Description

송전케이블 코어 및 이를 제조하는 장치{CORE FOR ELECTRICAL POWER TRANSMISSION CABLE AND DEVICE FOR MANUFACTURING THE SAME}Transmission cable core and device for manufacturing the same

본 발명은 송전케이블 코어 및 이를 제조하는 장치에 관한 것이다.The present invention relates to a power transmission cable core and an apparatus for manufacturing the same.

송전케이블은 주로 강심 알루미늄 연선(aluminum conductor steel reinforced, ACSR)으로 만들어진다. 강심 알루미늄 연선은, 도 1에 도시된 바와 같이, 강철 코어(10)와 그 주위를 둘러싼 알루미늄 도체(11)들로 구성된다.Transmission cables are mainly made of aluminum conductor steel reinforced (ACSR). A steel-core aluminum stranded wire, as shown in FIG. 1 , consists of a steel core 10 and aluminum conductors 11 surrounding it.

이러한 강철 코어(10)는 송전케이블의 인장강도를 증가시키나, 송전케이블의 무게를 증가시키고, 송전량 증가에 따른 온도 상승에 의해 늘어나, 송전케이블 전체를 아래로 쳐지게 만든다.The steel core 10 increases the tensile strength of the power transmission cable, but increases the weight of the power transmission cable, and is stretched by the temperature rise according to the increase in the amount of power transmission, making the entire power transmission cable droop down.

이러한 문제를 없애기 위해, 송전탑의 설치 간격을 줄이면, 더 많은 송전탑이 필요하게 되고, 송전케이블의 설치비용도 증가하게 된다.In order to eliminate this problem, if the installation interval of transmission towers is reduced, more transmission towers are required, and the installation cost of transmission cables is also increased.

또한, 강철 코어(10)는 시간이 흐르면 부식되므로, 강도가 점차 떨어지는 문제를 가지고 있다.In addition, since the steel core 10 corrodes over time, there is a problem that the strength gradually decreases.

본 발명에 따른 송전케이블 코어는 탄소섬유를 사용함으로써, 송전케이블의 인장강도가 향상됨과 동시에 무게는 더 가벼워지며, 열에 의한 변형을 줄여 송전케이블의 처짐 현상을 방지한다. 그 결과 송전탑 간격이 늘어나, 송전탑 설치 및 운영비용이 절감된다.The power transmission cable core according to the present invention uses carbon fiber, so that the tensile strength of the transmission cable is improved and the weight is lighter, and the deformation due to heat is reduced to prevent the transmission cable from sagging. As a result, transmission tower spacing is increased, reducing transmission tower installation and operating costs.

또한 탄소섬유와 수지로 구성됨으로써, 충분한 유연성을 가지므로 권취하여 운반 및 보관하는데 용이하고, 부식이 없다. In addition, by being composed of carbon fiber and resin, it has sufficient flexibility, so it is easy to carry and store by winding, and there is no corrosion.

또한, 꼬임형탄소섬유다발에 배치되는 탄소섬유다발에 나선형 꼬임을 줌으로써, 마찰 및 굽힘에 의한 탄소섬유의 파단을 최소화하여 송전케이블을 권취하여 보관 및 운반할 때 송전케이블의 파손을 줄일 수 있다. 여기에 더하여, 꼬임형탄소섬유다발에 배치되는 탄소섬유다발을 직선형탄소섬유다발에 나선형으로 한번 더 감음으로써, 직선형탄소섬유다발와 꼬임형탄소섬유다발의 일체성이 강화되어 송전케이블 코어가 더 견고해진다.In addition, by giving a helical twist to the carbon fiber bundle disposed in the twisted type carbon fiber bundle, it is possible to minimize the breakage of the carbon fiber due to friction and bending, thereby reducing the damage of the transmission cable when the transmission cable is wound and stored and transported. In addition to this, by winding the carbon fiber bundle disposed in the twisted carbon fiber bundle in a spiral once more on the straight carbon fiber bundle, the integrity of the straight carbon fiber bundle and the twisted carbon fiber bundle is strengthened, and the power transmission cable core becomes more robust. .

