Description

지중 송전케이블 보호관{GUIDE PIPE FOR POWER TRANSMISSION CABLE IN THE UNDERGROUND}Underground transmission cable sheath {GUIDE PIPE FOR POWER TRANSMISSION CABLE IN THE UNDERGROUND}

본 발명은 지중 송전케이블 보호관에 관한 것으로, 더욱 상세하게는 다수의 송전 케이블을 격리 배선하여 케이블들의 엉킴 등을 방지하고, 케이블을 쉽게 배선 및 인출할 수 있도록 한 지중 송전케이블 보호관에 관한 것이다.
The present invention relates to an underground transmission cable protection tube, and more particularly, to an underground transmission cable protection tube that can be easily wired and drawn out to prevent tangling of the cables by isolating and wiring a plurality of transmission cables.

일반적으로 우리나라의 가공배전선지중화는 1973년 효자동에서 광화문구간까지 복잡하게 시설되어 있는 배전선을 전선정비측면에서 간선도로변의 전주를 뒷골목에 이설, 저압케이블을 사용 주상변압기로부터 인근 수용가를 공급함으로써 시작되었으며, 그 이후 다음과 같이 계획되어 확장되고 있다.In general, Korea's overhead distribution line processing began in 1973 by distributing the distribution lines, which were intricately installed from Hyoja-dong to Gwanghwamun, by relocating Jeonju along the main road to the back alley from the side of cable maintenance, and supplying nearby customers from low-voltage cables using low-voltage cables. Since then, it has been planned and expanded as follows.

참고로 지중 선로 공사방식은 크게 직매식과, 관로식 그리고, 전력구식으로 나눌 수 있다. 여기서, 관로식은 합성수지관, 강관, 흄관 등 관재(pipes)를 사용하여 관로를 구성한 후 케이블을 부설(敷設)하는 방식으로써, 일정 거리의 관로 양끝에는 맨홀을 설치하여 케이블을 설치하고 접속한다.For reference, underground construction works can be divided into direct sales, pipelines, and electricity. Here, the pipeline type is a method of laying a cable after pipes are constructed using pipes such as synthetic resin pipes, steel pipes, and fume pipes.

이러한, 관로식 공사에 사용되는 관로는 케이블 회선수가 3회선 이상 9회선 미만이거나, 장래 회선증설이 예상되는 경우에, 도로예정지역으로 도로포장계획이 있는 경우에, 직매식이 불리한 경우에, 합성수지관, 강관, 흄관 등과 같은 관재(pipes)가 주로 이용되었는데, 이러한 관재는 지금까지 매우 단순한 형태로 제작되어 있어 실사용시 여러 가지의 문제점을 제공하였는바, 첫째로는 단순히 관재 상호간을 볼트와 너트로 체결하여 관로를 형성함에 따라, 초기 관로 상태를 장기간 견고히 유지할 수 없는 문제점이 있었다. 즉, 상술한 바와 같이 관재의 연결을 단순히 볼트와 너트를 사용하여 연결하고 있으므로 실사용시 토압에 의해 상호간의 연결부위가 단락되는 현상이 자주 초래되었기 때문이다.Such pipes used for pipeline construction are synthetic resin pipes when direct cable type is unfavorable when the number of cable lines is more than 3 lines or less than 9 lines, or when the line expansion plan is expected in the future, when there is a road paving plan in the planned area. Pipes such as steel pipes and fume pipes were mainly used, and these pipes have been manufactured in a very simple form so that various problems have been provided in actual use. Firstly, the pipes are simply fastened with bolts and nuts. As the conduit was formed, there was a problem that the initial conduit state could not be firmly maintained for a long time. That is, because the connection of the pipe as described above simply by using a bolt and nut, the phenomenon that the connection between the short circuit between each other due to the earth pressure when the actual use was often caused.

둘째로는 맨홀과 맨홀 사이에 정 위치된 관로와 이 관로 내에 위치된 지중 케이블이 온도 변화에 따라 신축 변화할시 이에 대한 대응책이 전혀 마련되어 있지 않아 연결 부위의 파손과 단락이 자주 초래되는 문제 현상과 더불어 지중 케이블의 단선이 자주 초래어 선로 장애가 발생되는 문제점이 있었다.Second, there is no countermeasure when the pipeline located between the manhole and the manhole and the underground cable located in the pipeline changes and contracts according to temperature changes. In addition, there was a problem that the line failure occurs frequently caused underground cable disconnection.

셋째로는 내측이 단순 관통된 형상을 취하고 있어, 내측에 배선되는 지중 케이블간의 마찰 현상이 초래되어 선로 장애를 유발시키는 문제점이 있었다.Third, since the inside has a simple through shape, friction between underground cables that are wired inside causes a problem of causing a line failure.

넷째로는 상술한 문제점들로 인해 해마다 막대한 유지 보수 비용을 책정해야 하는 매우 비경제적인 문제점이 있었다.Fourthly, due to the problems described above, there is a very uneconomic problem that requires a huge maintenance cost each year.

이런 종래의 문제점들을 해결하기 위하여, 지중 케이블을 보호하기 위한 지중 송전케이블 보호관의 기술이 제안된 바 있다.In order to solve these conventional problems, a technique of underground transmission cable sheaths for protecting underground cables has been proposed.

종래 기술에 의한 지중 송전케이블 보호관은, 단순히 케이블을 내부에 삽입 배선하여 외부와 차단함으로써 보호하는 것일 뿐이며, 케이블의 유지보수를 감안하지 못하여 케이블의 유지보수시 케이블을 일측에서 타측으로 인출하여야 하는 불편함이 있고, 다수의 케이블들을 서로 구획하지 못하여 케이블들이 엉키면서 단선 등이 발생되는 문제점도 있다.
