전력 공급용 복합 전력케이블 { A Complex Cable For Supplying The Electric Power }A Complex Cable For Supplying The Electric Power

본 발명은 전력케이블에 관한 것으로, 특히, 전력케이블의 내부에 전력선을 설치하고, 상기 전력선이 중심부분에 온도에 따라 파손여부를 감지하는 온도센서감지센서선을 설치하도록 하고, 상기 전력선과 외장철선 사이에 다수의 데이터통신선을 설치하므로 케이블의 유지보수 비용을 저감하고, 온도데이터를 이용하여 케이블 송전용량을 정확하게 계산하도록 하는 전력 공급용 복합 전력케이블에 관한 것이다.The present invention relates to a power cable, and in particular, to install a power line in the interior of the power cable, and to install a temperature sensor detection sensor line for detecting whether the power line is damaged according to the temperature in the central portion, the power line and the external wire The present invention relates to a composite power cable for power supply, which reduces the maintenance cost of a cable by installing a plurality of data communication lines therebetween, and accurately calculates cable transmission capacity using temperature data.

일반적으로, 광케이블은, 전송용량을 늘리기 위하여 여러 줄의 광섬유를 합쳐서 한줄로 만들어준 케이블로서, 광섬유가 배열되는 상태에 따라서 루즈튜브형과, 리본형등이 있다.In general, an optical cable is a cable made by combining several lines of optical fibers in order to increase transmission capacity, and there are a loose tube type and a ribbon type depending on the arrangement of the optical fibers.

상기 광케이블은 야외 혹은 지중선으로 사용되면서 필요한 정보를 사용자에게 대량으로 전달하도록 하는 전선의 일종으로서, 최근 들어서 급속하게 진일보하고 있는 통신구성요소의 일종이다.The optical cable is a kind of electric wire which is used outdoors or underground lines to transmit a large amount of necessary information to the user, and is a kind of communication component that is rapidly advanced in recent years.

그리고, 광섬유가 한가닥 이상씩 종입되어지는 광섬유번들튜브 다수개를 한 곳으로 모아 두고서 그 외부로 중심튜브, 보조인장재 및 폴리에틸렌(Polyethylene) 시스로 된 외피층등을 순차적으로 감싸서 형성되어지는 번들튜브형 광섬유케이블이 있다.In addition, bundle tube type optical fiber cables are formed by gathering a plurality of optical fiber bundle tubes into which a fiber is inserted one or more strands in one place, and then wrapping the outer tube made of a central tube, auxiliary tensile material and a polyethylene sheath. There is this.

도 1은 종래의 전력 공급용 케이블의 단면도이고, 도 2는 종래의 복합케이블을 이상 유무 검지장치로 이상 여부를 파악하는 그래프를 보인 도면이다.1 is a cross-sectional view of a conventional power supply cable, Figure 2 is a view showing a graph to determine whether or not a conventional composite cable abnormality detection device.

종래의 전력 케이블(2)의 구성을 살펴 보면, 외피부분에 강도를 유지하고 파손을 방지하기 위한 외장철선(4)과; 상기 외장철선(4)의 내부에 전기를 공급하기 위한 전력선(6)과; 상기 전력선(6)의 외측과 상기 외장철선(4) 사이에 설치되어 전력케이블(2)의 이상여부를 판단하는 광섬유 검지선(8)과; 상기 광섬유 검지선(8)을 통하여 이상 여부를 판단하는 이상유무검지장치(10)등으로 이루어진다.Looking at the configuration of the conventional power cable (2), and the outer wire (4) for maintaining the strength in the outer skin portion and preventing damage; A power line 6 for supplying electricity to the outer wire 4; An optical fiber detecting line (8) installed between the outside of the power line (6) and the sheathing wire (4) to determine whether the power cable (2) is abnormal; The abnormality detection device 10 and the like for determining whether or not the abnormality through the optical fiber detection line (8).

상기 전력케이블(2)을 지중이나 해저등지에 매설하여 사용하는 비정상적인 환경에 의하여 전력케이블(2)의 외장철선(4)이 파손되어져서 해수등이 침입하거나 절단에 의하여 파손된 경우, 광섬유 검지선(8)에서 이상 유무를 판단하게 된다.When the external steel wire 4 of the power cable 2 is damaged due to an abnormal environment in which the power cable 2 is buried in the ground or the sea, etc., seawater or the like is broken or damaged by cutting, an optical fiber detecting line ( In 8), it is determined whether there is an abnormality.

상기 광섬유 검지선(8)이 파손, 절단되어진 경우에 이상유무검지장치(10)에서 이상유무를 검지하여 판단하게 되고, 도 2에 도시된 바와 같이, 이상지점에서 검지신호의 값이 급격하게 저하되는 것을 알 수 있으며 그 검지신호를 바탕으로 이상지점에서 파손 및 절단된 전력케이블(2)을 수리하도록 한다.When the optical fiber detection line 8 is broken or cut, the abnormality detecting device 10 detects the abnormality and determines the abnormality. As shown in FIG. 2, the value of the detection signal is suddenly lowered at the abnormal point. It can be seen that based on the detection signal to repair the broken and cut power cable (2) at the abnormal point.

그런데, 상기한 바와 같이, 종래에는 전력수송과 케이블의 이상점의 감시용도로는 사용이 가능하나, 해저통신용케이블과 도체온도를 추정하는 용도로는 동시에 사용하기 어려운 구조 및 배치를 지니고 있었다.However, as described above, in the related art, although it can be used for power transport and monitoring of abnormal points of the cable, it has a structure and arrangement that are difficult to use simultaneously for estimating the cable for the submarine communication and the conductor temperature.

또한, 해저 전력케이블과 해저 통신케이블을 따로 포설하기 때문에 포설비용이 과다하게 발생하는 단점이 있었으며, 케이블의 송전용량을 정확하게 계산하기 위하여 필요한 케이블의 중심부분의 온도데이터를 수집할 수 없는 문제점을 지닌다.In addition, since the installation of the submarine power cable and the submarine communication cable separately, there is a disadvantage that excessive use of the installation equipment, and there is a problem that can not collect the temperature data of the center of the cable required to calculate the cable transmission capacity accurately .

특히, 종래에는 해저 전력 케이블과 광통신용 해저케이블을 각각 따로 포설하는 경우, 포설기간이 2배로 늘어 나고, 자재비용도 광통신케이블에 대한 외장용철선을 따로 사용해야 하므로 약 30%정도 추가비용이 발생한다.In particular, when the submarine power cable and the optical communication submarine cable are separately installed in the related art, the installation period is doubled, and the material cost is additionally generated by about 30% because the external wire for the optical communication cable must be used separately.

본 발명은 이러한 점을 감안하여 안출한 것으로서, 전력케이블의 내부에 전력선을 설치하고, 상기 전력선이 중심부분에 온도에 따라 파손여부를 감지하는 온도센서감지센서선을 설치하도록 하고, 상기 전력선과 외장철선 사이에 다수의 데이터통신선을 설치하므로 케이블의 유지보수 비용을 저감하고, 온도데이터를 이용하여 케이블 송전용량을 정확하게 계산하도록 하는 것이 목적이다.The present invention has been made in view of this point, to install a power line in the interior of the power cable, and to install a temperature sensor detection sensor line for detecting whether the power line is damaged according to the temperature in the center portion, the power line and the exterior Since many data communication lines are installed between wires, the purpose is to reduce cable maintenance costs and to accurately calculate cable transmission capacity using temperature data.
