from which the covering is removed to conduct electricity, but a plurality of conductive pins elastically protruding upward by the inner spring are formed in the conductive protrusion. The left and right locking protrusions protruding into the left and right side fastening holes are formed, and on the lower surface there is a current plate on which the tip of the down line with the cover removed is seated, but the current plate is energized with the current pin by the current line. The seated down line has a sleeve body that is fastened and fixed by a fixing plate; and has an outer screw part screwed into the left and right fastening holes of the upper protection frame, and pushes the left and right locking protrusions of the sleeve body from the lower side to the upper side to push the energizing pin of the conductive protrusion. A branch sleeve of a distribution line provided with a energizing bolt that adheres to the part where the cover of the distribution line is removed. Patent Registration No. 10-0835578 (Announcement on June 5, 2008) was disclosed.

그러나, 이런 종래의 분기슬리브는, 인하선과의 연결부위 접지면이 크고 착탈식의 시공작업으로 이루어지는 반면에, 조립구조가 너무 복잡하여 작업자의 시공작업시 작업공수가 많아 고공에서의 작업자 작업시간이 많이 소요되어 안전사고의 위험이 증대되고, 외부충격에 의해 주선에서 인하선이 손쉽게 분리될 위험이 존재하는 구조적인 문제점이 있었다.However, such a conventional branch sleeve has a large ground plane and a detachable construction work, whereas the assembly structure is too complex, so the number of work man-hours during the construction work of the worker is large, and the work time of the worker in high altitude is large. There is a structural problem in that the risk of safety accidents is increased due to the need, and there is a risk that the downline is easily separated from the main line by an external shock.