꼬임형탄소섬유다발(32)들은 직선형탄소섬유다발(31)의 외주면을 따라 일정간격으로 배치된다.The twisted carbon fiber bundles 32 are arranged at regular intervals along the outer peripheral surface of the straight carbon fiber bundles 31 .

꼬임형탄소섬유다발(32)은 서로 꼬인 탄소섬유들로 구성된다. 이렇게 꼬임형탄소섬유다발(32)이 꼬여진 탄소섬유들로 구성되어 있어, 송전케이블 코어(30)의 강도를 높일 수 있다. 또한, 송전케이블을 운반하기 위해 권취롤러에 송전케이블을 권취하는 과정에서, 탄소섬유에 가해지는 힘을 분산시켜, 송전케이블 코어(30)가 터지거나 끊어지는 것을 막을 수 있다.The twisted carbon fiber bundle 32 is composed of carbon fibers twisted together. Since the twisted carbon fiber bundle 32 is composed of twisted carbon fibers, the strength of the power transmission cable core 30 can be increased. In addition, in the process of winding the power transmission cable on the winding roller to transport the power transmission cable, the force applied to the carbon fiber is dispersed, thereby preventing the power transmission cable core 30 from bursting or breaking.

도 2(a) 및 도 2(b)에 도시된 바와 같이, 본 실시예에서는 순번 1 내지 6으로 표시된 6개의 꼬임형탄소섬유다발(32)들이, 직선형탄소섬유다발(31)의 외주면을 따라 서로 일정간격을 두고 평행하게 배치된다. 꼬임형탄소섬유다발(32)의 개수는, 송전케이블 코어(30)의 강도 조절을 위해서, 늘리거나 줄일 수 있다. 탄소섬유들을 서로 꼬아서 꼬임형탄소섬유다발(32)로 만드는 “탄소섬유 꼬임기”에 대한 설명은 후술한다.As shown in Figs. 2 (a) and 2 (b), in this embodiment, six twisted carbon fiber bundles 32 indicated by sequence numbers 1 to 6 are along the outer peripheral surface of the straight carbon fiber bundle 31. They are placed parallel to each other and spaced apart from each other. The number of twisted carbon fiber bundles 32 may be increased or decreased in order to control the strength of the power transmission cable core 30 . A description of the “carbon fiber twisting machine” for twisting carbon fibers together to form a twisted carbon fiber bundle 32 will be described later.

절연부(33)는 직선형탄소섬유다발(31)과 꼬임형탄소섬유다발(32)들 사이를 채우고, 꼬임형탄소섬유다발(32)들의 외주면을 감싼다. 절연부(33)는 액체상태인 열경화성 수지가 직선형탄소섬유다발(31)과 꼬임형탄소섬유다발(32)들 사이로 침투된 후, 열을 받아 경화되어 형성된다. 본 실시예에서 열경화성 수지로 에폭시수지가 사용된다. 이러한 절연부(33)는 직선형탄소섬유다발(31)과 꼬임형탄소섬유다발(32)들이 서로 분리되지 않게 잡아준다. 또한, 꼬임형탄소섬유다발(32)들의 외주면을 감쌈으로써, 송전 케이블의 알루미늄 도체와 탄소섬유 사이를 절연시킨다.The insulating portion 33 fills between the straight carbon fiber bundles 31 and the twisted carbon fiber bundles 32 , and surrounds the outer peripheral surfaces of the twisted carbon fiber bundles 32 . The insulating part 33 is formed by penetrating the liquid thermosetting resin between the straight carbon fiber bundles 31 and the twisted carbon fiber bundles 32, and then curing it by receiving heat. In this embodiment, an epoxy resin is used as the thermosetting resin. The insulating portion 33 holds the straight carbon fiber bundle 31 and the twisted carbon fiber bundle 32 not to be separated from each other. In addition, by wrapping the outer circumferential surface of the twisted carbon fiber bundles 32, the aluminum conductor of the power transmission cable and the carbon fiber are insulated.
